#rockbox log for 2007-10-18

00:00:03safetydanpreglow, oh yeah, I remember you talking about that at some point. Definitely a good idea to keep the frequencies out of it. They can always go in the manual if someone really wants to know
00:00:57BonBonTheJonmy ipod 4g won't boot rockbox, I get a checksum error
00:01:02 Quit davina ("xchat on Ubuntu 7.04")
00:01:30preglowsafetydan: yeah, and like i said, if we want to change sample rates on the hw side at some point, they're not going to be correct, and i don't know if i can be bothered to supply a full (calculated) list in the manual
00:01:44preglowsafetydan: if you want frequency exact controls, you should be using sweq
00:01:47krazykitBonBonTheJon, sounds like you need to download a new build and update.
00:02:15preglowsafetydan: i'm thinking perhaps something like "1 (lowest), 2, 3, 4 (highest)" for the video, perhaps
00:02:20BonBonTheJonkrazykit: I used the rbutil-qt to do the full install and small install, both times I get the error
00:02:23preglowand just "low, high" for the targets that only have two choices (most)
00:02:48 Quit donutman25 ("Konversation terminated!")
00:03:05safetydanpreglow, sounds good to me. I'll see what I can do
00:03:14preglowsafetydan: sweet
00:03:58krazykitBonBonTheJon, well, how about you try doing it manually? download the latest build and unzip it to the root of your ipod's drive
00:04:19BonBonTheJonkrazykit: I'm busy now, but I'll try it when I get back home
00:05:22preglowamiconn: some eu person is lending his nano away on the ml (hint, hint) ;)

00:10:07AppleOSHelpplzHI - I have a 5.5g iPod and want to have Apple OS and Rockbox on it and I am using Loader 2.5 and when ever i select Apple OS from the menu it just resets to the loader 2.5 menu
00:10:33krazykitAppleOSHelpplz, loader2 is not supported here. ask the ipodlinux channel for that.
00:10:55 Quit roolku ()
00:11:05AppleOSHelpplzok thank you, does the rockbox loader support Apple OS loading?
00:11:13preglowyes

00:14:10courtcDo you guys get a lot of loader2 questions?
00:14:27krazykitnot a ton, but loader2 is not supported by rockbox
00:14:38 Nick sup_ is now known as sup (i=1000@80.216.235.247)
00:14:46courtcRight.
00:15:00bluebrotherthe manual tells how to load AppleOS using the Rockbox bootloader ...
00:15:04safetydananyone ever looked at using llvm instead of gcc?
00:15:09courtcIt's not a rockbox project, I wouldn't expect it to be.
00:15:17preglowsafetydan: why would we?
00:15:55safetydanpreglow, it's supposed to be substantially better at optimising
00:16:46amiconnAnd it's substantially more limited in target support...
00:16:51amiconnJust a quick glance
00:17:05preglowsafetydan: that would surprise me a great deal
00:17:47safetydanamiconn, true that
00:17:50 Quit lee-qid ("aufwiederbyebientotsayonara")
00:17:56preglowof its targets, only arm is covered
00:18:01preglowwe need sh and coldfire too :/
00:19:40markunpreglow: we could at least try llvm for arm with the gcc frontend
00:19:50 Quit Rob2222 ()
00:19:54preglowmarkun: sure, would be interesting
00:20:31safetydanI see it was proposed as a gsoc project even
00:20:55markunit looks like the llvm guy actually listen to complaint and look at patches, perhaps we could persuade amiconn to write a coldfire or sh1 backend ;)
00:21:25amiconnNo, thanks
00:22:01 Quit BigMac ("Leaving")
00:22:16markunamiconn: you probably said the same about mpegplayer optimisations a few months ago :)
00:22:39preglowyeah, i didn't see that coming :P
00:23:12courtcWell... I'll look into llvm... We only have on arch ;)
00:23:16courtcone*
00:23:38amiconnmarkun: That's not true - I wanted this cf asm idct going in, but first didn't understand at all how it worked
00:24:23amiconnAnd nobody else did it in the meantime, so I started to look into it thoroughly
00:24:30AppleOSHelpplzok so i want to use the rockbox loader but when i browse to where my .ipod file is it doesn't show it whats up?
00:25:04amiconnWhile I only use a small subset of all rockbox features, I hate it when there are half-working ones

00:26:38 Quit elinenbe (Read error: 110 (Connection timed out))
00:26:41amiconnIt's still not optimal, but at least it's usable on X5 now
00:26:45AppleOSHelpplzI want to be able to load the defaut apple firmware from rockbox (or before rockbox loads) so that i can switch between the two
00:27:03amiconnAnd if we get this codec stack seize in, there is potential for an extra 10% speedup
00:27:10bluebrotherwell, read the manual. It explains how to do this.
00:27:19sarixe2 bugs to report: one, when i start up rockbox and resume playback from when i turned it off, the song doesn't start at the beginning, but rather a fraction of a second ahead.
00:27:27bluebrother... and we expect you to search the manual before asking for support.
00:27:28 Join Zagor [0] (n=bjst@46.35.227.87.static.tab.siw.siwnet.net)
00:27:30AppleOSHelpplzRockbox is able to load and start another firmware file without rebooting. You just “play” a file with the extension .ipod
00:27:36AppleOSHelpplzright from the manual
00:27:44amiconnI wonder how much it would help to convert the other motion compensation functions to asm
00:28:02sarixetwo, recently, when i shut off rockbox, instead of shutting down promptly, it says "Shutting Down..." and starts to play the song i was listening to.
00:28:07amiconnIt would help to have statistics of a few videos
00:28:08bluebrotherAppleOSHelpplz: well, that tells about "another firmware". It also tells you how to start the original firmware.
00:28:17sarixethen after a few seconds, it stops and shuts down.
00:28:54 Quit billytwowilly (No route to host)
00:28:57amiconnThe simple block move is obviously used most, and half-pixel motion isn't used much (is it used at all in elephants dream?)
00:29:10bluebrotherthere is even a section about it. http://download.rockbox.org/manual/rockbox-ipodvideo/rockbox-buildch3.html#x5-280003.1.3
00:29:11amiconnBut how about the destination averaging variants?
00:30:04 Quit ompaul (Client Quit)
00:32:36preglowamiconn: well, some statistics should be quickly gathered by just inserting some printfs and massaging the output
00:32:46preglowamiconn: just make sure to get videos produced by different encoders

01:10:09amiconnHow does one figure out that kind of algorithm?
01:10:44preglowi have no idea
01:10:44preglowheh
01:10:51preglowsafetydan: didn't expect that much

01:22:56preglowiamben: understandable, but we like the benefits of using the same communications channels as users when possible
01:23:06amiconnpreglow: How would I know? I don't know what you're doing...
01:23:36preglowmentioned it ten minutes ago: i just coded a routine that multiplies two signals and adds it back to an array in coldfire asm
01:23:58preglowstandard emac fare
01:24:23amiconnYes, and that still tells me next to nothing about timing behaviour
01:24:49amiconnInstruction order is sometimes important, especially regarding emac
01:25:35preglowit's just movem.l, movem.l, macx2, movclr.lx2, add-with-memx2, rinse and repeat
01:25:37iambeni used to be a comp eng major, but i quit... so i understand SOME things
01:25:55preglowthere is some stall, no stall, since i need to increment addresses for movem.l

01:33:58amiconnpreglow: If you put movclr directly after mac, you'll have a 2-cycle stall
01:34:31preglowamiconn: i have two addq there, exactly enough to eat up the stall
01:34:32amiconnTry to put 2 instructions inbetween to avoid that
01:34:44preglowamiconn: i was the first person to know this, you don't need to tell me :)
01:35:24amiconnNext candidate is the movem. Line fetches are faster, unless the data is in iram
01:35:49preglowsince the two sample loop is as fast as the four sample one, i belive it is
01:36:22preglowahh, i can optimize further, the block length is always power of two

02:02:14preglowamiconn: yet another test, getting rid of one movem.l and instead fetching values in parallel with mac.l proved a teeny bit faster as well
02:03:27amiconnYou save one cycle per loop with iram data
02:04:26preglowbeh, it's not consistent
02:04:40preglowthink i'll just go with the extra movem.l since that makes for the smaller code
02:04:43amiconnmovem.l needs n+1 cycles for n longwords
02:05:16amiconnmac.l with parallel load needs one extra cycle for the load

02:33:28jhMikeSah, though you meant thread turnaround
02:33:30preglowoh, i mean 1.33
02:33:34preglowno, that would suck
02:33:42preglow1.33 ms is 64 samples
02:33:57jhMikeSnot much more than a HW FIFO
02:34:38preglowi did a test setup running ambisonics encoding on three sources, ninth order (19 channels), decoding to 16 speakers with metering on all channels, all the while tweaking source positions
02:34:45preglownot a glitchj
02:34:50preglownever thought i'd see linux do that
02:35:22jhMikeSheh, but I'm sure there a little more computing power. unless iPL Realtime did this. :P
02:35:31preglowhaha, indeed
02:35:45preglowbut that's quite a shitload of computation anyway
02:36:10preglowi wonder how the hell they manage being able to preempt important stuff
02:36:14TMMyeah, I hate that :P
02:36:23preglowapparently they even preempt critical sections and stuff
02:36:34TMMhow can you preemt critical sections?
02:36:38preglowi don't know...
02:36:39preglowi just read it
02:36:40jhMikeSummm...interrupts?
02:36:45TMMisn't that the point of 'critical'?
02:37:02jhMikeSyou can preempt them, just not reenter them
02:37:06TMMcritical sections can't be interrupted can they?
02:37:17TMMaren't they supposed to be atomic?
02:37:22preglowjhMikeS: but that'll leave them in pretty inconsistent state, no?
02:38:03preglowoh well, i'll leave all this stuff to you :P
02:38:14TMMthat won't work... unless they aren't very critical :)
02:38:19jhMikeSshouldn't matter as long as they're not altered. I think they must mean that quantums are disabled as short a time as possible. Don't know for sure though.
02:38:47preglowlinux always used to have trouble with long critical sections
02:38:47TMMwho does this anyway?
02:39:06preglowTMM: ingo molnar's realtime patch for linux
02:39:27TMMyou can't interrupt linux's critical section
02:39:33preglow*shrug*
02:39:35preglowdon't ask me
02:39:44amiconnpreglow: You sure this cf asm is correct?
02:39:50preglowamiconn: it works
02:39:52TMMI thought some outlandish OF or something did this :)
02:39:54preglowamiconn: anything special?
02:40:03amiconnmovem load order is fixed, first d0..d7 then a0..a7
02:40:06jhMikeSpreglow: ?? Is there some other object besides a mutex? preeption of course can happen inside the guarded core or else you wouldn't need the guarded code.
02:40:21preglowamiconn: of course
02:40:30preglowamiconn: then no, that isn't correct at all
02:40:34amiconnmovem.l (%[w]), %%a0-%%a1/%%d4-%%d5
02:40:38preglowi'll fix
02:40:52preglowsounds fine, though :/
02:41:02jhMikeSthe linux scheduler must be really weird then
02:41:49preglowgetting tired now, didn't think of that at all
02:41:51TMMjhMikeS: I'm fairly confident that (on x86) interrupts are disabled during those sections
02:42:41*amiconn wished several times that the movem load order would be switchable :/
02:43:12preglowamiconn: i want the update base reg functionality more
02:43:21preglowjhMikeS: there's some talks of spinlocks being preemptive
02:43:33preglowdon't really know what that signifies
02:44:19preglowamiconn: changing order of movem.l address range and changing order in mac.l should make it right, yes?

02:45:59jhMikeSpreglow: seems odd they wouldn't allow spinlock preemtion in general.
02:46:30*jhMikeS will go look at linux kernel source at some point
02:46:48preglowarghghghg
02:46:49TMMjhMikeS: linux has had problems with locking on the past, the whole preemtive patchset should illustrate that nicely
02:47:02preglowTHIRD bloody time i have to paperclip my h12
02:47:03preglow0
02:47:14preglowsometimes if you skip too fast, it just locks
02:47:17jhMikeSh12-0? hehe
02:47:34preglowannoyed and writing :/
02:47:42TMMnow, THAT would be an interesting molecule :P
02:48:19jhMikeShah
02:49:21preglowman, i like coldfire asm
02:49:25preglowso much cooler than arm asm :P
02:49:27TMMdoes anyone know of an 'ease yourself into arm assembly' manual? I'm getting very confused by stuff like eor r0, r1, lsl r3 :)
02:49:57TMMmakes me wish for x86... well, minus mmx
02:49:57preglowjhMikeS: The real-time preemption patch set seeks to provide deterministic response times with a stock Linux kernel. It works by making everything preemptable, including code (spinlock-protected critical sections, interrupt handlers) which cannot be preempted in current kernels.
02:49:57jhMikeSpreglow: I don't know. If you took the best of ARM and CF in one instruction set...
02:50:02preglowjhMikeS: got it from there
02:50:08preglowjhMikeS: that would rock indeed...
02:50:14preglowjhMikeS: but i love the fact it's not load-store
02:50:41preglowTMM: man, x86 asm sucks
02:50:43TMMpreglow: wouldn't it be hugely expensive to preserve state across those sections?
02:50:49preglowTMM: shrug
02:50:51TMMpreglow: x86 asm is EASY
02:51:04jhMikeSif CF had a shifter like ARM, and condition execution, conditional status, that would be most of what's best about ARM
02:51:06preglowTMM: and sucks, few operands, few registers, retarded instruction behaviour in places
02:51:06TMMpreglow: ugly as fuck, but EASY :)
02:51:29preglowlike BOUND, now there's an instruction for you
02:51:43TMMpreglow: do you know of a nice guide with examples? :)
02:51:43jhMikeSBOUND? A memory-barrier instruction?
02:52:22preglowjhMikeS: afaik, it checks if a certain pointer address is within certain bounds, and throws an interrupt if not
02:52:30preglowjhMikeS: the same interrupt used for print screen under dos....
02:52:33*jhMikeS got sick of looking at x86 crap a long time ago
02:52:49TMMbound's just used to do some sanity checking on pointers
02:52:56preglowjhMikeS: best of all, return address would be set to the bound instruction, so it would just trigger and trigger and trigger
02:53:15preglowresult would be that you'd hear BEEP BEEP BEEP BEEP and the printer warming up if you executed some bad code
02:53:23jhMikeSlol
02:53:30preglowlol indeed
02:53:40preglowi learned to associate the printer warming up with me fucking up
02:53:44jhMikeSsome time after that PortalPlayer was founded, right? :P
02:53:46preglowsince i had long sinced cut the pc speaker wire
02:54:11TMMO come on, you can use it for cheap segfaults
02:54:41jhMikeSat least lock xchg works there, or maybe?
02:54:51preglowlock works with plenty of instrs
02:55:02preglowx86 has tons of memory barrier instructions
02:55:05preglowit's good for that
02:55:18preglowthat is, lock is the memory barrier
02:55:20jhMikeSI'm just wondering if the guys who implemented BOUND implemented SWP on PP :P
02:55:22preglowbut it works with lots of instructions
02:55:55preglowthey had probably drunk the same amount of whisky anyway
02:56:08TMMI don't disagree that x86 sucks, I'd like to transcend into arm, does any of you know of a good way to learn it? :)
02:56:11TheDarkOnehow does rockbox estimate battery time remaining?
02:56:20TheDarkOnebecause it seems to be completely off lol
02:56:25TMMTheDarkOne: depends on the target
02:56:33preglowTMM: i found it really easy to get into, and i just got the quick reference sheet
02:56:45jhMikeSI wouldn't mind ARM with a lock prefix

02:59:35preglowwould be cool, yeah
02:59:50preglowthis is why i hate load-store
03:00
03:00:58TMMthat's ONE instruction?

04:23:09TMMif I might drop a suggestion, as one of the worst offenders of both off topic conversations here, as well as on-topic conversations in #rockbox-community, shouldn't someone set up a #rockbox-dev?
04:24:08Soapthat is what this channel is.
04:24:10safetydanTMM, it's been talked about before but in general the devs prefer to have one channel to monitor
04:25:03TMMjust a thought...
04:25:16TMM-dev is more clear perhaps, that's just it
04:26:08TMM-community should be, #rockbox, and -dev should be,well, what this is now :) but with more banning
04:26:33safetydanTMM, it's not all about dev stuff here though and it's handy to see what users are complaining about

04:54:59sdoyonI believe I have narrowed it down to one particular change. Anyone knows anything about this stuff?

04:58:00sdoyon... I mean that seemed to fix it.
04:59:15jhMikeSit's a dangerous thing to do. I think some other method needs to be employed.
04:59:24sdoyonI'd like to be more specific, but the clipping of my filenames wasn't always exactly on the same names as I tried various revs (bisecting to find the one where this started).

05:04:23Reckaseperhaps I should put something on it?
05:04:32Reckasecould it be the lack of files that confuses it?
05:05:20Reckaseit's the fact that it worked before that's getting me so frustrated

05:08:08sdoyonjhMikeS: err that'll take a recompile... hold on.
05:08:50jhMikeSThe PCM buffer is always running there, so I'd suspect all data would be played out in that case.

So those that are clipped are always clipped.

05:17:24jhMikeSThe difference for e200 vs. x5 might be explainable too. x5 uses genuine HW DMA with long transfers where as e200 does small bits with SW DMA. hmm.

05:23:01jhMikeSI imagine getting at least a couple frames in there before starting a clip may help. I think it starts playing the first frame right off. The delay would be a few ms more at most.

05:30:11jhMikeSperhaps because it forces a pcm start if it's not playing
05:31:38jhMikeSThere were some other buffer changes I had that didn't get included with that commit. I thought it was a bit out of scope to include there.

09:37:22linuxstbJdGordon: If google is correct, you have a ARM926EJ-S core. You'll need to check the gcc docs for the correct -mcpu option
09:37:45JdGordonok
09:37:48linuxstbBut you'll also need to rebuild gcc with the multilib changes I emailed the dev mailing list about - to enable building of an armv5 libgcc.a

09:42:07linuxstbIs it just me, or does mpegplayer also take longer for the initial buffering (after pressing play in the start menu) than it used to?
09:42:33amiconnIt takes quite long on PP. I blame jhMikeS's threading stuff :>
09:43:13linuxstbI remember making the initial buffer fill (before playback started) quite short, it then continues buffering in the background. Maybe that was changed.
09:43:20amiconnOn single core it's fast..
09:44:42jhMikeSwhen did that change?
09:45:04jhMikeSI know the seeking stuff made it take longer
09:45:24linuxstbI noticed it as soon as the start menu/seeking patch was committed.
09:45:58jhMikeSI think a fix to that was removing some buffer zeroing in mpeg2_alloc
09:47:33amiconnjhMikeS: Completely different thing: As I know you made the mpegplayer arm idct completely without using mul/mla, could this method also be applied to e.g. libmad's imdct?
09:47:39jhMikeSthat's what I was told anyway but I don't see any memset there
09:47:49amiconnNote that I don't know how that one looks, so...
09:48:00linuxstbNo, it's changed - the old code read MPEG_LOW_WATERMARK bytes in the initial read, the current code fills the whole buffer in the initial read...
09:48:59jhMikeSamiconn: with 32-bit constants? It's not really good for fractional fixed point and I'd say impossible or at least for anything with 64-bit intermediate values.
09:49:32amiconnhmm. What about jpeg?
09:50:12jhMikeShmmm...some values aren't large constants
09:50:13amiconnDo mpeg and jpeg use the same idct?
09:50:30jhMikeSmpeg audio uses imdct
09:50:44*amiconn could even try to write an SH1 idct using mac ...
09:50:45jhMikeSjpeg should look like mpeg video I'd imaging
09:50:49jhMikeS*imagine
09:50:56amiconnWould lower the excessive decoding time of large lpegs
09:51:21amiconn*jpegs
09:51:40jhMikeSeven large values might be decomposeable into a few shift+adds but just think of how large a set of possibilities that is to find it.
09:51:42amiconnlpeg == large jpeg ;)

10:10:56*amiconn goofed
10:11:37jhMikeSof course if something on the stack refers to the old stack, it's doa
10:12:14linuxstbjhMikeS: That's true... Probably a bad idea then. But is there any reason the codec thread should become active?
10:12:32psycho_maniaclinuxstb: did you commit the iram patch you were talking about?

10:13:41psycho_maniacalright just curious because i saw something in svn recently about iram in ipod. i guess your name is not mark. ;)
10:13:42jhMikeSthread_freeze would keep it inactive whether or not it's on the COP or same core

10:17:45psycho_maniacahhh i see. thanks for the info
10:17:53jhMikeSjust leaving slack space in case it has to run a bit before blocking on the queue I think
10:18:45linuxstbSo don't steal the whole stack, just the currently unused part, minus a little bit?
10:19:26amiconnThat might not be enough...
10:19:53jhMikeS...or devise a way to be sure it is waiting on the queue.
10:20:01linuxstbYes, I would prefer the latter...
10:20:41linuxstbCould I check the current state of the codec thread, and yield until it changes to something good?
10:21:12jhMikeShmmm...STATE_BLOCKED?
10:21:58linuxstbSo something like "while (codec_thread.state != STATE_BLOCKED) rb->yield();" ?
10:22:46safetydananyone mind a minor patch to the mpeg player to display the fps on the lcd remote if it's there?
10:22:52jhMikeSit can block other places though. hmmm.
10:23:33amiconnsafetydan: As long as it only does this when fps display is enabled...
10:23:49amiconnNotice that doing so will slow down mpegplayer slightly
10:23:58jhMikeSI guess the playback stop will wait until it sets audio_codec_loaded to false, and then it just blocks after that
10:24:01linuxstbIt could be nice to display it on the remote instead of the main LCD, if the remote is present.
10:24:02amiconn...especially if ticking reduction is enabled
10:24:59*amiconn would like that "Test mode" option instead of the 3 options that all need changing for performance tests...
10:25:18jhMikeSlinuxstb: that should work as long as it's not a COP thread. codec_thread.state could be seen as STATE_BUSY there.

10:27:17*amiconn thinks that we need a function that tells whether an *LCD* remote is connected - and that function should also be available to plugins
10:27:47amiconnRight now we only have a function that tells whether a remote is connected - whether LCD or simple
10:28:02amiconnOnly the remote LCD driver knows whether its LCD is there
10:28:51pondlifeI'd hope that individual plugins shouldn't need to care about such detail, it should be handled lower down...
10:29:03amiconn(rather, it assumes based on the remote type - there is no way to tell whether it's actually there)
10:29:42jhMikeSlinuxstb: I suppose that's ok for now. I guess any COP stuff can be dealt with at the time.
10:30:00pondlifeWhat if the user unplugs or plugs in the remote whilst something is running? Should the plugin check before each update?
10:30:04amiconnpondlife: Plugins don't necessarily _need_ to care - but they might _want_ to act different when an LCD remote is connected
10:30:26jhMikeStest_fps? as a small example.
10:30:37amiconnYou can call lcd_remote_update() anytime - that's not a problem
10:31:14jhMikeSI guess it shouldn't run remote tests is the remote wasn't plugged
10:31:19amiconnBut e.g. a game could offer a true dual player mode. It could hide that option when there is no remote lcd

10:32:35Diamond_iceman20I think the Rockbox f/w sounds better than the Apple f/w on the iPod
10:32:41jhMikeSgood thing is that you won't see STATE_BLOCKED if it still has messages to process
10:33:22amiconntest_codec should probably do the same then?
10:33:44jhMikeSI think so

11:00
11:00:12linuxstbAh, then I would be surprised if we can blame my patch for that.
11:01:15jhMikeSif one stream overtakes another, it will not properly block them but basically abort the stream
11:01:24amiconnMaybe mpegplayer doesn't handle some end-of-stream condition properly?

11:09:21ddaltonand exit the rec screen?
11:09:23jhMikeSIf it were hitting the end of data, the parser would just abort it. It might be the opposite - disk reading is dominating the video.
11:09:58amiconnIt doesn't happen if framerate limiting is on
11:10:48amiconnOr maybe it's just due to audio & video being too far off?

11:13:54amiconnelephants dream uses halfpixel motion, but no destination averaging at all
11:14:49jhMikeSit has no B-frames encoded either which help keep quality up and size down...besides the dropping advantage
11:15:30amiconnI thought using B frames makes for smaller files...
11:16:12jhMikeSor same-size files with higher quality :)
11:17:39jhMikeSlow-power devices get smoother dropping with them too since dropping P means you can't draw anything again until another I. B frames are unreferenced.
11:17:50Zagorhmm, how do I find out if I'm being called in interrupt or thread context?
11:18:24jhMikeScheck cpsr?
11:18:41Zagorthat doesn't sound terribly cross-platform?
11:19:12Zagorlet me rephrase: do we have some method for finding out the current context?
11:19:18jhMikeSI guess implement an is_interrupt_context or something. That's really the only way to know.
11:20:12Zagorok
11:21:11jhMikeSWhy do you need to know?
11:21:52Zagorwell I'm thinking about trying some delays before sending, but I assume I'm not supposed to call yield() from interrupt code?

11:45:51amiconneh?
11:46:09amiconnThey need to modify the output framebuffer(s) at some point...
11:46:21preglowsure, using interpolated motion vectors
11:46:38preglowi really don't know, i only reliably remember stuff about i and p frames
11:46:39jhMikeSddalton: excuse me, it's recording_screen
11:46:44amiconnhmm
11:46:46preglowfor some reason i consistently forget what i'v read about b frames
11:46:52ddaltonso I just write recording_screen ();
11:46:56ddalton?
11:47:10ddaltonNow ignoring pixelma -BOFHNet IRC Ignore-
11:47:16preglowbut ok, time to commit the other asm stuff so wma can be fasted on coldfire than arm :>
11:47:25jhMikeSddalton: it has a paramter to allow source changes as well: bool recording_screen(bool no_source)
11:47:46pixelmaddalton: ?
11:47:51ddaltonok thanks for that
11:47:52safetydanpreglow, linuxstb, just posted a basic resync of the hw eq patch
11:48:32jhMikeSddalton: It's used from the FM screen to hide the other sources
11:49:11ddaltonSo I give either true or false?
11:49:15preglowsafetydan: most excellent
11:49:22jhMikeSyeah.
11:49:34ddaltonso what does true do?
11:49:51jhMikeSdisables and hides the audio source selection
11:50:05ddaltonok
11:50:33jhMikeSit then needs to be set in advance before calling the screen
11:51:21ddaltonso I just can't call recording_screen (false); from my function?

11:56:11*jhMikeS thinks bool recording_screen(int source) would be better where SOURCE_DEFAULT uses the global setting and allows selection. maybe a change for later.
11:56:30safetydanhrm, now should cutoff be a choice setting or an int setting?
11:57:45ddaltonok I will try this.
11:57:48ddaltonthanks for your help
11:59:01preglowsafetydan: choice as in strings?
11:59:32preglowsafetydan: if we use pure ints, it'll be hard to say which is the higher cutoff setting for some users, perhaps
12:00
12:01:52safetydanpreglow, well strings for the user anyway, something like "lowest low high highest"
12:01:54jhMikeSddalton: I was just speculating on a nicer was to do something. The last thing I said won't work.
12:02:02preglowsafetydan: i think we decided against that
12:02:24preglowbut it's not going to be much different anyway
12:02:39safetydanpreglow, so just straight 0 to 3 (1..4) then?

12:03:06preglowsomething is weird on nano now
12:03:45preglowsometimes i get data abort/illinstr and pink spots in the wps
12:03:53jhMikeSpreglow: what did I do now? :P
12:04:29jhMikeSwasn't nano misbehaving when warm?
12:04:30preglowmight be me, but i think these asm snips are correct
12:04:40preglowjhMikeS: yeah, but mine isn't, i think
12:04:43preglowperhaps that's it, though
12:05:01jhMikeSchill it in the fridge and see
12:05:08preglowwell, it doesn't do it reliably
12:05:48jhMikeSpink spots doesn't sound like anything I've worked on would cause. You'd either crash or not.
12:05:55LloreanWell, pink spots in the WPS have never been reported as part of the warm-Nano problem
12:06:33LloreanIt pretty much restricts itself to "garbled playback" and "data aborts and illegal instructions at completely random addresses"
12:06:52*linuxstb points committers to their mailing list and asks for help
12:07:20ddaltonjhMikeS: It compiled. now the question is: "Will it work?"
12:07:20preglowthe pink spots are transparent sections, i'm quite sure
12:07:26preglowbut god knows why the colour key is ignored
12:07:44preglowlinuxstb: have you got any wma files?

12:07:55supis there any statistics on which mp3 player is most popular with rockbox?
12:08:08jhMikeSddalton: I guess that's why one tests things. :)
12:08:14ddaltonyes...
12:08:29linuxstbpreglow: A few, why?
12:08:38jhMikeSvideo, right?
12:08:55preglowlinuxstb: would be cool if you could check out if they sounds same afterwards
12:09:20linuxstbYou mean if they still sound like a bag of shit?
12:09:28preglowyeah, mainly :D
12:09:55Lloreansup: Most popular as in "The most people have bought this player" or Most popular as in "the people who already use Rockbox mostly pick this player when they need a new one"?
12:09:59preglowlinuxstb: most helpful would be checking coldfire, i guess
12:10:19preglowlinuxstb: boost ratio goes from 175% to 255% on the bangles track on coldfire since yesterday
12:10:25linuxstbpreglow: OK, I'll add it to my to-do list for this evening.
12:10:31preglowlinuxstb: sweet
12:10:37ddaltonwell. Doesn't somone have a download log on his website.
12:10:37preglowlinuxstb: realtime ratio, i mean
12:10:40ddaltonsomeone
12:10:56ddaltonwich says how many downloads each player has had.
12:11:27linuxstbddalton: Bagder mentioned some stats a while ago - the ipod video was by far the most downloaded IIRC.
12:11:42supLlorean: well, besically, what version is the most downloaded..
12:12:20ddaltonyes and I would not reccomend it.
12:12:22linuxstbsup: The ipod video is one of the worse Rockbox targets though...
12:12:30Lloreansup: iPod Video then. Apple sold so many thousands it really couldn't *not* be #1 very easily
12:12:52linuxstbs/thousands/millions/
12:12:53supreally?
12:12:56supnot the nano?
12:13:26preglowargh, oops
12:14:10pixelmaand download stats don't tell everything, people might compile their own builds or update in different intervals
12:16:01pondlifeThe stats on rockbox-themes indicate a large iPod Video presence, although this probably indicates more that iPod users want eye candy more
12:16:33ddaltonjhMikeS: I think it is working but it doesn't work yet. There is no code to write to the file.

12:17:43mrkikoIs someone using an iRiver340 with rockbox?
12:17:50mrkikoDoes it work well?
12:17:51pondlifeOr rather, changes their use.
12:17:51linuxstbAlso, the ipod video is (was?) the only hard-disk DAP easily available to run Rockbox on.
12:17:55amiconnAh, new build started...
12:18:03pondlifemrkiko: H340 works great
12:18:14jhMikeSddalton: with recording, the disk spinup time to load an encoder would need to be waited on.
12:19:02ddaltonyes but I would still probably use this feature. so not to worried if it is committed or not. But I don't see much use for the long rec button at the minute. It just goes to the rec screen. And I have pressed it by mistake and ended up there.
12:19:09ddaltonWhen resetting my settings.
12:19:28mrkikopondlife: I live in Italy but my iRiver has an US firmware evidently. If I want, can I reinstall the US firmware and have the DRM support back? I hate DRM but I was curious to know if DRM is an hardware or software chip
12:19:41ddaltonVery annoying when speakers are attached to the player. I think this should be removed from rb. But that is just my opinion.
12:19:46pondlifeNo, once removed, you have lost DRM forever AFAIK
12:19:57supso when is rockbox fr g2 nano coming out.. : ]
12:20:14pondlifeWhen you crack the encryption and port it :)
12:20:17ddaltonits not until it is done
12:20:26ddaltonand a port first needs to be started.
12:20:31ddalton(is one?)
12:20:38pondlifeNever, is the best guess
12:20:38supencryption?
12:20:45ddaltonyes

12:21:02pondlifeOr run something
12:21:07supwhat is encrypted? : ]
12:21:20jhMikeSrunning requires it be read initially :)
12:21:52mrkikoI'm also blind - is in your opinion reasonable to thrust in rockbox speaking?
12:22:11pondlifesup: The later iPods don't have any way to run proprietary code. So unless someone finds a weakness there, or Apple tell us, there is no chance of a port even starting.
12:22:16mrkikoAnd hence - I red on the manual that plugins doesn't support speech. So I will not be able to read txt files, righ?
12:22:16*sup thrusts
12:22:29jhMikeSmrkiko: I think you can offer your opinion here

12:48:02linuxstbmrkiko: If you can program, you can change Rockbox's behaviour to suit your own personal needs. Or you can apply changes (called patches) made by other people, but not incorporated in the official version.
12:49:16ddaltonsome good patches for blind people are at the link I said before. so if you can build rb from source you can apply those patches and build.
12:49:18mrkikoOh, I know. I'm able to program in C
12:49:21mrkikodiscretely well...
12:49:37mrkikoAnd I know the patches concept... I don't know those mentioned by ddalton
12:49:42ddaltonSo for example if you applied his talking playlist viewer patch you could then use the playlist viewer with speech.
12:49:52ddaltonthis isn't possible in the normal version of rb
12:50:00mrkikoah...
12:50:03mrkikogood! :)
12:50:30mrkikoWhat parts of rockbox are accessible without patches? (i.e.: the fm radio tuner is accessible? )
12:50:43ddaltonwell sort of...
12:51:06ddaltonit doesn't voice the freq, but it voices menus and stuff.
12:52:02ddaltonmrkiko: well these just give you improvements lots is accessible. But lots isn't. Also you can other patches. Like maybe one that changes the playback or something.
12:52:08ddaltonuse lots
12:52:30ddaltonAlso I have written a couple but not sure if you will be interested.

13:02:41JdGordonlol pondlife
13:02:58Nico_Ppondlife: can you still repro the segfault on UP + SELECT in the sim ? and the others ?
13:03:17jhMikeSsince "-itis" refers to "swelling-of"...I'd hope it's the opposite
13:04:32jhMikeSNico_P: Was it really nasty to resync?
13:05:09Nico_PjhMikeS: a little harder than usual, especially as I had to edit commits back in history so that they would all compile
13:05:31Nico_P(to make bisecting possible)

13:06:21pondlifeI'm not convinced that was the right fix still though
13:06:42pondlifeI still get stalled playback if I repeat UP+SELECT enough though

13:06:54jhMikeSsorry for that. I wanted to get the disrupting over with.
13:07:09Nico_PI've noticed that too, but at least you can recover by simply restarting playback
13:07:21pondlifeBasically, why do an unbuffer callback for a track that was never buffered?
13:07:41pondlifeIt shouldn't even have been considering that..
13:07:55*ddalton Wrote his first patch that chrashed rockbox
13:08:12*pondlife has lots of those in his cupboard
13:08:18Nico_Ppondlife: I agree but I think the difference is mainly in how track_widx and track_ridx are used
13:08:48*ddalton was to do with recording :-)
13:09:18pondlifeNico_P: I was hoping the circular use of those could be scrapped some day... hint.
13:09:20Nico_PjhMikeS: also you have to know that some additions in playback.c are #if 0 and #endif around big blocks of code ;)
13:09:32Nico_Ppondlife: how ?
13:09:33pondlifei.e. let the callbacks be dealt with by buffering.c
13:10:17Nico_Ppondlife: callbacks in buffering.c is a good idea but I don't see how it changes anything for track_?idx

13:17:28Nico_PI don't know, what's HZ ?
13:18:07ddaltondoesn't matter so how do I format it in to hours/minutes/seconds?
13:18:27ddaltonI think you use "HZ" to get one second for example would be HZ*1
13:18:49peturthe tick is 10ms, HZ = 100 so HZ ticks gives 1 second

14:24:17pondlifeI too would like to have the option of using the mouse though!
14:25:16pondlifeJdGordon: How will the touchscreen/mouse support handle going back/cancelling etc. An on-screen button I suppose?

14:28:07Lloreanlinuxstb: Yeah, I would've asked about Bootloader USB, as well as rebooting the computer.
14:28:27LloreanIt could be that the automount function decided to give up after his OF test and before his Rockbox test

14:49:37JdGordoncoz they are hypocrites!
14:49:46roolkuBagder: the "annoying 'Saving settings' splash" has its purpose: It is the only feedback that the button press has registered (delay while disk is spinning up). If you are standing in the freezing rain and want to quickly move on to the next textfile this is quite important
14:49:48markunGodEater_: I saw that project gutenberg is now starting to use speex for audiobooks: http://www.gutenberg.org/etext/19683

14:50:23JdGordonBagder is in china atm iirc

14:51:39Zagorsorry, didn't see the above line.
14:51:53ZagorI think such feedback would be better achieved by simply clearing the screen or some such.
14:52:13ZagorI found the splash exteremely annoying
14:52:17amiconnlinuxstb: Do you have plans to do optimisation work on libdemac?
14:52:54*jhMikeS threw a "Saving Settings" splash in jpeg.c but only when they change. It help distinguish it from a lockup.
14:53:06amiconnThere is quite some potential for speedup especially on coldfire
14:53:08roolkuwell, looking at a blank screen strikes me as less usefull than seeing the text with a splash on top
14:53:22linuxstbamiconn: Not for Coldfire - I don't know it. But yes, I would like to spend some more time on ARM at some point.
14:53:24roolku-l
14:53:44Zagorroolku: sure, but the point is normally that splash i shown for a mere fraction of a second and just becomes "UI noise"
14:53:45amiconnThe scalarproduct() would fly when using emac
14:53:47markunamiconn: would be great if you could at least get some compression level realtime
14:54:08amiconnAnd the additions and subractions could at least profit from burst reads & writes
14:54:25amiconnAre these buffers in iram or dram?
14:54:51linuxstbAs much is in IRAM as I could put there - I spent some time optimising iram usage for Coldfire.
14:54:52Nico_Proolku: the splash should probably be shown only when the settings actually need saving
14:55:09linuxstbamiconn: Which buffers specifically?
14:55:36amiconnThose on which scalarprodcut() and vector_add() / vector_sub() are used upon
14:55:41roolkuNico_P: they are always saved on exit, unless I overlooked something
14:55:48Nico_PGodEater_: I've just used SVN on my gigabeat for a bit and I don't find it any faster to skip to an unbuffered file when the disk isn't spinning

14:57:09Nico_Proolku: ah, right. I didn't realise this was part of the settings too
14:57:27linuxstbamiconn: Yes, they are.
14:57:58amiconnEven for the largest filer size?

14:59:13linuxstbamiconn: But the buffers for compression level up to and including -c4000 are in IRAM. Only -c5000 (aka insane) uses that 1280 order buffer, which isn't in IRAM.

15:08:33JdGordonwell this sucks!
15:08:36amiconnHehe, I prefer paged scrolling because line scrolling is too slow. Actually you can always do both
15:08:38roolkuNico_P: but your approach would only work for fixed-width fonts?
15:08:50amiconnAnd a column is undefined for proportional fonts
15:09:32amiconnYou could of course use some approximate width as "column", e.g. the width of 'A' (as used in several places)
15:09:35linuxstbamiconn: Yes, there's potential in lots of places...
15:09:47Nico_Phmm true. but maybe scroll by a smaller amount them

15:10:50linuxstbNo, I think the predictors are 32-bit, and filters 16-bit (or vice-versa)

15:26:27Lloreannerochiaro: Pretty much every known attempt has a thread in the New Ports forum as an attempt to call attention to other interested parties
15:26:48nerochiaroi'll check that
15:26:50nerochiarothanks
15:27:16JdGordonjhMikeS: well, im not actually sure if the irq isnt triggering... i only get the BUTTON_TOUCHPAD once, and i tihnk ive found everywhere it could be filtered out, so im confused
15:28:17jhMikeSput a counter in the handler and splash it somewhere or show it the debug menu somewhere?
15:28:32linuxstbnerochiaro: There are people working on porting Rockbox to the m:robe, which has the same CPU as the Zen - that will make a Zen port easier, but still needs interested and skilled people to do it.
15:29:31nerochiarolinuxstb: the zen V ? i see something about the zen vision M, but not the V
15:30:29linuxstbnerochiaro: I just assumed they all used the same CPU. I could very well be wrong though...

16:30:47Nico_Ppondlife: btw, thanks for your test album, it's very useful for testing and funny too
16:30:56pondlifeIndeed
16:31:50Nico_Pwith the latest commit, you can have ~30 tracks in the buffer and skip back and forth within these without having the disk spin at all
16:31:55 Quit MethoS- (Remote closed the connection)
16:32:17pondlifeCool, so you only unbuffer when you need the room?
16:32:22Nico_Pexactly
16:32:33pondlifeThat's how it should be
16:33:02pondlifep.s. I never did see the buffering debug screen...
16:33:07pondlifeAm building now.
16:33:29pondlifemake install
16:33:30LloreanNico_P: Does this also mean that if you set put, say, 3 tracks in a playlist and they all fit in the buffer, "Repeat" won't result in rebuffers?
16:33:32pondlifeOops
16:33:52LloreanAssuming, that is, the playlist isn't reshuffled?
16:34:04pondlifeLlorean: It should do... a bug if not I reckon :p
16:34:15Lloreanpondlife: Well, it's a long, long standing bug right now, I believe.
16:34:24pondlifeIndeed
16:34:44Nico_PLlorean: good question, but I think it will rebuffer. That's probably because of the playlist code though. I'll test to make sure
16:34:46LloreanSo if it doesn't, it's not a new bug, just not a fix for the old one.
16:35:12pondlifeOr a bug in the new code if it's intended not to rebuffer in this case...
16:35:24Lloreanpondlife: Well, it's more a playback code issue, I'd imagine.
16:35:31pondlifeI think the old behaviour was more by design than a bug
16:35:41mrkikoIs there a completely hardware-opened mp3 player where rockbox can be used?

16:35:53peturNico_P: there's also an issue where multiple times the same song causes the same file to be buffered again and again... will your system also handle that?
16:35:54Lloreanpondlife: I think the old behaviour was more because the original buffer often wouldn't hold even one song.
16:35:56Nico_PI think when repeat is set, the playlist code makes the playback code believe it's like an infinit playlist
16:36:21pondlifeLlorean: Indeed, the design was the same since Archos Player.
16:36:33LloreanNico_P: Would it at all be possible to have it detect if a song in the playlist is already buffered, and go to that?
16:36:37Nico_Ppetur: ATM it doesn't but it could
16:36:58LloreanNico_P: For example if my playlist is song A, B, A, C A, instead of buffering A three times, somehow handle that case? (It seems like that'd also fix rebufering with repeat, even with shuffle)
16:37:15*petur discovers he asked about the same thing Llorean did :/
16:37:17Nico_PLlorean: I think so, as the filename is stored in the handles, so bufopen could return the id of an existing handles in case of duplicates
16:37:57JdGordonexcept you have to make sure you dont trash the handle untill everything using it is done
16:37:58Nico_Pthe only problem in that case is that I'd need to be very careful before bufclosing
16:38:14Nico_PJdGordon: we agree :)
16:38:14LloreanWell, just something to keep in mind at least. :)
16:38:37*JdGordon not sure its worth the overhead
16:38:50Nico_Pthe case i had in mind for that is album art... we don't want to buffer ten times the same bitmap
16:39:14LloreanJdGordon: For short playlists (or long playlists of very short files) it could drastically reduce disk spinups.
16:39:29*Llorean is curious how long his gigabeat would last on RAM-only playback.
16:40:06Nico_PLlorean: the main buffer is roughly 30 MB so you do the math according to your avg bitrate :)
16:41:25LloreanNico_P: If you take a 30 megabyte segment of my playlist the average bitrate could be as low as 100bps or as high as 990kbps or so.

16:42:18LloreanActually it's probably closer to maybe 500bps
16:42:21pondlifeNico_P: I found your debug screen...
16:42:32pondlifeWhat's the "useful" figure mean?
16:42:33Nico_Ppondlife: was it that hard to find ?
16:42:37pondlifeNo :)
16:43:00Nico_Ppondlife: basically it's the data that hasn't been played yet
16:43:38Nico_PI know the labels can be a bit confusing if you're not familiar with the code
16:43:51pondlifeHmm, so you consider data as useful still even though it could be skipped back into?
16:43:55pondlifeOr rewound into
16:44:06Nico_Phmm I have a one track long playlist and the track is buffered 4 times
16:44:31JdGordonthat makes sense though
16:44:52mrkikoIn my opinion the solution to have rockbox on the hard drive and not on the flash is very very intelligent
16:44:52Nico_Ppondlife: no. useful data is the data between the current read position and the write position
16:44:59JdGordonNico_P: if you really want to add handle sharing, you should only do it for repeat playlists.. not for when 1 track is in the playlist multiple times
16:45:11pondlifeWhy do my 7 buffered tracks have 14 handles? Not all codecs, surely?
16:45:23Nico_PJdGordon: that distinction doesn't apply in buffering.c
16:45:35Nico_Ppondlife: each track has metadata and audio
16:45:38pondlifeAh, ok
16:45:42pondlifePhew
16:45:52pondlifeI imagined lots of buffered MP3 codecs
16:45:54JdGordonNico_P: hmm, ok

16:47:21Crash91is there any specific reson why rockbox cant support 32x32 icons?
16:47:56LloreanCrash91: I don't think there are any fonts 32 tall, even.
16:48:04Crash91ter32?
16:48:30LloreanDoes it just not load the images?
16:48:48Nico_PJdGordon: maybe to handle multiple bufopens for the same file I could add a counter in the handle struct ? so that it has to be bufclosed the same number of times before it actually disappears
16:48:53Crash91i havent tried yet, im thinking of making one, but it says its limited to 24x24
16:49:17LloreanCrash91: My guess is it was probably decided that icons that large would take up too much screen space. We have to pre-allocate memory for them, so a limit had to be set somewhere.
16:49:28Nico_Ponly problem with that is I can't detect multiple identical bufallocs with metadata
16:49:32Crash91kk =) 24px it is
16:50:07Crash91btw...on the sansa...what if the disk is full, where does rockbox store its memory?
16:50:14Crash91in the FW partition?
16:50:30LloreanCrash91: I don't understand the question, at all.
16:50:45JdGordonNico_P: I woudltn worry about it untill mob is working fully anyway
16:50:48Crash91well rockbox has some stuff on disk, like RAM right?
16:50:53LloreanCrash91: If the disk is full and Rockbox needs disk space, there will be errors. But "memory" refers to RAM, not disk space.
16:50:53pondlifeNico_P: Nice work
16:51:05Nico_PJdGordon: yeah, my current goal is "no regressions"
16:51:11Crash91k
16:51:45LloreanJdGordon: I just brought it up so that the idea can be there, so he doesn't accidentally code it into impossibility if it isn't already. :)
16:51:50Nico_PI'm thinking I can commit when there aren't any major regressions left and improve after that
16:52:22pondlifeOnly slight problem is that skipping backwards repeatedly, results in another rebuffering. But that's fair enough, our main aim is playing forwards!
16:52:44Nico_PLlorean: *if* it's impossible, it's because of the current code. hopefully the new buffering code is flexible enough to handle it correctly
16:53:08Nico_Ppondlife: yes, but you can't predict how far the user is going to skip backwards :)
16:53:19LloreanNico_P: Hopefully. :)

17:13:19Nico_Pit shouldn't have changed recently in MoB
17:13:29pondlifeEarly ones seemed slower in MoB, but I thought that improved
17:13:47pondlifeShould be possible to knock up a timer to prove it, right?
17:13:58pondlifeDo we have a system tick counter?
17:15:16Nico_PI think so
17:15:26pondlifeOne thing which I think is new to MoB... my WPS has a playlist index displayed (9 of 2300) or whatever...
17:15:58 Quit MethoS- (Remote closed the connection)
17:15:59Nico_PI see nothing wrong with that
17:16:02pondlifeI thought the number (9) used to increase immediately when I skipped. Now it's rather slow
17:16:21Nico_Pah yes it has a small delay compared to the rest of the metadata
17:16:24pondlifeI mean when skipping during buffering
17:16:31pondlifeOooh
17:16:43pondlifeI've just got the wrong track displayed
17:16:58pondlifePlaying Spiritualized, but displaying Elvis Costello..
17:17:22pondlifePlaying track 15, but displaying track 16
17:17:26Nico_Phow did you manage that ?
17:17:35pondlifeJust skipping forward during buffering
17:18:04pondlifeForward repeatedly fast
17:19:03pondlifeCan't repro it yet though
17:19:45pondlifeRemember I crossfade everything too, in case that's relevant.
17:21:40Nico_Ppondlife: about the (x of y) playlist indicator, I'm pretty sure MoB is an improvement over SVN. In SVN, when you skip to an unbuffered track (say, from 14 to 15), the playlist pos would stay on 14 while the rest of the WPS shows the filename of track 15 (because metadata isn't ready), and then the playlist indicator moves to 15 when the metadata arrives
17:22:12Nico_Pin MoB, metadata is displayed immediately when you skip
17:23:03pondlifeI'll need to compare again..
17:23:20pondlifeI recall that the x of y part was quick though
17:23:41pondlifeSo I could get to a track quite quickly before waiting for buffering
17:24:41 Quit JdGordon (Remote closed the connection)
17:25:04Nico_Pah, comparing I see that in mob the playlist position isn't always updated. there are some skips, like 9->12->15

18:20:20moosthe only case you will have rebuffering for track B in our exemple, that's if you made the disc to spin for browsing for exemple, cause the buffer is refiled at nay disc activity

18:24:01moosNico_P: currently it *doesn't* rebuffer if the track is in totality in the buffer
18:24:28Nico_Pyeah that's what I just saw... I must've been confused
18:24:28 Join Jon-Kha [0] (n=Jon-Kha@80-248-247-190.cust.suomicom.fi)
18:24:38moosyou will have refilling for the first or the last filed files
18:25:01Nico_Pwhat do you mean ?
18:25:20moostake my simply exemple
18:25:45moos3 tracks buffered
18:25:50moosA,B,C
18:26:11moosyou will not have rebuffering for the track B only
18:26:31Nico_Pwhy ?
18:26:45moosbecause the first one isn't 100% filled and the last one too
18:27:04Nico_Phmm than I believe my code is an improvement
18:27:31 Quit obo ("bye")
18:27:36mooslet's hope then :)
18:27:49Nico_Phave you tried it or had a look at it ?
18:28:48moosbut this buffering thing for skiping back is more "problematic" for targets with less availiable memory
18:29:33moosfor exemple on my X5, 12mo and something isn't big, then I have big chance to have rebuffering for a skip back
18:30:15amiconnlinuxstb: Looks like test_codec freezes the target if it's waiting for the final button press (which btw. is illogical) and the poweroff timeout kicks in
18:31:09moosbut on my gigabeat with almost 30 mon, that's better cause betwen the first and the last buffered tracks, there are few 100% buffered tracks that will not need disc for skip back
18:32:00moosNico_P: I didn't find the time for test your new code yet
18:32:45moosNico_P: pm for french, that's better :)

21:52:51amiconnWe're alreadycompiling with -ffreestanding
21:53:11rasherprzemhb: put MEM_FUNCTION_WRAPPERS(rb) somewhere at the top of your plugin - not within any function, and the rb pointer must be global
21:53:19amiconnThe target environment must provide the 4 basic mem* functions
21:53:21Domonokyprzemhb: just add the macor rasher mentioned, to your code, and it will work.. :-)
21:53:33amiconnAh, yes
21:53:45amiconnDidn't remember we have a macro for that nowadays...

21:56:07rasherBut not the background? Sounds "dangerous"..

22:00:11rasherI understand the point about making it more visible, but it also looks really strange with the gray in the middle of it all.
22:00:38kkurbjun_I did try registering that seperate
22:00:47kkurbjun_it didn't seem to work too well
22:00:48eigmabutton_read/button_read_device() non-blockingly reads the uart hardware fifo (which can be configured up to 32 bytes long) and sees if there's any heartbeat responses
22:00:56eigmaif so, it parses them and returns the key status
22:01:04 Join davina [0] (n=davina@cpc1-sout6-0-0-cust616.sotn.cable.ntl.com)
22:01:04eigmaand then it purges the fifo
22:01:14eigmaand does not send any heartbeat
22:01:37kkurbjun_so right now that's close to what I am doing in the latest code
22:01:37eigmacan you explain what didn't work?
22:01:49kkurbjun_it's working well at the moment
22:02:21kkurbjun_but I was thinking about how to add in screen updates in a generic fashion without blocking
22:02:45kkurbjun_since we only have a 32 byte fifo, it's not nearly enough to fit the whole screen
22:03:04eigmaokay, then introduce an irq-driven TX queue
22:03:23eigmabutton_read_device() and remote_screen_draw() just queues packets to that queue
22:04:04kkurbjun_and remote_screen_draw would be a tick task also?
22:04:06eigmait could be a circular buffer large enough to fit the largest burst of screen updates we'll ever have.. my gut tells me 1K is plenty
22:04:09eigmano
22:04:13eigmaremote_screen_draw is just called whenever
22:05:13eigmatick -> remote_heartbeat_tick() -> uart_queue_tx_bytes()
22:05:28eigma(time of day changed) -> remote_screen_draw() -> uart_queue_tx_bytes()
22:05:37amiconnlinuxstb: ping
22:05:42eigmaUART TX Int -> uart_queue_tx_drain()
22:05:57kkurbjun_I see, what would the arguements be to the uart driver for uart_queue_tx_bytes?
22:06:09amiconnrasher: Do you have a better suggestion?
22:06:16eigmaconst char *buffer, size_t bytes??
22:06:41eigmaI get the feeling that was a trick question :)
22:06:56rasheramiconn: Not sure I do, no - perhaps a "shadow" in light-gray at the right-bottom?
22:06:56kkurbjun_:), somewhat
22:07:02eigmawhat was your point?
22:07:14amiconnrasher: That would make them look "hollow"

22:07:30kkurbjun_well, I'm thinking for multiple commmands to be sent
22:07:36rasheramiconn: hrm... I'll think about it
22:07:42amiconnAlso, the plain grey background improves readability when a background image is loaded
22:08:06kkurbjun_and I guess we could just copy the data to the ring buffer though
22:08:12amiconnIt doesn't have to be grey, it could be configurable
22:08:30rasheramiconn: well I wouldn't want to use the background image for splash background ever
22:08:40rasherI agree that it should be a plain colour
22:08:54rasherperhaps it should be just another theme setting
22:09:17amiconnThe grey was introduced when we got greyscale display on the H1x0. The splashes looked a bit dull with the same white background as the rest of the screen
22:09:43kkurbjun_eigma: I think I am seeing how you are envisioning this, so we would effectively have two copies fo the remote screen buffer in memory, one in the ring buffer, and one for the rest of rockbox to draw to?
22:10:37 Join uki [0] (i=uki@ip-195-140-236-39.unreg.tvk.wroc.pl)
22:10:51eigmathere would only be two copies for the (short) amount of time between the draw packet being queued and it going out on the UART
22:10:58mrkikoehehehalskfjsdakljflasdkfj
22:11:01mrkikoI'm on rockbox!
22:11:13eigmaI see your point now; we could have a periodic tick handler that updates the screen straight out of the framebuffe
22:11:19mrkikowowowo! It doesn't speak again, even if I put english.voice in .rockbox/langs
22:11:20ukihi, im here for the first time because i got a question
22:11:54kkurbjun_that could work also, but I think I like your solution better
22:11:57ukiare you going to create roxkbox for iriver clix? is it possible
22:11:58uki?
22:12:05kkurbjun_a bit more memory, but simpler overall
22:12:25eigmaI think 2 KB vs 1 KB is negligible

22:12:31BigBambiuki: If someone with the clix has the skills to do it it will happen. Ports are made by those who want them
22:12:43eigmaespecially since there's no potential for this to multiply 100x over
22:13:07BigBambiuki: The RockBox 'team' doesn't decide to do a port, interested owners do.
22:13:27ukie..im interested bu my skills...
22:13:32uki:(
22:13:52ukibut thanks for the answer
22:13:56eigmakkurbjun: I think it's also more flexible when it comes to turning the BL on/off.. the respective event handlers will just have to queue a command somewhere and forget about it.

23:05:29mrkikobut ehehe
23:05:36mrkikothe manual says to press play to save the changes
23:05:42mrkikobut the player simply ignores it
23:06:09mrkikoIs it possible rockbox has crashed?
23:06:16mrkikoand, if this happen, what should I do?

23:07:31mrkikoeveneven a sighted user can't make the player react

23:08:24BigBambiAt this point, I'm going to suggest pressing all the buttons to see what happens :)
23:08:41mrkikook
23:08:57mrkikoactually nothing :)
23:09:37BigBambiSo none of them do anything? For instance does up down left and right move the cursor around the virtual keyboard?
23:09:37mrkikoI guess aniway the hardware engine (fm radio) would still go ahead for ours now...
23:09:53BigBambimrkiko: I don't understand
23:09:54mrkikono
23:10:04mrkikomy sister sais the cursor is not visible
23:10:21BigBambiIf no buttons do anything at all, it may indeed have crashed. What player again?
23:10:30linuxstbA long press of the "on" key should quit the keyboard on the h300.
23:11:07mrkikoh340
23:11:22mrkikono, the on key does nothing: I kept it pressed for 30 secs
23:11:55mrkikoAniway: even if it's crashed it would be nice to be able to power the playert off
23:11:58mrkiko:)
23:12:02linuxstbThen it seems it's crashed. You'll need to press the reset button. I don't know where it is on the h340...
23:12:07BigBambiIf it really has crashed (although the H300 port is pretty stable), I think the H300 has a reset button on the bottom (although I don't own one myself)
23:12:23BigBambiI thin it is a little hole on the bottom where the power input is
23:12:29BigBambi*think
23:12:39linuxstbOn the h140 you need something like a paper-clip to press it.

23:18:31BigBambirasher: I just searched the entire pdf manual for reset and din't find anything relevent
23:18:35mrkikoI looked at the voice mpeg sequence structure. I guess the mp3 reader skips at the right offset when it needs to say something, right?
23:19:12mrkikoWen I kept pressed the right key for a while, probably I made rockbox go mad searching for the right offset of the letter to say...
23:19:20mrkikoAm I explaining myself?
23:20:04BigBambiYes, but I don't use voicing so I have no idea how well or otherwise various parts of it work

23:44:09rasherWow, where on earth do you even find gcc 2.95 this day and age
23:44:15Zagorkeanu: I've hit a snag. the first bulk transmit works great, but the second becomes all-zero and the rest are ... strange
23:44:41preglowmoos: here?
23:44:48Zagorrasher: I think there once was a m68k cross-compiler package in debian. I guess that's what he dug up.
23:44:50keanuZagor, ok, good luck on getting it working
23:45:27bertrikZagor, maybe first you should get the base USB transfers rock solid before trying to pile the MSC stack on top
23:45:38moospreglow: hello
23:45:45Zagorbertrik: base=setup/control ?
23:45:50preglowmoos: did you even find out what was wrong with your musepack?
23:45:52Zagorthey are already solid
23:46:11Zagormsc is simply the first test case for bulk transfers
23:46:18bertrikI mean, write a simple USB bulk echo or something like that
23:46:47bertrikusing libusb on the hostside
23:47:22Zagoryeah maybe. but msc is very simple so it's not like it's adding a lot of complexity anyway.
23:48:05moospreglow: nope, I fall to stop my musepack uses on my gigabeat. I tested again with all dsp stuff off, but nothing
23:48:08bertrikBOT is more complex than it seems, mostly because of all the different cases where host and device disagree on the direction/amount of data to be transferred
23:48:32preglowmoos: have you tried test_codec and wav writing?
23:48:48Zagorbertrik: ah, the famous 13 cases :)
23:49:00bluebrotherZagor: thanks.

23:49:35Zagorbertrik: your point is very valid. I'll do that.
23:49:43moospreglow: I didn't, but I probably will, cause that's very strange that no one had never complain about. Mybe defected chip. Who knows...
23:50:04preglowmoos: i doubt it, but we already have gigabeat trouble with vorbis
23:50:06przemhbbye
23:50:12preglowmoos: a test_codec run with wav writing would be very helpful
23:50:14 Part przemhb
23:50:24moospreglow: I'll try this week-end and let you know the results
23:50:24preglowmoos: do all files sound shit, or just some?

23:50:46moosall unfortunatly, all that I tested at least
23:50:49preglowok
23:50:58preglowany gigabeat f people here that can be bothered to do some testing?
23:51:11bertrikgood luck!
23:51:19 Quit bertrik ("bye")
23:51:26moosIIRC Nico_P tested with no troubles
23:51:27krazykitpreglow, sure
23:51:41preglowkrazykit: do you have test_codec plugin?
23:52:02Nico_PI sent some parts of the WAV output to buschel and he found them to be fine
23:52:18preglowkrazykit: you pretty much only do if you make your own builds and enabled it
23:52:27krazykitpreglow, no, but i can enable it if you tell me how ;-)
23:52:36krazykiti have build environment sitting right here
23:52:40moosthat's maybe my gigabeat that sucks ???
23:52:42preglowkrazykit: just put "test_codec.c" in plugins/SOURCES
23:52:49preglowmoos: i'm about to find out

23:53:28preglowmoos: but you have tried other codecs, right, and they sound good?
23:54:07moosyup, I encountered probles just with my mpc files, and since the changes I pointed to you
23:54:24toffe82moos: yes :)
23:54:46mooshey toffe82 :)
23:54:46markunpreglow: what kind of trouble is there with vorbis on the gigabeat?
23:54:59markunhi moos :)
23:55:03moossalut
23:55:13toffe82moos: long time no see
23:55:13preglowmarkun: the latest tomal optimizations seem to bug out on gigabeat, don't they?
23:55:17preglowmarkun: something in imdct
23:55:43toffe82moos: you put a new hd on your gigabeat ?
23:55:53markunmaybe my build is too old, but I pretty much use vorbis exclusively and didn't notice anything

23:57:06krazykitpreglow, hold on, i got a build error. i'm supposed to add the test_codec.c to apps/plugins/SOURCES?
23:57:08preglowthat patch was closed, then reopened because of gigabeat trouble, afaik
23:57:13preglowkrazykit: myeap
23:57:27krazykitoh bugger, i typo'd it
23:57:33preglowexplains that, then :P
23:57:39pixelmaIIRC tomal's changes were excluded from the gigabeat or something like that
23:57:52*preglow has too few targets :/
23:57:57markunpreglow: ah, it's the code I turned off instead of fixing I think :)
23:58:06preglowmarkun: i do believe so, yeah :P
23:58:12preglowmarkun: do you remember the symptoms?
23:58:23preglowi would very much like to see that resolved in a better way

23:58:35preglowit'll just rot in the tracker if not
23:58:46markunthe problem was that the gigabeat doesn't have .icode so we should use .text
23:58:58preglowwas that the entire problem?
