00:24:00amiconnSo you can actually free 2 registers
00:25:52amiconnThat'd be easier in an external .S file as a helper function...

00:33:26mirakI am surprised of the number of fps reached even with the sound.
00:33:28amiconnmirak: Yeah, it got some asm love since...
00:33:31Buschelamiconn: then please also test to switch off the 14ms delay (the whole "if finishup_needed"-sequence) and give it a try. works fine during video playback
00:33:47mirakamiconn: I guess not only idct was put in asm
00:34:01amiconnNo, also some variants of the motion compensation
00:34:06mirakamiconn: idct.c I mean. are quantization parts optimised ?
00:34:11amiconn(the same which are asm'ized for arm too)
00:34:14 Quit Buschel ()
00:35:16mirakamiconn: hum do you think that with wav sound instead of mp3 it could play 25fps without a problem ?
00:35:37preglowaudio is decoded by the second core
00:35:38mirakI would be interested by this possibility
00:35:52mirakpreglow: a second coldfire core ? :-D
00:35:52amiconnI will try to squeeze the y interpolation motion compensation stuff into asm too
00:35:57preglowmirak: right
00:36:11mirakpreglow: ??
00:36:19preglowthen you will get better fps, yes
00:36:20 Part S1gn
00:36:38amiconnMight be tricky, as I will hit the d register limit - and a registers can't do all the neat things...
00:37:27mirakamiconn: mike something suggested that in idct it could be possible to optimise the byte overflow thing
00:37:36amiconnI also think that there might be some buffers hiding which should be moved into iram
00:38:31mirakamiconn: I looked at asm code for idct but don't remember exactly everything. did you used the double buffer for the 8x8 64 byte pixel block ?
00:38:58amiconnWithout that, the reload would be a pita
00:39:31mirakyep. I did some weird thing also, to be able to store the bytes in reverse order
00:39:32amiconnJust compare your patch with svn :)
00:40:02mirakyes I should. I am happy you finally worked on it :D
00:40:09amiconnI found why your try at an .S file didn't work, and I also applied byte packing to the _add variant of the idct
00:40:51mirakthe .S file was not of me, I didn't had enough knowledge to do that. Maybe you should credit the guy that put the inline into the file, I don't know
00:40:52amiconnThere are some clever tricks hiding, involving swap, shifts and temp registers...
00:41:18mirakamiconn: that you added or that I did ?
00:41:35mirakI remember I did that though, but wasn't exactly sure if it was the good way to do it
00:42:52amiconnI also shaved off 2 instructions from the second mac.w block of each loop, utilizing the fact that there are 2 pairs of macs where 2 terms are identical
00:43:17amiconn(using move.l %accM, %accN to duplicate)
00:44:50mirak(MikeS) - Tuesday, 18 September 2007, 00:04 GMT
00:44:50mirakOk, somehow I've gotten into doing this for ARM. Will probably stick with the butterfly form there but initial results with changing the simpler routines looks promising.
00:44:50mirakThere's much room for improvement in this patch since Coldfire can more efficiently 1) use emac multiplication to clamp outputs than it can use shifting. Better yet, 2) scale the emac routines to saturate themselves with no clamping stage by making all output left-justified. Coldfire core DSP uses 1), SPC codec uses 1) and 2). Another word of advice: avoid msac - it's dog slow - and mac the negative product.
00:45:15amiconnI know - and that won't work here
00:45:28mirakah too bad.
00:46:03mirakthis part is a bit furstrating, because it's like there could be an easy optimisation because it's just a poor byte, but in fact no.
00:46:10amiconn..since you need to clamp the final output *after* adding/subtracting the 2 halves of each direction
00:46:37amiconn...but we don't have 8 accumulators, there are just 4
00:46:44mirakamiconn: have you tried implementing the optimised C version ?
00:47:30mirakthe on with 7 mult and 8 adds or something like that.
00:47:42mirakand butterflys
00:48:14mirakIt's not very well suited for EMAC but I am wondering

00:50:04amiconnOh, from where? :)
00:50:08 Quit DogBoy ("Leaving")
00:50:16amiconnmirak: No I didn't
00:50:24mirakamiconn: I was also wondering if at some places, the algorithms works directly on ram, and if it would not be better to try to copy to Iram the subsets of data used, then work on them, and copy back the buffer to ram
00:50:30 Quit ender` (" Sex is dirty - if you do it right. -- Isaac Asimov")
00:50:52n1spixelma: could you test if that midi that gave you a data abort is fixed now with latest svn?
00:50:54mirakfor motion compensation this happens. it works on blocks of 32x32 pixels I think
00:50:56safetydanpreglow, speex?
00:50:56Mouser_Xpreglow: That sounds wrong...
00:51:21preglowsafetydan: yep
00:51:51preglowsafetydan: the decoder states are really small, i get both narrowband and wideband states in iram, no trouble at all
00:51:52safetydanah at last speex is getting some love
00:52:02preglowsafetydan: yeah, i have some assembler lined up too
00:52:14mirakamiconn: from what I remember the only place where there was an alternate buffer was for the idct block. But maybe it could be done for some other stages
00:52:36amiconnmirak: Motion compensation now loads longwords at once instead of bytes
00:52:47pixelman1s: will do in a moment
00:52:53preglowit's a bitch that speex uses 16 bit arrays internally, though, that means dsp has to convert, but again, that's a reason for speex states being so small
00:53:03amiconn(well, the asm optimized variants, which are plain copying and x averaging copying)
00:53:05n1spixelma: thanks
00:53:44 Quit spiorf (Remote closed the connection)
00:54:06amiconnIn fact the asm motion compensation functions load data using movem, so those working on 16x16 blocks might be luckky and even see a line burst occasionally
00:54:10mirakpreglow: would it be hard to allow mpegplayer to use another audio codec ? like wav wavpack or something that really don't use a lot of ressources
00:54:29amiconnwavpack is more demanding than mpeg audio on coldfire
00:54:40markunI believe ac3 is not so demanding
00:54:45amiconnlibmad on coldfire is very efficient
00:54:59mirakmarkun: gigabeat fares well on the benchs
00:55:24amiconnI think the only compressing codecs with are faster are flac and shorten
00:55:52mirakamiconn: do you have an idea what is the repartition of % cpu usage between libmpeg2 and libmad during playback ?
00:56:04amiconnBut as long as we use mpeg streams we're bound to use mpeg audio - and imho using something else doesn't make much sense
00:56:06preglowmirak: don't know, linuxstb did that
00:56:16preglowbut really, though
00:56:21mirakpreglow: yes right sorry
00:56:25preglowwe should just optimize mpeg audio further in any case
00:56:32preglowit's already pretty fast
00:57:07 Quit Arathis ("Bye, bye")
00:57:12Nico_Ppreglow: I was toying with the spectrum analyser plugin idea yesterday and had a look at a bit of code... does pcm_play_dma_get_peak_buffer provide the required data ?
00:57:24preglowNico_P: no idea
00:57:26mirakamiconn: well wav allows the 25fps on iriver. But that would huge files ...
00:57:44Nico_Ppreglow: do you know how much data is required ?
00:57:57amiconnI'd rather like to see multiple sample rate support in mpegplayer
00:58:14amiconnThen we could use 22kHz audio for less audio decoding demand
00:58:52mirakgood sound is what makes you enter in the video since image is small
00:59:03 Nick _pill is now known as pill (
00:59:08preglowNico_P: depends how you're going to get the spectrum data, if you're using filters: everything from 1 sample and up.if you're using ffts, it depends on fft block length, usually around 512 or 1024
00:59:25mirakgood night all
00:59:35Nico_Pbytes? how much is asample?
01:00:03preglowi love the fact that speex does dynamic allocation of data on the stack as much as it can
01:01:12preglowfrom the map file, it looks like current speex only consumes 15kb of iram :P
01:01:19preglownice little codec, this

02:29:14amiconnSoap: The numbers in the wiki are imho a bit too optimistic if they are really from be fore the C optimisation
02:29:44amiconnMaybe they're taken using just the very beginning of elephants dream, which seems to decode easier than later parts
02:30:07amiconn160x128 is now running at 37fps
02:30:27preglowsafetydan: have you ever tried decoding ultra-wideband mode files?
02:32:14Soapamiconn: they are - I did them
02:34:08Soap(they are from before the optimization) - someone tweaked the last two - but the methodology I employed was to watch the entire movie through to the end - write down the ending FPS, then watch the movie again and find two places early on in the film with a matching FPS, and use those places as my "benchmark" for all future tests.
02:34:09 Join jhulst [0] (n=jhulst@unaffiliated/jhulst)
02:34:48SoapI ASSumed this would give me decent numbers w/o having to watch the film repeatedly @ sub 20fps.

02:57:52amiconnCombining Buschel's and my own observations, I suspect that the broadcom "finishup" is in fact not a necessary finishup function, but rather a frame sync feature, that syncs transfer to the internal frame frequency
02:58:38amiconnIt also seems that the broadcom has some kind of internal anti-glitch measure that delays writes if they come too slow
02:58:39 Quit jhulst (Read error: 110 (Connection timed out))
02:59:31amiconnSo it might in fact be fastest to render into an intermediate ram buffer first, then transfer than. And lcd_update() can be optimised more than what that duff's device compiles into
03:00:12Soapamiconn: do you think my FPS measuring methodology is flawed?
03:00:51amiconnMeasuring for a too short time is bad, as well as stopping at a position where fps tend to vary
03:01:29amiconnOtherwise it should be fine, although measuring the whole video would be more precise
03:01:54amiconnIf my theory is correct, that should open the door for significant fps gains...
03:02:11Soapyour Broadcomm theory?
03:02:48SoapIf your Broadcom theory is correct, then why has the Video long had framerates similar to the Photo (w/o a Broadcom chip)?
03:06:33amiconnAnyway, it's a theory that's worth checking. But not right now
03:06:47Soapsince the processor is (basicly) the same between the Photo and the Video - why (for example) does the photo get 25 fps @ 224x176, and the Video gets 26 (identical within the margin of measuring error)
03:07:20amiconnYOu can't compare those. It's a totally different hookup. ANd the Photo will get much better frame rates soon
03:07:22SoapI would assume if the video was getting bottlenecked by the Broadcom, it would have lower FPS numbers than the Photo @ common resolutions.
03:08:00*amiconn goes to sleep
03:08:05SoapOK, I can accept that - why I asked.

10:03:37Nico_Ppondlife: have you tested the latest versions ?
10:03:51pondlifeOK, I might wait until you've done that before testing further - given that I was having crashes with SVN too on Friday.
10:03:59pondlifeNot since Friday
10:04:06pondlifeBut should have a good play today

10:05:25 Join miepchen^schlaf [0] (
10:05:57pondlifeNico_P: One thing that looks odd to me - do you really need playback.c to have a "buffering" bool ?
10:06:10pondlifeI'd think it should come out in the wash in buffering.c
10:06:15Nico_Pit only reads the one from buffering.c
10:06:28pondlifeDoes that have to be public?
10:06:47pondlifei.e. calllers shouldn't need to know the internal state
10:06:57pondlifeIt should "just work"
10:07:01Nico_Pothere threads can find it useful to know the status... I'll try to find something better though
10:07:16Nico_PI think that atone point I'll have to rethink the audio thread logic
10:07:26Nico_Prebasing is done btw
10:07:33pondlifeCheers, will rebuild
10:07:50pondlifeI'd think that the mod in;h=df2f17234ba1fec7518733b5187a52c5e53d90ca should be inside buffering.c
10:08:14pondlifei.e. so that it just ignores extraneous requests
10:08:45Nico_Pit does ignore them but the audio thread will just keep posting them in a loop, which is a bit of a waste
10:08:51Nico_Pand is annoying in the sim too
10:09:11pondlifeAh, but not actually causing a crash or corruption?
10:09:23pondlifeSo this is an optimisation, not a fix?
10:09:35Nico_Pbasically, yes

11:02:30igorrHi, I have just tried rockbox last night on my iRiver-iHP140 and I am really impressed with it. I see that there are some plugins that it does not support, albeit newer players do. One of them is the clock plugin. Does anyone know if there is something in the architecture fundamentally preventing iHP-140 from something like that being supported?
11:03:08GodEater_igorr: yes - the H1x0 hardware has no RTC chip
11:03:32igorrAh, so basically, no clock due to architectural limits of the player, then?
11:03:49igorrThanks for the pointer
11:03:55GodEater_although there are some brave souls that have hardware mod'd their players to include this
11:04:01GodEater_and the process is documented in our wiki somewhere
11:04:19GodEater_in which case the RB build can also be modified to allow use of this component
11:05:15igorrok, I admit −− the player is now a iHP-160, waiting to become a iHP-180 (with a new battery), but I am not sure I have the skills necessary for more invasive procedures :)
11:05:19GodEater_pixelma is our personal "search our wiki for you" service. Please tip her on the way out. :)
11:06:19igorrpixelma: whoa. Thanks for the tip (where is your tip jar, by the way?), but that modification is way out of my league.
11:06:22GodEater_igorr: allegedly it's not that tricky if you have some skills with a soldering iron, though I couldn't comment personally

11:18:58pondlifeAh, yes
11:19:09LinusNnot a problem if it is only him, but how do we know?
11:19:21pondlifeI guess nobody but petur can diagnose it either
11:20:09pondlifeMaybe make a V7 bootloader available, but leave V6 there in case? It's not as if it prevents use of the OF.
11:20:37LinusNmy thinking as well
11:21:02pondlifeUntil we do that, we probably won't get any more info on the issue.

12:21:34Nico_Poh ? when ?
12:21:35pondlifeOnly on H300, but I'm still researching
12:21:54pondlifeLiterally for a second, at track transition
12:22:10pondlife(Or just before.)
12:23:26pondlifeI guess a call to audio_current_track() with a race condition?
12:23:27JetonNico_P: will MoB enable jpeg support for Album Art? And what do you mean in the wiki by "Clean implementation of Album art"?
12:24:06GodEater_Jeton: MoB has nothing to do with jpeg album art
12:24:07Nico_PJeton: jpeg is a different problem. by clean I mean "that doesn't spin the disk on every track change"
12:25:01GodEater_so hopefully will improve battery life somewhat ;)
12:25:03Jetoni see. So ne JPEG support in sight ? But still BMP will be supported in a more "clean" fashion .
12:25:27Nico_PJeton: yes, that's it. jpeg probably won't happen anytime soon
12:26:00GodEater_not until someone writes is anyway :)
12:26:02Nico_Pit'd require having a jpeg decoder in the core, which is bloat
12:26:22Nico_PGodEater_: even if someone writes it, I doubt it'd get accepted
12:27:16Jetonwill this also enable better resizing for the Album Art? Now resizing makes the .bmp look jagged, not smooth.
12:27:21GodEater_true - but unless someone writes it, there's nothing to accept ;)
12:27:25LinusNi think support for embedded jpeg album art would be really nice
12:27:28Nico_Ppondlife: the problem with the track transition is the use of curtrack_id3
12:27:45GodEater_LinusN: embedded too ? You don't want much do you? :)
12:27:48Nico_PJeton: resizing is another problem too
12:27:55pondlifeI reckon there's such demand for JPEG Album Art, it might get into SVN. Maybe as a plugin call to do the decode and resize...?
12:28:30pondlifePersonally, I'd not use it, but I'd like to see the number of "custom" builds reduced ;)
12:28:31Nico_Ppondlife: a plugin would be fine, yeah
12:28:42LinusNi'd rather have it in the core
12:28:50pondlifeAnd AA seems to be one of the main drivers behind custom builds
12:28:58Jetoni think the demand for jpeg is that 'almost' all DAP's use JPEG for album art, and converting stuff from jpeg to .bmp .

12:32:03hasmindis that just normal C syntax?
12:32:06Nico_PJeton: they read the jpeg but don't use it internally
12:32:10GodEater_hasmind: yes very normal
12:32:14pondlifehasmind: Absolutely
12:32:20hasmindlolz kk
12:32:35hasmindguess i am a total noob
12:32:40Nico_PJeton: I'm pretty sure the conversion is done by the computer before transferring the track over to the DAP
12:32:49*GodEater_ would agree with Nico_P
12:33:02Jetonpondlife: that would be much better than embedded, or Track Name.jpg etc.
12:33:25*Jeton agrees with Nico_P too

12:42:52Nico_Pyeah I keep forgetting about that :/ the fix isn't trivial
12:43:04Nico_PjhMikeS suggested timestamping the PCM buffer
12:43:28pondlifeThe info should come from pcmbuf.c, but a simpler fix might be possible
12:43:30amiconnDoes MoB fix the wps bug related to next track info, btw?
12:43:48Nico_Pamiconn: what bug exactly ?
12:44:18amiconnWell, current track metadata is synced to the track change at the pcm level, even if decoding already went ahead
12:44:50Nico_PI think that's the same issue we're discussing
12:45:05pondlifeNot quite...
12:45:18amiconnBut next track metadata isn't, so for around 2 seconds up to the end of a track, "next track" info contains info from 2 tracks ahead
12:45:26pondlifeAh, yes
12:45:33pondlifeSimilar issu
12:46:16pondlifeplayback.c needs to move the current track along only when it gets the PCM callback to denote track change

12:48:10pondlifeThat's the first time that playback knows the track has changed.

12:51:46pondlifeI think so, yes
12:51:53pondlifeSim logfs?
12:51:55Nico_Pthat's what it seems
12:52:40Nico_PI think I could have a static prevtrack_id3 and make the WPS display that during the track transition
12:53:08Nico_Pand use the callback like in SVN to update it
12:53:50pondlifeWhat about the next track problem?
12:54:21Nico_Phopefully it will be solved with the same fix
12:54:24pondlifeWhy not make the audio_current_track() and audio_next_track() return static copies at this point?
12:54:38amiconnIn theory you wouldn't need special measures. Just don't update track related wps info until you receive track change notification from pcm
12:54:41Nico_Pthey do, but not the right ones
12:55:00pondlifeamiconn: That's what I meant.
12:55:10pondlifeHopefully this could simplify code.
12:55:15Nico_Pamiconn: the problem is that the WPS uses curtrack_id3, which changes too eraly for the WPS
12:57:05pondlifeYou need to name the variables carefully - i.e. whether they are decoding or playback related.

12:59:31Nico_Pthe codec and the WPS need to use the same struct mp3entry, otherwise the elapsed info doesn't get updated
13:00:46pondlifeGood point
13:01:05 Join JdGordon [0] (
13:01:17Nico_Pthe codec can't use the one in the main buffer because it can move around
13:01:54Nico_Pthat's why I was thinking of moving elapsed out of struct mp3entry, but it's a big change
13:02:16pondlifeDoesn't this apply to the whole structure really anyway - the timing I mean.
13:02:21Nico_Pand it's probably not even the best fix
13:03:00Nico_PI think the best and maybe only solution is to use a prevtrack_id3 struct and to manage it carefully
13:03:17pondlifeJust a placeholder for the transition window?

13:33:08Nico_Ppondlife: yes
13:34:57preglowsafetydan: like i thought, uwb mode really uses TWO wb decoder state structs, so my current static allocated one will be used twice
13:35:00preglownow, how to deal with this
13:35:48amiconnpreglow: The problem with jpeg decoding is that you need a buffer to decode into. And unlike with preconverted BMP album art, you don't know how big an image the track will have embedded
13:35:57safetydanpreglow, cheat and change speex_alloc to work out of a buffer in iram?
13:36:32preglowsafetydan: i guess that would work
13:36:35amiconn..and embedded jpegs should *really* not be called album art, imo
13:36:52preglowamiconn: i agree there, but it is a solution that exists :/
13:37:12preglowand i am as usual opposed to people having to alter their files for rockbox to be able to use them
13:37:13*amiconn thinks of it more as a problem than a solution :(
13:37:27preglowall the album art i have seen has been in jpeg
13:37:30pregloweven if it isn't embedded
13:37:40amiconnAnd imo jpeg decoding should not be part of the core
13:38:01amiconnWhy wasting binsize if a user never wants to use album art?
13:38:13preglowamiconn: why is the image size a problem, btw? we'll have mob
13:38:17pixelmaI've seen other formats there as well (png IIRC) in my very few tracks that has them
13:38:21amiconnIt could be a plugin that decodes the jpeg and shows it in a viewport on the wps
13:38:25preglowpixelma: blerhg :/
13:38:49Nico_Pamiconn: I just fixed the next track info bug in SVN... the playlist index is still incremented too early though
13:38:55Nico_Perr not SVN, MoB

13:39:23Nico_Pamiconn: decoded an resized, why not ?
13:39:38amiconnResized? __where__???
13:40:02amiconnYou can predecode at 1/2, 1/4, or 1/8, but that's it
13:40:20preglowmaking a simple resizing function is a piece of cake
13:40:28LinusNamiconn: in the same way we resize the bmp's today i guess
13:40:37Nico_PLinusN: we do?
13:40:48LinusNin the bmp resize patch
13:40:56amiconnLinusN: We resize BMPs? Not that I know of
13:41:36preglowanyway, that's not a problem
13:41:39amiconnBMP resizing is way easier than resizing jpeg. BMP can be resized on load because it's uncompressed
13:41:40preglowit won't even each much bin size
13:41:57amiconnAnd btw, the bmp resizing patch is a crappy implementation

13:42:57preglowamiconn: yeah, but not a full size one
13:43:11preglowamiconn: album art files usually aren't 1600x1200
13:43:24preglowyou can resize as you decode, even if you don't do it the way we currently do
13:44:42pondlifeFor non-embededed art it would be reasonable to put a small limit on the dimensions anyway
13:44:43preglowthe core will always waste bin size on features some people will never use

16:33:03pondlifeSorry, I didn't see
16:33:08Nico_Ppondlife: it shouldn't have rebuffered, just gone back to the prev track which should be in mem
16:33:36Nico_Pie normally usefl should have increased without the disk starting or anything
16:34:07pondlifeAh, well I saw an increase in real too, so that indicates buffering, yes?
16:34:24pondlifeNow real is back up to 25MB
16:34:31Nico_Pah yes if real or alloc change, that means buffering is happening
16:34:51Nico_Ppondlife: I'm thinking maybe the !pcmbuf_is_lowdata() condition is the cause.
16:35:05pondlifeHmm, PCM was at 0
16:35:30Nico_Pyeah so refilling wasn't about to happen. strange the pcm buffer was already low when data was first needed though
16:36:09Nico_Pwhat codec was it ?
16:36:20pondlifeAh, it won't rebuffer if PCM is starved so as to allow it to refill? That should only be true if there's useful data...

16:47:38Nico_PI think the !pcmbuf_is_lowdata can and should go
16:47:50pondlifeNot so sure.
16:48:03pondlifeIt should have triggered the rebuffer earlier anyway.
16:48:18Nico_PI agree but I really see no reason why it didn't
16:48:28pondlifePCM lowdata would only have occurred a second or so beforehand anyway I expect
16:49:08pondlifeCould you perhaps remove the !buffering? I can try it here if you want...

17:04:04Nico_Ppondlife: it displays some triangles. but I would like to have exactly like a scrollbar except it could wrap
17:04:04pondlifeNot sure, but you shouldn't access the buffering thread variables
17:04:35pondlifeThread safety is not to be trifled with, I'm afraid.
17:04:58Nico_Pont thread writes the var, others read it... isn't that safe ?
17:07:26pondlifeMay be, but there's always a chance for threads to lock each other out if there are further dependencies.
17:07:38pondlifeBest to keep them totally independent.
17:08:08pondlifecodec_advance_buffer_counters() has a similar test
17:08:30pondlifeProblem is, that is in the codec thread, deciding if it's worth trying buffering.
17:08:39Nico_Pthat's where I thought you had removed the !buffering test, where have you?
17:08:45pondlifeWe should let the buffering thread have a chance to decide
17:08:49 Quit PaulJam (".")
17:08:51pondlifeThe other one, that you put in recently
17:09:14pondlifeIn audio_thread
17:09:31pondlifeI'd make buffering a static bool
17:09:35pondlifeHide it away
17:09:46pondlife(Maybe include it in the debug info.)
17:10:07Nico_Pit's of no use if it's static. I put it there only so that other threads know whether buffering is in progress
17:10:20pondlifeOK, scrap it!
17:10:21Nico_Pyeah it's only be useful for debugging
17:10:36Nico_Pbut I need it! :p
17:10:50pondlifeOK, you need it, but playback.c doesn't :p
17:11:38Nico_Pthe best would of course be to remove the Q_AUDIO_FILL_BUFFER business and maybe give the buffering thread a callback to signal data is low
17:12:04Nico_Phmm I got confused but I mean "do things differently)
17:12:47pondlifeActually, shouldn't the buffering thread deal with this automatically, assuming playback yields..
17:12:51Nico_PI've just pished my commit for the playlist position
17:13:04pondlifei.e. why need to have any artificial control
17:13:13Nico_Pyou mean the buffering thread could deal with the playlist directly ?

17:14:07pondlifeAh, it doesn't know which file to get, does it?
17:14:21Nico_Pthe problem is that there are two different definitions of low buffer. low in files or low in buffered data
17:14:36pondlifeLow in files shouldn't be relevant much
17:14:42pondlifeIt's low in data that matters
17:14:46Nico_PI agree
17:14:54***Saving seen data "./dancer.seen"
17:15:05Nico_Pbut currently the audio thread actively tries to fill the buffer with files.
17:15:21Nico_Pmaybe I should change it so that it provides files when requested by the buffering thread
17:15:31pondlifeYes, that would be better
17:15:52Nico_PI'll try implementing that
17:17:57Nico_Ppondlife: I'm thinking users of the API could register callbacks, kinda like with register_ata_idle_func
17:18:14Nico_Pand those get called by the buffering thread when the buffer is low
17:20:35pondlifeAre you going to scrap those !buffering tests?
17:20:43*pondlife fears git non-synced-ness
17:21:11Nico_Pyou want me to scrap them now before implementing a proper solution?
17:21:25Nico_PI wasn't really planning on it
17:21:26pondlifeWell, I'm fairly sure they're not required
17:21:36pondlifeI don't see what good they do
17:22:02pondlifeThey may save a bit of calling, but nothing that would fail.
17:22:36pondlifeAnd I've had 3 successful rebuffers since removing them
17:22:54Nico_PI'll test without them
17:23:17pondlifeOnly the buffering thread should decide if there's buffering to do.

19:28:57Nico_Pheh, you're going to have another one
19:29:06pondlifeAlready on it... good work there again
19:30:51pondlifeDid you resolve that USB problem you mentioned?
19:31:01Nico_Pnot yet
19:31:36pondlifeOK. I've not seen problems there
19:31:40Nico_Pthe problem is that with the buclose calls now being queue events, they get to the buffering queue after the usb event
19:31:56Nico_Pbut the audio thread thinks they succeeded, somehow
19:32:31Nico_Pso maybe I should just remove all the handles after the usb connection, but that feels a bit extreme and wrong
19:33:32Nico_Ppondlife: I hope you're enjoying the perfect automatic track skip transitions :)
19:34:49pondlifePerfect? What improved?
19:35:21Nico_Psince earlier, not much, but I still find them nice to look at :)
19:35:22pondlifeAh, I've just had the little-bit-of-silence at the start of playback issue.
19:35:50pondlifeI'd guess buffering needs to yield more?
19:36:00Nico_Pmaybe there should be a yield or short sleep after loading each track in audio_fill_file_buffer

19:36:24pondlifeAh, ok
19:36:45pondlifeIs the audio thread waiting for buffering at that point?
19:36:55pondlifeI'd have thought not, as playback has started
19:37:01Nico_Pwould you mind trying to add a sleep(1) in the "do ... while" loop in audio_fill_file_buffer? to see if it solves it

19:42:16amiconnpreglow: Hmmmm, this is with 2.16.1?
19:42:19pondlifeNico_P: The routine audio_load_track() could be scrapped, and it's contents put into audio_fill_file_buffer()
19:42:35pondlifeSame for audio_initialize_buffer_fill()
19:42:39amiconnBecause, I didn't have msac.w problems in the libmpeg2 idct
19:43:03stevenmn1s, where do we go from here, besides that numberOfSamples thing? Increase number of voices on coldfire, or the sample rate?
19:43:10Nico_Ppondlife: I agree for the latter, but audio_load_track is quite long... I prefer to have audio_fill_file_buffer compact as it is
19:43:45stevenmn1s, I found it is easy to see if a file will play right on 44100: plug in USB during midi playback and it will set the sample rate to 44100. I don't know how, but that's what happens.
19:44:01n1sstevenm: I think going 44.1kHz would be nice but dunno if we're running fast enough...
19:44:04stevenmAt the moment, I think all 24 voices active cannot run at 44100 in real time. Just barely under
19:44:39stevenmAnd if this thing is to become a codec, it would need to be fast enough to handler other tasks at the same time, like UI. 44100 sounds better but not really all THAT much.
19:45:22pondlifeNico_P: Hmm, I just went into View Playlist and the marked track was way out..
19:45:44Nico_Ppondlife: after doing what?
19:45:45n1sbut if it becomes a codec the output will have to be resampled if it's not 44kHz...

20:56:01Nico_Pyeah I think they are. no, it's not exaclty that
20:56:18Nico_Pconf_filechunk is the amount of data read per loop

20:56:51Nico_Pconf_watermark is the low buffer watermark. it depends on the codec and audio file

21:14:24TavnosHi there
21:14:30webguest06will you make a sleep mode (like the apple firmwar, cause thats the only reason i'm staying on apple's firmware
21:14:33Zagoralso the sansa DCCPARAMS register contains 0x387, which means it's neither the same as in i.mx31 (should have 'f' last) or mpc8349 (should have '6' last)
21:14:38BigBambiamiconn: So there was an earlier codec failure I didn't notice?
21:14:50amiconnI would think so

21:16:32BigBambiFirstly, which iPod
21:16:32amiconnZagor: Do you know the meaning of those values?
21:16:52pondlifeamiconn: Can we maybe chat about the codec parameters tomorrow? I have to go now, sadly.
21:16:54amiconnYou said that the mpc8349 has fewer endpoints than the i.mx31?
21:17:27 Part pondlife ("Gone")
21:17:28Zagoramiconn: yes, the lowest five bits in dccparams is the number of endpoints
21:17:32amiconnpondlife: I really don't know how this currently works. I just know that there is a low watermark, and it's different per codec
21:17:53webguest06well, i have an iPod video (5g,old school)
21:17:59BigBambiAnd seondly I don't think anyone is working on one. I believe amiconn is looking at suspend for the 1st and 2nd gens as they physically cannot be turned off, but other than that I don't think anyone is working on it. Therefore there won't be one until someone does work on it.

21:23:31Zagorhmm, scratch that confirmation. the i.mx31 docs are a bit fuzzy what the registers are supposed to contain.
21:23:42amiconnMeh. The demac filters are nasty. Not only v1 and v2 can be unaligned in the vector operations, but they can also be unaligned wrt each other :(

21:32:35Zagor387 was decimal. in hex it's... 183. three endpoints.
21:32:57amiconnOh wow
21:33:11amiconnA, eh?
21:33:28Zagorno wonder i couldn't get #5 and #6 working
21:33:46amiconnHow many endpoints do you need for ums?
21:33:56Zagorjust two, so that's fine (plus one for control)
21:34:18amiconnThe control endpoint is fixed, correct?
21:34:31*amiconn doesn't know much about usb, just a little bit
21:34:35Zagorbut I added test endpoints higher up, which obviously didn't work very well
21:34:51Zagoramiconn: yes ep0 is always control
21:35:14Zagorbut I think it is included in the three. size 0 means "device mode not supported"
21:35:15amiconnHmm, for compound devices we would need more endpoints?
21:36:11Zagorno there's something called "configurations", where the host can select what type of device it wants us to be. but I haven't read up on it much. bertrik, do you know more?
21:36:18bertrikamiconn: yes
21:36:37bertrikZagor: as far as i know, there is in practice only one configuration
21:36:51bertrikbut it is possible to have more interfaces
21:37:04bertrikan interface is a set of endpoints
21:37:35Zagorah, I mixed them up
21:37:36bertrikso for example, one interface consisting of 2 EPs for MSC and another 2 EPs for virtual COM
21:38:16bertrikI mean, two interface of two EPs each
21:38:54ZagorI obviously need to read up on this
21:39:37amiconnHmm, the USB stack for my Amiga USB card (not open source, unfortunately) shows quite some details about that stuff
21:40:18bertrikthere is a very nice introductory text called usb-in-a-nutshell, I'll look it up
21:40:32Zagorbertrik: thanks, I've read it already :)
21:41:09bertrikIf you read that, and chapter 9 of the USB spec, you know almost everything you need to know about USB
21:41:37Zagorwell I may have skimmed some sections...

21:43:28Zagorsounds like it should be possible to have MSC and COM in two different configurations
21:44:51mrkikoCan playing with USB be a dangerous activity on some situations?
21:45:07bertrikI think it is very unusual to have more than one configuration, I vaguely remember that windows does not even support it
21:45:11Zagormrkiko: you mean aside from corrupting your disk?
21:45:33n1smrkiko: if you play with it in the wrong neighbourhood?

21:46:46bertrikZagor: i don't know. I can't find the link anymore.
21:47:13amiconnZagor: Very interesting: The Amiga USB stack shows the number of endpoints for each connected device.
21:47:16n1sZagor: couldn't we have a setting on the device that controls which configuration is presented to the host?
21:47:26bertrikCan't we just drop off the bus and reappear as another device with another device id?
21:47:29Zagorn1s: yes we can
21:47:46amiconnIf I connect a mass storage device with a hardware controller (e.g. Iriver H300 or Iomega ZIP USB), they use 3 endpoints
21:47:47Zagorbertrik: I guess that's an option
21:47:57amiconnBut if I connect a PP device, it only uses 2
21:48:02Zagoramiconn: yes, lsusb on linux also shows all descriptors

23:25:04xregininflamewell is there a way to set up subversion so like all i have 2 do is click something and i get the source?
23:25:11xregininflamei have hte .net framework right now
23:25:20scorche|wyou cant build rockbox with that
23:25:21xregininflamei dont like it too much but i can use it really
23:25:33xregininflameits c coding right?

23:25:44 Join japc [0] (
23:25:59xregininflameright but the .net can compile c as well as c++
23:26:07scorche|wif you want to compile, etc on windows, you need cygwin, vmware, or colinux
23:26:09Zagorxregininflame: not for arm it can't
23:26:21scorche|wor m68k, or sh
23:26:24 Quit jgarvey ("Leaving")
23:26:27xregininflamesee im horribly new at this
23:26:45xregininflameill probably run colinux
23:27:01scorche|wany specific reason of choosing that?
23:27:35scorche|wi would recommend vmware, myself

23:27:40rasherscorche|w: Why?
23:27:47xregininflamevmware is better?
23:27:59scorche|wit is easier to set up than colinux

23:28:07xregininflamethats helpful
23:28:12scorche|wrasher: why what?
23:28:28peturor try virtualbox, it's lighter than vmware
23:28:44saratogahas NicoP said anything about the status of MOB? I'm wondering if he think it'll be committed to svn soon
23:28:48xregininflamei have to buy it??
23:28:54rasherscorche|w: why vmware over colinux? I'd imagine colinux being slightly faster, and perhaps slighly better integrated into Windows, whereas vmware is just a closed box
23:28:57scorche|wbuy what?
23:29:10xregininflameoh god
23:29:15xregininflamei didnt mean to start a debate....
23:29:25saratogamaybe you should just read the instructions
23:29:25scorche|wrasher: just for the easy to set up factor, which seems to be a bit important
23:29:46scorche|wxregininflame: vmware player or vmware server are both free and will work
23:29:55scorche|wbut yes, please read the wiki page about it
23:29:59xregininflame..oh ok
23:30:11rasherscorche|w: how about the other points? I've never used colinux myself.. perhaps I should try some time
23:30:24xregininflameok so which is the better enviroment
23:30:33rasherxregininflame: go with vmware
23:30:57preglowsaratoga: it's getting there now
23:31:13scorche|wrasher: i havent used it myself either...i just know it is harder to set up, but is much easier on resource demands
23:31:21xregininflameshould i get the sever or player
23:31:35xregininflame<−− blushes cause he is a complete noob....
23:31:39rasherxregininflame: Player is simpler.
23:31:47scorche|wxregininflame: it doesnt matter...server has additional options which you probably wont need
23:31:57saratogapreglow: looking at the page theres only one bug outstanding, is that because its getting stable or because not many people have tested it?

23:33:01xregininflameok im downloading the installer
23:33:27xregininflameok so about using subversion
23:33:31scorche|wyou dont need to update us :)
23:33:42scorche|wthe wiki tells you how to use svn
23:33:44Nico_Ppreglow: yeah, it's very colose from being committable :)
23:33:50xregininflamei thought u might like to know scorche :)

23:35:54Nico_Psaratoga: there are a fex issues left, like an USB connection bug I need to find a good solution for
23:36:04xregininflameyea im still at a loss....
23:36:07Nico_Psaratoga: apart from that it's mostly testing and cleanup
23:36:18xregininflamedo i use if from the run command from windows?
23:36:39scorche| use it in the terminal of the vmware image when you get it set up
23:37:01xregininflameso svn runs parrell with vm
23:37:09xregininflamewow speelling sucks
23:37:18Nico_Psaratoga: you're welcome to have a look at the code ;)
23:37:24scorche| runs inside the is a program running inside the image

23:40:54preglowhrmph, big hunk of asm: 215% -> 225% for uwb file :///
23:41:45saratogawe really need to figure out what broke codec profiling
23:41:52saratogait would be useful for this sort of thing
23:42:44preglowso it is broken?
23:42:47xregininflamethanks guys
23:42:50xregininflamefor the help
23:43:54 Quit xregininflame ("CGI:IRC (EOF)")
23:44:18saratogapreglow: at least I can't get it to work and no one seems to have tried it recently
23:44:26saratogathe last time i did it was sept 2006
23:44:34preglowit never worked on arm, i think
23:44:45saratogait worked on the pp5002
23:44:52preglowhmm, ok
23:45:10saratogathough there perl script never worked so it was impossible to make sense of the results
23:45:31saratogai started fixing it a while back but gave up when i realized profiling itself wasn't working
23:45:44saratogathough maybe i'm just doing something wrong
23:45:55preglow884% -> 937% (nb), 401% -> 423% (wb). i guess at least it's worth commiting
23:48:35amiconnWhat target is that?
23:48:39preglowamiconn: coldfire
23:48:41n1ssaratoga: I ran a profiling build on my h300 maybe 2 months ago and it created output and all but the script seemed to have trouble so it couldn't match any symbols to the addresses which made the output less than usefull
23:48:42rasherWould nb be acceptable for voicefiles?
23:48:49preglowrasher: i would seriously want wb
23:49:04rasherStill slower than mp3 then
23:49:10rasheror at least not faster
23:49:24preglowthere are a couple of places here that will want some more asm
23:49:28preglowi think i'll hack qmf_filter next
23:49:40rasherHrm.. now I got duplicate entries in Database
23:49:41preglowrasher: these are pretty high quality files, though
23:50:02rasherpreglow: so are the files used on the codec testing page for mp3
23:50:19amiconnpreglow: Do you happen to know whether the penalty for unaligned memory accesses also applies to mac with parallel load from iram?
23:50:19preglowamiconn: i managed to fit the entire mem[] array in registers (evem for order 10), so i expected better performance than this
23:50:31amiconnI would think it does, but I'm not sure...
23:50:35preglowamiconn: well, i would certainly expect it to
23:50:58amiconnThat means it might be possible to get ape -c3000 usable on coldfire then
23:51:22saratogan1s: thanks, maybe its just me then, i'll try it again on arm and see if i can get output
23:51:25preglowi would be surprised if the parallel load was unaffected by alignment
23:52:03amiconnThat is, if the penalty for fetching word-word instead of longword is really 2 cycles, sclarproduct() takes almost twice as long as it could in 75% of all cases
23:52:29n1ssaratoga: the only other problem I had was that ggc ICEs on anything compiled with O3 with profiling enabled but that is probably a gcc 3.4.6 bug
23:54:10preglowamiconn: could you have a quick look and tell me if i'm doing something obviously stupid?
23:54:12amiconnAnd I found that it's possible to fetch values into one of the registers currently processed in the mac instruction
23:54:23preglowamiconn: yeah, i've been doing that for ages :)
23:54:29preglowi even do it in this .S file, heh
23:54:38saratogahurray for pipelining
23:54:41amiconnThat allows me to give one register back for gcc to play with
23:55:02amiconnI can also give back one register in the vector add / sub functions
23:55:25saratogai want an arm target with EMAC or something similar
23:55:38preglowi THINK i can squeeze the den array into registers too, for .order_8, but not .order_10
23:55:38saratogabeating gcc in plain armv4 is harder then i like
23:55:53preglowsaratoga: yeah, it's slightly easier for coldfire
