#rockbox log for 2005-02-12

00:01:50amiconnBagder: The MEMORYSIZE selection isn't included in the simulator makefiles :(
00:02:46Bagderwant me to fix?
00:02:57amiconnYes please, if possible.
00:03:11amiconnI need this for making the size in buffer.c variable
00:04:25Bagderdone
00:05:10amiconn:)
00:05:30amiconnI guess I need to reconfigure?
00:06:02Bagderyes
00:10:29HClwhatcha working on?
00:10:31HCl*curious*
00:11:39amiconnHCl: Making the simulator mp3 buffer size variable, for building rockboy...
00:12:03amiconn(well, not only)
00:20:50 Quit Stryke` ("Friends don't let friends listen to Anti-Flag")
00:20:54amiconnBagder: Rockbox info -> Buffer: 1.676 MB :)
00:21:06Bagderneat
00:21:21amiconnTrying the same with iRiver sim...
00:23:51HClok :)
00:26:03Bagdertime for sleep here, have fun!
00:26:06amiconnBagder: I get a strange effect:
00:26:14Bagderwhat?
00:26:36amiconnI added -DMEM=${MEMORYSIZE} to the DEFINES in both X11 and Win32 sim makefile
00:26:49amiconnWhile this works for X11, it doesn't for Win32
00:27:02amiconnI get a parse error in plugin.c line 501
00:28:08amiconnHmm, it's not the Win32 sim, but the iRiver sims
00:28:25amiconnIs MEMORYSIZE unset in the iRiver makefiles?
00:28:46Bagderno
00:28:51Bagderexport MEMORYSIZE=32
00:28:59amiconnAh, I'm silly....
00:29:04amiconnDidn't reconfigure...
00:29:09Bagderah
00:29:16amiconnNite Bagder
00:29:21Bagdergnight
00:30:58XShocKnight
00:31:44amiconnFunny: Buffer: -9.-283MB
00:31:56linuxstbFLAC decoding is working in the simulator, but I think it's crashing on the target.
00:34:01HClhow big are flac files in general?
00:34:05HCllike, the music files
00:34:12gromit`<−−−−−−−−- like this −−−−−−−−−−−−−−>
00:34:17gromit`(sorry)
00:34:37sneakumsabout 50% of the wav, i found in a brief test
00:35:20preglowahh, i notice how terribly unfamiliar i am with inline asm in gcc
00:35:31HClsneakums: ok.
00:36:17linuxstbIn reality about 60% of a WAV. But obviously, they sound identical.
00:36:20preglowwould anyone happen to know how to format a mac instruction in inline asm? :P
00:37:31XShocKabout FLAC files. wouldn't it be not really reliable to play them in player? i mean batteries will be dead very quickly
00:37:51XShocKi mean discharged, not dead
00:38:05preglowweell, you can pump quite a few hours out of it
00:38:06sneakumsit'd use more battery, but i don't see a reliability problem as such
00:40:21linuxstbBut FLAC may even be lighter on a CPU than MP3 or OGG - we don't know that yet.
00:40:34HClmhm.
00:40:49linuxstbBut I agree, it's probably not the most efficient format.
00:41:40lImbusdepends on what is wanted, I think. battery life is the price to pay for that quality
00:42:25amiconnWhee, Buffer: 31.679 MB
00:42:37lImbusand I doubt the iRiver analog-hardware is of such high quality that one can hear the difference between any of the other codecs (with decend bitrate of course) and FLAC
00:42:45lImbusamiconn: congratz :-)
00:43:21linuxstblImbus: Don't forget the digital output...
00:43:31lImbusof course
00:43:38amiconn@iRiver owners: What does Info->Rockbox info currently tell you about the buffer size?
00:43:42lImbusthat's why I added the word "analog"
00:44:06linuxstblImbis: sorry :-).
00:44:28lImbuslinuxstb: the iRiver after all is a portable music player. I don't know of any digital-input headphones :-9
00:45:33XShocK-9.....
00:45:36lImbusand battery life does not matter if you are stationary with a high-quality digital equipment
00:46:11amiconnXShocK: It will soon be fixed in cvs :)
00:46:23XShocK:)
00:46:46amiconn(It's a simple overflow btw, calculating the "true" MB from the # of bytes)
00:46:47preglowi'd guess the decoding itself is pretty light compared to the mdct based formats
00:47:02linuxstbI agree that I probably couldn't tell the difference between a well-encoded MP3 or OGG and FLAC on the iRiver, but I just prefer to keep my collection in one format, and not go to the effort of evaluating lossy codecs. At least with FLAC I can be 100% I am getting the best out of the hardware.
00:47:04pregloweverything is time domain in flac
00:47:37lImbuslinuxstb: Full ACK.
00:47:49lImbusthis is the advantage of having portable flac.
00:48:08lImbusotherwise the compression ratio would kill any argument as well
00:49:51linuxstbamiconn: Buffer: -10, -298MB
00:52:50amiconnlinuxstb: I couldn't fit my entire music collection on the largest capacity iRiver in FLAC format, while I can do so in MP3. That's a kiler argument for me.

00:53:54linuxstbThat's going to be the great thing about Rockbox on the iRiver - everyone will be happy :-)
00:54:22amiconnI have pretty much everything as MP3 (guess why!), and some OGGs
00:56:03HCli have everything as mp3
00:56:12HClbut i want rockbox to be as compatible as possible
00:56:58 Quit Hohoman ("( www.nnscript.de :: NoNameScript 3.81 :: www.XLhost.de )")
00:57:24linuxstbI think I've said it before, but the "big three" codecs in my mine are MP3 (and MP2 for my digital radio recordings), OGG and FLAC. Unless someone else gets there first, I'm going to be working on those.
00:57:34linuxstb*my mind

00:59:11bagawklImbus, hey
00:59:13lImbusintrested in pictures of the cf-hdd-adapter ?
00:59:20XShocKok. rebuilding
00:59:30amiconnlImbus: Really? I have an 80 GB disk in my archos...
00:59:38XShocKisn't the CF already ata compatible?
00:59:53lImbusbagawk: I did not find it, so I could not scan it, but I still have a picture (photo) of it
01:00
01:00:15sneakumsmy vorbis collection is 6200 files at q2, fits nicely in my iriver
01:00:31bagawklImbus, OK I might go out and get parts to make one, if i get school work done (which I have a lot fo...)
01:00:32lImbusamiconn: I got about 160 GB. I admit, there a part of it I virtually never listen to.
01:00:46amiconnOkkkayyy....
01:00:52bagawkWow
01:00:56lImbus:-))
01:00:57bagawkMy HD is 160gb
01:01:10sneakumsmy biggest disk is 80GB, and it has 40G free
01:01:12bagawkWhat format/quality?
01:01:44amiconnToo bad that anything about 128 GB (137 GB in "manufacturer gigabytes") won't work in either mobile player...
01:01:52amiconns/about/above/
01:01:53linuxstbamiconn: info->rockbox info now showing a buffersize of 30.664MB (I have a 1MB plugin area configured).
01:02:07lImbusquality is mp3 vbr min 192 max 360 or what the real max is
01:02:20amiconnMP3 max is 320 kbps
01:02:42lImbusbagawk: it's not worth the work of getting the parts and soldering the hdd-cf-adpater yourself. I got one cheapo at ebay (about 10 euro)
01:02:51 Quit bagawk ("Leaving")
01:03:15lImbusug. I hope he saw that one before going out and spending that money
01:03:37XShocKamiconn: now it shows Buffer: 21.632MB
01:03:42XShocK31.632
01:03:52amiconnAs it should be...
01:04:30lImbusamiconn: I still cannot build a Gmini or iRiver Sim, not even on a completely new installed BlueChip-cygwin
01:04:58amiconnHmm, strange
01:05:02lImbusjust for info as you all had some problems these days getting sim building
01:05:11lImbusthe problem existed before, and still does
01:05:35amiconnI only had problems building the iriver sim. I fixed that issue.
01:06:01amiconnIf you update to current cvs, you need to reconfigure all your sim build directories
01:06:08lImbusit sounds very simple: while compiling apps/recoder/widgets.c, the include file limits.h cannot be found, thus the symbol MAX_INT is not found and blablabla
01:06:43lImbusI installed a new cygwin (BlueChip style), cvs checkout, build tools, configured new build directory, build, daaang
01:07:07amiconn*when* did you checkout exactly?
01:07:25amiconnThere was a problem (jyp caused it, jyp fixed it) for a while
01:07:28lImbusmhmm. it was either yesterday in the late evening or today
01:08:31CtcpIgnored 2 channel CTCP requests in 1 minute and 2 seconds at the last flood
01:08:31*lImbus is doing cvs update and tools-build and reconfigure and all that on his existing build environment
01:08:38lImbusagain...
01:08:48lImbus(win32 sim that is)
01:09:50XShocKwin32 sim does not build. error on buffer.c:23 :)
01:10:26lImbusI'm tempted to delete the include instruction and replace the MAX_INT by (unsigned) -1
01:10:37amiconnXShocK: You need to reconfigure
01:11:44lImbusuh. even more strange. I think it's worth a multiline-paste. BRACE !
01:11:50XShocKamiconn: just reconfigured, the smae error.
01:11:52amiconnlImbus: Works just fine here. Checkout again, reconfigure and retry

01:14:30amiconnNow that is strange. I have no idea what's going on then. I'm using pretty much up to date cygwin and it works...
01:14:52amiconnOfficial builds are fine as well....
01:15:32XShocKhmm. where MEM is declared?
01:15:50lImbusofficial sim builds ? going to download it...
01:15:51amiconnIt's declared in the Makefile generated by configure (now)
01:16:01amiconnThat's why you need to reconfigure
01:16:24amiconn...and before rebuilding, probably need to 'make clean'

01:19:47HClyea
01:19:50HClit doesn't shut off
01:19:51preglowinsert 'plug out usb' some place in there

01:23:31amiconnLinusN: If I would go getting a H3xx, I would surely run into problems. I don't have a wiggler...
01:23:43preglowLinusN: so this is an archos problem as well?
01:24:00LinusNpreglow: not really, archos handles it a little differently
01:24:31lImbusamiconn: absolutely. I suppose it has to do with the resting environment. cygwin, env$, microsoft-devstudio installed on the same machine...
01:25:12preglowLinusN: on a positive note, it seems binutils support the mac/emac extensions
01:25:20LinusNyes it does
01:25:36amiconnpreglow: No problem on archos
01:25:58preglowi am yet to discover their syntaxes, but i'll probably arrive at the solution given a day or three of intense study

01:44:58etienneanybody have an idea why my power adapter overheats? (fm recorder)
01:45:17etiennei also managed to fry my roomate's power adapter for his archos
01:47:43lImbusuhh.
01:48:20lImbusthere are not much of those techies in here atm. are you able to measure the power drain ?
01:48:52etiennenope, i have no idea how to do that
01:49:09lImbusdo you own a multimeter ?
01:49:19etienneyes i do
01:49:45etiennehow do i do it
01:49:46lImbusdid you ever do anything by setting it to the DC-A -mode
01:50:38etienneno...i tried looking through the menus for some settings
01:50:43amiconnHehe, snow on the player...
01:50:46etiennebut i could only find the battery capacity setting
01:50:55lImbusamiconn: crazy guy :-)
01:51:05etienneamiconn....i won't mind using it for snowboarding tomorrow actually :)
01:51:58lImbusetienne: the fmrecorder has charging control in hardware, I don't think there is a lot to see and configure in rockbox
01:52:12etiennedamn
01:52:51etienneno quick fix i guess then
01:53:08etiennewhat will draining measurement tell me?
01:53:23amiconnetienne: No offense, but check the following: (1) Do you have the correct adapter? What parameters does it tell you? (2) Is it for the correct mains voltage?
01:54:02etienneno offense taken.
01:54:27etienneThe thing is, my roomate have the exact same model and because my adapter (9v 700mA) overheated i borrowed his
01:54:39lImbusa
01:54:41etienneand ended up buring it out
01:54:54amiconnThe fm/v2 adapter should be 6 V / 700 mA ...
01:54:55etienneso he borrowed mine...and it didn't overheat and work fine for him
01:54:58lImbusetienne: the measurment would tell you the current that flows
01:55:18etienneamiconn, the one that burnt out was 6v/700mA
01:55:33etiennebut apparently you can go up to 12v....10 v being desired
01:55:50amiconnNope, not for the v2/fm
01:55:51lImbusnononoooo. that's not v2
01:55:52amiconnThe 9V adapters are for the V1 and the player
01:56:09etiennei see
01:56:16etienneso the 9v is too high for it?
01:56:18lImbusdamn. I just thought half an hour ago that we should clarify this in the battery and charging faq
01:56:31lImbusyes, it is
01:56:52lImbusin my humble opinion, this should still not fry the charger
01:57:10etienneand it doesn't charge by USb either does it (looks on the screen like it does...but doesn't tend to keep a charge long"
01:57:24lImbusit "should" fry the archos, as far as I understood electronics
01:57:54etiennei'm glad the adapter fried and not the archos then....but it makes me wonder why the 6v adapter died
01:58:20DMJCsafety mechanism blew perhaps?
01:58:36amiconnCharging via usb will take rather long, because the current is lower. And the doesn't hold-charge-long problem may be the battery contacts
01:59:05amiconnThis is *not* the same problem as the v1/player battery contacts.
01:59:22etiennei just tried opening it and it looks like i need to solder to get to the battery (the rockbox website only have dissasembly photos for different models)
01:59:52amiconnI don't know there very details, as I don't own a fm or v2
02:00
02:00:01etienneok
02:00:17etiennei hate getting haused by ebay sellers *sigh*
02:00:19lImbusme neither
02:00:43amiconnetienne: eBay? Okay, I ask again: What mains voltage the 6V charger is for?
02:00:52lImbuslol
02:00:58lImbusI thought about it for a moment
02:01:04amiconnPlus, what is the actual mains voltage where you live?
02:01:05etienneit is for 110
02:01:20etienneit worked fine on my room mates archos, which is exactly the same as mine
02:02:02amiconnHmm, strange. As you told he has a 9V charger, I thought he would have a v1 recorder or a player
02:02:04etienneactually, both worked for him, and neither for me
02:02:24etienneno, i got the 9v charger with mine.....baught it over ebay
02:02:46etiennemy charger (9v) is a lot bigger than his(the real archos 6v charger)
02:03:02etiennemine is a 9v 600mA
02:03:11lImbusoh, so you bought a archos device with a universal power supply
02:03:34amiconnetienne: The 9V 600mA charger is the one for rec. v1/ player
02:03:51lImbusamiconn: should it overheat ?
02:03:56etienneits not universal, no settings on it and such and only one plug that fits the thing perfectly....won't be surprised if it came with the archos
02:04:25lImbusand why died the other one, if it was the original delivered with another fmrecorder ?
02:04:36 Join iSheep [0] (~a@dpc691997050.direcpc.com)
02:04:48amiconnlImbus: No it shouldn't. But as the 6V charger overheated as well, I suspect a problem with the box. Perhaps a short circuit in the socket.
02:05:15amiconnPlus the box came with the wrong charger...
02:05:31etienneare all fm recorders V2?
02:06:00etiennebecause this one is definitely fm recorder, doesn't say much else "Jukebox FM Recorder"
02:06:05amiconnThe fm and v2 recorders are the same hw design (LiIon battery), only the v2 doesn't have a radio
02:06:06lImbusall recorders having a radio are version2 recorders, yes.
02:06:17etienneok
02:06:29amiconnThe v1 recorders and player have AA size NiMH batteries
02:07:42iSheepAnyone familiar with the FM Recorder and issues with the headphone jack?

02:08:22lImbusetienne: see http://www.rockbox.org/docs/devicechart.html

02:09:56*lImbus nods
02:10:59etiennei wonder if having dead batterys can cause the charger to overheat?
02:11:22etienneit just never charges enough/constant drain.....i'm speculating here :)

02:14:08amiconnEeeek! CPUAdrErr in snow.rock
02:14:19iSheepI'm having a problem with no audio on my Jukebox. Coincidentally, the LCD screen recently died, so I'm in bad shape. I think the audio is not working, because I think I'm blindly getting a song playing when Rockbox starts up and would (presumably) ask if I want to resume playback
02:16:40lImbusmhmm. that sounds hard to check, iSheep
02:16:59iSheepYeah... not a good combo :(
02:17:29iSheepBut I'm almost positive a song would be playing, because if I press the right button, the hard drive light flickers as if it were switching songs
02:18:45iSheepFor a little bit after the screen died, the audio was still working. I could play a song blindly. But now, for some reason, I can't seem to do that
02:20:05lImbusmhmm. having a broken screen should be no big problem with rockbox, as you're still having voice-feedback like many blind users. but NOT having audio renders a music player somehwat userless
02:20:25lImbusit's still a battery powered external hard drive though
02:21:10iSheepright. well, what I'm trying to decide is if I should buy a new LCD screen so I can see what's going on
02:21:10iSheepI don't understand how the audio could just go out like that
02:21:29lImbusif it's just the connector that's broken, that should be fixeable cheaper

02:25:32iSheepoh ok
02:26:13iSheepwell, anyone with any ideas on where I should go from here? I could go buy a new screen, but I would hate to do that if I'll never have sound anyway. or is there a way to fix the sound?
02:26:16lImbuswb iSheep :-)
02:26:26iSheepthanks
02:27:07lImbuswell, if you feel handy to open the box (or a friend of you), do it, and look what's wrong with the audio connector

02:27:53iSheepyeah, actually I have the thing opened and totally taken apart, really
02:28:01iSheepI just don't know what to look for, because things seem to be okay
02:28:16lImbusfirst you should try if you can't fix it (at least some rumble and crackle) by turning and shifting/pushing the headphone-plug softly
02:28:26lImbusok
02:28:51iSheepI tried that while I *think* I was listening to a song. I didn't hear anything at all in the headphones
02:28:52lImbusit may be very very tiny cracks in the soldering joint of the headphone jack
02:28:54iSheepwoops
02:29:31iSheepwould that be near where the green and yellow wires connect?
02:29:40lImbusplease have a look at the wiki (or the mailinglist-archive), iirc, there is a article about such a problem
02:30:13lImbusI dunno, I never saw a fm recorder
02:30:28iSheepyeah, I'll check it out. should I just search the wiki?

13:11:17rasherokay
13:12:04amiconnThen start the sim and hold down the INS key. The interesting question is: Do you also get keyrelease events between each 2 keypress events?

13:15:06rasherCurious
13:15:30amiconnYou are the first to notice this...
13:16:01amiconnI usually use the Win32 sim, because it's more convenient on windows. Button repeat is working there.
13:16:02rasherMaybe it's caused by versions of libraries?
13:16:38amiconnI don't know. The X11 sim is rather old code, and I'm not much of an X11 expert.

13:31:17rasherOh boy
13:31:19rasherand a fix?
13:31:30amiconnThe repeat handling works *almost* correct in the X11 sim in that it properly detects repeats
13:32:15amiconnHowever, the target button driver is supposed to send keydown, and when repeat kicks in continue with sending keyrepeat
13:32:31amiconnIt should only send keyup at the very end of the sequence.
13:32:42rasherMakes sense
13:32:52amiconnThe x11 driver sends keydown, keyup, the keyrepeat....
13:32:56amiconn*then
13:33:09rasheroh ah
13:33:31amiconnThis cannot work with the event loops in rockbox code, as they need to tell the difference between short & long press
13:34:12 Join Quelsaruk [0] (~kvirc@80.103.137.139)
13:34:17amiconnThey do this by looking at the next event after a keydown. If this is keyup, it was a short press, if it is keyrepeat, it is a long press
13:34:47amiconnThe x11 driver breaks this by sending keyup before the repeat, hence rockbox always counts this as a short press

13:50:21linuxstbSomeone who knows about these things needs to fix the battery status on the iRiver. But the TODO list for the iRiver is getting smaller each day...
13:50:37sneakumsit's scary how fast it's shrinking
13:50:43DMJC?

13:51:26DMJCstill waiting on the audio stuff
13:51:51sneakumspatience
13:52:17*rasher ponders trying to change snake2
13:52:17linuxstbI think Linus wants to make the rest of Rockbox stable before tacking the audio. Which is good, because there is no new audio systerm written yet for him to use.
13:52:29linuxstb^tackling
13:52:43DMJCthe rest of it seems stable enough
13:52:51sneakumsa reasonable approach
13:54:08linuxstbDMJC: Yes, it is. I think the main thing left (outside the audio) is a function to change the CPU speed.
13:54:09rasherDoes anyone know if lcd_clear_display() is expensive?
13:54:32amiconnNot that expensive
13:54:39rashercompared to clearing a rectangle the size of the logo
13:54:50amiconnIt's a simple memset() for the whole framebuffer
13:54:57DMJChas rockboy been uploaded into cvs?
13:55:00rasherwon't bother then
13:55:25amiconnrasher: Clearing a rectangle is way more expensive with the current implementation
13:55:34rasherHeh, alright
13:55:47amiconn...because it clears each pixel individually. Sic!

13:59:25linuxstbHCl: Can you decrease that by moving any buffers to the mp3_buffer ? People have been taking about a 512K plugin size on the iRiver.
13:59:33amiconnIf I manage to get it running in the sim, I'll try to make it run on the archos as well. Should work, and probably even a bit faster than it currently does on the iRiver.
13:59:41linuxstb^talking about (linuxstb can't type today)
13:59:50HCllinuxstb: i did my best, i moved most buffers to the mp3 buffer by making a malloc implementation
14:00
14:00:08amiconnOf course this wouldn't be able to handle all roms, because of the ram size, and the display needs to be shrinked to 1/2
14:00:24 Quit R3nTiL_ ()
14:00:36HCl :p
14:01:15amiconnI also have some ideas how to speed up lcd refresh, but I'll have to look in what order gnuboy spits out the scanlines
14:01:45amiconnThe badness is that gnuboy produces scanlines, but the bytes in the rockbox framebuffer are aligned vertically
14:01:47 Quit webguest85 (Client Quit)
14:01:58rasheryou'll have to do pretty evil screen-chopping though
14:02:13HClmhm..
14:02:33amiconnSo you do one lcd_update_rect() for each scanline, total of 8 per framebuffer "byte line"
14:02:45HClyeae.
14:02:46HClyea*
14:03:08amiconnIf gnuboy always writes sequentially, it's sufficient to lcd_update_rect() in the last scanline of each block
14:03:30HCli set it to the first, at the moment..
14:03:36HCli think
14:03:38HClhm
14:03:46DMJCwhere is the gnuboy src kept?
14:03:52HClno, i just set it to the scanline
14:03:55DMJCI mean the rockboy src heh
14:04:12HClthere's a pretty recent one on my ftp server, but hold on
14:04:19HCli'll make a more recent zip
14:04:45amiconnrasher: I don't need more chopping than on iRiver if I leave out every 2nd scanline & column
14:05:12HClthere
14:05:46HClon ftp://titania.student.utwente.nl
14:06:00amiconnIf this really works, I could go a bit further...
14:06:53amiconnSince it makes no sense to set away 1/3 of all ram (on the archos) as plugin ram, I could make a special build, which does only gameboy emulation.
14:07:37amiconnSince there is RoLo on the archos (starting another firmware file from within the current one), this would be simple to use...
14:08:30rasheryeah
14:08:47amiconnIt could even 're-RoLo' standard rockbox on exit
14:09:21rasherthat'd be a nice way to do it
14:09:50amiconnYou know that I must be crazy...

14:13:53HClseveral solutions have been suggested for that...

14:43:25preglowperhaps even less
14:43:30preglowdepends on the ram
14:43:37HClyup.

14:51:02linuxstbLynx_: I have no idea. There is more (compressed) data to process, but I'm guessing the actual decoding for FLAC is simpler.
14:51:15Lynx_ok...
14:51:37linuxstbI'm about finished with FLAC, and will move on to libmad and then Tremor (ogg), so I can do some speed comparisons then.
14:52:15Lynx_linuxstb: libmad is kinda important ;)
14:52:40linuxstbYes, but I'm already familiar with libmad, so that should be quick to get running on the iRiver.

15:02:16ashridahi'd imagine that declaring huge amounts ofthings on the stack wouldn't be a good idea
15:02:39linuxstbpreglow: If you are using the standard firmware, the plugin size is 32KB maximum - code and data.
15:03:02linuxstbThis needs to be increased in CVS for the iRiver - HCl needs about 700K for rockboy.
15:03:10preglowwell, i'm below that, but my plugin quite obviously crashes rockbox
15:04:47preglowashridah: i happen to to use a 8kb array on the stack, yes :P
15:05:03preglowashridah: so i have to declare these things as static globals?

15:19:12linuxstbpreglow: based on current performance, FLAC is going to need a lot of optimising before it can be used at the same time as equalizers, cross-fading etc
15:19:27linuxstbSo we will need an emac expert on the team...
15:20:59preglowyes, i'm experimenting with it now to find out how it works
15:21:21preglowbut what makes you say this, btw? have you done any tests?
15:22:11linuxstbYes, I have a FLAC "viewer" running on the iRiver - it currently reads the .flac file into RAM, and then decodes it. Current speed is about 8% of real-time.
15:22:32rasherare you writing to disk?
15:22:43linuxstbrasher: No, just discarding the decoded samples.
15:22:48rasherah
15:22:48preglowahh
15:22:51preglowthen bad news for us
15:23:11preglowthat comes as a surprise, really, i'd have thought flac was really fast
15:23:23linuxstbBut I have made zero effort at any optimisation.
15:23:38sneakumsand is that with the iriver running at 11mhz?
15:23:52rasherwhen you say current speed, is that speed *after* having read the file?
15:24:14linuxstbrasher: Yes. It reads all the file into RAM, then closes the file, then starts decoding.
15:24:22rasherokay
15:25:25preglowi hope the ram is severely bogged down
15:25:30preglowthat would explain things
15:25:36linuxstbpreglow: So do it.
15:26:00preglowi know it's running with far more wait states than required, but not how many
15:26:20linuxstbAlso, the 8% is with a 16-bit/44.1KHz file - 48KHz or higher files will obviously be slightly slower.
15:26:41preglowbut still, we've got something to work on now
15:26:42preglowgood job
15:28:43linuxstbAlso, memory usage for FLAC is quite reasonable - the .rock itself is about 69000 bytes, and it needs about 140K of malloc'd RAM to decode a file.
15:30:06rasherSounds very good
15:30:26preglowi'm quite optimistic with regard to cpu usage
15:30:33preglowi think we'll be able to cut that severely
15:30:43HClmrf.
15:31:04HClhow does the audio interface work anyways?
15:31:08HClmaybe i can add sound
15:31:12preglowdunno
15:32:14linuxstbI haven't investigated whether these can be changed, but libFLAC uses a lot of 64-bit integers internally.
15:32:28linuxstbWhich could be another cause of the lack of speed.
15:32:46rasherlinuxstb: did you see the neuros-forum?
15:33:05rasherA FLAC developer is working on removing the need for 64 bit
15:33:22linuxstbrasher: Yes. Last thing I read there was that the developer was going to investigage the 64-bit integers, but I don't think he has yet.
15:33:44rasherSame here
15:33:56linuxstbI'll need to keep an eye on the FLAC CVS.
15:35:19preglowlinuxstb: that's quite nasty, the coldfire doesn't support those directly
15:35:52preglowbut that is an area where the emac will come in handy, the accumulators are 48 bits
15:36:08preglowwhich _might_ be enough
15:36:09linuxstbI'm impressed I'm getting 8% with all these problems :-)

16:15:05preglowas in it really ties the asm statements in with the c codes
16:15:09preglowshares registers and everything
16:16:34HClmhm
16:16:52HClhow many registers does the coldfire have?
16:17:14pregloweight data register, eight address registers
16:17:21preglowwhere the eight address register is the stack pointer
16:17:23HClk...
16:17:37preglowthey can pretty much be used interchangably, with address registers carrying data
16:17:51preglowin our case it also has four 48 bit wide accumulator registers
16:18:24preglowremarkably nice assemby language for this cpu
16:22:14jpburton5150has anyone succesfully compiled on Cygwin?

16:37:45HELPMEi have Rockbox installed on my H140, if think Rockbox messed up the disk.
16:37:47muesli-hihi
16:37:48HELPMENow I canīt load the iRiver firmware!!!
16:38:21HELPMEUSB connection still works with Rockbox though
16:38:33HELPMEand I can still write to disk
16:39:05linuxstbHELPME: What happens if you hold the record button when you turn on your H140?
16:39:23HELPMEbut original firmware stalls at "Read File" (red led off)
16:39:47HELPMElinuxstb: it launches iRiver firmware
16:40:40HELPMEI tried running checkdisk in Windows (when booted from Rockbox)
16:40:48HELPMEit still does not work :(
16:41:23preglowHELPME: read file system?
16:41:32preglowHELPME: what's the status on the battery?
16:41:38HELPMEiRiver firmware stills hangs at startup when loading "read file system"
16:41:50preglowHELPME: have you done a full battery charge?
16:42:08HELPMEpreglow: battery should be ok
16:42:24preglowHELPME: yes, should, but is it? we have had another one of these, and the battery was the problem
16:42:32linuxstbI think Rockbox uses less power than the iRiver firmware, so that could be problem.
16:42:32HELPMEi can't really check it because Rockbox still don't show it correctly
16:42:48preglowHELPME: well, then charge it for an hours time and try again
16:43:16preglowHELPME: the hardware charges itself, so doesn't depend on whether you run rockbox or original firmware
16:43:32HELPMEiRiver firmware normally just says "low battery" or does not turn on
16:43:45HELPMEi don't think that is the problem
16:43:55preglowHELPME: yes, yes, but as i said, we have had another case resembling yours, and then the battery was a problem, so please try
16:44:09HELPMEok
16:44:11preglowit's worth a short anyway
16:44:17preglowshot, even
16:44:33HELPMEright now I am backing up my data
16:44:36preglowjust let the adapter charge for a quarter or something, then try again
16:44:55HELPMEI will charge and try to launch iRiver firmware again later
16:45:06preglowgood
16:46:17preglowrockbox messing up the disk really shouldn't happen, the fat driver should be the same as the one on archos, and that's gotten a lot of testing
16:46:24preglowplus, i've _really_ abused my player, and nothing has happened yet
16:46:32preglowbut time will tell
16:46:42preglowi think i'll go for a walk in the snow
16:46:53jpburton5150rar
16:47:00preglowqpeg
16:47:08jpburton5150i _still_ cannot get rockbox to compile on cygwin
16:47:19jpburton5150it say stuff about the unrecognized architecture
16:47:30jpburton5150but ive got m68k-elf-gcc set up
16:47:37preglowjpburton5150: i tried as well, but gave up
16:47:54jpburton5150haha... so you cant compile either then?
16:48:34preglowi've got a linux box
16:48:35preglowi use that
16:48:44preglowi'm not particularily fond of cygwin anyway
16:48:53jpburton5150alright
16:48:54jpburton5150yeah
16:49:14jpburton5150in a bit i might reinstall a linux partition
16:49:19jpburton5150any recommended ones?

17:19:44Luke1I wonder what that means is wrong if it hangs like that
17:21:16*rasher has no idea
17:21:50HELPMENO! :(
17:21:58Luke1All right. I have an extra 20 GB hard drive, so if that needed replacing it seems like that wouldn't be too bad
17:22:10Luke1but I have no clue what causes a unit to hang like that
17:22:15HELPMEI just feel like I bricked my iRiver :(
17:22:31HELPMEbetter not delete rockbox.iriver :)
17:22:54rasherHELPME: it boots and can write to disk, I doubt it's broken beyond repair
17:23:08HELPMEhope not
17:23:09linuxstbHELPME: If I was you, I would just leave it charging and wait for LinusN to appear.
17:23:11rasherI'm guessing you'll have to wait for someone more in-the-know to come around
17:24:01HELPMEhow does your iRiver
17:24:13HELPMEoriginal firmware behave?
17:24:19rasherMine works as usual
17:24:24linuxstbNever used it...
17:24:27rasherh120 though
17:24:58linuxstbI suppose I could test it for you now - I have a H140.
17:25:08HELPMEmine turns off the backlight under "READ FILE SYSTEM" after the harddisk aktivity stops
17:25:10rasherHELPME: what did you say the error was?
17:25:38rasheroh, it stops in the "read file system" stage?
17:26:11HELPMEit never pass "READ FILE SYSTEM" - harddisk stops reading (and red led) and the backlight is turned off
17:26:23HELPMEI waited 20-25 min.
17:26:35rasherThis shouldn't happen, but you could try running scandisk on it, or even formatting it I guess (after backing up data :)
17:26:51rasherdid you do anything in rockbox before this happened?
17:27:08HELPMEmount /mnt/iriver

17:28:50rasheralso using linux
17:28:58rasherand someone mentioning a vfat bug
17:29:04rasherbut I'm not too sure about the details
17:29:48HELPMEafter USB connection, Rockbox release the connection in 1 sec. or less
17:30:00HELPMEiRiver firmware takes up to a minute
17:30:08rasheryes, it's very snappy :)
17:30:19rasherthat's because iRiver reads the entire disk contents
17:30:24rasherfor some reason
17:30:45HELPMEI donīt think so, the complete FAT maybe
17:31:01sneakumsthe fat is just a map of used and free clusters, it shoudlnt' ahev tor ead that at al
17:31:07sneakumsit seems to read the entire directory tree
17:31:18HELPMEon the FAT, right?
17:31:38sneakumsno, the fat is just a map of used and free clusters.
17:31:43sneakumsthe directories are separate
17:32:41HELPMEare you sure - that seems pretty stupid to me
17:33:40sneakumsas far as i can tell, that is what the iriver firmware does
17:34:13HELPMEhow can you tell - are you an FAT32 expert?
17:35:32sneakumsno, but i know the difference between a file allocation table and a directory tree, and can make a reasonable guess as to which one would need to be read when
17:42:09HELPMEhere is some FAT32 info: http://home.teleport.com/~brainy/fat32.htm
17:42:30HELPMEnotice the "Directory Table"
17:42:44HELPMEwhich is part of FAT32
17:42:56sneakumsbut it isn't the FAT
17:43:20HELPME?
17:43:36sneakumsFAT the file system was so named because it uses a file allocation table to track the used and free clusters
17:43:51sneakumswhich i think is the source of the confusion here
17:52:27HELPMEdamn, dosfsck - FAT32 not supported. http://rpmfind.net/linux/RPM/contrib/libc6/i386/dosfsck-0.1-4.i386.html
17:52:49HELPMEnewer versions must exists
17:52:57sneakumsthe one in Debian is version 2.10
17:53:03sneakumsat least
17:53:14sneakumsthere is a package called dosfstools that has a program called dosfsck
17:53:24sneakumsand the version of the dosfstools package is 2.10
17:53:47sneakumsi've never actually tried it
17:53:47HELPMEI have redhat 9, it's is not installed

18:38:30rasherBut I'd like to try and change the page to be a table
18:38:55rasherguess I'll try and do it - and I'll reverse it if it turns out to be rubbish
18:39:26hubblepreglow: atleast the codec and fm chip
18:40:29preglowthe eeprom is i2c as well, but i don't think rockbox will use that

18:41:32preglowstuff really did accelerate after having a bootloader

18:48:05HClwell, i haven't really looked at it yet

18:49:09HClWhenever realtime sound output is operational,
18:49:09HClpcm_submit is responsible for timing, and should not return until it

18:53:56linuxstbI think I browsed it a couple of months ago...
18:55:20linuxstbAs the Wiki page says, there are probably going to be three separate subsystems - the "audio-playback subsystem", the "codec subsystem" and the low-level hardware drivers.
18:55:30iriverFigure 17-1 (Audio Interface Block Diagram) is quite nice
18:55:51linuxstbPersonally, I'm concentrating on the codecs at the moment. I'll leave the hardware to Linus and the audio-playback to people who are more familiar with Rockbox.
18:56:19iriverWe need some queue struture which can signal when they are almost empty
18:56:32*HCl agrees with linuxstb

19:01:42iriverwho are the audio-playback people of Rockbox?
19:01:48iriverLinus :)
19:03:14 Part webguest87
19:03:36Tanglol you don't let him some time for real life? lol
19:03:43HCl :P
19:04:09iriverit is great that hubble worked on the i2c
19:04:24iriveris working on.. that is :)
19:04:36 Quit hubble ()
19:04:49linuxstbiriver: I think I'm the only person actively working anything to do with the software parts of audio playback at the moment.
19:04:50HClwhats rxak?
19:05:19coobare you guys still planning on using MAD for mp3 playback?
19:05:24preglowcoob: yes
19:05:34iriveri am looking on the i2s and mcf5249 low-level audio driver API
19:05:35preglowcoob: it's a great decoder, and i don't see any other libs as better alternatives
19:05:40linuxstbcoob: yes - I'm working on getting a test decoder working at the moment.
19:06:30preglowHCl: i2c signal sent from transmitting part, i think
19:06:41coobah right - I have no idea of the comparison between CPU power of the iPod's dual ARM's and the coldfire stuff, but I'm not sure how much optimisation of MAD you'll have to do
19:07:12preglowcoob: i don't know how much we HAVE to do, but i'm having a look at the dsp parts of the coldfire as we speak
19:07:31coobthere's dsp parts? lucky bastards :)
19:07:43linuxstbAs HCl (I think) said earlier today, we want to optimise everything as much as possible - the more efficient the playback, the more we can do at the same time (e.g. games).
19:07:46preglownot much to speak of, there is a mac unit
19:07:57preglowwith 48 bit wide registers
19:07:59preglowmore would be nice
19:08:00HClnot only that, the more efficient, the less battery we use
19:08:06HCland the more runtime we get
19:08:13linuxstbHCl: Absolutely.
19:08:17Tangand it will let more battery power too
19:08:31*rasher has an argument with TWiki
19:08:34Tang(oups i was too late)
19:09:35TangABout the audio codec
19:09:55iriverI was thinking about a general decoder function interface
19:09:56iriverwe could use function pointers for replacing the codec functionality
19:10:04Tangan HA memeber was wondering
19:10:22Tangif the seamless playback was lnked with the decoder libbrary
19:10:26Tang or not
19:10:47Tangsince mp123 (used by foobar) is seamless
19:10:47iriverlinuxstb: what function interface would you suggest?
19:10:54Tangnut not MAD
19:10:58Tang:/
19:14:36preglowit will be seamless
19:15:16preglowthe decoder library itself doesn't matter, we'll have to write the code that ties different tracks together
19:15:26preglowand we'll make it gapless
19:15:31linuxstbStarting at the lowest level, I think there's going to be a PCM buffer - the low-level audio driver will run in it's own thread, constantly trying to empty that buffer, and the audio system will be doing it's best to make sure it's never empty.
19:15:52linuxstbIf the audio system succeeds, then playback will be gapless.
19:16:07HClsounds great.
19:16:16sneakumsand the winning will be large
19:16:20HClespecially because i'd be able to link gnuboy directly to that buffer xD
19:16:41linuxstbOnly possibly flaw in playback could be when the sample-rate changes (e.g. from 44.1KHz to 48KHz).
19:16:59HClyou need to be able to set the samplerate of the pcm buffer of rockbox
19:17:07HCletc
19:17:41linuxstbI think we need more detail than that - i.e. the PCM buffer will contain blocks of data, and each block can be a different samplerate.
19:18:01iriverfunction pointer info: http://www.newty.de/fpt/intro.html
19:18:37preglowlinuxstb: i really don't think a gap at sample rate change matters, stuff that is supposed to be gapless won't have different sample rates anyway
19:18:54linuxstbpreglow: Agreed.
19:19:29preglowit's not worth the pain of having to keep track of the position in the buffer at which we'll have to change sample rate
19:19:50HClmhm
19:20:13iriverThere will will need to be small PCM buffer internally in the MCF5249
19:20:35linuxstbpreglow: Not sure if I agree. I think it depends how big the PCM buffer is going to be. We don't want to have to wait for it to empty before starting to decode the next track, just because it is using a different samplerate.
19:20:38preglowthe area around the sample rate change probably wont be guaranteed to be up to par by the phillips codec either
19:20:51iriverIt will be transfered directly via DMA to the I2S bus out to the UDA1380
19:21:02*rasher updates PluginIndex ( http://www.rockbox.org/twiki/bin/view/Main/PluginIndex )
19:21:17rasherIt's slightly less dynamic now, but much easier to read
19:21:37preglowrasher: looks great
19:21:53preglowrasher: that mess really did need to be tableified
19:21:54rasherShould I add iRiver and Gmini to the table?
19:22:00preglowrasher: i don't see why not
19:22:06rasherOkay, I'll go ahead
19:22:37preglowthe information is already there, might as well complete it
19:22:47iriverDMA is performed on the internal audio bus of the MCF5249
19:23:08preglowlinuxstb: i don't think we'll end up with a very large buffer
19:23:20preglowwe might end up with several, as a matter of fact
19:23:27preglowsample rate can be a buffer tag, then
19:23:51iriverthe large buffer will be for undecoded codec data (raw mp3, ogg, flac etc.)
19:23:52preglowif the buffers are small enough, it's more than adequate to only do that check when we change buffers
19:23:57linuxstbYes, "current track" and "next track" PCM buffers would work well.
19:24:31preglowlinuxstb: no, i was thinking a bit more granular than that, several buffers no matter what state you're in
19:24:35preglowthis is the way most audio apis do it
19:25:06linuxstbSo why would we need more than one PCM buffer?
19:25:34sneakumsthe difference between a single buffer with tagged blocks and multiple tagegd buffers is not so obvious to me
19:25:36preglowit's good to have another buffer to work on when you send it to the buffer you've just finished to the codec
19:26:28preglowthis is the way it's done on most audio apis on computers, but there might of course be good reason to not do it this way on a portable
19:26:46linuxstbsneakums: The blocks can be of varying size, the PCM buffers will (I assume) be a constant size.
19:27:04iriverI think a small PCM transition buffer is needed to ensure gapless/crossfading
19:27:17rasherWhat's the name of a joystick-press on the iRiver?
19:27:28iriverSELECT
19:27:37preglowlike you have one buffer, fill it, send it to the dac, and instead of waiting until the das is done with it, you can start on a new buffer straight away
19:27:45preglowthe dac
19:27:50preglowi still type like a pig
19:28:24linuxstbpreglow: are you talking about tiny PCM buffers inside the low-level audio driver?
19:28:44preglowi'm talking about what the audio codecs will pass to the low-level audio driver
19:30:10linuxstbI'm thinking that from the point of view of the high-level codecs and audio API, then will just have a PCM buffer to fill with data. They may themselves need additional PCM buffers, and the audio driver may need additional buffers, but there will be one main "transfer PCM buffer".
19:31:15preglowthe audio driver should not need additional buffers
19:31:33preglowit should just dma the memory it gets straight to the codec chip if it can take more data
19:31:42preglowbarring the need for conversion of the data, of course
19:31:55preglowbut we should try avoiding that
19:32:42linuxstbSo starting from the bottom, do we agree that there is a single PCM buffer the audio driver reads from, or do you multiple buffers?
19:32:54linuxstb^do you want multiple buffers?
19:33:34preglowit's the same thing, really, it's just that with one buffer, a fast decoder will constantly have to watch that it doesn't write into an area of the buffer that hasn't yet been sent to the codec chip
19:33:56preglowbut of course, it can all be wrapped in book keeping functions
19:34:14preglowi don't think i'm very seriously against having one buffer, this is just the way i'm used to doing it
19:34:37preglowif the guys who now the hardware better is biased against one of the methods, that's what we'll picj
19:34:40preglowpick
19:35:23linuxstbBut it should be (mostly) independent of the hardware - we need to abstract the API higher than that.
19:35:52rasherThe keys for the chessclock plugin on iRiver are crazy
19:35:57preglowyep, it will be hardware independent no matter how you do it
19:36:13preglowrasher: then port it to use better keys ;)
19:36:19sneakumsthe idea of threads passing buffers back and forth like a bucket brigade makes a pretty picture in my head, i will say that
19:37:03irivercodec independent is also important - we need a common interface
19:37:06linuxstbsneakums - yes, we need to try and keep it as simple as possible.
19:37:11rasherpreglow: I'll have a look at that later, for now, I be wikihacking
19:37:23preglowsneakums: yes, i like it as well, and the decoder has to call a function to pass it a free buffer, that's where things will block if you've filled all the buffers you can and have to wait before you can decode more
19:37:58linuxstbiriver - yes, that's sort of what I'm looking at in detail at the moment. I'm implementing various decoders using different libraries and then I'll suggest a sensible common API.
19:38:13irivergreat
19:38:28preglowi think we'll need to codec layers as well, one for streaming codecs, and one for non-streaming ones
19:38:38preglowtwo codec layers, damn, i have to start reading shit before i press enter

19:39:11iriveri don't quite follow
19:39:31preglowmp3, ogg = streaming. xm, sid, mod = non-streaming
19:39:50preglowonce the latter is loaded, rockbox doesn't have to think about disk accesses until the track is done
19:40:28preglowwith the former, rockbox has to constantly watch if the audio buffer is nearing its end, and load more data if it's needed
19:41:34rashercould anybody explain this to me: #define CUBE_Z_INC (BUTTON_ON | BUTTON_UP)
19:43:14rasherah, got it
19:43:53iriverpreglow: yeah, there is a lot of things to think about. Didn't think about sid, mod
19:45:15iriverto me sid and mod will also be streaming once they have been through the synth
19:46:48linuxstbNo, I think the difference is that with a streaming codec, you read (and then discard) X bytes of the input stream, and then that generates Y bytes of PCM data.
19:47:09linuxstbWith a SID/MOD/etc file, the input file isn't a stream.
19:47:28rasherCould we honestly claim that metronome is working on iRiver?
19:48:18preglowgotta go the shop, brb
19:48:21rasherI guess I'll put it down as supported

20:13:49preglowyes, that's what we'll use
20:15:01linuxstbTang: Something no-one has really considered is real-time encoders for Rockbox. Recording will come first as WAV-only, and we will then need to think about a lossy encoder that can work in real-time on the iRiver. Maybe the HA people have some suggestions for that.
20:15:24preglowthat will most certainly require custom code
20:15:43TangOkay linuxstb i'll ask at HA place
20:15:44Tang:)
20:16:13Tangbut indeed i'm not aware of anything "builtin" for lossless real time encoding
20:16:26Tang(integer one)
20:17:07linuxstbI'm thinking about lossy, not lossless. For lossless, we have WAV.
20:17:15preglowand with a bit of luck, flac
20:17:48linuxstbA flac encoder would be nice, buit the space savings don't make it a high priority IMO.
20:18:09linuxstbI would prefer 100% stable and reliable WAV recordings.

20:18:37preglownothing is a high priority right now, heh
20:18:39preglowwe need audio
20:19:04preglowbut yes, a realtime lossy codec would rock
20:19:06linuxstbAlso, battery power is an issue with field-recording - so WAV would hopefully allow the CPU to slow right down to the minimum.
20:19:11TangAh sorry i read too quick
20:19:15rashernote to self: change keymappings for stopwatch (and see about making it use the entire screen)
20:19:19Tangi understood lossless
20:19:25preglowlinuxstb: too bad the hard drive is what sucks most power :/
20:19:34Tangindeed i believed there where some libs for encoding
20:19:42Tang'ill ask for both if you want
20:19:50preglowTang: there are, but they are floating point and too slow for us
20:20:00Tangokay i undertsand
20:20:02preglowTang: mostly, at least, i don't know much about it
20:20:06Tangi'm goona ask
20:20:11linuxstbMost codecs are optimised for fast decoding and slow encoding. Not good for the iRiver.
20:20:32Tanghum for lossless you talk i guess
20:20:34Tang?
20:20:49linuxstbTang: No, both lossy and lossless codecs are like that.
20:20:54Tangah okay
20:20:58Tangi'm gonna ask

21:13:03preglowlinuxstb: yes, but if you debug something by printing long longs, you're obviously using them :PP
21:13:37linuxstbI was trying to use a long long to calculate the % decoding speed - to prevent overflows.
21:13:51linuxstbBut I changed the formula instead.
21:13:53preglowahh
21:14:01preglowthat's more qualified use
21:14:48linuxstbBut as I said, libFLAC is full of 64-bit integers, so that's an area to investiage.
21:15:41preglowyup
21:16:48linuxstbI'm eagerly waiting for Linus to work his magic.
21:17:00linuxstb... and get the iRiver running at full speed.
21:17:58 Quit R3nTiL_ ()
21:18:39*rasher has a look at solitaire.c
21:19:08rasherthat sure is a lot of keybindings
21:21:21izzylinuxstb: have you measured if flac requires more cpu time than mp3 to decode? with average compression on both
21:21:52linuxstbizzy: I'm in the process of getting libmad running on the iRiver as we speak. When I finish that, I can do some speed tests.
21:22:27izzyok, that's good :)
21:22:31izzyhow about on x86?
21:22:37linuxstbWhat would you consider "average compression" for MP3? 128kbps?
21:22:59linuxstbizzy: No, I don't think that will be that useful.
21:23:29izzymaybe more, 168kbps perhaps
21:23:49izzyI was just wondering because I haven't tried flac even on pc :)
21:24:16izzyI use ogg for my own encodings
21:24:54izzycoldfire manual says "MP3 decode requires less than 20MHz CPU bandwidth"
21:26:05linuxstbWell, on my 2.8GHz Xeon, a 4 minute FLAC file takes about 2 seconds to decode.
21:26:34rasherUsing linux? Time it
21:27:09linuxstbrasher: I did. "user 0m1.950s"
21:27:14rasherah
21:27:20rasherYou sounded so vague :)
21:27:21linuxstbJust trying OGG now...
21:28:02linuxstb2.594s for a 192kbps OGG
21:28:29izzyhmm
21:29:08sneakums3.3 secs on a 1.5GHz G4 for a 4.5 min ~85kbps vorbis
21:29:19sneakumswith ogg123
21:29:24sneakumsnow there's a useless datapoint for you
21:29:37Tangogg require more processing than mp3
21:29:42Tangit's well known
21:30:16linuxstbJust trying MP3 now - lame "−−alt-preset extreme" gave me 193.4kbps (similar bitrate to the ogg file)
21:30:28linuxstb^sorry, −−alt-preset standard
21:31:29rasherhey, putting "cube" in high-speed mode and limiting the rotation to one axis looks sortof cook
21:31:33rashercool
21:31:57linuxstb"madplay -o wav:" gave me 2.834s. So that compares with 2.594 for OGG and 1.950 for FLAC in my very non scientific tests.
21:33:38Tanglol
21:34:47linuxstbAnd a 192kbps MP2 file was 2.275s - so unsurprisingly MP2 is simpler than MP3 and OGG.
21:35:08linuxstbLet's see how they compare on the iRiver.
21:35:11izzyI would also guess that encoding of flac is easier task than lossy formats
21:35:31linuxstbizzy: Don't make me do all that again :-)
21:35:35izzy:D
21:35:44izzyI didn't mean that ;)
21:36:31linuxstbBut yes, I think the flac encoder is the quickest of all of them.
21:36:38Tanghum not sure encoding in flac 'll be easier than in lossy format
21:36:57rasherCouldn't the 64bit ints be messing things up?
21:37:15rasheror was that in the encoding?
21:37:25rashernevermind me, I'm babbling
21:37:34linuxstbOK :-)
21:37:56linuxstbWhat did you mean by "messing things up"? Do you mean slowing it down, or causing other problems?
21:38:11rasherslowing it down
21:39:06linuxstbYes, I'm sure it is.
21:39:18izzyflac is still in integers only?
21:39:44sneakumscomputers should all be 64-bit by now anyway
21:39:51linuxstbThe decoding is, but the encoding isn't.
21:39:51sneakumsit's the future, dagnabbit!
21:40:09izzylinuxstb: ok
21:41:02izzyhas anyone tried to compile ogg/tremor yet?
21:41:23linuxstbNo, but it's next on my list after libmad.
21:42:12sneakumsfirst you're flac'y, then go mad, and finally you just sit there and tremor.
21:42:18linuxstblol.
21:42:23izzy:)
21:42:29linuxstbI'll be waving at the end of it.

23:05:41TangThis isI've got some answer from amorim on HA board!
23:05:57Tanghe advice wavpack for lossless but also lossy encoding
23:06:15Tang(wavpack is the only one lossy encoder with integer mat)
23:08:02preglowlossless and lossy?
23:09:09preglowi see
23:10:27Tangi send the links:
23:10:41Tanglossless:
23:10:45Tanghttp://www.hydrogenaudio.org/forums/index.php?showtopic=31471&pid=272945&st=0&#
23:10:57Tanglossy:
23:11:00Tanghttp://www.hydrogenaudio.org/forums/index.php?showtopic=27390&st=0&p=272949&#
23:11:11Tangyes indeed wavpack is an hybrid codec:
23:11:19Tangthere is lossy and lossless mode
23:11:20Tang;)
23:11:32 Quit iriver ("CGI:IRC (Ping timeout)")
23:13:06linuxstbTang: Thanks for that - wavpack looks promising, for both lossy and lossless real-time compression. It's definitely one worth testing on the iRiver itself.
23:13:17muesli-brb in 45mins
23:13:37linuxstbDo you know if wavpack is generally considered a good codec?
23:14:39Tangokay i'm very happy to help :)
23:19:05TangHum i've seen a mistake (a lack in fact)
23:19:16Tangin the "firmware feature comparison"
23:19:21Tangfor iHP
23:19:36Tang" Mid-playlist resume ? for iHP"
23:20:03TangIn fct there is mid playlist resume with original firmware since v1.60 (or 1.40 maybe)
23:20:10Tanghttp://www.rockbox.org/docs/features.html
23:20:19Tang:)
23:20:36rasherWhere do I put patches? The SF patch tracker or do I wait for someone here to get it?
23:21:01Tangalso for:
23:21:18Tang" Supports bad path prefixes in playlists Yes Yes ?"
23:21:24Tangthe answer is "YES" ;)
23:21:48Tang" File Delete & Rename −− No"
23:21:53Tangthe good answer is:
23:22:02Tang"file delete yes"
23:22:06Tangrename NO
23:23:41Tang Backlight-on when charging option −−> the answer is YES in fact: you can select light always on from external power source (AC or external battery pack)
23:24:28Tanghum there is quite many mistake i'll correct it and sen an email
23:24:35Tangseems a better ssolution

23:28:47HClwhat about putting sokoban on player?
23:29:08amiconnThat'd be really hard...
23:29:14rasheramiconn: Good, good
23:29:39*amiconn has to investigate a strange problem on Ondio
23:31:09amiconnEither the manufacturer's formatting of the internal flash is messed up, or the rockbox fat16 support has a bug .. :-/
23:31:23rashersniff, fat16 :(
23:31:54amiconnfat32 wouldn't really make sense on a 128 MB flash chip, imho
23:32:02rasherHeh
23:32:27sneakumsmaybe if you want lots of small files
23:32:33sneakumslots and lots
23:32:34rasherI don't.
23:32:37amiconnAfter all, we have to support it (we support fat32 as well), since the archos firmware can only boot off a fat16 partition
23:35:54amiconnsneakums: Why would you want lots of small files on a music player?
23:36:04rasheramiconn: sid support! :)
23:36:09sneakumsi assume you wouldn't
23:36:16rasher(yes I know, not on that device)
23:36:40sneakumsbut fat16 has that 2^16 cluster limit
23:36:45rasherWhere do I put patches for a) solitaire keybindings for iriver, b) logo plugin ?
23:37:21amiconnrasher: Umm, the standard place is the sf patch tracker
