00:24:41road_runnernow to the story
00:27:46road_runnerho it's all in hebrew. I have a log file in hebrew of all my problems with it. twice it bricked after a bad firmware upgarde, one time I don't know why (used the right file), the other - they send me it with the firmware of the iHP 15 GB version (was not published all around the world). another time - the main screen of the unit was ugly broken (but system worked fine....) and another time - was burned by an electrical shock.
00:28:32preglowhahah

00:41:07HClan iriver 15gb? o.o.
00:41:17amiconnH-115
00:43:47HClwhat kind of specs do those have?
00:43:54HClbased on 110 or 120?
00:44:10MoosCamaropreglow: tremor optimisations comitted by Pedro :)
00:44:23preglowMoosCamaro: i know, just spoke to him about them
00:44:29amiconnHmm, that's strange. I believed H-115 was like H-110, 16 MB ram
00:45:09MoosCamaropreglow: :)
00:45:25HClamiconn: mhm... thats what i'm wondering.
00:45:55amiconnpreglow: Mhm, LINE_ATTR ;-)
00:46:08preglowamiconn: might be clever to stuff that LINE_ATTR thing he does in a main rockbox header somewhere, considering your movem discovery
00:46:12preglowahh, yes
00:46:16preglow;)
00:46:48amiconnProbably we don't want to do that anywhere, might waste a fair amount of ram
00:47:15amiconnIt surely helps if the data structure is >= 16 bytes and accessed with movem
00:47:16pregloweverywhere, you mean? the ram waste would be negligable for the few places where we know it would matter
00:47:52preglowespecially considering the possible gain
00:48:04HClyea.
00:48:09HClo.o
00:48:16HClwe waste like what, 12 bytes?
00:48:28preglowworst case, yes
00:48:54preglowor in strange cases, 15 bytes
00:54:03HClheh, tremor guy knew about line attr all along?
00:54:12HClor did he do the improvements after reading?
00:54:34preglowhe asked me about it now
00:54:42HClk
00:54:49preglowbut he suspected it, it seems
00:58:33road_runner115 was probebly based on 110 otherwise it shouldn't have crashed when they put me the wrong firmware un my player and i've updated it to the right one.
00:58:47HClthen rockbox shouldn't have booted on it though.
01:00
01:00:11preglowlemme see if i get this correctly
01:00:16preglowyou've just flashed rockbox on a 115?
01:00:49road_runnerrbx l00ks wow, AMAZIng. way the F*cking go! it has like everyting i ever dreamed of in a player, honest! it's totally amazing. really nice to think that after all that time this would really be one of the best possible players. will donate soon.
01:02:37road_runnerno. they once send me my unit flashed with a 115 fw. (you right it isn't based on a 110 by that..) then I tried to flash it with 120 content (They just told me to ship it back to them. didn't had a solution, their fault, they knew it's the wrong firmware, but still i tried.) and it crashed.
01:04:46amiconnCommit coming up...

01:17:16preglowthe musepack struct is way too large for it to fit in iram in any way
01:18:15RoriI really hate my telco
01:18:24RoriNo free upgrade to 2mbit for me
01:19:01RoriAll because they did not even bother testing the line but rely on an out of date database that is incorrect. I now have to pay for a manual upgrade instead.
01:19:17RoriWhich means they HAVE to do a line test
01:19:45RoriSo unfair :P
01:20:43HClpreglow: split it up in substructs?
01:21:30preglowHCl: yeah, possibly, that or make some of the bigger arrays pointers that we assign somewhere in an init

01:25:09preglowHCl: but yeah, splitting it to two subtructs where one contains the iram stuff might be clever
01:25:32amiconnHmm, I need to take care of the different chargers. The plugs of the iriver and the archos chargers are *very* similar and fit into the 'wrong' socket
01:25:57preglowput some tape on one of them
01:26:04preglowred tape, for the sake of irony
01:27:08amiconnIt might be fatal for the iriver to feed it unregulated 9 volts
01:27:31amiconnThe other way round is no problem, the archos just wouldn't charge

01:35:01preglowmy, musepack math really is shifting hell
01:36:26***Saving seen data "./dancer.seen"
01:36:27preglowhrmph
01:36:37preglowwith a bit of luck, this wont go well with the emac unit at all
01:36:39*preglow gives it a shot
01:37:17HClbad luck you mean?
01:37:34HClcan't you use times 2^shifting ?
01:37:47preglowno, that's not the problem
01:38:10preglowthe emac fractional mode has an implicit << 1 shift of the result
01:38:38preglowwhich might not go to well with musepack
01:41:22preglowwhen you cast a 64 bit int to a 32 bit int, you get the lower 32 bits, yeah?
01:41:50HClyes
01:41:53preglowwell, shit
01:42:07amiconnwhy?
01:42:33amiconnYou could use a union
01:42:43preglownah, problem is i can't provide a 64 bit int
01:42:53amiconnlong long?
01:43:18amiconnOr are you talking about emac?
01:43:23preglowemac can only provide top 32 bits, what musepack does is do a full 32x32 -> 64 bit mul
01:43:31preglowthen shift the result down quite a few bits and cast to 32 bit int
01:45:10crwlhum, is vorbis actually faster than mp3 on rockbox currently?
01:45:27preglowsince i can't provide any of the lower 32 bits (except the top lower 8, but at great penalty), i'll probably have to do prescaling
01:45:33preglowcrwl: sincerely doubt it
01:45:49preglowcrwl: might be with the wildly inefficient dither codecmpa uses
01:45:58crwlpreglow, vorbis2wav and mpa2wav behave differently then?
01:45:58crwloh
01:46:16crwlwith vbr files with similar bitrates (~200-220) i seem to get ~130% with mp3 and ~170 with vorbis
01:47:06 Join t0mas [0] (~Tomas@ip503c08d1.speed.planet.nl)
01:47:29preglowwell, yeah, mp3 uses a really slow dither at the moment
01:47:31preglowmight be that
01:47:37preglowvorbis has no dithering
01:47:45crwlok
01:47:48preglowdither should be an option, imho
01:47:56preglowi most certainly can't hear dithering at 16 bits
01:48:08crwlme neither
01:48:41preglowdithering should also probably be moved from the codecs to the rockbox core
01:49:14amiconnpreglow: Is the downshift after multiply constant?
01:49:56preglowamiconn: sometimes
01:50:12preglowamiconn: they've got a constant shift mul and a variable shift mul, i'm about to study the code to see what's most commong now
01:51:58preglowthe only mul that is really friendly is the FRACT mul, which does a full 32 bit shift down

02:00:49crwlhmm, limiting the number of characters did the trick
02:01:15stripwax_preglow- hi! I actually just finally installed rockbox for first time on iriver.. awesome news to come back to after a vacation. i'm totally blown away.
02:01:43preglowagreed, heh
02:01:52stripwax_i'm hearing it but i'm not believing it :-) figured it was about time to donate to rockbox too
02:03:05]RowaN[i'll donate to rockbox, it would be nice if i could get crossfading to work mind you
02:03:43]RowaN[i donated to zsnes 2 years ago and i still havent been added to the donators list, meh
02:04:00preglowi really prefer to be anonymous when donating
02:04:02nobbehdoes rockbox have a donator list?
02:04:23preglowanyone know how one does a 64 bit mul with only 32 bit hardware multipliers?
02:04:53stripwax_preglow- do four 32-bit mults, shift, and adjust for the sign bit
02:05:11preglowfour 32 bit muls, yes
02:05:22preglowthat explains why musepack is so incredibly, amazingly slow
02:05:56preglowthis friggin requires an arm to be an easy port
02:07:24stripwax_- actually, you'd need to do a bit more than that, as you need to adjust the sign of each of the mults, and that requires more bits.. hmm..
02:07:43stripwax_four 33-bit mults, or four 32-bit mults and some extra stuff too
02:08:56stripwax_I'll see if I can find that section of my dissertation :)
02:12:22preglowahahah
02:12:29preglowi just sped libmusepack up by 100%
02:12:31*HCl still hasn't tried music playback on iriver :X goes to try
02:12:34HClhow?
02:12:37]RowaN[im guessing car adaptor mode is a feature that stops the battery from charging when plugged in?
02:12:42preglowreplacing an innerloop with asm
02:12:48HClnice
02:12:52HClrealtime now?
02:12:57preglowno
02:13:00HCl :X
02:13:02preglow70%
02:13:04HClk.
02:14:45]RowaN[is this the right channel for me to be asking rockbox questions or am i invisible?
02:14:55HClnope, thats the right channel
02:15:06HClcar adapter mode is for making it controlled by car controls, i think.
02:15:08HCli dunno
02:17:12stripwax_Oh, I remember. You need to use a combination of signed and unsigned multiplications: m*n = (a<<32 + b)*(c<<32 + d) where a,c are signed 32 bits, b,d are unsigned 32 bits. so compute bd + ad<<32 + bc<<32 + ac<<64 but of course bc (and ad) are signed*unsigned ..
02:17:46stripwax_dunno if you have that sort of flexibility on coldfire or not
02:18:53preglowgreat, musepack outputs white noise now
02:18:58stripwax_:-)
02:19:40preglowi don't know, gcc does the 64 bit muls for me
02:19:48preglowbut it's obvious a lot of work is involved
02:19:56preglowespecially since coldfire can't do cross register shifts
02:21:14amiconnYou could check how gcc does it
02:23:21preglowwell, it doesn't matter
02:23:25preglowit clearly is heavy
02:23:34preglowand explains why libmusepack is so extremely slow
02:24:05preglowarghh
02:24:11preglowthis doesn't look good
02:25:17preglowi'm really not very confident in gcc's ability to not screw up code around an inline asm bit

02:28:23amiconngood night all
02:28:26stripwax_preglow - what do you mean by "cross register shifts"?
02:29:16preglowstripwax_: well, the 64 bit result obviously ends up in two 32 bit registers, and libmusepack does a lot of shifting on the 64 bit result
02:29:22preglowamiconn: nite
02:29:51HClwhy does musepack use 64bit ints so much
02:29:52HCl?
02:30:07preglowall codecs use 64 bit ints much
02:30:10preglowthey need the precisio
02:30:11preglown
02:30:13HClhrm.
02:30:14HClokay.
02:30:27preglowbut usually the top bits are the only ones of interest

12:02:15preglowarghh!
12:05:24preglowSeed: do you know of any musepack coders that wanna port this? :/
12:07:33stripwax_preglow - how bad is it?
12:08:43preglowi'm not sure, it just know it isn't trivial
12:08:53preglowi've got it close to 100% realtime now, though
12:09:01linuxstbNot sure if anyone apart from me is interested, but I've just added a codeca52 (for A52/AC3) to CVS.
12:09:07stripwax_synth_filter.c, right?
12:09:13preglowstripwax_: yes, that's the major part
12:09:16linuxstbIt's already faster than realtime - it doesn't even boost the CPU all of the time.
12:09:21stripwax_linuxtsb - ooh, nice!
12:09:25preglowthey rely heavily on a full 64 bit mul being available
12:09:55linuxstbOf course, the problem with AC3 at the moment is that all my files are 48KHz.
12:10:07preglowlinuxstb: why not start working on that at once? :)
12:10:26linuxstbpreglow: I'm tempted. Would you be able to send me your resampling code?
12:10:55stripwax_q- why would it need to resample?
12:11:08Rorihas low bitrate mp3 playback been looked at yet?
12:11:11linuxstbThe iRiver hardware can't do native 48KHz.
12:11:18preglowRori: looked at? why? doesn't it work?
12:11:32linuxstbGotta go - back in 5 minutes...
12:11:35Roriwell audio books play back too fast
12:11:36preglowRori: who the hell wants low bitrate mp3 anyway? ;)
12:11:45preglowRori: that's a sample rate issue, not a bit rate issue
12:12:01stripwax_linuxtsb - really??!? blimey. I was fairly certain it could.
12:12:07preglowstripwax_: it can't
12:12:40Roriok sample rate issue then. 22khz 11khz :)
12:12:49preglowhmm, i guess i could make the resampler work in place, but then it gets degraded to just being a downsampler
12:13:58preglowlinuxstb: my code can't be used, it's floating point based
12:14:20stripwax_so does the stock iriver firmware resample 48khz to 44.1khz too? that blows!
12:14:24preglowyes
12:14:29preglowit resamples everything to 44.1khz
12:14:43preglowand it'll have to be a cheap resampling as well
12:14:51preglowcurrently i'm planning on just doing linear interpolation
12:14:51stripwax_absolutely
12:15:51Roriwhat about ac3 via toslink?
12:16:29preglowforget it
12:16:46[solid]linuxstb: maybe you should look at secret rabbit code?:)
12:16:48Rorinot a big deal really
12:17:13preglowsecret rabbit code is too expensive
12:17:22preglowwe can't do that kind of interpolation
12:17:51[solid]that's what i thought..
12:18:03preglowat least the sinc based resamplers are
12:18:13preglowbut apart from them, there's only linear interpolation, and that i can code myself
12:19:04stripwax_cubic interpolation's just a couple of multiplies, adds and shifst per sample. would that be too expensive?
12:21:32crwlbam
12:22:14linuxstbI'm going to send off an email to the linux-audio-dev list - asking if anyone has a GPL'd fast integer resampler.
12:22:40stripwax_preglow - would it make sense to move A00, A01, ..B00,B01,.. etc in Calculate_New_V into IRAM?
12:23:23[solid]hmm... it seems bleeding edge is skipping no more
12:23:35[solid]so the vorbis test will take place today :)
12:24:19preglowstripwax_: they already are in iram
12:24:54crwli actually found no other odd problems with rockbox except that playlist queue thing
12:25:03stripwax_preglow ah ok. are stack local variables always in IRAM then?
12:25:14preglowthe stack is in iram, yes
12:25:31stripwax_preglow cool

12:30:51preglowbah
12:31:18preglowis it possible to make a c macro depend on its parameters?
12:31:44preglowno, of course not
12:31:52preglowi'll have to do it with c code in the macro
12:32:27stripwax_preglow? how do you mean, 'depend'?
12:34:32preglowi need to output one asm instruction if a parameter is above a certain threshold
12:34:42preglowand another if it's below
12:34:45preglowbah
12:35:09stripwax_could probably achieve that using template metaprogramming in C++ but.. not in C preprocessor I don't think
12:38:30stripwax_no, wait: could the parameter come from an arbitrary range or one of only a few likely values?
12:39:04stripwax_^preglow
12:42:44stripwax_.. because if so, you could use ## to contenate the argument value into the macro name itself..
12:43:09preglowahh, sorry, busy for a bit
12:43:22preglowi can't, the i need to shift right for some values, and left for some others
12:43:25preglow-the
12:45:08stripwax_that should still work.. what are the exact values and what is the threshold? (i'm thinking -32 < v < 32 and threshold is 0 but I'm probably thinking wrong)
12:46:38preglowvalues range from 32 to around 15 or something, i guess
12:47:07preglowonly 32 needs right shift, rest needs left shift
12:47:15stripwax_so something like SHIFT( a , n + 32 ) where #define SHIFT( VAL, NSHIFT ) SHIFT ## NSHIFT( VAL ) where #define SHIFT_0( X ) something, #define SHIFT_1( X ) something etc
12:47:51stripwax_oh.. silly question but are the values constant or not? if not, then obviously you'll need to use C code
12:47:58preglownot always constant
12:48:13preglowfuck this, i don't have time
12:51:07stripwax_preglow yeh. i can take a look if you like.
12:51:17preglowi have one more opt uncommited
12:51:34preglowand that's an asm version of the FRACT multiply macro
12:52:01stripwax_hmm.. will the compiler optimise away the Data var in Synthese_Filter_float_internal? seems to be just a copy of OutData
12:53:02stripwax_preglow cool
12:59:34stripwax_preglow wow, so MAKE_MPC_SAMPLE does a 64bit multiply by 1<<14 rather than just a couple of shifts?! is that the thing you're optimising right now?

13:06:26preglowonly thing i've done that actually works is an asm version of MPC_MULTIPLY_FRACT
13:07:06stripwax_ok. math.h is pretty crazy
13:07:15preglowyes
13:07:16preglowit is
13:11:05preglowbut we have serious problems anyway
13:11:50preglowMPC_MULTIPLY_NOTRUNCATE, for example, shifts the 64 bit answer 14 bits down
13:12:06preglowfor us, that quite simply translates to a sixteen bit loss of precision, if we want any semblance of speed
13:12:36 Quit edx (Read error: 110 (Connection timed out))
13:14:27stripwax_Could we do it all in emac and use an 8 bit fractional part instead of 14?

14:20:41LinusNhi
14:20:41crwlyes, i'm not expecting :)
14:20:51crwlthegeek, i think the hardware always resamples to 48 kHz no matter what
14:20:58LinusNSlasheri: i alse get the stuttering on the second load
14:20:58thegeekwell
14:21:02thegeekI resample using foobar
14:21:03LinusNalso
14:21:15thegeekso it's already resampled before It is sent to the card
14:21:28thegeekif it can give bitperfect digital
14:21:33thegeekI am tempted to just use it
14:21:34SlasheriLinusN: ok, that might be caused due to too small file chunk size or too low filebuffer watermark level
14:21:39thegeeksince the kx drivers rock

14:25:42thegeekand then
14:25:51thegeekperhaps the iriver does something funky too
14:25:57*LinusN is impressed with the speed that new codecs are added
14:25:58thegeekI'm not about to trust the iriver fw;)
14:26:20preglowhaving linuxstb back does speed up things, yes ;)
14:26:43ashridahLinusN: heh. all it takes is for someone to make the first small hole in the dam
14:26:58ashridahthen it quickly breaks into a torrent
14:27:41preglowwe'll have musepack soon as well
14:27:42nobbehnow someone do .SID :P
14:27:46preglowbut it's not realtime yet
14:28:09nobbehi think the wiki says it is :S
14:28:14preglowno, it doesn't
14:28:23preglowit is realtime if i add this remaining opt
14:28:23preglowhmm
14:28:25nobbehoh, my bad
14:28:35nobbehwas thinking of wavpack
14:29:31preglowwavpack is by far the fastest codec we have, so yes, that's realtime ,)
14:29:35preglow;) <-
14:30:05linuxstbI've written codecmpc, but it doesn't work - the decoding fails immediately. But unless anyone objects, I'll add it to CVS so others can look at it.
14:30:14preglowdavid bryant's doing a great job on that one
14:30:49 Quit bumi ("( www.nnscript.de :: NoNameScript 3.81 :: www.XLhost.de )")
14:32:23preglowlinuxstb: sure, why not
14:32:52preglowi'll commit this last musepack thing so it at least has a modest chance of playing with some semblance of realtime speed
14:32:54LinusNdavid has cvs access now btw
14:33:03preglowLinusN: excellent
14:33:11preglowthen we'll probably see wavpack codec support soon
14:33:26linuxstbfiletypes.c currently uses #if CONFIG_HWCODEC == MASNONE to decide when to increase the number of extensions/filetypes - anyone have any better suggestions?
14:33:30preglowwavpack is by far the best lossless codec for portables
14:33:33preglowthanks to its hybrid mode
14:34:02LinusNlinuxstb: not at the moment
14:38:34 Part LinusN
14:38:50preglow101% realtime.....
14:41:10linuxstbOK, codecmpc is in CVS now.
14:45:40preglowyo
14:45:56preglowdidn't audiobuffer_insert have a limit on 32kb?
14:46:14ashridahSlasheri: still around?
14:46:21linuxstbpreglow: I tried reducing the buffer to 4K, and it still failed.
14:47:13linuxstbBut I'm sure it's just something simple like that that's preventing it working.

14:54:00stripwax_reckon i'll be ok charging my iriver from a 6v adapter instead of a 5v adapter? my other adapter is at the office and i never got round to making the usb charger :)
14:54:30crwli have used four AA batteries that should make up about 6 volts, at least when full, and that has worked ok
14:54:34crwlbut don't quote me on that
14:55:04preglowstripwax_: never ever play around with adapters
14:55:27stripwax_preglow?
14:55:29preglowstripwax_: use the original one at all times
14:55:43crwland you also need to check the polarity
14:55:49crwlso yes, maybe don't play around with them :P
14:55:50preglowh1x0 will fry itself given half an excuse
14:56:14DaKi][erdepends how the charger circuit for the lithium polymer battery works
14:56:33stripwax_yeh, it's 6v/2a/correct polarity. seemed to work.
14:56:44crwli have also successfully used a 4.5V charger that came with iriver iMP-150
14:57:58stripwax_maybe i'll just cannibalise the charger and cut the plug off .. it's not a charger i need or use anyway
14:58:30preglowlinuxstb: have you checked out if logf says anything interesting while loading codecmpc, btw?
14:59:59linuxstbI don't know how to use logf...
15:00

15:17:24Slasherinow mp3 test has gone over 7 hours and still 62% battery left
15:17:46crwlodd
15:17:52crwlexpect it to drop to zero soon :P
15:17:56Slasheri:D
15:18:01linuxstbHow long does the iRiver firmware play for?
15:18:12Slasherii haven't tested that
15:18:21preglow16 hours at 128kbps, they say
15:18:32crwli get maybe 8-10 hours with some track switching etc
15:18:40preglowyeah, me too
15:18:52crwlthough i mostly have oggs, it's maybe even less
15:19:25crwli think i've never run out of battery and i rechage almost always when there's about 50-75% left so i don't know exactly
15:19:29yngwii do a benchmark right now, been playing at 128kbps, vol 20 and eq normal for 4.5 hours and still all bars full
15:19:32crwlnever in normal use, i mean
15:20:00linuxstbCan I use logf from inside a codec plugin?
15:20:00bipakwould be great if rockbox gets longer playback time :)
15:20:21yngwibipack: i'm counting on it :-)
15:20:24crwlcurrently ogg vorbis is faster than mp3, at least according to my test
15:20:25SlasheriHmm, there has been few oggs too in the test (in one folder there was vorbis files and i didn't remembered that). mp3/vorbis switch caused some buffering problems but test has been running continuously without bigger troubles.
15:20:26bipakyngwi: :D
15:20:30preglownot very realistic

15:57:05ashridahdwihno: there are replacements for the ipod that fit in, and you can find li-poly ones that also fit
15:57:12preglowvery, very modest speedup
15:57:17ashridahebay has them, plus a few other suppliers
15:57:18preglowmakes me wonder if i've done something wrong
15:58:03dwihnoashridah, markun: so it won't be impossible to get "new" batteries in say, 1, 2, years?
15:58:29ashridahdwihno: nope.
15:58:47ashridahand you'd definently want a new one, not one that's been sitting on a shelf
15:59:18webguest39larger capacity "Ionity" batteries are pnp from dap store
15:59:18markunashridah: Does that matter much with li-poly?
15:59:27yngwii read, the ipod batteries work pretty good
15:59:46markunYes, I have a 2200 mAh now, works very nice.
15:59:52ashridahmarkun: so far as i know, li-poly degrade over time too
16:00
16:00:07yngwimarkun: does it fit in the case easy??
16:00:07ashridahi don't know if it's as fast as lithium ion
16:00:30markunyngwi: It's very tight, but it fits.
16:00:53markunmaybe 1 mm thicker.
16:01:21yngwithats ok... 1mm is not much
16:02:00crwlwhat about larger hard drives, are there any >20G 1,8" drives that would still fit into the H120 case
16:02:10crwl(the H140 is a few mm's thicker)
16:02:49yngwicrwl: i remember a few threads at misticriver on that topic
16:03:09preglowi did do something wrong, big boost
16:03:14yngwii think in a h140 someone put a 60GB HD
16:03:16preglowfrom 113% realtime to 140% realtime
16:03:42preglowit also outputs white noise :PPP
16:03:46markuncrwl: right now there is a 30GB drive that fits in the H120, later this year toshiba will release a 40GB.
16:03:57dwihnomarkun: is the playback time extreme with 22mah?
16:04:13markundwihno: 29 hours mp3 with the original firmware.
16:04:32preglowi am a fool
16:04:33markundwihno: But I did not do much testing.
16:04:36yngwiwow, thats amazing
16:04:40crwlmarkun, ok
16:04:44markun18 hours ogg

16:09:34dwihnoDamn it looks cool!
16:10:07yngwidoes the remote use much power??
16:10:38stripwax_preglow - maybe for crossfading?
16:11:59preglowstripwax_: we never run two codecs simultaneously
16:12:16preglowstripwax_: we run first one until it's squeezed dry of data, then the other
16:12:47stripwax_preglow do we have a larger pcm buffer to do that? or is it a very quick crossfade?
16:13:07preglowmy, what a nice little codec
16:13:09preglow163% realtime
16:13:16stripwax_i should probably shut up anyway, what do i know :_/
16:13:17preglowstripwax_: crossfading is already done like that
16:13:27preglowstripwax_: it's one secondish
16:13:37stripwax_preglow cool
16:13:52preglowbut ok
16:14:00linuxstbpreglow: If you've optimised liba52, then please commit - I have one high bitrate 6-channel file that won't decode in realtime.
16:14:02preglowi'm removing a malloc in liba52 and declaring the main struct static
16:14:30preglowso we can't instantiate two liba52 at once
16:15:17ashridahSlasheri: hm, was that last patch to playback.c supposed to address the issue? it's still skipping here

16:47:20linuxstbIt's fixed my stuttering track - 448kbps 5-channel AC3.
16:47:24preglowdidn't need more improvement than that, no?
16:47:43preglowwell, 150% performance improvement doesn't hurt
16:47:54linuxstbThe CPU is boosted on my 5-channel track....
16:48:39linuxstbBut it's not boosted all of the time :-).
16:49:12linuxstbSo yes, I think that's all we will ever need.
16:49:22linuxstbIt will be hard to get all the other codecs that fast.
16:49:24preglowdoes it decode all five channels before mixing down?
16:49:40linuxstbI think so, but the downmixing happens inside liba52.
16:50:03preglowyeah, i know
16:50:19preglowhmm
16:50:43preglowsomeone should try djbfft + sorting to speed up the imdct in tremor
16:50:55SlasheriHmm, that ac3 passthrough via toslink would be nice feature but perhaps it's impossible to do due to hardware limitations?
16:51:26preglowdon't think it's possible no, but i'm just guessing
16:52:31preglowbut shop, later
16:53:27thegeekbtw
16:53:32thegeekwhat happened to that midi codec?
17:00
17:03:24preglowstevenmn is busy with other stuff, i guess
17:05:53preglowlinuxstb: please do check if you can hear any quality differences, btw, it should also be more accurate now, but i'm not sure
17:06:04webguest39is lame mp3 gapless ?
17:07:05preglownot yet
17:07:50*Rori waits with bated breath
17:08:04Roridon't mention gapless when I am around :)
17:08:09webguest39will it be gapless ?
17:08:13Roriheh
17:09:12webguest39otherwise I'll have to transcode my 180 gigs of mp3 to ogg
17:09:28preglowit will be
17:09:31stripwax_webguest - no point transcoding!
17:09:35preglowhaha
17:09:45preglowtranscoding wont get you any closer to gapless
17:09:49preglowor wait, it will!
17:09:53preglowbut no
17:09:57preglowit will be gapless
17:09:58webguest39lol
17:10:09webguest39I get the picture preglow
17:10:14stripwax_:-) it might be gapless, if it's rtr
17:10:30linuxstbpreglow: It's hard to judge the quality with 48KHz files, but yes, they did seem better.
17:10:31stripwax_^transcoded using something that understands the lame tags

17:12:11phil-Hi all I would like to point out if i may, this topic on the RockBox forum: http://forums.rockbox.org/index.php?topic=775.0
17:12:16linuxstbpreglow: No, they are definitely not worse.
17:12:19phil-looking for feedback
17:15:08preglowphil-: does it patch the bootloader itself?
17:15:23preglowphil-: patch the firmware, i mean
17:15:42phil-it comes with a patched bootloader, there are two versions for h120 and h140 at this early stage
17:15:50phil-the file size is 1.95 meg in total
17:16:23preglowdistributing a patcher firmware is really shady
17:16:30preglowiriver has copyright on the firmware
17:16:41*preglow sighs and corrects himself: 'patched'
17:16:50ashridahyou realise, of course, the only reason rockbox themselves don't distribute a pre-patched firmware is because they don't have distribution rights, don't you?
17:16:56phil-thats a point which i forgot to consider until now
17:16:59preglowyes
17:17:00phil-I remember reading about it
17:17:05preglowthat's the entire reason why i made fwpatcher
17:17:12preglowwhy can't distribute a ready patched firmware
17:17:15ashridahwhich is why someone made the fwpatcher
17:17:16preglowWE
17:17:23preglowgod what is wrong with my brain
17:17:30preglowit's not compatible with writing
17:17:36phil-well I could easily modify it, to run your patcher instead
17:17:47preglowwell, sure, but my patcher also is a gui tool ;)
17:17:54preglowso you need to wrap it somehow
17:18:02Suckayou could make your prog automatically download the firmware and then patch it?
17:18:24phil-i can do that, ive got it to autodownload files and run them
17:18:33Sucka:D
17:18:43phil-so let me get this right for myself
17:18:45phil-if u dont mind
17:18:59phil-i get it to download the firmware, then run fwpatcher?
17:19:12phil-if you wouldnt mind me distrubuting it with the software preglow
17:19:34preglowyou can do whatever you like with it
17:19:44preglowbut it's got its own gui, so it wont be as automatic as you like
17:20:07preglowwhat do you program in?
17:20:43phil-i was thinking, i could include it but the user would have to find the .hex file themselves using the software
17:20:55preglowyes, exactly
17:21:02preglowbat what language are you programming in?
17:21:12preglowif you use C or C++, you can just steal my patcher routine
17:21:23preglowfor other languages i have no idea
17:21:25phil-at the moment im using nsis to basically make it all, its very versitile as I lack the skills for C/C++ yet
17:21:34preglowahh
17:21:48phil-the shame :(
17:21:48phil-lol
17:21:51preglowhahah
17:22:12preglowbut yeah, please don't distribute ready patched firmwares, that could put us in a bad light
17:22:25preglowand reveal us like the nasty buggers we are
17:22:25phil-yes that was my own fault, sorry
17:22:44stripwax_maybe i'll tweak fwpatcher to accept cmdline args?
17:23:02phil-that could work?
17:23:17preglowyup
17:23:17phil-because if i download the firmware to the same directroy as where fwpatcher isntalls
17:23:31phil-im sure it would be quite easy to do it automatically
17:23:38stripwax_yeah
17:24:17phil-so do you belive the concept of what im doing is worthwile? because i found all the relveant info for rockbox on the site eventually, but it could be quite daunting
17:24:21phil-for a new user
17:24:49stripwax_i quite like the idea, especially if it's automatically downloading the latest versions of everything.
17:24:53preglowSlasheri: around?
17:24:57Slasheripreglow: yes
17:25:13phil-yeah it does work, i have a finshed version here
17:25:18phil-just without documentation at this time
17:25:22preglowphil-: if enjoy what you're doing, just go ahead, if it's usable, someone will use it
17:25:33preglowSlasheri: how do you do mp3 gapless at the moment?
17:25:37phil-thanks preglow
17:25:57preglowyou can use fwpatcher for whatever you like
17:26:14Slasheripreglow: i am not really sure.. :) i look for some headers and then cut all silence at beginning of tracks
17:26:45Slasherii hope someone will do a better gapless handling for mp3
17:27:04preglowSlasheri: i'm looking at foobar2000 mp3 source code at the moment, and it seems to do two things:
17:27:19Slasherii haven't managed to implement lame gapless right way at the moment
17:27:34preglowskip an amount equal to the delay field in the lame info header plus a constant encoder delay amount at the start
17:27:50linuxstbI think the first thing we need to do is to switch to using samples in elapsed_time and "length". All the codecs work at the sample-level, so we lose a lot by converting to ms.
17:28:17preglowand cut an amount equal to the padding amount specified in the lame header minus the constant encoder delay
17:28:22SlasheriHmm. Do you know how to parse those fields from mp3 file? I guess that current id3 structure has not all of those fields
17:29:17 Quit Sucka ("a bird in the bush is worth two in your house")
17:29:17preglowit's not in id3
17:29:27preglowi thought you had made a lame info header parser?
17:29:33preglowor do i remember incorrectly?
17:29:34Slasherithere is also mp3info structure, it has at least padding
17:29:43Slasherii haven't :)
17:29:45preglowwhere in the source is the reader?
17:29:55preglowfor mp3info
17:30:01Slasheriin playback.c
17:31:03phil-preglow: is it possible if you have any free time to make a new fwpatcher which supports commands? would be grateful
17:31:14preglowphil-: sorry, i'm out of rockbox time for today
17:31:20preglowphil-: and i'm not in windows anyway, can't test it
17:31:46phil-ahh i see sorry to bother
17:31:48preglowi think stripwax said he could do it ;)
17:31:58phil-sorry to bother you*
17:32:03Slasheripreglow: and that mp3info structure can be found from firmware/export/mp3data.h
17:32:34preglowi see
17:32:42preglowit's just skipped at the moment
17:34:03stripwax_preglow/phil :-) sure, if I get a minute. I can probably hack it, actually...

17:40:03preglowit might in the future
17:40:45preglowthere is a lot of work ongoing in the area of sound right now
17:40:55bagawkIt should be somewhat easy now, concidering they already can decode mp3s
17:41:13bagawk(and play)
17:41:23preglowbagawk: on iriver we might even be able to use a complete voice synthesizer
17:41:40bagawkThat would be neat :)
17:42:03preglowyes it would
17:42:42ashridahTwc_12: unfortunately, the heavy development at the moment means that support for voice menus hasn't been addressed yet. i imagine it will get done when most of the basic audio playback features are stabilised and thoroughly debugged, tho. From what i know, it's an important topic for the rockbox developers.
17:43:40Twc_12okay ... thank you very much

18:11:43RoriIt asks resume on everything I noticed
18:11:55Rorieven if you had previously stopped playback before shutdown

18:16:58Rorihas anyone agreed on button functions yet? especially for the remote
18:17:00stripwax_markun - to turn it on??
18:17:12markunstripwax_: to resume
18:17:22Slasheripreglow: Oh, that's great :)
18:17:28Slasheripreglow: you should do it in codecmpa.c

18:21:23Slasherii think battery should last longer with pure mp3 files only
18:21:30Slasherilinuxstb: good :)
18:21:49linuxstbWe should move this stuff out of playback.c though.
18:22:10Slasheriyes we should
18:22:35linuxstbMaybe something like apps/codecs/metadata.c ?

18:24:43Slasherisomebody should do a better test.. Maybe i will do someday :)
18:24:44preglowi wonder if the hardware keeps us from draining the battery too far
18:24:51stripwax_linuxtsb - does the source for ogginfo help to figure out total duration?

18:24:57Slasheri:D
18:25:18preglowdraing a li-poly battery too far will reduce it's lifetime
18:25:38preglowSlasheri: but, yo, can i read the mp3info struct from codecmpa?
18:26:00Slasheripreglow: yes, just check the codec_api structure
18:26:03preglowaight
18:26:12nobbehpreglow: if it runs down fully in usb mode, it WONT start at all after. Most stuff will power on for a few seconds...
18:26:28linuxstbpreglow: Do you mean ci->mp3data ?
18:26:33preglowmaybe
18:26:36Slasheripreglow: that battery draining is not a problem because i will order ionity battery as soon as 1900 mAh model will be available
18:26:47linuxstbCheck apps/playback.h for the ci structure.
18:26:54linuxstb(codec_api structure)
18:26:58preglowSlasheri: i'm meaning generally, if the hardware doesn't keep us from drawing too much, we have to restrict it
18:27:01Rori1900mAh.....droolz
18:27:07Slasheripreglow: ah, that's true
18:27:13Slasherihardware will drain it too empty
18:27:28preglowa li-poly cell should never be drawn below 3 volts
18:27:33preglowat that point the lifetime is reduced

18:29:55stripwax_HCI - 2300???
18:30:27Slasheripreglow: battery monitor says it's 3.13V currently (0%)
18:32:12preglowi wonder if the reading is accurate
18:32:15preglowi bet linus knows that
18:32:21Slasheripreglow: 2.5V, hdd failed to spin up and then hardware turned off
18:32:47preglowhmm
18:32:56HClyes. 2300
18:33:00HClebay sells 2300 too.

18:40:21preglowSlasheri: is there a gapless attempt in codecmpa.c that i should be aware of?

18:41:12Slasheriand you can also comment out the detect silence hack if it causes troubles
18:41:59preglowso you actually use id3 tag to determine song length?

18:55:09preglowthen pressed back until i was at the previous track

19:40:12preglowCoCoLUS: exactly

19:45:37stripwax_amiconn - oh, good find

19:58:50]RowaN[oh, but you knew that
19:59:33linuxstbIt seems that Ogg doesn't actually store the total length of the track anywhere - you need to seek around the file and calculate it...

20:25:30Nuxatorif you click one song to play it it plays
20:26:09Nuxatorthen click again to choose another file :buffering start but play stop and then player return to file list
20:26:40Nuxatorcan someone test to see if it's confirmed
20:26:51linuxstbAre you using the very latest bleeding edge build?
20:27:02Nuxatorno
20:27:26Nuxator19h41 version
20:27:36SlasheriThat problem is fixed in the bleeding edge build
20:27:55preglowif you're going to report a bug on audio playback, always download the latest build first
20:28:07preglowthings are moving fast
20:28:12Nuxatorbut i dl it 30 min ago
20:28:39Slasherihmm, bleeding edge?
20:28:50Nuxatoryes
20:29:08Nuxatorjust a minute i'll test the lates one
20:29:08Slasheriinteresting.. it should not have that bug anymore
20:29:12linuxstbI can't see a 19h41 version on the website

20:29:45Slasheripreglow: no, just try to keep them below 32 kB
20:29:51preglowyeah, sure
20:29:59preglowi've almost got gapless playback here
20:30:06preglowbut something is just a wee bit off
20:30:06Slasherioh, great :)
20:30:53preglowi wish audacity could read raw pcm
20:30:53preglowarghh
20:31:05Slasheritry hexedit :)
20:31:06CoCoLUSwhich codec? ac3?
20:31:37Nuxatorok bug was fixed
20:31:40linuxstbpreglow: Just use "sox"
20:32:17preglowi also wish audacity was actually usable
20:32:19preglowgod, how i hate it
20:32:21preglowi loathe it
20:33:13linuxstbDoes anyone know if any of the Windows audio editors work with Wine? I tried installing Adobe Audition, but it wouldn't work.
20:33:37linuxstbI couldn't get cdwave to work either.
20:33:58Nuxatorhummm
20:34:30preglowaudition works poorly in wine
20:34:35preglowoh, how i misses it
20:35:42Nuxatorok the bug is still here
20:35:46Nuxatormore tricky
20:36:09Nuxatoryou have to change song before hd spin down from first 2mo buffering
20:38:12linuxstbWhat kind of files are you using? I can't get it to crash with FLAC or Vorbis
20:38:16Nuxatormp3
20:38:29Nuxatori'll try with ogg
20:38:37Nuxatorbut it doesn't occur all time
20:38:48Nuxatorhave to click on several track
20:39:06Nuxatorbut when it occurs it's for each track until reboot
20:39:36preglowhmm, the start of the waveform wobbles like hell
20:39:44preglowthat's to be expected, i suppose
20:40:30Nuxatorgot it too with oggs
20:41:18Nuxatormaybe initial bffering when interupted doen't free mem
20:41:41Nuxatorand if you switch several tracks it shows this bug
20:41:50preglowhmm
20:41:58preglowit actually looks like i have managed gapless playback

20:49:54Nuxator^^
20:51:05preglowSlasheri: when i pasted first.pcm and second.pcm together in audacity, it sounded a bit smoother than the track change did on rockbox
20:52:18SlasheriHmm
20:52:47Slasherimaybe audacity did some filtering
20:52:52preglowsincerely doubt it
20:53:00preglowthere's still a glitch
20:53:07preglowbut i believe that's from the distortion in the waveform
20:53:40preglowbut ogg vorbis transitions are completely smooth
20:53:45preglowso can't be rockbox code
20:53:47Slasheripreglow: You should also try not to reinitialize the codec between track-change
20:54:04Slasheri(put next_track: label after all initialization stuff)
20:54:22preglowdoes this matter mpeg audio?

21:18:56preglowthere some sample lying around unaccounted for

21:19:26preglownow, even
21:19:56yngwicocolus, i also have sometimes problems with next artist /title, but it seems its rather a problem with buffering or so (?) because if I wait long enough (somtimes more than a half song) the next playing usually shows up

21:22:44CoCoLUSslasheri, you stopped the buffering of the next track from happening until 20 seconds of the first file are played, right?
21:22:46Slasherihmm, maybe not..
21:22:53preglowSlasheri: anything that might benefit gapless? :>
21:23:00SlasheriCoCoLUS: no, after 2 MiB are buffered

21:23:13preglowoh well
21:23:17preglowi'm gone for a while
21:23:29CoCoLUSmaybe that's the reason for the next artist/track info not being available?
21:24:26SlasheriCoCoLUS: yes, that's the reason
21:24:39Slasheriwill be fixed later :)
21:24:42CoCoLUSi see
21:25:22CoCoLUShm how do you think you'll fix it? either the next file is loaded or it's not, so how would it be possible to retrieve the next-info...
21:26:51Slasherimetadata of next track can be loaded without buffering the track itself
21:27:01linuxstbCoCoLUS: The meta-data can be read from the file directly from disk, without it being buffered first. I don't know if that's how we'll do it though.
21:27:28linuxstbWe are thinking alike then...
21:27:33Slasheri:)
21:27:51linuxstbI thought that was what was happening now.
21:29:06linuxstbOgg files are a pain to parse though. I may need to borrow some code from Tremor to do it.

22:11:29linuxstbAnyone fancy converting the parse-ogg.lisp function that markun found into C? I think I've had enough of ogg.
22:13:45markunWhere is the spdif encoding done in the iriver?
22:14:52markunI wonder if we can send a 'new track' signal so minidisc will split the tracks during recording
22:15:05preglow'course we can
22:15:13preglowjust find out how
22:16:12 Quit bipak (Read error: 60 (Operation timed out))
22:16:39markunI thought the optical diode would be connected to the uda1380, but I can't find anything about spdif in the datasheet.
22:20:46[solid]hmmm weird... seems something happened with rockbox while i was out
22:21:04[solid]it's showing only 45 minutes of runtime and the battery is quite fool... weird
22:21:11[solid]and it turned off
22:21:36[solid]recharging and repeating the vorbis test, with wps info this time :)
22:22:51SlasheriI located one new crashing issue. It's caused by pcm_play_pause -function
22:22:51HCl"capabiliteys"
22:22:52HClXD
22:23:00HClthey should learn how to spell on misticriver
22:23:01HCl"kernal"
22:23:02HClXD
22:23:05SlasheriThat gives the I04: xxx
22:23:09Slasheri:D
22:23:32preglowHCl: plzz, it's called kernal if it's on a c64 :P
22:23:43HClxP
22:26:37LinusNmarkun: the s/pdif is connected directly to the cpu
22:27:19markunLinusN: thanks, then I will look in the coldfire manual again
22:28:35*LinusN should complete the schematics
22:28:59[solid]"First version of Musepack playback (not working)" - what does 'not working' mean here?:)
22:29:44[solid]not realtime or disabled on purpose?
22:30:20preglow[solid]: it's just barely realtime
22:30:27preglow[solid]: and the codec plugin isn't working
22:30:42preglowkudos to the musepack people for making my work in optimising it hard
22:32:04preglowthe ac3 codec was a nice break from that ;)
22:32:10[solid]:)
22:32:34[solid]so it basically means it won't play any .mpc at the moment, realtime or not, right?
22:33:53preglowcorrect
22:34:40LinusNgotta go, cu later

22:47:48yngwiwow, this iriver battery is awesome, playing for 12 hours now (with orig. fw) and still two bars left... when is it gonna end
22:48:52markunAh, I found it! If we change the tracknumber in the cd-subcode that can be send in the spdif packets the minidisk will insert a new track mark.
22:49:18markunNow I just have to borrow a minidisc player..
22:49:27SlasheriNow started new battery test (128k CBR MP3, 50% volume, no cross-fade, 12 tracks with suffle & repeat)
22:49:30Slasherinite :)
22:49:40markunSlasheri: good night
22:49:46bill2or3yngwi, which battery in which iRiver?
22:50:00yngwithis is going to be interesting, good night, slasheri
22:50:13yngwibill2or3: the standard one..
22:51:03bill2or3which iRiver?
22:51:32yngwih140, 11 days old :-)
22:51:54bill2or3ahh. I just ordered an H340
22:52:29preglowoooh, sufflé and repeat
22:52:46yngwii bought the h140 mainly because rockbox :-) (and 'couse i don't care for fancy colour lcd displays and stuff.. :-) )
22:53:17bill2or3yeah, I'm hoping rockbox ends up getting ported
22:53:39yngwii'm sure it will...
22:54:13bill2or3someone added them to the DeviceChart in the wiki, that's a good sign
22:54:23yngwibut i was very impatient
22:54:36yngwithere is even a forum for h3xx
22:55:05yngwiwhich is a good sign too
22:55:08yngwi:-)
22:57:05bill2or3yep
22:58:13preglowperhaps it's time to remove the wav player in the debug menu? :>

23:01:36 Quit DomZ ("CGI:IRC")
23:12:40preglowlike i suspected
23:13:13preglowmp3 might be gapless, but it will never be glitchless for all inputs
23:14:53HClwhy not?
23:17:22preglowbecause the waveforms rings like a bell in the crossover
23:17:25preglowwaveform
23:17:40HClwha?

23:29:44markunDoes it sound very bad?
23:31:04preglowyou can hear it
23:31:10preglowbut it's not a very probable scenario
23:31:14preglowi very seldom listen to sines ;)
23:31:36markunsurfing on sine waves :)
23:31:44preglowhaha
23:31:50preglowthere's very few sine waves in that, actaully
23:31:51preglowbut nice album
23:32:53markunIt would be fun to insert the tracknames in the spdif stream, but I doubt there will be many people who use it..
23:33:05preglowhey, why not
23:33:09preglowif you find out how, do it
23:34:22markunYes, I found it more or less.
23:35:27markunBut I don't have a minidisc player. A friend has one, but I don't think it can display the cd-text.
23:35:34preglowmine can
23:36:57***Saving seen data "./dancer.seen"
23:37:36markunYou can insert cd-subcode in the spdif stream, MCF5249UM.pdf (page 300)
23:38:10markunDoes the minidisc save the original tracknumber of the track?
23:38:17 Quit niobos_study ("off to bed")
23:38:34preglowsincerely doubt it
23:39:33Stryke`preglow: how does it sound decoded by foobar?
23:39:33markunthat's good, because the mindisc starts a new track marker when tracknumber changes. We can flip it between 1 and 2 on track change or something..
23:39:55preglowStryke`: that _is_ foobars output :)
23:40:01Stryke`oh, heh
23:40:20Stryke`if rockbox's output == foobar's output, NO ONE will complain about gapless
23:41:15preglowthen you don't need to worry about that, 'cause foobar source code is how i found out how to do it
23:41:36thegeek_preglow: I doubt anyone would expect gapless to mean acutally transparently crossfading/syncing the sinewaves in the two tracks ;)
23:41:36Stryke`excellent =D
23:41:47preglowthegeek_: vorbis manages it :P
23:41:52thegeek_damn
23:41:57thegeek_I'm impressed;)
23:42:02preglowthegeek_: but no, it _is_ unreasonable for a subband codec
23:42:12thegeek_mhm
23:42:48webguest65perfectionist indeed :)
23:43:15Stryke`i thought MPC was the only major subband codec and that MP3 and Vorbis were transform codecs
23:43:25preglowStryke`: mp3 is a hybrid
23:43:55Stryke`so decoded MPC should suffer from the same glitchiness?
23:44:04preglowi believe it will
23:44:07preglowbut hey
23:44:08preglowit's a sine
23:44:13preglowdon't worry :P
23:44:47Stryke`ok
23:51:49preglowi do wonder why my gapless playback isn't perfect, though
