00:31:10*TheSeven wonders how to figure out why playback needs so much processing power
00:32:59saratogahow much does it need?
00:33:19TheSevenit doesn't even play back WAV files (containing cd-quality PCM) without stuttering
00:33:33TheSevenFLAC, however, works nicely (but seems to need almost 200MHz)
00:33:52saratogaWAV is faster then flac so its probably not the codec itself
00:33:57saratogadisk driver maybe?
00:34:19TheSeventhat fun goes on after it completes buffering, so it can't be the disk driver
00:34:33TheSevenMP3 stutters as well
00:34:36saratogahow big is your audio buffer?
00:34:48saratogacompressed audio?
00:35:01saratogaand do you have cache enabled?
00:35:11 Quit Rob2222 (Quit: Rob2222)
00:35:21TheSeventhe PCM buffer is ~500KB, the compressed audio buffer ~60MB
00:35:27TheSevenand yes, the caches are enabled
00:35:35TheSeventhe test_codec results look sane
00:35:43saratogahow fast for MP3?
00:35:48TheSeven(WAV needing 2.5MHz, FLAC like 20MHz, MP3 like 45MHz)
00:36:03saratogathis is on arm9E?
00:36:14TheSevenyes, running at 216 MHz as far as i can tell
00:36:25saratogathats quite slow compared to AMS
00:36:34TheSeven(some quick measurements showed ~190MHz, so that should be right)
00:36:49TheSevenmemory bandwidth is >100MB/s, so that's not an issue either
00:36:58*TheSeven thinks the only thing left is the PCM buffer
00:37:22TheSevenPCM driver*
00:37:30saratogatest_codec doesn't yeild IIRC
00:37:36saratogaplayback does
00:37:59saratogamaybe some issue with scheduling?
00:38:35TheSevenbuffering seems to be over-yielding (in the ATA driver), but apart from that I can't see what might be going on
00:38:41saratogaif you open up mpa.c or some similar codec and make it yield less often does the stuttering get better?
00:38:49TheSevenisn't it basically only the codec thread that's eating CPU power once buffering has finished?
00:39:06saratogaassuming the screen is off i think so
00:39:16 Quit mystica555 (Ping timeout: 240 seconds)
00:39:35saratogaalthough i guess its possible you could have something busy waiting in a driver or something by mistake
00:39:35TheSevenWPS or sitting in the main menu (cabbiev2) doesn't make a difference
00:39:42froggymanis there any reason why volume control on the fuze seems to take a while to initiate? The new volume that the person sets doesn't seem to take effect till a couple seconds after you change it
00:39:49TheSeventhe UI is almost unresponsive
00:39:56TheSeven(except for FLAC)
00:40:08saratogayeah that'll happen if the PCM buffer gets low
00:40:20saratogait'll starve the GUI first

00:41:59saratogatest codec fakes most of the playback and buffering APIs, so its not unreasonable that it could be different, but i'm not sure how this could be a hardware specific issue
00:42:50TheSevenfor FLAC, the PCM buffer is always around half full full
00:42:57saratogaif you disable the audio driver (just have it discard samples) does that improve things?
00:43:14TheSevenand buffering and the codec seem to be fighting badly while buffering is still active
00:43:24TheSevenbuffering almost can't keep up with playback
00:43:24saratogai wonder if you're just getting spammed with interrupt requests
00:43:54TheSevenbut why does FLAC work if WAV doesn't?
00:44:05TheSevenare the PCM chunks insanely small for WAV?
00:44:28saratogai can't remember how libpcm does it
00:44:33saratogabut they may be smaller
00:44:41saratogaa lot of codecs force larger PCM chunks then we'd like
00:44:44TheSeventhe PCM driver can handle up to ~9000 samples (which is the highest number i've seen so far in a single chunk) with a single IRQ
00:44:45saratogasince we want to yield often
00:45:29saratogamost codecs generate about 2048 samples at a time
00:45:36*TheSeven means 9000 samples per channel, so 18000 samples or 36KB total
00:45:42saratogawhich codec?
00:46:04TheSeveni think that was MP3 (which was the first one i was testing with)
00:46:27saratogaok then thats the DSP engine combining multiple frames

00:58:11n1sgevaerts: does the build master have a way to determine if the client uses the correct version of something?
00:58:52kugelwe just need a toolchain test which is a little more sophisticated than which
00:59:01gevaertsIt just checks if it finds the compilers
01:00:07saratogaTheSeven: my wav files generate about 100 samples at a time, which is significantly less then most other formats I suspect
01:00:21kugelI don't think we need to worry though
01:00:44CIA-7New commit by theseven (r28982): iPod Classic: Unmute amplifiers when setting volume (fixes resuming paused playback)
01:00:46n1sunless we need it to be super smooth i'd say 1) commit configure/ changes and send mail to client owners 2) disable all cf builds 3) reenable for people who have updated
01:01:02gevaerts2) isn't really needed
01:01:10kugelwe would probably add a new m68k-elf-gcc452 target (instead of only m68k) and trust people that have it in their
01:01:13gevaertsWe can do a different architecture string in the clients
01:01:22gevaerts(as kugel said)
01:01:52n1swouldn't the only difference be a different error?
01:01:53CIA-7r28982 build result: All green
01:01:57gevaertsAnd yes, as far as I remember the plan is to do that
01:02:51gevaertsn1s: no. If a build client announces "m68k", it won't get builds that require "m68k-elf-gcc452"
01:03:47gevaertsThe *only* problem is that this list of announced architectures is hand-built by the build client maintainers, so there's some room for human error there
01:04:22n1sok, so should we keep the option to build the old toolchain in ?
01:05:57gevaertsI think we should somehow have the clients report compiler (and binutils?) versions to the server automatically
01:06:17n1syes, that would be good
01:06:29gevaertsSo when the client admin specifies "m68k-elf-gcc", the script expands that to m68k-elf-gcc452 or m68k-elf-gcc346
01:07:02n1sand the server should be able to decide on version requirements per-build as a sim build for example doesn't have such stric requirements
01:07:31 Join panni_ [0] (
01:07:32n1sanyway, i'll look into adding the suffix to the script tomorrow
01:07:35gevaertsThat does complicate things a bit...
01:07:48n1sthen we can probably start the transition
01:07:52JdGordon1isnt the sim a completly different beast in the build system?
01:08:04gevaertshm, yes, it is
01:08:14gevaertsWell, yes and no
01:08:25gevaertsn1s: I meant doing that in the build client script
01:08:33gevaertsNot necessarily in
01:08:55n1sgevaerts: ok, then i'm not really following :)
01:09:00kugeln1s: i don't think we need the old toolchain around

01:10:19n1skugel: i'd like to get rid of it too, only someone should keep one to do an eventual 3.7.2 release
01:10:26kugelwe only kept the old arm toolchain because it was a) easy and b) not all targets where tested when the transition happened
01:10:46n1sgevaerts: well, i'm not very used to it but have hacked a few of our lang scripts
01:10:47gevaertsright. We don't want to change toolchains for the stable branch
01:11:25gevaertsBut the stable branch will still have its own, so it's always easy to build a toolchain for it
01:11:54gevaertsn1s: I think we should wait for Zagor to appear before doing this. He knows how these scripts work :)
01:12:17n1syeah, any idea when he'll be back?

01:15:09 Join eRivas [0] (
01:15:20gevaertsn1s: anyway, the script has a bit where it checks that every arch specified with -archlist has a matching compiler. That check could presumably expand the arch string to append versions
01:16:16gevaertshm, actually...
01:17:36gevaertsIt now does "which m68k-elf-gcc", but somehow the gcc build also produces "m68k-elf-gcc-3.4.6" (and similar for the others). That means that the client script could check for the right compiler version (not binutils unfortunately, but that's probably minor)
01:17:51gevaertsSo all we have to do is update and push a new version
01:18:21gevaertsPushing a new version has to be done by a server admin, so we need one of the (other :) Swedes for that
01:19:30n1syes, clever. While i might be able to do that i'm not comfortable coding things i can't test :)
01:20:16gevaertsAt the same time, when we transition to 4.5, we change the announced string to also have the version (like it's done for eabi). That way (as long as there's only one toolchain in the path), there's a cross-check between what the client admin configures and what's actually there

01:25:23n1ssounds great
01:25:29gevaertsAs long as we have a few when we switch (but not all yet, otherwise unexpected commits from just before the switch wouldn't build), we're fine

12:02:13max131damnit, i've got a file system corruption again on the fuze-v1. I'm running r28979 now, but i had a 'delayed write failed' error in windows xp. So the USB stack is not as solid as i expected??
12:03:09max131this time around i was moving nearly 1G of files from the hard disk to the internal memory of the fuze, _not_ to the uSD
12:04:35max131after the delayed write failed, the fuze locks up entirely, the only thing i can do is a 'hard reset', i.e. keeping the slider on the right of the fuze up for more than 10 seconds
12:05:04n1sthat sounds just like the recent sd issues

13:05:16TheSeveni don't think anything besides the clickwheel acceleration (and the profiling code i just added) uses it
13:06:10n1sah, so another timer is used for ticks?
13:07:16wodzWhat about system ticks? Are you sure it works as advertised? I had various strange effects on HD200 when tick was much longer due to bug in timer configuration

13:26:56TheSevenand no, it didn't fix playback
13:27:34TheSeveni did some IRQ load profiling which ended up at 5 milliseconds of time in the PCM IRQ handler over like a minute of playback
13:27:38TheSevenso that's not the cause either

13:46:52linuxstbyes to which question?
13:47:14TheSevenit will be flashed to NOR and the HDD will be reformatted, as apple seems to be doing something funky that's preventing us from mounting it
13:47:32linuxstbWell, that's nice of them...
13:47:55TheSevenmight be related to them hiding away the firmware partition and thus offsetting things

14:14:50TheSevenno, i didn't try that yet.
14:14:58TheSevenhow should such a thing behave?
14:15:12TheSevenregister a tick function that calls the PCM get more callback?
14:15:24n1si don't know exactly
14:18:04TheSevenhm, might pcm_get_bytes_waiting returning very funky values be the cause?
14:20:54TheSevenit actually seems to be pcm_get_bytes_waiting that's eating the cpu cycles

14:22:18TheSevenno, i have absolutely no clue why it happens, but i have proof that this function is going nuts
14:23:05n1sthe codec thread seems to use that function to determine the elapsed time so i'd guess wrong values would confuse it
14:23:19Buschelwell, the implementation for S5L8702 is the only that has a while-loop inside

15:07:48TheSevenhm, three seconds is the length of the PCM buffer
15:09:57TheSevenBuschel: it would cause the playback progessbar to jump around, and the only reason why it wouldn't cause playback corruption is the lacking support for pcm double buffering in the pcmbuf code

18:39:58n1sif you have foobar2k there's some feature to "optimize" the layout of the files that might help

18:58:52pixelmaisn't it in the hardware present section?
18:59:25LambdaCalculus37TheSeven: Adjusting the sound controls affects the output volume. I'm trying to raise up the bass on my Classic in the sound setting menu and it nearly blew my brains out.
18:59:26TheSevenLambdaCalculus37: it was a matter of adjusting some rather insane ifdef
19:00:06TheSevenhm, interesting
19:00:24TheSevenapparently enabling the DSP increases the volume
19:00:59TheSevenhm, or it's just some reg mixup
19:01:01pixelma[Saint]: Time & Date was a bit silly for the targets that do not have an RTC - this section was only enabled for this one tag and I guess that was confusing too

19:07:06TheSevenLambdaCalculus37: it's still a mystery how FLAC could work before that fix
19:07:19saratogaLlorean, n1s: (catching up on logs) IIRC the foobar optimize function shouldn't be needed anymore for M4A files
19:07:41saratogaalthough theres basically no chance of a 2 hour AAC file playing anyway
19:07:43TheSeventhat bug made that "get remaining bytes" function loop until the pcm buffer was almost empty
19:08:01saratogaah, makes sense why testcodec worked fine then!
19:08:17saratogai'm curious though, i saw you fixed the timer, does that mean your test_codec results were inaccurate?
19:08:34TheSevenif they depend on the tick timer, probably yes
19:08:43Lloreansaratoga: Is there some reason we can handle arbitrary lengths of most formats, but not AAC?
19:08:47TheSevendivide the MHz numbers by ~1.6 in that case :)
19:08:53 Quit Topy (Read error: Connection reset by peer)
19:08:54LloreanIs it a format limitation, or just something "not finished yet" in Rockbox?
19:08:58saratogai expect them to be wrong, but i'm not sure about the timmer
19:09:13*TheSeven might do a full codec test tonight
19:09:26saratogaLlorean: yeah because the mp4 spec is a mess and the spec isn't free either, so i'm not sure what the "right" fix is to long files
19:09:33TheSevenit would be nice if test_codec would use the usec timer for that
19:09:54saratogai can hack it up so that long files play (at least from apple) but i have no idea if the parser is even correct at that point
19:10:34saratogaright now we use a look up table to keep track of where individual mp4 frames are in the bit stream, but if the file is more then 45 minutes long you run out of ram to store the lookup table
19:11:19saratogaTheSeven: if those memory results are right then I expect you to be quite a bit faster then AMSv2, which could do flac in under 10MHz
19:12:32sbmullgevaerts: looks like FS #8852 has been closed.
19:12:34Lloreansaratoga: Might it make sense to take your "hacked up"version and put it in the 'official test builds' section and see if anyone can find files it doesn't like?

19:12:45*TheSeven would really like to know how fast the nano4g would be
19:12:55gevaertssbmull: yes, because we don't plan to commit that without any code that uses it
19:13:14TheSeventhese little things might well outperform the beast
19:13:17saratogayes, thats on my todo list, just pretty far back since no one uses aac all that much
19:14:18LloreanAAC-HE seems to be pretty popular for audiobooks performing pretty well at low bitrates.
19:14:31*LambdaCalculus37 sees that the nano3G and the Classic1G are not quite as similar hardware-wise as he was initially thinking
19:15:11TheSevenLambdaCalculus37: different PMU, different codec, different RAM
19:15:20TheSevenapart from that, they should be fairly similar

19:19:50saratogai was thinking something like that for the IEEE student magazine might be nice, they've done them in the past on open source firmware for cameras, and IEEE readers are quite likely to be interested in firmware hacking verses normal people
19:20:14saratogatowolf: 14 bit ADC would be my guess
19:21:01towolfsaratoga, so 2 bits of headroom are lost? is this normal?
19:21:23saratogatowolf: you mean compared to a 16 bit ADC?
19:21:48towolf... that these little devices don't record at full level
19:21:55LambdaCalculus37TheSeven: The only other DAP I saw in this store was a nano5G, but I know that's totally out of the loop right now. Not a shred of custom code for it.
19:21:56towolfs/level/bit depth
19:23:18saratogatowolf: we should probably automatically increase the volume of the output file by 2 bits, but otherwise yes thats normal
19:24:00*GodEater updates said page.
19:24:26towolfsaratoga, ok, thank you. i was wondering about this. who knew that lower bit depth would manifest in lower volume. but it makes sense. once normalized it will have reduces resolution.

20:16:09Buschel[Saint]: it has been committed already. you've mentioned this tearing some days ago (when CPU is boosted)
20:16:10towolfsaratoga, regarding the 14-bit to 16-bit issue. do i understand right that i just need to bit-shift by 2? are you aware of any tools that do this?
20:16:59[Saint]Buschel: Um...what has been committed already?
20:17:05[Saint]and, when?
20:17:37Buschel[Saint]: all available LCD optimizations (except some YUV stuff which is not relevant for the tearing you described)
20:17:53towolfi further assume that a standard normalization would achieve almost the same thing but would introduce minor rounding errors? so a bit-shift would be simpler and cleaner?
20:18:55*[Saint] wonders why he didn't get any conflicts when he updated his SVN checkout.
20:19:11Buschel[Saint]: maybe because the changes were identical
20:19:23[Saint]Ah, possibly.
20:19:30gevaertstowolf: is the quality of that microphone really good enough for these possible rounding errors to matter?
20:20:54towolfgevaerts, not really, but in normalization it maximizes according to the single maximum peak sample
20:21:42towolfthat is probably the main issue. i just need to multiply the sample values by 4. as far as i understood things correctly. right?

20:34:48n1shmm, not a great fit if i understand the capablities of your codec
20:35:48TheSeveni can basically set the corner frequency and gain of a bass and a treble shelving filter
20:35:48n1sTheSeven: are those frequencies cutoff freqs for bass and treble filters?
20:35:58n1sah, ok
20:36:22n1sso just popping in 2 extra settings for that would be simpler i think
20:36:23TheSeventhe gain is handled in a sensible way already, just not the corner frequency
20:36:46TheSeventhe problem with this is that those settings have non-linearly distributed target-dependent values
20:37:13TheSevenwhat would you recommend as default values for them?

21:53:44TheSevenwhat the hell.
21:54:29TheSeveneven if i make the audiohw_set_bass/treble functions do nothing, the volume increases greatly when increasing the bass/treble value in the sound settings menu above 0dB
21:55:31Buschelsaratoga: updated FS #11858
21:55:32jhMikeSsounds logical

21:56:00[Saint]One word: "Apple"
21:56:39kugelTheSeven: is the software bass/treble running?
21:56:45TheSevenno idea
21:57:05TheSeveneven if it would be, that kind of thing certainly shouldn't happen
21:57:45kugelnear 0db it works by making all other frequencies quiter, to avoid clipping
21:57:51jhMikeSTheSeven: I'd expect it to get quieter or not change at all
21:57:57Buschelcan r28877 lead to lockups on dual core engines?
21:58:24kugel(if you raise bass/treble, that is)
21:59:12TheSevenoh, I think I know what might be going on
21:59:33TheSeveni have 1.5dB gain steps for that
21:59:35jhMikeSBuschel: I would be very surprised it it would
21:59:59TheSevenand if i go to +1.5dB, it sounds like the volume went up by 15dB
22:00:09TheSevenis there something ignoring num_decimals?

22:01:40jhMikeSyou need the unscaled current_bass, current_treble
22:02:11jhMikeSif you're modelling this after gigabeat F's way
22:02:18TheSevenhow does this work with hardware bass/treble?
22:02:35TheSevenare things attenuated in software to prevent clipping in the codec's DSP?
22:02:54jhMikeSit's in tenth-db's already, so the anti-clipping attenuation doesn't need the "*10"
22:03:05jhMikeSTheSeven: indeed
22:03:18jhMikeSsort of
22:03:45jhMikeSif the hardware can prescale the volume somehow, the hw does it. if it's SW tone controls, the DSP does it
22:03:52TheSevenhm, i should probably implement hardware pre-cut then
22:04:47jhMikeSit scales the volume down by the band with the highest posive gain, or else leaves it alone if none have + gain
22:05:05BuscheljhMikeS: any idea what could cause FS #11863 ? this definately came in before the ATA changes
22:06:13TheSevenjhMikeS: so it basically scales it down in pre-cut, then applies bass/treble, and then scales it up again in the amp
22:06:36TheSeven(and scales it up by an order of magnitude too much on the classic)
22:06:46TheSevenis that upscaling also effective for lineout?
22:07:28 Join Keripo [0] (
22:08:09jhMikeSTheSeven: it should be effective but I suppose that depends on the codec itself and its setup
22:08:42TheSeveni've seen a bunch of hardwared 0dB's for lineout in sound.c, which will probably interfere with that
22:08:44jhMikeSBuschel: I haven't seen any issues myself on my targets.
22:09:37jhMikeSTheSeven: on the targets I implemented, I used DAC volume as a precut which doesn't affect any analog stuff. I don't know if you can do that there.
22:10:08TheSeveni can actually do that in two places
22:10:25 Join max131 [0] (
22:10:27jhMikeSBuschel: I'll think about it but nothing obvious strikes me
22:10:37TheSeventhere's a prescaler in the dsp, and another one after the mixer, before the tone control
22:10:54TheSeven page 26
22:11:13BuscheljhMikeS: that would be helpful. maybe you get an idea...
22:11:45jhMikeSBuschel: They mention mpegplayer which shouldn't be affected by priority changes by the pcm buffer that don't happen when it's running
22:11:51TheSeveni'll probably use MSTxVOL for that, so that one can apply a pre-cut even if the DSP is powered off
22:13:23BuscheljhMikeS: also test_codec did not load today when I experienced this. there is no clear image about what is happening in detail...
22:15:02max131so i suffered from an fs-corruption again during past day, and i'm running r28979 now
22:15:09BuscheljhMikeS: for now it did only happen for soap (iPod nano 1g) and me (iPod Video). I did not happen on my iPod nano 2g yet. that's why I am guessing it might be connected to dualcore. or maybe some ATA DMA stuff
22:15:34max131that's on a fuze-v1, anybody else seeing this issue occasionally?
22:16:26B4gderfront page updated
22:16:47jhMikeSTheSeven: PMIXxVOL?
22:18:27max131i'd like to help and pinpoint where the problem is, but i'm not a coder, and i would like to get the fuze more stable
22:18:33TheSeventhat's only available if the DSP is powered on and has a smaller range
22:18:46TheSevenand from a clipping point of view MSTxVOL is early enough
22:19:19TheSevenand, as the tone controls are effective for all signal sources, i'd say the precut should be as well
22:19:59max131i thought the whole issue started with r28834, but apparently the fs-corruption re-occured this morning, after having the storage formatted using the original firmware
22:20:35jhMikeSBuschel: I've played my H10, e200 and 3g without issues

22:33:25TheSeven"The codecs listed use HW tone controls but don't have suitable prescaler functionality, so we let the prescaler stay at 0 for these, unless SW tone controls are in use. This is to avoid needing the SW DSP just for the prescaling." - now what the hell is that meant to tell me?
22:34:12TheSevenit doesn't seem to match the code on the first glance, as it's an exclusion, not inclusion, list
22:34:40max131gevaerts: ok, thanks
22:35:08TheSevendo codecs that use hardware tone controls define HAVE_SW_TONE_CONTROLS?
22:35:19TheSevenapparently they do, judging from that code
22:35:25CIA-7r28998 build result: All green
22:37:15jhMikeSTheSeven: I'm not sure what this "suitable prescaler functionality" is. Sometimes it needs to be manually calculated but the hw can still prescale.
22:40:06jhMikeSex: if wm8721 has tone controls off, then it shouldn't call prescaler code, since it doesn't need it without tone controls
22:40:23jhMikeSit doesn't have it's own anyway

22:44:15leavittxhi! i run a simulator of cowon d2 (also tried x5 - same thing) and get segfault when i choose for example plugins->games->xobox and then Properties. this is strace output:

22:54:35bluebrotheranyone familiar with perl and can have a look at
22:54:51leavittxwhat generally could be a reason of simulator segfault?
22:55:23TheSevengdb will tell you :)

22:57:27CIA-7New commit by wodz (r28999): Add thumbnail for HD300
22:58:14wodzTheSeven: this string is not defined in lang file for this target
22:58:23TheSevenyeah, but why?
22:59:15*bluebrother wonders if he should just commit this. But: do I need to update the revision number?
22:59:32wodzB4gder: ping
22:59:39jhMikeSThat string might not be using features properly
22:59:50leavittxTheSeven: i don't believe that only i have this segfault... at least my friend have it too
22:59:53B4gderI'm here
23:00:41jhMikeSnope, only defined for ipodvideo
23:00:44wodzB4gder: May I ask for www update?
23:00:45gevaertsbluebrother: that's probably best
23:00:53TheSevenjhMikeS: where do i need to change that?
23:00:57bluebrotherB4gder: do I need to change the revision number when changing to fix cpu core number detection on OS X?
23:01:10TheSevenB4gder: do you happen to know where Zagor is hiding or when he'll be back?
23:01:13B4gderwodz: sure, done!
23:01:17wodzB4gder: I just commited thumbnail for HD300 (thanks to perfectdrug's work)
23:01:21bluebrother(see −− any comments on that? I'm not that much familiar with perl, but it works for me :)
23:01:27gevaertsbluebrother: if you don't change it, existing clients can't be told to upgrade
23:01:31B4gderbluebrother: if you want all clients to upgrade, then yes
23:01:56wodzB4gder: thx
23:01:56 Quit max131 (Quit: CGI:IRC (EOF))
23:02:13bluebrothergevaerts: sure, but do I want that? It's only relevant for OS X, and since the number of cores gets reported as 0 right now on OS X it doesn't work anyway.
23:02:19B4gderTheSeven: yes I do know where he is physically but I can't tell when he'll be around in here
23:02:44jhMikeSTheSeven: or apps/features.txt if you want fix the feature part
23:02:48bluebrotherhmm, maybe it's best to bump the revision number, wait for clients to update and see if I brok the build system :)
23:03:00perfectdrugwodz: thanks ( B4gder too) do you commit the manual part aswell?
23:03:39wodzperfectdrug: When I start work on manual for HD300 I'll commit this

23:12:28bluebrotherhmm, if I want the build clients to update I also need to bump $minimumversion in, right?
23:13:38gevaertsYes. I'm not sure if it's a good idea for anyone but a server admin to actually do that though
23:14:09bluebrotherhmm. I guess I'll keep the current revision number then.
23:14:50bluebrothersince that change isn't required by any client running on linux. And anyone setting up a client on OS X should (hopefully) get the most recent scripts from SVN anyway.
23:16:48BuscheljhMikeS: a question -> what happens if the codec thread gets higher priority as the buffering thread, if rebuffering is occuring?
23:18:31 Quit Keripo (Quit: Leaving.)
23:18:37jhMikeSBuschel: It would cause codec to be preferred over buffering if both have to run, but if the codec is waiting for buffering, the buffering thread will run
23:21:15 Quit perfectdrug (Quit: Leaving.)
23:22:00jhMikeSit would only be a problem if the codec can't regain ground and fill the PCM buffer. if it can't, then CPU resources are being overtapped

23:45:12TheSevenjhMikeS: hm, the prescaler thing doesn't seem to work quite right
23:45:21TheSevenstarting at bass +3dB i get quite noticable clipping
23:45:39TheSeventhe overall volume is constant now though
23:49:19TheSevenif i don't offer a hw prescaler, things seem to be a bit better, but there's still noticable clipping at +6dB
23:51:41jhMikeSI'd be hard pressed to know why for your codec, I've only integrated that for wolfons. double-check scaling of db units?

23:57:31TheSevenjhMikeS: is my assumption correct, that it *will* use the software DSP, even if it needs it just for precut gain? (in contrast to the comment, which seems to be referring to compiling it in, not using it)
