02:18:17Unhelpfulsaratoga: any code that's currently in control of the UI will call get_action to get the next action, also passing a context. contexts can inherit other contexts, so what a selected context actually contains in terms of button mappings can be a bit complicated
02:18:51saratogai'm just trying to find the functions that link button presses to actual changes of state in the playback engine
02:20:49Unhelpfulright, and that's where things get messy, becaue whatever has control of the UI at present decides how to interpret buttons, by selecting a context which maps button events to action, and then in code that acts on the received action.

03:05:21 Join ischeria1 [0] (
03:05:34Blue_DudeThat could be driven by calls to functions in audio.h. Should work for hwcodec and swcodec targets.
03:06:26Blue_DudeIIRC the plugin API exposes them also.
03:09:01 Quit ischeriad (Ping timeout: 265 seconds)
03:11:40saratogaBlue_Dude: what is AUDIO_SRC_PLAYBACK?
03:11:49saratogacan rockbox actually record it's own output?
03:15:03Blue_DudeLooking for that reference...
03:18:34 Join joeyg [0] (
03:19:26Blue_DudeOh OK. It distinguishes what source gets output to the hardware: playback, radio, or line in. I have no idea if it means the recording hardware can tap it as its going out.
03:20:34Blue_DudeMIC IN is another possibility.
03:21:04Blue_DudeBut that one may be recoding only. Depends on hardware.
03:21:50saratogahmm ok
03:21:50Blue_DudeSPDIF IN...
03:22:00saratogaso i'd have to add another way to dump PCM to disk
03:22:13saratogai wonder if kugel's work makes this any easier
03:22:16Blue_DudeI don't know if we can loopback to the recording hardware.
03:22:46Blue_DudeWell the sim already does this. Did you mean on the target?
03:23:08saratogasim is fine
03:23:23Blue_Dude./rockboxui −−debugaudio
03:23:28saratogahow does that work?
03:23:55Blue_DudeDumps the PCM output to disk as it's sent to the PCM driver.
03:24:15Blue_DudeMakes a .RAW file. Essentially a wav file without the header.
03:24:36saratogait does this at 1x speed or as fast as possible?
03:25:15 Join bieber [0] (
03:26:21Blue_DudeAt 1X speed. If you want to dump it all ASAP, use test_codec.
03:27:42saratogayeah but that doesn't use playback, so it doesn't test the actual playback code, only the codecs
03:27:44Blue_DudeTest_codec makes wav files, too, so you don't have to convert. OTOH, if you're testing the interface, −−debugaudio captures exactly what's being sent out.
03:28:34Blue_Dudetest_codec uses the playback chain as far as dsp. It doesn't actually try to output anything through the playback engine itself.
03:28:45saratogayeah i know i've worked a bunch on it
03:28:54Blue_DudeFor that, use the sim.
03:29:37Blue_DudeIs there a problem with the playback engine? Or are you trying to benchmark it somehow?
03:29:44saratogatheres a lot of problems with it
03:29:51saratogalots and lots of things can crash it
03:29:54Blue_DudeWell, yeah :)
03:30:47saratogaeven simple things like repeat mode often don't work correctly, and then theres low memory targets
03:31:27Blue_DudeI don't like how the buffering context switches before the track is played out...
03:32:00saratogaisn't that for things like crossfade where its needed?
03:32:59Blue_DudeNah. It just switches when the buffer is finished with it, not when it's actually played.
03:33:12Blue_DudeCrud. Got to go... Back in a while...
03:50:06***Saving seen data "./dancer.seen"
03:54:57Unhelpfulmaybe for debugging purposes the sim could run the PCM output at some multiple of realtime?

04:17:17Blue_DudeUnhelpful: That's a possibility. But that would involve essentially artificially overclocking all of Rockbox, wouldn't it? I don't know.
04:18:14saratogalabi assume you could just change whatever clock SDL is using
04:18:29 Join TheSeven [0] (~TheSeven@rockbox/developer/TheSeven)
04:18:39Blue_DudeMaybe just a modification of sound.c in rockboxui would serve. Instead of waiting for the SDL driver to request more samples, it could just bypass SDL and send output to disk via the debugaudio mechanism already there.
04:19:13saratogalabis the only limit on playback/buffering/codecs the rate at which the PCM buffer empties?
04:19:22Blue_DudeBut it would have to be patient enough to recognize when it's starving for samples vs just running out of samples at the end of playlist.
04:20:05Blue_DudeWell, there's the kernal timer as well.

04:22:24Blue_DudeYou can cut out the SDL code in sound.c and replace it with a delay function that clocks out samples at 2X, 4X or whatever. At some point you're probably going to starve a thread for data but I have no idea where it will break down first.
04:23:17Blue_DudeAnd the UI will be just plain weird.
04:23:45saratogalabwell the idea was to drive it via a script and then compare the PCM output or check for deadlocks
04:23:50saratogalabthe GUI isn't so important
04:24:02saratogalabdetecting deadlocks will be interesting
04:24:13Blue_DudeI think it would be fun.
04:26:29Blue_DudeOr you could rewrite playback and buffering and save us all the trouble...
04:26:46saratogalabonly if i can drop all features except playback and seeking
04:28:05saratogalabeventually it would be really useful to have some simple automated testing built into the build system
04:28:47saratogalabqueue a few tracks and just skip around them, seek, rebuffer, switch codecs, etc
04:29:03saratogalabthat way if someone breaks something its clear
04:31:26Blue_DudeA script engine is considerably more than "playback and seeking".
04:32:21saratogalabit could be as simple as a list of commands that are fired into the action code every X ticks
04:32:35saratogalabi think the scripting is easier then hacking rockbox to do it all
04:33:29Blue_DudeI wouldn't mind being able to seek across track boundaries.
04:35:05*Unhelpful sees problmes in changing the playback "speed" if you're trying to debug things that may be due to interactions between threads... :/
04:36:20saratogalabthreading isn't the same in the sim anyway, so it won't be like on target
04:37:49Unhelpfuli thought we used locks to make the sim threads *seem* cooperative despite their being platform threads?
04:39:03saratogalabtiming won't be the same though, so if theres threading bugs they won't be the same
04:39:35saratogalabplayback bugs on the clip where nondeterministic on the device, so I assume timing was a factor
04:40:26saratogalabbut pcs are so fast, and we have so many on the build system we could do each test 100 times a day and catch all the serious ones
04:43:29Unhelpfulif we could send test scripts to the build system to run on sims ;)

08:21:56amiconnRegarding tta - I think I know why the filter asm doesn't help much. Unlike the filters in libdemac and libffmpegflac, the libtta filter function doesn't loop over multiple samples, but is called once per sample
08:22:44amiconnThe C version is 'static inline', using asm the way ucchan did un-inlines the filter function

08:26:33JdGordonamiconn: I'm looking for a good way to know if recording has taken the buffer or not? in_recording_screen() doesnt sound good enough...
08:28:44jhMikeSJdGordon: it takes in the init, using audio_get_buffer
08:30:06jhMikeSmore specifically, pcmrec_init calls audio_get_recording_buffer
08:31:15JdGordonI found that, but It doesnt expliclty release it?
08:31:21 Join DerPapst [0] (
08:31:50JdGordonand while it has it the buffering thread is still active and will cause big problems if anything calls bufopen()
08:33:13JdGordonthis could also mean that me wanting to use the buffering.c code to store the radio art images is a bad idea?
08:35:04JdGordon has my hack to work around this.. send an event in pcmrec_init saying get out of the buffer, and one in pcmrec_close() saying the buffer is safe again, but I'm not sure that is the best
08:35:16jhMikeSno it doesn't "release" it. it just stops using it and playback grabs it back later
08:35:19JdGordonand that is swcodec only right?
08:35:35JdGordonyeah, which doesnt sound very safe
08:36:47JdGordoncould we change recording to actually open a handle requesting the whole buffer instead of just stealing it? that way any calls to bufopen() would fail because the buffer appears to be full...

11:06:34kugelwhat's the point of a font which contains only numbers?
11:06:36Lloreann1s: I seem to remember someone complaining that seeking in the current version of MPC is pretty bad (just slow) as well. It would be worth checking to see if that was introduced when MPC was updated to handle the new sv?
11:07:27fmlkugel: I thought the commit message did explain it. What do you not understand?
11:07:28n1sLlorean: yeah, i was going to test Buschel's patch to fix the slowness when i wanted to see how slow it was before
11:07:56jhMikeSn1s: isn't that the same deal with the ascodec sansa's as the beast?
11:08:00n1sgood news is that his patch fixed the slowness, i'll try to go back in history to see if i can spot anything
11:08:00Lloreann1s: I meant the flac/mpc crash might be around that time too? It seems like something that might've been noticed.
11:08:44n1sjhMikeS: eh, what's the same deal? :)
11:08:46Lloreanfml: Is there an indication for users that the font is unusable even as a basic font?
11:08:49kugelfml: I mean, a font takes several KB in ram no matter of how many glyphs it has got
11:08:55LloreanI'm not sure we should be including fonts that can't even render the menus in English.
11:09:16funmani can record on clipv1 and i only get warnings (encoder buffer overflow) when recording PCM at 88.2kHz or 96kHz

12:02:27AlexPWhy are we adding fonts with only numbers?
12:02:55AlexPIf it is wanted for the FM screen I would have thought including it in a theme bundle would make more sense
12:03:31LloreanAlexP: I basically agree.
12:04:16jhMikeSpcmrec would probably be simpler if it had a buffering thread *and* a control thread. right now it weird stuff so it can be responsive to input.
12:04:19LloreanIf a font is to be visible in "browse fonts" it should be able to handle the menus in the default language at a bare minimum.

12:05:06LloreanAlexP: While numerical fonts make sense (for a variety of purposes) there needs to be a situation in place to separate them first (as well as, possibly, a way to load them setting aside much less RAM)
12:06:23LloreanThough there should also probably be a deifnition of what they would include both as a minimum and maximum (digits, colon, comma, period, as a possible example)
12:07:15jhMikeSpcmrec could have much of the core functionality taken from the UI and run by the pcmrec thread instead, making the screen a tack-on piece rather than required.
12:07:23AlexPI agree they make sense, in fact I have done a couple myself for exactly this - I have 40 and 50 point ones for big screen FM

12:18:48kugelwould anyone object to renaming our math.h?
12:18:53funmani don't get what PANIC_SECONDS is
12:19:24funmanwhy is it below FLUSH_SECONDS ?
12:21:59gevaertskugel: why?
12:22:51kugelthe sim uses a little trick to get the system's math.h for code in uisimulator/. that trick doesn't work with the target tree and so it includes our math.h
12:22:52funmanah it just boosts priority when approaching the high watermark
12:23:04 Quit stoffel (Ping timeout: 246 seconds)
12:23:18kugelbut our math.h doesn't declare any functions, but only constants which are not even part of iso c
12:25:02jhMikeSfunman: The panic time is if things are getting too full and it must boost thread priority over other things like UI to get the data out
12:25:42gevaertskugel: traditional unix math.h has the functions, so I think that our math.h really is a stripped down "standard" math.h
12:26:14funmanjhMikeS: it does 'panic' even before the buffer is ready for flushing though
12:26:34kugelgevaerts: ours hasn't got a single function
12:26:53gevaertskugel: isn't the proper solution to move it to libc/include?
12:27:05kugelsome code in uisimulator to be moved into the target tree wants the functions
12:27:14jhMikeSfunman: well, with ATA, if you got under PANIC_SECONDS remaining until full, it panics. if you change buffer sizes, those values have to refect it
12:27:48kugelwell, the sim doesn't use that mechanism yet so it includes libc/include as well
12:28:00funmanhm aren't the watermarks in available recorded chunks, rather than in available free chunks?
12:28:07gevaertsok, then *that*'s the real problem I think
12:29:19funmanhm i must have things backwards
12:29:19kugelactually I asked before committing whether the sim should already use the mechanism to exclude libc/ but you were opposed to that
12:29:19jhMikeSfunman: they're convered to that from remaining time to recorded chunks
12:29:33n1sLlorean: nope, happens on regular transitions too

12:29:40n1samiconn: ah, that sounds plausible

13:50:52funmani give it pointers as argument, the pointers don't change but the content does

13:52:03jhMikeSn1s: well, the DSP needs reconfiguring, there would have to be silence to conceal hardware glitching in the switch
13:52:29funmanhm i guess i could keep track of pcm_rec_dma_get_peak_buffer() calls and modify samples already written
13:52:52n1sah, so it's the switching that's sucky, not the play-at-different-SR?

13:54:00jhMikeSn1s: has to switch at *exactly* the right moment too, so instructions on the buffer itself are needed
13:54:52n1sright, i can imagine it becomming quite complicated...
13:55:04jhMikeSno crossfade either
13:56:02jhMikeSof course the change means voice would have a break in it if it's playing at the time

13:56:47mt:) alright
13:56:53n1sjhMikeS: ah, yes that too
13:57:14jhMikeSe200v1's mic + backlight on is way too noisy for tuner not to get confuser. :\
13:57:25amiconnOn hwcodec it won't be that bad, because there is only one possible source at any time anyway
13:57:26*n1s is getting convinced that switching samplerate brings too much complication compared to the gains
13:57:39amiconnSwitching mp3 -> pcm will take ~1 second though

14:03:46pixelmaUnhelpful: so what I wanted is not possible at the moment? Found that out by trying and wondered if it was by design and if there was a way around that (except preparing album art bmps at different sizes)
14:04:39Unhelpfulright now, no, it doesn't work like that. it should scale to the largest size that fits the viewport while maintaining aspect ratio
14:04:43jhMikeSpersonally, I'd rather an option to run it at say, 48K all the time instead
14:05:39amiconnWell, on hwcodec there is no other choice than switching rate (or even codec) if we want to integrate pcm playback
14:07:31 Quit ucchan (Quit: Leaving...)
14:08:36jhMikeSamiconn: I can imagine. All the concern is in the DSP and PCM output anyway, which isn't HWCODEC at all.
14:09:44amiconnNo, but the pcm packets come from the playback thread afaiu, and integrating pcm for hwcodec means playback engine unification, which in turn means the engine has to learn to tag the packets it outputs
14:10:09amiconnAnd once it's doing that for hwcodec, it could be extended to swcodec
14:12:05jhMikeSit does "tag" on the pcmbuf descriptors to get track transitions right. it calls a callback
14:13:57amiconnIt already does that?
14:17:13jhMikeSyeah, if one is specified for the just-finished buffer in order to let the WPS know when to change over
14:18:05amiconnAh, hmm, so that mechanism just needs to be extended
14:18:28pixelmaUnhelpful: but the principle works in general - in my c200 SBS I load the album art at the same size as in the WPS and then put it in a viewport to crop it to a strip (as a statusbar kind of thing) to not get a "jumpy" look and don't get too small. I just hit the limit of smallest screen dimension which I find a pity
14:19:32amiconnFor hwcodec we'd need a flag to indicate whether it's mpeg audio or pcm, and if it is pcm, whether it's 8 or 16 bit, little endian or big endian (only for 16 bit, obviously), mono or stereo, and which of the 9 possible sample rates
14:19:54 Join Luca_S [0] (
14:21:24amiconnWhenever those flags change compared to the previous buffer, the mas needs to be reconfigured
14:25:08funmanpeakmeter is absolutely identical for both channels on sansa e200v1/c200v1 ?
14:25:19jhMikeSon swcodec it's implement in the pcmbuf. I suppose it would need to be elsewhere for hwcodec.
14:25:44kugelgevaerts: ok, so also exclude the .c files or only the headers for now?
14:26:40gevaertskugel: I'd keep headers and c files together, so everything
14:27:51kugelI'm fine with that, but that means the sim cannot detect anymore when these get broken, but I think that's very unlikely to happen

15:01:05kugelamiconn: that doesn't make sense for code which never changes in reality
15:01:28kugelI understand that principle but it's really not needed for this c library code
15:02:21amiconnWell, the sim started out as a pure ui simulator, but nowadays it's actually more like a testbed for everything that doesn't absolutely need the hardware for testing
15:02:48amiconnHence it should use as much of our code as possible, so that we can debug/ optimize/ whatever that code
15:02:55kugelthis code doesn't need testing anymore
15:03:37amiconnOther code might also behave differently depending on the c lib stuff in use
15:05:41kugelthen the code is wrong
15:07:13pamauryamiconn: I don't see your point, the c lib is the c lib, it has a well define semantics that doesn't depend on the implementation
15:07:21 Part tscherny
15:07:30pamauryFurthermore, the host libc is better optimized for the platform
15:13:36funmanwhy do we stop max volume at 6dB on sansas? we could make it even higher
15:16:01funmanthe volume steps and limits seem to be the same on as3543 but some people complain it isn't as high as the OF

15:19:19amiconnpamaury: Our c lib isn't a full one, it is cut down (on purpose)
15:19:26pixelmaI only know that the c200 is noticably quieter than my other targets. It's hard to compare with the OF as that one has only 15 volume steps or so and I remember finding the smallest too loud already
15:19:55mtaaand .. sound !
15:20:04amiconnAnd the sim doesn't need to be optimized, it should rather be as close to the target it simulates as possible. Raaa is of course different and should use the host libs

19:22:06funmansaratoga: we don't really need to run the as3525v2 at 240MHz, what worst case codec/profile should I try?
19:22:39funmanis there anything but APE that the PP can't decode @80MHz ?
19:23:38funmanSoundCodecs is all green
19:23:52shodan45my sansa v1 w/ rockbox 3.5 seems to run out of battery when RB says it's around 45% - anyone else see this?
19:24:03saratoganeeds 145MHz on e200v1
19:24:13saratoga(but could be easily improved)
19:24:25*pamaury grumbles about a flash command that is not in the onfi spec :(
19:24:42saratogathough AAC-He is probably a lot faster on ARM9E
19:25:00funman64kaache.m4a ?
19:25:29saratogawow only 99.27MHz
19:25:36saratogaarm9e rocks
19:26:40saratogaheh verses 150.92MHz on the fuzev1

19:29:31kugeldon't we want max. performance for some demanding plugins?
19:29:46amiconnUhm, no variable clock on as3525v2?
19:29:50funmani think we don't care about plugins, more about battery
19:29:57kugeli do care
19:30:13saratogathe fuze (and more so clip) have amazing CPU to screen size ratios
19:30:24funmanamiconn: buggy -> disabled
19:30:31funmankugel: the same plugins run on e200v1
19:30:44kugelyes, but worse
19:30:48*amiconn thinks this needs fixing, then
19:31:03kugele.g. since I play bubbles on the fuze I find it unplayable on the e200v1

19:33:03saratogarockboy is probably the only one that actually needs higher clocks on the fuzev2
19:33:16funmansaratoga: needs 160MHz on clip+
19:33:24kugelI'm not a fan of trying to hide the freq switching problem by clocking down the max. clock
19:33:53saratogawe should just add a max clock speed option to the plugin lib
19:33:58pamauryTorne: the flash seems to have quite a few commands that are not in onfi, do you know a good reference for that where I can find the model or the datasheet for example ?
19:34:06saratogaand let plugins request higher boost if they want it
19:34:13kugeland I think that once that works the advantage from going from 240MHz to 120MHz is entirely vanished
19:34:16funmanit's not hiding i think, this doesn't work at all and we want correct battery life

19:35:57 Join huelk [0] (
19:36:09funmansaratoga: pclk is 24MHz, and 40MHz on the fuze because of bigger color display
19:36:24saratogahmm that sucks
19:36:32funmanit's ok when boosting though
19:36:57funmanso yeah just let things that way
19:37:40*amiconn remembers hunting the PP5002 crashes related to cpu sleep
19:38:04tmztanybody still working on zune seen this:
19:38:12amiconnOh, and also unlocking higher clocks than 66MHz
19:38:22funmanif i can plug a jtag adaptor on clip+ i can look in OF the conditions where it changes the clock (if it does it only at boot, and if not what are the input & output clocks of the function)
19:38:22amiconn(something ipl still doesn't do)
19:38:24saratogathe "work at >66Mhz bit"
19:39:17saratogafunman: seems I was wrong, my clipv2 gets 161.69MHz on aache
19:39:50funmanah i thought you tried on fuze
19:40:08saratogathis reminds me, does anyone know why the D2 doesn't seem to use IRAM?
19:40:08funmananyway the amsv2 work pretty well already
19:40:35funmanwhen FlynDice fixes microSDs, pamaury write the USB driver, and bertrik fixes the charging bug, everything will be perfect O:-)
19:40:46saratogathat result confuses me though, i can't imagine how anything could be slower then on the fuzev1
19:41:40funmansaratoga: try
19:41:58funmandunno if 72MHz would be too much
19:42:39saratogawill try on the clipv2
19:42:56saratogathats just the DRAM and not the IRAM?
19:43:19funmanthat's DRAM, PCLK, and 'NORMAL' cpufreq when boosting is activated

19:44:16shodan45can someone confirm my battery problem? or is my battery dieing?
19:44:32funmanshodan45: what does the OF say about the battery ?
19:46:32saratogafunman: its a lot faster
19:46:51saratoga114.8MHz needed for aache instead of 161 from before
19:47:22shodan45funman, seems about the same right now
19:47:58FlynDicefunman: I thought SD was working fine now, is there something I missed?
19:48:08shodan45guess that means it's the battery huh? ;(
19:48:12funmanFlynDice: i have some problems with µSD
19:48:38FlynDicestill? I wasn't aware. What's happening?

19:49:25funmandidn't look in details, i have plenty of space on the internal storage ;)
19:49:32FlynDiceall targets?
19:49:43funmannot the clipv2 though
19:50:23***Saving seen data "./dancer.seen"
19:51:46saratogafunman: so this patch increases the DRAM/IRAM speed when boosted?
19:52:53funmansaratoga: nope boosting is disabled in SVN and anyway pclk/dram/iram speeds are fixed (we change the divider when changing fclk==CPU speed)
19:53:18saratogaah ok
19:53:34funmanon AMSv1 pclk and fclk are divided from the same clock (PLL) but on AMSv2 only fclk is divided from this clock, and pclk is divided from fclk
19:53:57saratogaso this increases it from 24 to 40MHz?
19:54:30funmanwe can do only integer fractions of 240MHz (cpu speed)
19:54:59funmanthough we could also do 5/8 6/8 or 7/8 of the PLL (240MHz) for the CPU speed
