03:46:53Tornei don't really know why rolo doesn't work to load the of on pp ipods
03:47:08[Saint]Torne: I found a couple of posts from you indicating that RoLo is *not* expected to work with the Apple OF. For that reason is this? Can it be overcome?
03:47:21Torneit's not expected to work because it doesnt' work and nobody knows why
03:47:22[Saint]*for what
03:47:31Torneit reliably, consistently doesn't work :)
03:47:37Torneso, yeah. expectations
03:47:53[Saint]I can get diagmode and diskmode working.
03:47:57[Saint]But not the OF.
03:47:59Torneit may be reklated to the longstanding reboot bugs on pp ipods
03:48:10Tornewhere it falsely thinks battery is dead
03:48:20Tornebecause of some state in ram soewhere
03:48:40[Saint]Trying to RoLo the OF stals at "RoLo Executing..."
03:49:04Tornewell not really :)
03:49:10Tornei imagine it just crashed
03:49:21Tornebut after having overwritten our vectors
03:49:33Tornethe apple vecotrs aren't much good for debug :)
03:50:02Tornereverse the flash bootloader fully sometime to deduce wghat state the hw shiould be in\
03:50:14Tornei truied but that cofde sucks hard
03:50:30Tornelots of fun refs to pp chips we dont know exist etc
03:50:37[Saint]I can get the iPod to Rolo into diskmode, but I rather suspect it isn't "set up right"...the backlight stays on and it only connects as a high-speed device.
03:51:13Torneyou mean full speed
03:51:28Tornehigh spreed is what you want :)
03:51:48 Quit rdn (Remote host closed the connection)
03:51:57[Saint]Gah. I do, yes. Sorry, I confuse the two.
03:52:04Torneit alkl expects the hw to be in known state from flash bootloadr
03:52:17Tornesorry for terrible typing, rsi issues
03:52:42[Saint]Not a problem.
03:53:36Tornewe just dont really know the full details of the of'
03:53:44Torneof's enmvironment
03:53:52***Saving seen data "./dancer.seen"
03:54:01Torneit has a ram block it uses to pass info between binaries
03:54:03[Saint]So there's no technical limitation as to why RoLoing the OF couldn't just...doesn't.
03:54:12Torneand to handle suspend
03:54:19Torneno, of course not
03:54:43Tornetheres never anything stoppibng us purtting the hw back how it was
03:54:56Tornewe just dint know whiuch part of how it was ids important
03:55:09*[Saint] nods
03:55:36[Saint]Thank you for your input. It is valued.
03:55:47Tornei guessed issues were caused by the ram block for state
03:56:06Tornebut i cleared it explicitlky in a bubnch of ways and it didnt seem to help
03:56:23Tornetyrying to fix the poweron false low bat bug
03:56:31[Saint]I guess I'll poke RoLo so that it rejects apple_os.ipod
03:56:42Tornecould do.\
03:56:48[Saint]or, anything that isn't rockbox.ipod or diskmode or diagmode, I guess.
03:57:43 Part Torne
03:58:13[Saint]diagmode is quite useful, I might even look at the possibility of splitting the image out from ROM on-device.

04:32:16[Saint]Why doesn't bufflib reclaim available buffer when the buffer is replenished?

11:07:56copperwhat stands out from Googley is the number of conditionals and unused viewports
11:08:42copperI wonder if any of those facts are relevant in this matter
11:10:33lebelliumI don't know, but it looks like that the issue with my themes are due to some memory corruption. It's a Rockbox problem, I won't simplify my themes because of that :)
11:17:54copperif the theme upload system allowed multiple .cfg file in the archive, I could simplify my themes a lot and just offer alternative .cfg files
11:18:13copperwith much fewer conditionals and no unused viewports
11:18:50copperright now I could rename .cfg files into .txt files and ask users to rename them themselves, but meh

14:25:58copper[Saint]: replaygain scanning on Linux: caudec -g *.flac
14:26:25[Saint]I need it for mp3.
14:26:47copper-g for replaygain tags, -G album for mp3gain type gain
14:27:21[Saint]Aha. Does it add actual replaygain tags, or alter the audio itself ala mp3gain?
14:27:37copper"-g" only adds replaygain tags in TXXX frames
14:28:00copper"-G album" runs mp3gain, except it does it on several tracks at once (so it's a lot faster)
14:28:01[Saint]I'll have a look, thanks.
14:28:29copperer, "faster" than just running mp3gain manually
14:28:39copper-g and -G are equally fast
14:28:58[Saint]Is there a flag to set the reference level?
14:29:04[Saint]If not, what is the value?
14:29:17copperreplaygain's default, 89dB
14:29:33[Saint]Excellent. Thank you.
14:29:53copperor, you can use foobar2000 with wine
14:29:58[Saint]To make this conversation on-topic, have you considered adding this to the "Useful Tools" page on our wiki?
14:30:12copperhmmm, no I haven't
14:30:15[Saint]I think you should.
14:30:34[Saint]I you ditched your account, or don't have/want one, I could add it.
14:30:38[Saint]*if you
14:31:01coppernah I still have it
14:31:28[Saint]It would be nice if you added it here:
14:31:45[Saint]It seems to be a fairly simple, yet diverse, tool.
14:32:09copperit got feature creep though
14:32:18copperI need to rewrite the whole thing, sometime
14:38:31copper[Saint]: er, where should I put caudec? "CD Ripping" or "Other Tools"? LAME is in the former even though it's not a ripping tool per se, and neither is caudec
14:38:52[Saint]"Other Tools", I would say.
14:39:02coppermaybe I can rename "CD Ripping" to "CD Ripping / Encoding"
14:39:35copperor create an "Encoding" category of its own, with LAME and caudec in it?
14:40:03coppercaudec does more than encoding, so I guess "other tools" it is then
14:40:06[Saint]Ah, yes, that sounds like the plan.
14:41:11copperor, "Audio Tools", right before "Video Tools"
14:41:51copperwhat qualifies as "freeware"?
14:42:07copperanything that's free as in beer?
14:49:46[Saint]free as in beer, not necessarily as in freedom.
14:51:09copperhmm, I'll add foobar2000 to the list

15:54:07[Saint]My collection is approximately 50% 48000Hz and 50% 44100Hz (foobar2000 tells me {rather helpfully} that its a 48.2/51.8% split)

15:57:23[Saint]AFAIUI, there is no additional cost to playing 44100Hz audio with the samplerate at 48000Hz.
15:59:24[Saint]The first time I tested 48000Hz playback in Rockbox on my iPod Classic there was a rather noticeable audio glitch, ...but that doesn't appear to happen anymore. So, yay.
16:02:54lebelliumI thought this setting was for recording only?
16:04:12copperno, I believe it was designed initially to accomodate Opus collections
16:04:19gevaertsIt's fairly new
16:04:29[Saint]lebellium: Nope.
16:04:48[Saint]The recording and playback frequency selection are independant of each other.
16:05:13copper[Saint]: where do you get your 48kHz material from, in such large numbers?
16:05:31[Saint]I lot of it is from
16:05:37[Saint]*A lot
16:05:51copperwhy would they resample CD audio to 48kHz? o_O
16:06:21copperer, I seem to remember that some stupid ass "scene" groups used to do that
16:07:17lebelliumI don't understand why they would extract their CD in 48kHz on
16:07:40[Saint]I just said in *-community to evilnick that I didn't set out to grap 48000Hz stuff specifically, it just kinda happened...I have no idea of the source.
16:08:14[Saint]The stuff I've transcoded is all 44100Hz
16:09:13copperanyway, maybe ask saratoga if 44.1->48 is better than 48->44.1 or vice-versa
16:09:18[Saint]I guess there's some audio that is legitimately 48000Hz, and rather a lot that was upsampled for no reason other than higher numbers are better.
16:09:27copperI think he's the one who ported the new resampler
16:09:45[Saint]I think it was JhMikes
16:10:21copperthough I guess setting playback to 48kHz makes more sense if a lot of your content was already resampled from 44.1 to 48
16:11:06copperso that 100% of your content only ever gets resampled once
16:13:10n1s[Saint]: there's an additional cost to play back 44.1kHz at 48kHz, upsampling and more data for dsp to process means more cpu utilization

17:12:06KotHfunman: fun stuff: cowon uses quicktime, probably for video coding
17:12:54funmanKotH: inside the player, or in a PC suite?
17:13:11KotHinside the player
17:13:40KotHa cursory look at the binary revealed something that looks like a library structure and one of those seems to be quicktime

17:55:09saratogai don't think 44.1k -> 48k -> 44.1k is much different, should each be roughly as efficient and introduce about the same distortion

20:13:52gevaertsIf you have a question, just ask, and if someone knows the answer they'll reply
20:14:24zipaaaI wanted to ask if there is information on samsung yp-q3
20:14:36zipaaai'v goolged time and time
20:15:47gevaerts mentions it, but in a rather vague and indefinite way...
20:16:04gevaertsI don't think I've seen much discussion about it here, if at all
20:17:02gevaertsYou might want to talk to pamaury though when he's online, he's the one who knows most about those STMP3xxx chips
20:19:10zipaaaim intrested to modify/hack my player, i'v just discover that samsung release their firmware source, but that one of Q3 not released yet
20:22:59zipaaaim tryng to reverse original firmware, but i cant do much :/
20:23:34*gevaerts can't help with that
20:23:38gevaertsNot my area...

20:27:38[Saint]I guess it depends how different it is to the YP-R* players.
20:29:25zipaaano info anywhere
20:30:47[Saint]Hardware information for new ports is usually obtained the good old fashioned way. Dissassembly.
20:32:09[Saint]The above link describes the processes involved in getting a new port off the ground, somewhat.
20:32:43zipaaaim reading..
20:33:22[Saint]Bits of it do seem overly harsh, but that is primarily due to the level of work involved ranging from "really hard" to "exceptionally f***ing hard". :)
20:34:33[Saint]Whereas some ports can have very similar hardware and composition to an existing port, and only relatively minor changes are needed.
20:35:51[Saint]In some instances you might find that someone has already done a lot of the major legwork for you. In others you might find you need to start completely from scratch in many areas.
20:36:09zipaaai think if samsung will release the source (like R0) it will be easy
20:39:00zipaaa"BTW, the Q3 uses the same chip than the YP-P3 (Telechips TCC7901)"
20:39:07zipaaaand found photo!!
20:41:56[Saint]so you're likely safe from bricking with tcctool, which is nice.
20:42:39zipaaai can start a new page on rockbox add that info?

20:57:28[Saint]Ooooh, I remember now! That's right. I was going to ask:
20:58:07[Saint]What is the 34 byte 'test' allocation in bufflib?
20:58:48[Saint]Every other allocation is easy enough to work out, but this one confuses me. I have no idea what it is.
20:59:07gevaertsIt's mainly there to confuse curious people :)
20:59:39gevaertsYou can only see it if you deliberately ignore the "Keep out!" instructions!
21:01:04[Saint]...whatever it is, it seems to be irrelevant to functionality.
21:01:21[Saint]It can be deallocated with no ill effect.
21:01:31gevaertsIt improves stability
21:01:49[Saint]And then if I force a rebuffer, I get a whole extra 34 bytes of audio buffer!
21:01:54gevaertsYou're now so busy trying to figure out why it's there you're not looking at areas where you can do *real* damage

22:38:21FevethLooking for help with a screenless MP3 player I am planning on porting Rockbox to.
22:39:10wodz[Saint]: This alloc is as the name implies is for testing. You can force deallocation which triggers whole chain of action with move callbacks.
22:39:28wodzFeveth: What hardware it is?
22:39:32Feveth Namely, I need to find some more info if anyone has some.
22:40:56FevethIt's a player which has a ROM partition that labels itself as a CDROM and a main storage partition.
22:41:11FevethI've no idea what this is, besides a fake iPod Shuffle 2G.
22:42:22FevethIt has a 3.5mm headset jack, and a miniUSB port.
22:42:27FevethNot micro, mini.
22:42:35FevethI've taken pictures.
22:42:53FevethJust a moment, I'm tossing them on the net and redoing the paste.
22:43:01wodzfirst you need to figure out what this SoC actually is
22:43:10 Join Zarggg [0] (
22:44:27[Saint]Indeed. Ascertain if it is even worth continuing.
22:45:44FevethIt has no screen. I want to continue and port Rockbox to this thing as a proof-of-concept that it can indeed support screenless players.
22:45:55gevaertsToo late!
22:45:57FevethThis will require voicefiles for everything.
22:46:02gevaertsThere's the iaudio m3 :)
22:46:04wodzFeveth: From the quick google query this is 8bit mcu + DSP most probably. No go for rb in this case.
22:46:33wodzrb assumes 32bit almost everywhere
22:46:48FevethWell. I would rewrite the code either way.
22:46:51FevethMore info is needed.
22:46:55FevethMeanwhile, I'm AFK.

22:49:59[Saint]That's a *massive* re-write.
22:50:02wodzFeveth: You may try to ask the manufacturer of the SoC for datasheet. They seems to disclose datasheets for some of their chips
22:51:05[Saint]I can't actually find this series SoC on their site.
22:51:20[Saint]Only SH88*

23:58:20gevaerts mentions it, and that's from 2009, which does reinforce that feeling
