#rockbox log for 2008-10-23

00:00:15 Quit tvelocity ("Αποχώρησε")
00:00:26ThedjatclubrockCan iTunes export as .m3u?
00:00:58scorcheThedjatclubrock: ask them...
00:01:28 Quit moos ("good night europe")
00:02:34 Quit mirak ("Ex-Chat")
00:04:08 Quit n1s ()
00:04:26fmlXavierGr: pong. I just added a task (FS #9504) that should help in FS #9455
00:04:29*bluebrother points to the IpodFAQ ...
00:05:13XavierGrok let me see
00:05:13 Join neddy [0] (n=john@nat/sun/x-7ce0d697352b667d)
00:06:37XavierGrfml: yes it would eliminate the last length parameter in my patch
00:06:50XavierGrfml: about strncat on lcd-x files
00:07:02fmlXavierGr: if FS #9504 is committed, you can make the definition of the max length of the padding string (in settings) as complicated as you want and will not to have to care about the matching definition in settings_list
00:07:17linuxstbfml: I see you changed a comment to say "filename (or another string)" - maybe the macro should be renamed, if it's not specific to a filename?
00:07:44fmllinuxstb: yes, it can handle any string, not only file names
00:08:03fmllinuxstb: but it would be another patch :-)
00:08:07ThedjatclubrockCan RB DB use iTunes Album Art?
00:08:19krazykitThedjatclubrock, no
00:08:20fmlXavierGr: what about strncat?
00:08:23XavierGrfml: for the last parameter of strncat, to make it safe, I have to subtract the size of the destination array with its current length
00:08:50XavierGrbut is the size of the destination array known?
00:08:54fmlXavierGr: correct. And then set the last char to 0.
00:09:01ThedjatclubrockThere should be a RB program, cross platform, Java or C with Qt
00:09:06ThedjatclubrockOr Swing
00:09:17linuxstbYou mean like Rockbox Utility?
00:09:23fmlXavierGr: yes, it's known. It's the size of the padding_string array in the firmware layer.
00:09:51XavierGrfml: sizeof(s->line) should return the size of the pointer instead right?
00:09:55fmlXavierGr: or just use snprintf. It does add the terminating 0
00:10:22XavierGrfml: I tried using snprintf but it failed for a reason, I didn't search thoroughly though
00:10:42krazykitThedjatclubrock, for converting album art? there probably is some software already written to do it, but feel free to write it yourself too.
00:11:02pixelmalinuxstb: I overlooked the "line" and thought you were talking about an overall size limit for .wps files... but with viewports it's not so clear anymore. Hmmm, I also wonder what lines are counted
00:11:43fmlXavierGr: where is that s-> line defined?
00:11:54fmlXavierGr: lcd.h?
00:12:08Thedjatclubrockkrazykit: No, like, iTunes for RockBox
00:12:21 Quit sarixe ("Ex-Chat")
00:12:31ThedjatclubrockOr a Banshee/RhythmBox plugin
00:12:35XavierGrfml: look at lcd-16bit.c where my patch does the strcat
00:13:28krazykitThedjatclubrock, er, itunes does work for rockbox, and since it's otherwise an MSC device, your media player may support syncing. i know amarok does, and i'd suspect others do too.
00:13:31XavierGrfml: hmmm, never mind scroll_engine.h which has the define for the size of that array is included
00:14:13fmlXavierGr: yes, but how is the "line" member defined? I see it's a part of the lcd_scroll_info.scroll struct. Where is it defined?
00:14:21Thedjatclubrock Amarok has native RB!
00:14:44XavierGrfml: why are we so fixed on making the last char 0? It seems to me that all methods append the null correctly. Or do we want better safe than sorry even if we sacrifice one command
00:14:44linuxstbThedjatclubrock: One of the design goals of Rockbox is that it's not dependant on any specific PC application - you simply need to drag and drop your files, and Rockbox will play them.
00:14:56fmlXavierGr: yes, the sizeof(s->line) should be fine
00:15:25XavierGrfml: I thought that this (sizeof(s->line)) will return the size of the pointer not of the array
00:15:42Thedjatclubrocklinuxstb: Yes, great. I'd also suggest that there be a plugin in iTunes, Banshee and RhtyhmBox to port album art and playlists and a DB.
00:15:47 Quit meven (Remote closed the connection)
00:16:04fmlXavierGr: because it can happen that the size of the dest array is less that the copied string. Then, when you use strnXXX, you won't overrun the array but the string in the dest array will not be zero terminated
00:16:10XavierGrfml: scroll_engine.h struct scrollinfo
00:16:25 Join stripwax [0] (
00:16:27linuxstbThedjatclubrock: Just use any PC application that uses the standard m3u playlists, and there is no need to port them. As for the DB, Rockbox builds it itself.
00:16:47XavierGrfml: I understand the use strncpy and strncat, I don't understand the extra command of zeroing out the last char.
00:17:00fmlXavierGr: yes, found that. The field "line" is a char array ( char line[xxx]) hence sizeof (line) will give the size of that array
00:17:12 Part L29Ah
00:17:18fmlXavierGr: see my explanation above
00:17:24scorcheThedjatclubrock: you are free to make one yourself...
00:17:33stripwaxstrncpy won't guarantee the string is zero terminated
00:17:40fmlXavierGr: this is to make sure that the dest string is always zero terminated
00:17:49ThedjatclubrockI would, but I am not great with my dev skills
00:18:18XavierGrfml: yeah, that's my point, it is always zero terminated by other functions, eg. settings loading and virtual keyboard in our case
00:18:27 Quit culture (Read error: 110 (Connection timed out))
00:18:56fmlThe buffer size in the firmware layer must not necessarily match the setting size in the app layer (since these two pieces of code are not so closely related).
00:18:58XavierGrI mean if the dest string is always null terminated and the appended string is null terminated how the new string can end without null?
00:19:38XavierGrbut okay I guess one more command shouldn't hurt
00:20:11fmlXavierGr: if the appended string is truncated (because the dest buffer is not large enough to hold the whole string), then the dest buffer will not be zero terminated after strncat
00:21:03fmlBut it will always be after snprintf. So either strnxxx + set the last char to 0 or just snprintf
00:21:10XavierGrfml: about the MAX macro. Currently it is not included on the files the padding is defined, I am not so sure it will be good to define them just for the player
00:21:24XavierGrfml: which is the only target with so little screen width
00:21:37XavierGrI think ifdefing for that case alone is enough
00:22:06XavierGrbecause the ifdefs are already there for e.g scroll step
00:22:21fmlXavierGr: I'm actually not sure we have to ensure that the setting is at least 10 chars. Of course we don't have to define a macro for that, this was just a scheme.
00:23:00 Quit mcuelenaere ("Zzzzz")
00:23:03fmlYou can write e.g. LCD_WIDTH/4 < 10 ? 10 : LCD_WIDTH/4
00:23:26XavierGrOndio seems to be next with 112 pixels LCD_WIDTH which is plenty after the division with 4 (to fill a screen)
00:23:43XavierGrfml: yeah that can be done too, but won't some consider it more confusing that the ifdef?
00:23:43fmlThis is a rather complex definition. Hence it's highly desireable that it doesn't have to be repeated anywhere else. Hence FS #9504.
00:24:34fmlXavierGr: we need that only if we want to ensure pad length >= 10. But do we want that? I'd say no for the first try.
00:24:45 Quit colesterol_dog (Read error: 104 (Connection reset by peer))
00:25:02XavierGrfml: LCD_WIDTH / 4 is used currently on 3 files
00:25:16XavierGrthe one you tried to avoid with your patch
00:25:24 Join m0f0x [0] (
00:25:42XavierGrsettings.h and scroll_engine.h will still need it
00:25:50fmlXavierGr: hence leave this part of the code as it is. With FS #9504 you won't have to repeat anything. Later you can make the size definition (in settings.h) more complicated −− and still not have to adjust anything else!
00:26:27XavierGrfml: what do you mean exactly, leave the code with the ifdef?
00:26:35XavierGr(for the player)
00:27:28fmlXavierGr: where? settings.h −−> ok. settings_list.c −−> eliminated with FS #9504; firmware code? With proper usage of strn-funcs, you can set the size of the string in the firmware layer to another value, everything will still work.
00:28:01fmlXavierGr: leave the code = no need to ensure that the length is >= 10
00:28:29 Quit feisar (Remote closed the connection)
00:28:35XavierGrfml: scroll_engine.h also uses LCD_WIDTH /4
00:29:09XavierGralso if I don't ifdef the player the setting is useless for that target 11/4 only 2 chars, lower than the default. (actually one char and the other the null)
00:30:07XavierGrso I will just ifdef player and later we'll see
00:30:15fmlXavierGr: yes, but IMHO it doesn't have to. I mean, the firmware value can be seen as a capability of the hardware. Of course it's good if we defined our settings' (app layer) size to exactly match that value. But we don't have to.
00:31:36fmlXavierGr: no,no I mean the defferentiating between char and dot displays is OK. My proposal was to ensure (only for dot displays!) that the max size is at least 10
00:31:51XavierGramiconn: is the M3s remote screen defined as a main LCD or REMOTE_LCD?
00:31:59fmlBut, as I said, I doubt we need that.
00:32:24XavierGrfml: ah okay then
00:32:43pixelmaXavierGr: main LCD
00:32:46 Join feisar [0] (
00:33:04XavierGrpixelma: phew, thanks, that saves me from something :)
00:33:13pixelmaon the M3 but it's the same remote you can use with an M5 or X5
00:33:13fmlSo leave this as it is. If some users of dot displays with WIDTH<40 will complain, we will add this "10". Nothing else will need to be adjusted.
00:33:53XavierGrfml: agreed. So nice we can finally talk about it in IRC, the tracker was tiresome for little details
00:34:13XavierGrfml: anything else?
00:34:31fml:-) I hope all points are clear now.
00:35:09XavierGrok most changes were done yesterday, I will add some more and upload a new patch.
00:35:12fmlXavierGr: but let me look at the next patch (tomorrow, I'll leave now) :-)

09:36:07linuxstbJdGordon: PCM data is normally sent to the DAC in 32KB chunks - using DMA on Coldfire, and a fast interrupt (FIQ) feeding a FIFO on PP (and I think other ARMs).
09:37:07linuxstbI don't know about the other parts of pcmbuf.[ch], but pcmbuf_callback is the "get_more()" function which is called by either the DMA interrupt handler or the FIQ to get a pointer to next 32KB of data to transfer - that code runs in an ISR.

13:01:42B4gderwell, assuming the sims are popular downloads we should probably make them official

14:58:30linuxstbIs that the function the codecs themselves call via the codec API?
14:59:01linuxstbThen that's the function where you can get PCM in lots of different formats.
14:59:03JdGordonits got a nice dsp_proccess() call in which which i assume makes it usable

15:00:18Nico_Pof course that means we need to look at the data going into the DAC, and not what the codec outputs

15:06:35casainholinuxstb: thanks!! :-) I will rectify then :-)
15:07:40jhMikeSJdGordon: but....what particular bit were you wondering about? perhaps I can help.
15:08:12JdGordonjhMikeS: I'm trying to reimplement the pcmbuf so it doesnt do anything fancy (i.e fading), just to be able to get pcm from the codec and put it on the output... is the current patch
15:08:28JdGordonit works, but the output is really fast, and sounds like shit... and i dont know why :(
15:09:05JdGordonalso, line 106 of that patch, if that +4096 isnt there I get a stack smashing and I dunno why, but thats another issue
15:09:40casainholinuxstb: unfortunately, I am getting the same error :-( −− I did changed it on configure file and did "../tools/configure" again...
15:09:52jhMikeSJdGordon: ok, one moment I'll look
15:09:57linuxstbcasainho: Try a "make clean"
15:09:57JdGordonthanks :)
15:12:09casainholinuxstb: even after make clean, the error stills there :-(
15:12:41JdGordonjhMikeS: the patch is supposed to keep giving the codec a 512-1k buffer (whatever it asks for) and keep builing up groups of 32K which are then passed as is to the DAC
15:13:53jhMikeSwhy so large a chunk?
15:14:15JdGordonapparenrlty thats the size the hardware likes... but that can be shrunk
15:14:28*JdGordon would rather get it working at all before fiddling with sizes
15:14:50jhMikeSThe hardware shouldn't care what size it is other than aligned and a full pair of samples

16:19:38jhMikeSJdGordon: one thing is that the count parameter is the number of samples (mono, or stereo pairs) and not bytes
16:20:11JdGordonoh... OHHH>>....
16:20:25jhMikeSthe buffer data should be in int16_t
16:22:18jhMikeSactually for the pcm buffer it's always 16-16 packed pairs so SIZE/4

16:25:19preglown1s: nothing of the sort, but that does sound very much like the error i'm having

16:26:17preglown1s: can't ever recall having installed anything of the kind, and nothing prefixed "arm" exists here, but yeah, it does seem like the wrong assembler gets used

16:27:36n1spreglow: don't remember exactly but googling for "crtstuff" seems to bring up some hits that could be it

Earlier, when I tried to play files, I got a high pitched beep when the file was supposed to be playing. Do you guys have any idea what my problem could be?

19:53:08kb__Hi. I have a 'semi-bricked' sansa e280. It boots into the original firmware and rockbox without problems, but I think the filesystem became corrupt - if I tried to browse files under rockbox, it would freeze, and under the original firmware, it said "bad track" if I tried to play anything. I was going to format it, but it first started showing up as two 0-byte drives under Windows, and then when I next plugged it in under Linux, it
19:53:08kb__wasn't even getting a device node. Now I have it in recovery mode, and I have /dev/sdc, but fdisk -l thinks it doesn't contain a valid partition table. How can I restore it to functional?

19:56:54kb__linuxstb: ok, so, what should I need to do?
19:57:14linuxstbIf the original firmware is working, I think you can simply use the "reformat" option that's available there. (I know the c2x0 has that option, not 100% sure about the e200 though).
19:57:18kb__domonoky: i've read it - I just want to do the least-drastic thing possible
19:57:21kb__the e280 doesn't have it
19:57:27kb__I spent last night checking
19:57:54kb__the usual way to format the e280, according to the manufactor's videos, is to mount it under windows and right-click, selecting 'format'
19:58:32linuxstbHave you tried running chkdsk on it? (or fsck.vfat in Linux) ?
19:58:47kb__I ran fsck.vfat yesterday
19:59:01kb__it was after that that the volumes started appearing as 0 bytes under windows
19:59:55linuxstbOK, then I would probably try the "sansa.fmt" instructions on the page domonoky linked you to.
20:04:47kb__Hm. 2 things
20:04:56kb__a) None of the mi4 files are for the e280
20:05:37kb__b) I do have a working firmware (2, actually) as I mentioned
20:06:22linuxstbI was referring to these instructions -
20:07:26kb__ok, it's formatting
20:09:01kb__ok, it's stopped saying 'formatting' and seems to have gone off; I'll try booting it now?

21:43:15linuxstbIs anyone familiar with the bug that a playlist full of invalid files (i.e. audio files with valid extensions, but ones which are rejected by the metadata parser) causes Rockbox to freeze?
21:46:11LearNot really... Got a number?
21:47:05linuxstbI think it's the cause for this report -
21:47:09 Join Thundercloud [0] (
21:47:30linuxstbI'm pretty sure I've experienced this bug before, but searching flyspray, I can't find it.
21:48:23LearRepeat must be enabled for this to happen, I guess?
21:49:21linuxstbNo - that was my first thought, but when I disabled repeat, it still happens.
21:49:42linuxstbIt's easy to recreated, just copy two mp3 files into a dir, and rename them to ".ogg" (for example)
21:50:51linuxstbIn fact, if you put two files in a directory, rename the second one to a different audio extension, and play that second one, it freezes.
21:51:03linuxstb(this is with repeat disabled)
21:52:46LearDon't see how that last case could happen... :/
21:55:32linuxstbIn fact, Rockbox doesn't freeze at all - just the WPS is stuck at 0:00
21:57:55LearBut it responds to key presses?
21:57:58 Quit dabujo ("( :: NoNameScript 4.2 :: )")
21:58:19LearMaybe playback.c should check for strange values for last_peek_offset and return an error somewhere...
21:58:28linuxstbAlso, my last example was (I think) a different bug... If you take a .mp3 file with an id3v2 tag, rename it to .ogg, then badness happens.
21:59:09 Quit jhulst (Connection timed out)
21:59:36LearDoesn't medata.c select parser based on extension? If so, loading fails... Not sure if I'd call that a bug, as it is by design.
22:00:48linuxstbI take back what I just said - Rockbox seems to (correctly, as you say), reject that mp3 file renamed to .ogg in the same way as any other invalid file.
22:01:40linuxstbI should probably just stop confusing the issue.
22:02:07 Quit {phoenix} (Remote closed the connection)
22:02:18linuxstbIs a possible solution to remove invalid tracks from the playlist, once they've been detected as invalid?
22:02:23LearHm, no freeze in the sim with a buch of bad files, even with repeat all. Sits in wps at 0:00, which doesn't look very good, but...
22:02:57linuxstbLear: Yes, it isn't a freeze as such - just nothing happening...
22:03:06LearThey're already marked as invalid, because removing playlist entries is bad too (e.g., breaks bookmarking).
22:03:48LearSo it should splash "Empty playlist" or "No playable tracks" or something, and error out...
22:04:22linuxstbWhat about the case of one good and one bad file in the same directory?
22:04:26domonokybertrik: i can confirm that your i2c work for as3525 also works on a m200v2 :-)

22:10:13bertrikmc2739, yes I think, but I haven't tried it myself (I don't have an e200v2)

22:11:39bertrikyou do realise that this is all very early experimental stuff that may require you to open your player up and short some pins if something goes wrong?

22:12:09mc2739I understand that. I have used files from the git for testing, but didn't know if svn was able to do the same yet
22:12:46amiconnlinuxstb: Rockbox marks invalid tracks in the playlist so they aren't tried again (at least it used to do that on hwcodec)
22:13:06LearA little at least. Making a build with playlist logf, but I don't have much time for it today...
22:13:37amiconnThis was indicated in the playlist viewer. Not sure whether it still works - I don't have invalid tracks, and I don't tend to try such things regularly...

22:14:47*linuxstb sees that playback.c doesn't check the return value from get_metadata()...

22:15:35 Quit tessarakt ("Client exiting")
22:16:07LearHm, with repeat on and only bad files, playback.c detects end of playlist properly, but the wps still doesn't exit...
22:16:39linuxstbLear: Yes, I'm just looking at buffering.c now, and it simply memsets the mp3entry struct with zeros if get_metadata fails...
22:19:42bertrikmc2739, the e200v2 is the only player of the sansa v2 series than can be "unbricked", so maybe you should try it out
22:20:12Nico_Plinuxstb: that's checked in audio_finish_load_track
22:20:22Nico_Pif (track_id3->length == 0 && track_id3->filesize == 0)
22:20:32Nico_Pline 1753
22:20:37Learplayback.c only sets filling to indicate end of playlist; if nothing was actually playing, playing isn't set to false. So the wps doesn't exit.
22:20:39bertrikthe biggest problem AFAIK is the lack of display support for the e200v2. On the m200v2 and clip we can do some primitive debugging with printf's to the display
22:20:57linuxstbamiconn: My playlist with one good and one bad file shows (ERR) for the bad track in the playlist viewer - so yes, it seems "id3->skipped" is being set.
22:21:28mc2739bertrik: ok, I'll give it a try
22:21:31amiconnNow the question remains what happens if all tracks are bad and repeat is on...
22:21:47LearMaybe add a check for filling == STATE_END_OF_PLAYLIST and not pcm_is_playing somewhere, and stop playback if so...
22:23:03 Join HellDragon [0] (
22:23:07Learamiconn: playlist_peek doesn't find any track, so audio_load_track aborts. playing is true at this point and doesn't get cleared.
22:23:09bertrikmc2739, basic steps are probably the same as for git: configure for e200v2 bootloader, build it, build mkamsboot, run it on the OF image and the bootloader you built to create a new flash image and put that image on the player
22:23:48amiconnIn mpeg.c?
22:24:22Learplayback.c. I'm only looking at swcodec...
22:25:10mc2739bertrik: thanks, mkamsboot didn't look to be the same as on the git, I didn't know if it worked the same
22:26:14LearHm, works as expected (in the sim, with repeat on) with one good track and a bunch of bad ones.
22:26:47domonokybertrik: your i2c work only uses the internal i2c (i2cAudMas) ? would it be possible to use the same/similar code for the external i2c (i2cmsi) ?
22:27:21bertrikyes, the two i2c buses are very similar
22:27:59bertrikthe internal one is strictly master, the external one can also be slave as far as I understand
22:28:02domonokyi think the TEA5767 (fm radio) in the m200v2 is on this externa i2c (and maybe also on the i2s)
22:29:14bertrikI just read that the FM chip in the clip and the fuze (Si4702) can also be accessed through i2c
22:30:20bluebrotherwhy should the TEA5767 use I2S?
22:30:34domonokybluebrother: to route the oudio output ?
22:30:54linuxstbIsn't the audio output normally analogue?
22:31:08bertriklinuxstb, exactly what I thought
22:31:14linuxstbi.e. wired to the audio codec
22:31:31bluebrotherIIRC that chip outputs analog audio
22:31:37domonokyso i am probably worng.. .:-)
22:31:49bluebrotherat least back the time I looked at that datasheet for the h100 ...
22:32:02amiconnTEA5767 only outputs analog
22:34:07bertrikwell maybe I need to separate the audio/PMU layer from the i2c layer again then
22:34:27amiconnIt's controlled via i2c (or 3-wire bus, but I don't know any target that uses this mode)
22:37:47domonokybertrik: your i2c code looks so small, we can easily make another on for the other i2c bus...
22:39:06bertrikyeah, it's a bit disappointing in the end to see that something so small took so much time ... :P
22:39:16*domonoky notices that Clip and e200v2 have buttons on those pins of the external i2c, so maybe they use other pins and software i2c for their fm chips ?

22:46:02bluebrotherallele: did you also allocate the required space correctly?
22:46:14domonokylooks like these pins for the external i2c are also already used on the m200v (by the lcd).. so the fm is probably not connected to this..
22:46:30Learlinuxstb: I have a fix that seem to work (in the sim at least). Doesn't trigger an end of playlist splash, but ordinary (in-ram playlist) playback doesn't trigger it either, so... Probably best to add it to the patch for some better testing.
22:46:51allelebluebrother: you mean changing the size of the array? if so then yes
22:48:35*shotofadds thinks this m200v2 business is going to get very confusing very quickly. In my hand I have a Telechips-based M200 which has a PCB printed with "revision v2.0". Rockbox's "m200v2" target is *rather* misleading...
22:48:55shotofadds..especially since we will need a v3 target for the HARP-based ones too

22:50:42bluebrotherhaving m200v4 and e200v2 being rather similar sounds kinda confusing too ;-)
22:51:00BagderI think the ams suffix idea sounds fine!
22:51:22alleleI'm wondering if the plugin would be iterating through one of the arrays while the plugin is ended

23:02:24drownerI was under the impression it needed to be hacked manually?
23:03:18bluebrotherah, it's libgpod these days
23:03:44drowneroh well
23:03:57drownerhow is the development for rockbox on classic going ;)
23:04:02***Saving seen data "./dancer.seen"
23:04:13bluebrotherit's going very well, given that there is no development ;-)
23:05:42drownerI just can't believe the nerve of apple
23:05:54drownerat least i got a cheap classic, i suppose
23:06:28drowneranyhow dudes, i'm off to work.
23:06:33drownerI shall catch you all
23:06:39drownerthankyou for your assistance. Bye!
23:06:39ameyerbluebrother: they reverse-engineered it within about a week if I recall correctly
23:06:44bertrikthere seems to be quite a bit of code for the e200v2 display

23:27:12ameyerif anything as a F you to Apple for the encryption

23:27:52ameyerwell, that and the non-trivial encryption
23:28:13BigBambi Yes, we all think that it is mightily unlikely
23:28:54Nico_Pameyer: IMO a F*** you would be to crack it :)
23:29:31Nico_Psomeone on the linux4nano ML mentioned an attempt to brute force it, but hasn't posted any updates since

23:30:07Nico_PI don't think they see it like this
23:30:17linuxstbameyer: But they don't sell them any more (or at least, some of them)...
23:30:47ameyerwouldn't surprise me to see an iTouch port, though
23:30:48Nico_Pif they saw us as any help selling ipods, they wouldn't have locked them
23:31:11ameyerI'm not a developer, so I don't count.
23:32:08ameyereven if I wanted rockbox on the newer ipods, it's not like I could do anything, so my opinion on the matter doesn't count
