#rockbox log for 2007-10-21

00:00:15kugeli wonder why. does the flash memory die earlier with dircache?
00:00:22mrkikoIf someone can help me, I'm available - I will not repeat this message so no one will annoy. Thank forreplies.
00:00:34Slasherirasher: how about displaying a message that reverse scan was not performed when entering into tagcache screen?
00:00:43ddaltonmrkiko: I sometimes find the same problem.
00:00:57ddaltonactually 5 chrashes last night in half an hour...
00:01:12mrkikoddalton: oh... what player do you use?
00:01:25Slasherikugel: nope, it's just so fast that there isn't much benefit from dircache
00:01:27mrkikoddalton: wowowowo
00:01:45Slasherino spin-up times, fast seek etc.
00:01:47mrkikothis is my happy night! :)
00:01:47rasherSlasheri: I agree with dircache not being terribly useful on non-flash, but.. a) It's slightly faster than reading the FAT b) some people are using multivolume with hdd.
00:01:48 Quit Mouser_X (Nick collision from services.)
00:02:03ddaltonrasher: How do I make the .talk clips for the db using your perl script?
00:02:06mrkikoddalton: how did you reset it? I need help from someone.
00:02:28ddaltonmrkiko: by pressing the button on the side of the unit...
00:02:38 Join Mouser_X [0] (n=someone@
00:02:40rasherddalton: well you run the script and pass it thw options it needs, basically. What's not working?
00:02:45mrkikowith something like a pencil?
00:03:00kugelbut there isn't a real drawback of dircache on flash, or?
00:03:00rasherddalton: also note that Database doesn't support it yet, so the clips are rather useless on their own
00:03:10Slasherikugel: shouldn't be
00:03:17ddaltonrasher: I can't work out what options I give it. Can you give me an example
00:03:21Slasherikugel: so far that patch looks ok
00:03:24rasherkugel: it uses up RAM, but other than that no, just not very many advantages
00:03:33ddaltonI want to see how the .talk clips are named so I can try and make them work in the db...
00:04:03ddaltonmrkiko: I used a pin because it has to be very small
00:04:06rasherddalton: ./ -D -t="flite" -T="" -e="lame" -E="" -l="english" /path/to/player/root
00:04:10kugelrasher talked about a hot swap issue with dircache, how about that?
00:04:29rasherkugel: that's what this patch addresses...
00:04:30ddaltonthanks I will try it
00:04:38Slasherikugel: that patch seems to rescan disk when hotswap event is issued
00:04:56Slasheriso it should work too
00:05:15kugeli see
00:05:33mrkikoddalton: have you submitted a bug report? I looked but I can't find one.
00:06:02ddaltonno im not sure how to fix it.
00:06:20pixelmaI thought the real issue wasn't dircache on flash targets bur with the multivolume - and different amount of the ram it needs
00:06:48ddaltonis there a sighted user here than can try something for me?
00:07:09ddaltonmrkiko: Let me see if I can reproduce it.
00:07:39mrkikoddalton: if you want you can reproduce it simly interrupting the voice ...
00:08:39Slasherii think it's ok to commit that dircache patch unless there is anything against it
00:09:17rasherSlasheri: I think you're pretty much the only one who could object against it. Which is a bit of a shame
00:09:40kugelSlasheri: you might contact the patch maker
00:09:45Slasheriwell, i will do something for that tomorrow then
00:10:05kugelhe could be a help
00:10:48ddaltonmrkiko: oh ok just a press of up will do?
00:11:45mrkikoddalton. and... how do you tell when the battery is discharged at all? My reader turned off
00:11:57mrkikobut I would be noticed first (how it happens in the original firmware)
00:12:08mrkikowithout checking the place in themenu
00:12:29kugelSlasheri: the patch is out of sync atm (but only 1 hunk fails), i could upload a sync'd version if you want
00:12:52ddaltonmrkiko: what about the battery? I use a patch that warns me.
00:13:15Slasherikugel: it applied fine without errors for me
00:13:24mrkikoddalton: are you the patch author?
00:13:24ddaltonmrkiko: where do you see this problem? What menu. What key press? A short or long press?
00:13:32Slasherito the latest svn
00:13:36kugelon my sansa there was a hunk failed
00:13:46mrkikoddalton. ...
00:13:55ddaltonmrkiko: which patch? FS #7910?
00:14:07mrkikoddalton: a sequence of ten short pressed in a spoken menus does for me...
00:14:23ddaltononce second...
00:14:29*ddalton Goes and tests
00:14:30kugeli meant, i am building for sansa, which isnt necessary
00:15:16kugelbut nevertheless i had a hunk failed (with the last posted version though)
00:15:37mrkikoddalton. I meant the patch that warns you about the battery being exhausted. I asked you who was the author. And why not just commit it upstream? I'm not a rockbox expert so this is just a question...
00:15:59 Quit w1ll14m ("CGI:IRC (Ping timeout)")
00:16:22ddaltonmrkiko: the one that says the battery level at 50, 30 and 15% is by me yes.
00:16:30ddaltonI am hoping it will be committed.
00:16:40Slasherirasher: i will fix the tc debug screen so that it always shows the current file in realtime
00:16:44ddaltonbut should probably remove the charging stuff.
00:17:19ddaltonmrkiko: I reproduced. Can you give me some time to work on a fix?
00:17:27ddaltonIf I can...
00:17:33mrkikoddalton: congratulations! May be some day I'll be able to program in projects such as rockbox...
00:17:48ddaltonmrkiko: can you program in c?
00:17:58mrkikoddalton: yesss
00:18:23mrkikoddalton. but, for example, i don't know how to debug this problem, since when my reader is crashed I can only notice that it's crashed...
00:18:51mrkikoddalton: d you understand what I mean? I would be very happy if an ncurses-based emulator exist, but for now the SDL one is the only one I see
00:19:19*mrkiko avoided by miracle to use capital letters, avoiding to be kicked :)
00:19:37 Quit ompaul (Client Quit)
00:21:28rasherSlasheri: I don't know if that's strictly necessary - just staticly showing the last one at the time the screen is entered would probably work as well, but it's of course slightly nicer
00:21:38ddaltonmrkiko: I am blind and I am just learning c. so you could probably code on rb. Just got learn where everything is and
00:21:42ddaltonwhat functions to use.
00:21:55ddaltonThe hard thing is testing but with vice that's ok.
00:21:57rasherSlasheri: It'll also help expose problems in tagcache and/or the metadata readers
00:22:07ddaltonThen sighted devs usually tell you if something is wrong.
00:22:17ddaltonBut first write some basic patches
00:22:30ddaltonalso there is a simulator
00:22:33Slasherirasher: indeed, i will just make it synchronous
00:23:24ddaltonmrkiko: Hmmm I can't seem to reproduce it very easily.
00:23:38mrkikoddalton. I developed several programs in C so i may know it (or at least it's basic concepts). My problem has always been to find out what functions of the 'kernel' or the 'core firmware' I should use.
00:23:55ddaltonIf I write a couple of patches for you can you see if the problem still occurs?
00:24:01mrkikoddalton: can you go on the fm recoder -> virtual keyboard?
00:24:27ddaltonmrkiko: where you add a preset and it gives you all the letters?
00:24:29mrkikoddalton. yes! I would be very happy to help you in any manner I can.
00:24:45ddaltonsure hang on one minute
00:25:11mrkikoddalton: is this a question?
00:25:49mrkikoddalton: I'm a little obsessed aniway by crashes: I "love" my iRiver and resetting it make me displease a lot! :)
00:26:25mrkikoddalton. are you the voice-layer writer?
00:26:28ddaltonmrkiko: Ok im there what do you want me to try?
00:26:52ddaltonwhat do you mean by "voice-layer"?
00:26:54mrkikoddalton. then yo may try settings -> record settings
00:27:17mrkikoddalton. voice-layer = the set of instructions regulating voice reproduction
00:27:52mrkikoddalton: The window where you can choose things such as bitrate and so on...
00:28:02mrkikoIf you scroll the menu two or three times it will crash...
00:28:06rasheramiconn: share your displeasure - it helps
00:28:47ddaltonmrkiko: hmmm I can seem to make it re occur. ill will write you up a patch. It will go really really slow but then you can just see if it still occurs.
00:28:50ddaltonAre you blind
00:28:59*ddalton for got the question mark
00:29:30amiconnI need to find the correct init sequence for the small H10's lcd, but the OF puts everything into structures (unlike the apple OF's), hence I can't seem to dig that down :(
00:30:23*ddalton reproduce in the display menu...
00:30:33ddaltonI think it is because of the long lang entry.
00:30:33mrkikoddalton. yes

00:31:05mrkikoddalton. how will you figure out where the problem is?
00:31:07ddaltonmrkiko: re the voice layer question. I didn't write the voice ui but wrote some patches for it.
00:31:15ddaltonsdoyon has done a lot more than me though
00:31:56ddaltonmrkiko: Well I am going to try with action_none. If that works then I need to figure out how to wait on a button release
00:32:07ddaltonactually that doesn't make sense.
00:32:14ddaltonthey are all button releases...
00:32:22ddaltonUnless you hold of course
00:32:33ddaltonmaybe detect how long it was since the last press.
00:32:57ddaltonmrkiko: have you got your dev environment setup?
00:33:12mrkikoddalton. do you use a remote controller for your H320?
00:33:31ddaltonmrkiko: sometimes

00:40:57mrkikoInfact I'm running that script
00:41:20mrkikothe problem is that I'm using UMTS - not so fat
00:41:26ddaltonmrkiko: this isn't the final way but if we find out it works we know we need to not do anything if there is more than one key press in .5 seconds.
00:41:38ddaltonwait I might have a simpler idea
00:42:51mrkikoddalton: ...
00:43:39mrkikoddalton. but... if yopu interrupt the voice and press another key, shouldn't the system just start saying the other thing and have no effect?
00:43:46mrkikoI don't know if I'm explaining myself

00:44:07 Join Gnu47 [0] (
00:45:29ddaltonmrkiko: I better go but I will be back in about an hour. My problem is that I can't reset a bool variable if we have pressed again.
00:46:22ddaltonBut I might just put the code in action_none and see what happens. Still need a counter. And will be a long delay. But if it works then we can probably figure it out.
00:46:35ddaltonnot a counter a bool variable...
00:47:13mrkikoah... I understood
00:47:15ddaltonmrkiko: talk only if there hasn't been a keypress for 0.5 seconds.

01:04:44 Nick idnar_ is now known as idnar (i=mithrand@unaffiliated/idnar)
01:05:20feindbildwhere can I browse the microsd on the sansa e200? (latest rockbox build)
01:05:51n1sfeindbild: it should be visible in the file browser root as <microSD> iirc
01:06:08feindbildn1s: no =(
01:06:44mrkikoapart blind person: how many of you are interested in including real-tiem speech in rockbox? Would be in your opinion too heavy for an embedded CPU?
01:07:58n1smrkiko: I think it would be great, an can probably be made fast enough, there is an espeak plugin in the tracker but there are license problems (gpl v3 vs v2) :-/
01:08:01mrkikoddalton: when you're back (obviously) can you tell me if you found a trick to turn the player off using the remote controller? It would be very handy but I can't find this info on the manual.
01:08:15linuxstbmrkiko: There's lot of interest in it. There was a Google Summer of Code project, but the student didn't do any work... Plus the plugin n1s just mentioned.
01:09:26mrkikoI seen the plugin in the tracker but, noting no-one is working on it- I was thinking the project to be 'died'
01:09:39mrkikorockbox is gplv3?
01:09:43mrkikoand espeak v2?
01:09:51linuxstbNo, Rockbox is gplv2
01:10:43mrkikolinuxstb: if I'm not wrong, GPL allows generally you to pick a version of espeak made under gplV2 and use it under this license...
01:11:31linuxstbespeak is gplv3, so we can't use it - unless we went back to an older version before it changed to v3.
01:11:33rashermrkiko: yeah, the last gplv2 version of espeak can certainly be used

01:13:50***Saving seen data "./dancer.seen"
01:14:07rashermrkiko: I still think flite is a lot slower than espeak (but I'm basing this on nothing, to be honest)
01:14:09n1sfeindbild: I'm not very familiar with the details but yeah I can imagine that being a problem
01:14:39noztrilzis the sansa release atmo, a finished/complete release?
01:14:59feindbildnoztrilz: USB isn't working yet
01:15:19Zagornoztrilz: software is never finished
01:15:23noztrilzis that all?
01:15:38mrkikorasher: ... you're right
01:15:54noztrilzwhat part of the USB isnt working?
01:16:19feindbildnoztrilz: as far as I know: non. neither charging nor file transfer ..
01:16:43rasherCharging is sort of working, but slow
01:16:45noztrilzi just got the latest release and data transfer works fine
01:16:58noztrilzis that because its using old sansa firmware
01:17:12mrkikohow did rockbox interfere with battery charging?
01:17:17n1smrkiko: also espeak seems to still be developed, its 2 years since the last flite release... (not that frequency of releases is any measurement of activity, but it seems quite dead)
01:18:28mrkikon1s: aniway the activity of rockbox impressioned me...

01:24:25ddaltonZagor: how can I tell in menu.c if it has been pressed released then tapped again in about under a second
01:24:29mrkikoddalton. don't worry
01:25:02mrkikoddalton. the important thing is to note what's happening...
01:25:04ddaltonmrkiko: did you get your environment setup?
01:25:26Zagorddalton: why do you want that in menu?
01:25:44mrkikoI built rockbox already once now to try it :)
01:26:27ddaltonZagor: well if you tap it once it can be delayed for 0.3 and if you tap it twice it won't talk until no activity for 0.3 s. I guess 0.5 would be to long.
01:26:35ddaltonand to stop chrashers
01:26:53ddaltonmrkiko: it worked?
01:27:28rasherddalton: The real solution is to find out why it crashes - not to work around it with a nasty hack
01:27:40ddaltonrasher: ok.
01:27:59mrkikoddalton: yes, it worked
01:28:03ddaltonI think it is voice been interupted. So with voice off it shouldn't chrash
01:28:15ddaltonmrkiko: good.
01:28:35rasherDoesn't voice already work fine with being interrupted before it's done talking? I've never had problems with that in my small tests

01:28:45mrkikobut I'm getting a little tired - I'm up since 6 AM ...

01:41:51mrkikorasher: yes...
01:42:03JdGordonok, well if you commit the callback stuff, ill update that new api for it

01:43:57Buschelhmm, did anyone of you ever get "internal compiler error: in emit_move_insn, at expr.c:3092"?
01:44:09rasherJdGordon: the code that displays and navigates the tagnavi-generated menu. I'm looking for someone to implement the rockbox-side of talking Database

01:44:31rasherJdGordon: I've got clip generation done, now I need someone to put code in to play those clips as appropriate
01:44:31JdGordonno, i tinhk i looked at it once
01:44:42JdGordonSlasheri is the man to ask
01:45:25JdGordonwhere are the talk clips? and how are they linked o a string?
01:45:29rasherTried that, sounded like he wasn't sure how it worked either. Maybe he just wasn't terribly motivated
01:45:38sdoyonrasher: I'll be glad to look at it of course.
01:45:39rasherJdGordon: A folder in .rockbox, named after the string
01:46:07rasherJdGordon: sanitized to be legal fat-name and truncated to 150 chars if necessary
01:46:30markunmrkiko: another advantage of espeak over flite is that it has support for many languages
01:46:30rasheror 100, I forget what I set it as
01:46:48markunmrkiko: and it should consume a lot less memory
01:46:55JdGordonsdoyon: is that voice callback patch committable nowish?
01:47:08JdGordonrasher: i dont tihnk what you want is hard to do at all actually..
01:47:14JdGordonjust need to find the right place to put it :)
01:47:16rasherAlternatively, I suppose I could generate a "language clip db", but I think this method works well enough
01:47:25ddaltonrasher: does it create .talk clips for artist, album etc
01:47:29sdoyonIdeally this doesn't need to be too specific to the database stuff. If we can just lookup strings in general. Could be useful for other things, like radio presets perhaps.
01:47:31rasherJdGordon: exactly.. and I've personally got absolutely no idea where to look
01:47:33rasherddalton: yeah
01:47:40mrkikomarkun: right
01:47:50*JdGordon having a look-sie for ya
01:47:52rashersdoyon: sure, and it could replace the current .talk clip method as well
01:47:56ddaltonhmmm that could be useful for sdoyon's id3 patch as well. maybe
01:48:00sdoyonJdGordon: re voice callback, yes, shouldn't take too long.
01:48:02rasherif desired
01:48:10*sdoyon goes to get list voice callback committed.
01:48:28JdGordonthat callback will make things a bit easier actually
01:48:32ddaltonhey sdoyon: did you answer my question? I might of missed your message
01:49:56JdGordonrasher: hows your c?
01:50:22*markun still thinks we don't lose anything by having a LGPL API file to make it possible to have non GPLv2 compatible plugins
01:50:32rasherJdGordon: not so good
01:51:08markunwell, we lose something of course: control over licenses people chose
01:51:10JdGordon:) well the functinos you want to edit are ft_play_dirname and ft_play_filename in tree.c
01:51:33rasherJdGordon: that's helpful.. those are called even in Database mode?
01:51:40JdGordonit appears so
01:51:53rasherThen it should be a walk in the park from there

02:04:10Nico_PI've been looking quickly at oscilloscope.c and it doesn't do any of the peak calculation itself... everything is done in the pcm code
02:04:27amiconn...even though that means I can't port XSkat, even if I would very much like to have a Skat engine in rockbox
02:05:10amiconnNico_P: It just uses the same data source as the peakmeter, and shows it in a different way

02:05:44amiconnFor swcodec it uses the pcm peak calculation, for hwodec it queries the mas' quasi-peak registers
02:05:46Nico_Pamiconn: yes. I'd like to do something a bit fancier

02:07:05Nico_Pie is pcm_play_dma_get_peak_buffer enough ?
02:07:15amiconnSwcodec - the pcm data. Hwcodec - impossible
02:07:31rasherddalton: I don't know what config options the sapi engine expects. You'd have to check the configure script (or a Makefile created with it for generating voicefiles with sapi)
02:07:53Nico_Pamiconn: I'm doubting this kind of feature would e even wanted on hwcodec anyway ;)

02:16:05JdGordoni changed update_rectangle to just call lcd_update()
02:16:18JdGordonthat got the file browser going, but settings still donot show text
02:16:46JdGordonI asked jhMikeS and he though it might be FRAME getting corrupted or something
02:17:34kkurbjunI don't think it's FRAME
02:17:54kkurbjunI would think the screen would completely fail if that was
02:18:33JdGordonthe wierdest one is the running time screen partially shows text
02:18:50JdGordonit shows the 2 headers, but not the 2 dynamic lines
02:19:29JdGordonunless the lines are changing too fast for the lcd?
02:19:53kkurbjunthere is a controller that handles the LCD updates
02:19:53JdGordonthe disk info debug screen works (completly static info), but the stacks screen doesnt (completly dynamic)
02:20:02rasherJdGordon: only 10 more lists to go before your addition cancels out
02:20:22kkurbjunas long as it's written to the right location it would show

02:51:53J3TC-I mean how harder can it be? >_>
02:51:59ddaltonI can't seem to figure it out in the code. But I think I can voice the db stuff.

02:53:51ddaltonoh it starts at 0
02:53:59ddaltonnot 1
02:55:14rasherStill, what's the point in voicing the graphical eq? It works almost exactly the same way as the menu, with only very minor differences in keypresses. The only advantage to sighted users, I think, is that it's all visible on the screen at once.

It seems that currently it looks for directory clips in /menuentry/ I need to modify this a bit so it would look somewhere saner where I could put talk clips generated by a perl script.
02:59:14pixelmaddalton: in the graphical eq screen the maximum I would voice is the current option you are on, not the values because I think you need to hear the changes to the sound (just my thought when I read that, not knowing what you have planned)
03:00:28rashersdoyon: This I can handle, but the problem comes when file or directory names are compounds of different tags. It's hard to generate a clip for that based on the database files.

03:07:01rashersdoyon: I actually don't know much about the tagnavi syntax, but I imagine directory names could also be made up of multiple tags. For example an albumname with the release year added to the end.
03:07:50sdoyonJdGordon: Right, except you need to call gui_synclist_speak_item(), usually in the same place as gui_synclist_draw() gets called, such as on entering the list.
03:08:47sdoyonUhm... I guess I was naive, but what is tagnavi syntax?
03:09:01JdGordonits horrible :D
03:09:05rashersdoyon: it's the config file used for generating the Database menu tree.
03:09:54sdoyonrasher: I haven't mde more than short visits into the database as you can probably tell. Where's that config file?
03:10:06rashersdoyon: I think the tree_voice_cb in the case where it's called from the Database instead of trying to play the talk clip using the same mechanism, should ask the Database somehow which "parts" the currently selected item is made up of, and voice them
03:10:27rashersdoyon: it's in .rockbox/tagnavi.config
03:10:41ddaltonJdGordon: so what do I copy?
03:10:41rasherI don't really know how it works either - I'm simply using the default

03:12:29rashersdoyon: It's either that, or I need to implement the whole thing in the clip generation script, and I really don't think that's the simpler solution, to be honest. Especially since some of the values such as playcount and rating are dynamic (and should be voiced using the function to speak numbers)

03:41:07ddaltonsdoyon: could you just tell me how to play a beep?

03:42:42ddaltonsdoyon: does it take any arguments?
03:43:26sdoyonddalton: Look it up.
03:45:35ddaltonsdoyon: it has void pcmbuf_beep(unsigned int frequency, size_t duration, int amplitude); so will this do? pcmbuf_beep (22, 100, 10);
03:52:12 Quit criznach ("ChatZilla [Firefox]")
03:52:29rasherddalton: check other places that use that function. 22 is not a good frequency
03:52:59rashernor is 10 a good amplitude
03:54:37ddaltoncould i write pcmbuf_beep(5000, 100, 2500*5);
03:54:47ddaltonit is from playback.c and the original function thing is
03:54:48ddalton pcmbuf_beep(5000, 100, 2500*global_settings.beep);
03:55:05rasherWhy don't you use global_settings.beep as well?
03:55:21ddaltonbecause I want it to beep if beep is off as well.
03:56:16sdoyonThe beep setting is currently under playback options...

04:18:56sdoyonDo we need to know which tag is what, or just to have the individual strings delimited?
04:19:28rashersdoyon: you mean to speak "compound" entries? Just having the strings delimited should work
04:19:57rashersdoyon: actually not quite, now that I think of it. We need to know if it's a numeric value, a time value or a string
04:20:28rasherstrings should be checked in the /talkclips/ dir, numbers and time should be voiced using the voicefile
04:20:47rasherAgain, this seems like quite a bit of work
04:20:58sdoyonrasher: Yes I already meant to parse numeric strings. What does a time string look like?
04:21:13sdoyonrasher: probably not all that much actually.
04:21:44rashersdoyon: I'm not sure, but I believe Rockbox has functions for outputting time - that should be used, so it says "4 minutes 2 seconds" rather than "four colon zero two"
04:22:51rasherI presume (and hope) that value is internally kept in seconds (or milliseconds), and only formatted at the very last stage when putting it in the dirbrowser list
04:23:02sdoyonrasher: it does, but they take a parameter in seconds or milliseconds, so we just need to parse that.
04:23:30rashersdoyon: My hope is that we'd be able to get it from the database part as seconds, rather than the formatted string
04:23:40rasherAnd when I say we - I mean you.
04:25:32ddaltonsdoyon: Thanks for your update to p7910
04:25:37sdoyonrasher: you think the db has it parsed? Could be I suppose. Which tags are time?

04:29:29rasherHowever, the formatting strings used in tagnavi are Lm and Ls - time in minutes and time in seconds (the remainder)
04:29:41rasherSo Lm:Ls gives the duration in human readable form
04:29:49 Join miepchen^schlaf [0] (
04:29:59rasherStill, that could just be voiced as Lm "minutes" Ls "seconds"
04:32:25rasherWhich is somewhat nasty, I guess.
04:33:19rasherThere will also almost certainly always be a colon between them that shouldn't be voiced I guess
04:34:34sdoyonAFAICT the format substitution happens in format_str(), called from retrieve_entries(). Looks like that's prepared ahead of time though.
04:35:14sdoyontagtree_get_entry() calls etrieve_entries() if realid >= current_entry_count ... I wonder when that is...?
04:35:34rasherNo clue
04:35:52ddaltonsdoyon: do you think a single beep for plugging the charger and removing it is ok?
04:36:08ddaltonbecause most people know if they are plugging the charger in or removing it :-)
04:36:11rasherddalton: I don't see why it should beep if beeping is disabled?
04:36:29ddaltonrasher: because it has nothing to do with playback
04:36:49sdoyonOTOH it should depend on some other setting, perhaps talking menus for now.
04:36:57rasherThen I think that setting should be moved out of playback
04:37:34rasherI guess a "blind-user friendly beeps" option could be added
04:37:37sdoyonThat might make sense too. But it might end up used in a lot of unrelated places. I have a beep in the keyboard now.
04:38:24*ddalton wow its getting hot here
04:38:34sdoyonI had a patch to play a short sequence of beeps to form a little tune/song. Makes it more informative. Never really used it though.
04:39:02ddaltonhow would you play a double beep? just put the two functions after each other?
04:39:12ddaltonnot that im going to just wondering
04:39:38ddaltonI will make it depend on talking menus
04:39:51ddaltonbut what if I want it to beep for my charger not playback?
04:39:52rasherIt's make sense to use two beeps in increasing frequency when plugging the charger, and decreasing when unplugging
04:39:53sdoyonI'm not sure actually, it's been months since I looked at beep mixing.
04:41:35sdoyonIn general, beep tunes like this are nice because they are shorter to listen to than a voice msg, and you don't need to interpret speech. It's faster, and also less disturbing if the player is playing a book or podcast.
04:42:12sdoyonAn alternative would be brief .talk clips with sound effects in them instead of speech. I used to have one for LANG_WAIT that sounded good.

04:52:42sdoyonrasher: I imagine there must be a good reason to prepare the strings ahead of time. Who did you say knows this tagtree stuff?
04:52:58rashersdoyon: Slasheri and no one else, I think
04:54:00ddaltonsdoyon: what doesn't talk yet in the rb core?
04:54:29scorcherasher: bad bus factor =/
04:55:01sdoyonrasher: Perhaps format_str can be hacked to add delimiters in the output string. Those will probably need to be taken out before trying to display the text. It leaves us with parsing numbers and time. I'll probably have to parse nubmers anyway at some point.
04:55:56 Nick JRoT|koken is now known as JRoT (

06:40:48ddaltonit compiles the source to an executable code that can run
06:41:04ddaltonso from human readable language to machine language...
06:41:10Renook. seriously maybe that is what i dont understand. where do you get this "source Code"?
06:41:27Mouser_XThat page I linked tells you how, and where, to get the source code.
06:41:42Mouser_X(How is the hard part.)
06:42:13psycho_maniacif you can double click on a exe, extract an 7zip file and do "/run command" commands. you can do it
06:42:33kkurbjunJdGordon: I do have a rotated screen option, but it's noticeably slower with data and code cache disabled and I havn't done the partial updates with lcd_update_rect.
06:43:05Mouser_Xpsycho_maniac, Reno: Perhaps, more specifically, setting it up to *do* the "how" is the hard part.
06:43:30Mouser_XThough, with the VMware image, it's much much easier.
06:43:46psycho_maniacyes. thats what i was refering to .
06:43:47Mouser_X(Though, I've never been able to get that to run in a useable way...)
06:44:04scorcheMouser_X: why not?
06:44:15emeralddgentoo it pretty easy to get working as well but there's a entirely different learning curve there
06:44:25Mouser_Xscorche: I don't know. It killed my PC when I tried to run it.
06:44:35scorcheMouser_X: define kill
06:44:39Mouser_XIt made it horribly horribly slow.
06:44:51Mouser_XJust running it, not compiling.
06:44:52scorchewhat are the specs of your computer?
06:44:55Renoi'm actually not on my computer right now do you guys know how i can download that guide website so i can use it on my laptop? it's got no internet.
06:45:29scorcheemeraldd: he is using windows...
06:45:36scorcheReno: just save the page to a file
06:45:37Mouser_Xscorche: My PC (not my laptop) is a 2 ghz AMD 64 bit CPU, with 512 MB of RAM (as I recall. It might be more RAM...)
06:46:05scorcheemeraldd: why go into that when he can just save the page through a submenu though?
06:46:16Galoisthat's not enough ram to usefully run vmware these days
06:46:23scorcheGalois: sure it is
06:47:23 Quit jhulst ("Konversation terminated!")
06:47:25scorcheMouser_X: did you lower the ram line in the vmx file?
06:47:34Galoismaybe if you use outdated host and guest OSes like redhat 9 or windows xp, then it is
06:47:36Galoisotherwise it's not
06:47:41emeralddscorche: I was thinking the page had child pages
06:47:50Mouser_XI'll say no (because I almost certainly didn't) because I don't know what a VMX file is.
06:47:51emeralddwget -np -m usually does the trick for me
06:48:30scorcheMouser_X: it is the vmware configuration file that is used with the image
06:48:55Renohow do i save the page to a file?
06:49:04Renoi'm using fire fox
06:49:08Mouser_XI recall someone saying to lower RAM usage in VMware, but they never said how.

06:50:12Mouser_XWell, when I get my PC running again (I need a new power supply), I'll try that out, and see how it goes.
06:50:55scorcheReno: keep in mind that you will need to save an archive of the souce and cant use svn to get teh source, as your laptop lacks a network connection
06:51:55Renoi use windows vista on my laptop can i compile and stuff there?
06:52:50Mouser_XReno: Yes, I think all the software you need (be it VMware, or cygwin) should run under Vista (though, I'm not certain on that).
06:52:53Renowhen i right click it says save page as...
06:53:18Mouser_XSo use that option.

07:16:05Mouser_Xpsycho_maniac; Reno: Either way (cygwin or VMware) there's a lot of stuff you'll need to download. The source code is roughly 300-400 MB (at least, that's what it seems like on my laptop here).
07:17:02Renook what is the basic stuff i need
07:17:12psycho_maniaclook at the wiki and it will tell you

You'll need to follow the wiki to do this though. I can't tell you here. Again, there's too much. That's what the wiki is for.

08:25:46 Quit Rob2222 (Read error: 110 (Connection timed out))
08:26:36JdGordonamiconn: the best type !
08:27:53amiconnIt should become smaller on SH1 and also probably on arm if you limit the number of parameters to simplelist_info_init() to 4
08:27:57*JdGordon doesnt know why that commit increased bin size though... i would have thought it would shrink it
08:28:02amiconn(right now there are 5)
08:28:11JdGordonok, ill remove one
08:28:33JdGordonany idea why he ondio fm size didnt change though?
08:28:49JdGordonor just becasue the previous build was larger than it should have been?
08:28:58amiconnBecause it is biased by the build server hopping
08:30:13amiconnThe callback data pointer is often NULL, and it would make sense to drop that and just init it to NULL afaics, since the callback function itself is also just inited to NULL by default
08:30:57JdGordoni was going to drop the selection size one which is used even less often than the callback data
08:31:18amiconnI wonder whether reverting that commit and using designated initializers in the calling functions would be even better...
08:32:02amiconnI mean, remove the init function, and use:
08:34:05amiconnstruct simplelist_info { [title] = "Database Info", [count] = 7, [selection_size] = 1, [database_callback] = database_callback, [hide_selection] = true } info;
08:34:21amiconnOf course brokenn into one line per value
08:34:36JdGordonwell.. that commit was really to simplify it more than to shrink bin size
08:35:00JdGordonback in 10min
08:36:13amiconnThe advantage of that form of initializer is that members without explicit assignment are automatically initialized to zero
08:37:09amiconnEh, sorry, the example wasn't correct for a struct. Should of course be:
08:37:55amiconnstruct simplelist_info { .title = "Database Info", .count = 7, .selection_size = 1, .database_callback = database_callback, .hide_selection = true } info
08:38:07*amiconn confused it with the array form
08:38:21JdGordonyeah, i thought the [] form looked wrong...
08:38:31JdGordonbut that way is still more work for the coder
08:38:52amiconnYOu don't need to list all the elements that should be NULL or 0
08:39:55JdGordonalso, 1) imho that looks more messy than explicilty initing every member, and 2) 0/NULL isnt a same default for all the members
08:43:04amiconnI didn't say it'd be a sane default. But several members are NULL / 0 in the places you converted.
08:43:50amiconnIt was just a thought to reduce the writing in the caller without having an init function
08:43:58JdGordonamiconn: changing topics... on the mrobe some lists work fine, but some everything is displayed except the item texts (tilte, statusbar, icons and scroll bar all show). any idea what function could be broken to cause that?
08:44:12JdGordonive rmeoved one param, we'll see what the delat is
08:46:52amiconnThe m:robe uises standard lcd-16bit.c?
08:47:17JdGordonand there doesnt appear to be anything wrong with lcd_update() and lcd_update_rect()

08:51:24amiconnThese are the very same browsers...

08:51:56JdGordonit doesnt make sense to me
08:51:58amiconnWhat kind of lcd hookup does the m:robe have?
08:52:22JdGordonumm... i dont know
08:53:18amiconnWell, you said that lcd_update[_rect]() is ok, so how would you know that?
08:53:32JdGordonbecause calling it displays the change fine
08:54:53amiconnLCD is memory mapped like gigabeat and e200 afaics
08:55:18amiconnSo I'm almost sure it's a caching issue in lcd_update[_rect]()
08:56:01JdGordonok, so any suggestions on how to try and fix it?

09:23:30JdGordonkkurbjun: all those lists and browsers are drawn by the list which eventaully calls gui_textarea_update() which calls display->update_rect(0, y_start, display->width, y_end - y_start);

10:26:56stevenmamiconn, I hear you know how to use GDB and am in need of help.
10:27:13stevenmamiconn, is there any special procedure to using 'watch' on the Simulator?
10:28:00stevenmamiconn, I gdb rockboxui, set a break within my plugin, then watch my variable. But the watchpoint is never tripped
10:29:26stevenmamiconn, do you have any idea why this could be?
10:30:02amiconnI have no idea. I sometimes use gdb, but when I do, it feels cumbersome
10:30:19amiconnI never used watchpoints in gdb yet
10:30:40stevenmamiconn, well, I have something overwriting a variable that shouldn't be overwritten. How would you go about debugging this?
10:30:43amiconnBreakpoints do work, also in plugins, if you let it load the symbols
10:31:22stevenmamiconn, at one point the pointer points to legitimate memory, then it points somewhere way out to space. Nothing every writes it besides the initial allocation.
10:31:48amiconnIf all else fails, I would do this on a coldfire target, with the 'catch mem accesses' feature hand-tweaked to trigger on the access
10:32:20stevenmamiconn, what do you mean? how can I do that?
10:33:25stevenmamiconn, does it take in a pointer? I don't even know if the variable being overwritten on the sim is the same one as on the target
10:34:04 Part pixelma
10:34:13stevenmHAHAHAHA. This is new. When I try to select 'Catch Mem Accesses' on H300, it locks up when I hilight View IO Ports
10:35:12amiconnThe coldfire has some realtime debug support. It can trigger a special interrupt based on access masks (address, address mask bits and access mask bits)
10:35:27stevenmamiconn, yeah........ once in the Debug menu, pressing Up or Down scrolls the cursor once and then locks up the device. Tried resetting it. This is the fifth time
10:36:25amiconnThe 'Catch mem accesses' feature uses this to trigger on accesses to 0x00........ on coldfire, which e.g. triggers on NULL pointer accesses (also with an offset, e.g. accessing struct members)
10:37:35stevenmHmm. I suppose it would work. GDB seems like it should be working, but isn't.

10:38:20Slasherion H100, it immediately panics when i try to scroll the debug menu
10:38:26amiconnThen I changed the programming of that feature to trigger on the overwritten variable instead of the zero area
10:38:41Slasherimaybe it has something to do with logf, already fixed a few bugs with that
10:38:47Slasheritrying on simulator now
10:38:54amiconnSlasheri: Then the debug menu does something nasty
10:39:28amiconnBasically, if no uninitialized pointer accesses or similar nasty stuff happens, enabling this feature shouldn't be noticeable
10:39:48amiconnstevenm: ...and I found it. An array access was ot of bounds....
10:40:35amiconnHaving e.g. int a[4]; .... a[4] = lol; is a bad idea, isn't it?
10:40:53Slasheriwhere did you find that?
10:41:07amiconnIn some plugin, months ago
10:41:25amiconnAlso, this problem only manifested on archos, although it was wrong for all targets
10:41:40amiconnArchos crashed, probably because of the order of variables in memory
10:42:01amiconnOn SH1 we also have that 'Catch mem accesses' feature, but not on arm
10:42:25Slasherithere was also some wierd stuff with cpu boost logging, two methods are called that should return a pointer to a str but actually doesn't have any return in them
10:42:56amiconnSTrange... no problems with 'Catch mem accesses' enabled on my X5 the debug menu

10:55:54jhMikeSthread.c line 2390 - add set_irq_level(oldlevel) just before the return
10:56:12jhMikeS#if NUM_CORES > 1
10:56:41jhMikeSin any case it should be there :)
11:01:20amiconn(will take a while)
11:01:32jhMikeStakes that long just to make bin?
11:02:00amiconnI am doing a full rebuild to make sure.
11:02:32amiconnA different question: How would you proceed if you need to find the lcd init sequence for the H10 in rom or OF.bin?
11:03:04jhMikeSI think I did already...would need to find it again
11:03:21amiconnIt looks like the lcd driver uses structs all over; I was able to find some places where this struct is initialized, but not where the functions are which actually use it
11:03:33jhMikeSsomewhere searching for lcd-related regs got me there (or parts of addresses)
11:03:57 Quit bertrik ("booting to linux")
11:03:58amiconnI need the lcd register parameters for the small h10 so I can implement lcd on/off etc
11:04:32amiconnI already have a datasheet for that at lists the registers for TL1771 and their relevant bits
11:04:41amiconns/at/at least/
11:05:32amiconn..and I also know the correct R_ENTRY_MODE bits so I could implement asm'ized lcd_yuv_blit() right away
11:06:09amiconnIdeally we can also find where 0x70008a00 and 0x70008a04 are written, in order to find out what the bits mean
11:06:19jhMikeSASM optimizing week? there's been a flurry of codec/lcd optimizing recently.
11:06:43amiconnSetup for small H10, big H10, Nano and Color in these regs is all different
11:07:15amiconnsmall H10 and Nano run the block controller at nearly optimal speed when boosted (but could go faster when not boosted)
11:07:16jhMikeSI did stuff like searching all instances of 0x70000000 throughout with a simple objdump
11:07:27amiconnColor runs it too slow - could go much faster
11:08:03amiconnjhMikeS: I found several places where 0x70008a00 is put into a struct - but I have no idea how to find out where this struct is used
11:08:31amiconn...since the functions which write to this struct get the address passed from somewhere else
11:08:32jhMikeScould be dynamically allocated
11:08:57amiconnSo how could I figure this out?
11:09:21amiconnI guess an emulator would help - but the existing emu is for sansa, and I have no MSVC to poke on it
11:09:30jhMikeSI can't find a formula except to find code that looks like it writes to such a struct.
11:09:40amiconn...and no experience at all with emulator coding
11:09:42jhMikeSyou can download MSVC
11:10:04jhMikeSThe basic one is free and compiles the emu
11:10:07amiconnYes, the 2005 express version - which reportedly doesn't work for compiling the emu
11:10:16amiconnAt least the fs task says so
11:10:19jhMikeSWell, I'm using it must :)
11:10:31jhMikeSYou also need the Platform SDK

11:15:53jhMikeSit will otherwise won't terminate at all
11:16:14amiconnc200 is flash based too, i.e. ata isn't needed, and the lcd is hooked to the mono bridge, not the colour bridge
11:16:37jhMikeSmono bridge? I thought it was a color target.
11:16:47amiconnYes it is, yet it uses the mono bridge
11:17:07amiconn(the one at 0x70003000 which is much simpler and slower than the one at 0x70008a00)

11:20:42ddaltonmy settings aren't been saved on a shut down of my h300.
11:20:47ddaltonanyone know why?
11:20:49amiconnEither it's JdGordon's simple list stuff, or sdoyon's voice callbacks :|
11:21:13*ddalton Hates debugging
11:21:51ddaltonjhMikeS: Well is there a function that is called while recording to save the recording file to disk and what ever else?
11:21:55*amiconn can't think of a good commit message for that threading fix...
11:22:23ddaltonI want to make a quick memo feature. While I hold rec down record but once I let it go just return to what I was doing before.
11:22:26jhMikeSddalton: that's in pcm_record.c
11:22:30ddaltonand this should work from anywhere.
11:23:02Slasheriah, it's that simplelist stuff
11:23:06ddaltonjhMikeS: what should I look for there?
11:23:08jhMikeSddalton: audio_stop_recording does flushing
11:23:12JdGordonSlasheri: which debug menu?
11:23:20Slasherithe main debug screen
11:23:26Slasheriwhen scrolling, it crashes immediately
11:23:50JdGordonwtf? thats a bit odd
11:23:58jhMikeSddalton: I'm not sure why those functions need using outside the recording screen or a recording plugin.
11:24:07amiconnddalton: This cannot work from anywhere. Recording needs lots of stuff set up differently than playback
11:24:07Slasheriat least it's missing the simplelist_info_init
11:24:19Slasheriand initializing directly those parameters, not sure yet if that causes it
11:24:54JdGordonhmm woops.. missed it, but not calling init sholdnt cause it to crasg
11:25:12ddaltonjhMikeS: so could I write something like: while(button ==action_std_rec) {what ever code needs to be executed when recording. if(button !=action_std_rec) {code to kill recording and save.}}?
11:25:56ddaltonamiconn: im going to enter the rec screen and start rec automatically.
11:26:06ddaltonby this one key press so its not a new screen...
11:26:14SlasheriJdGordon: at least voice callback isn't initialized without init
11:26:24Slasherithat might be enough to crash it

15:52:16*stripwax shrugs
15:54:11jhMikeScommunicating with any UI-creating thread through it's own message queue would help in a preemptive environment. would even be good in a touchscreen environment.
15:55:00jhMikeSthat leads to an easy way to have real windows with focus (even better with a touchscreen) :)
15:55:32stripwaxDomonoky - can you recall? didn't you need a specific magic string to be present in the bootloader file somewhere on-disk in order for rbutilqt to work out what version bootloader was installed?
15:56:11bluebrotherIIRC the bootloader version is currently only determined by the log file
15:59:19stripwaxand if there's no file? i recall the idea was to look for the bootloader file on-disk (for those devices for which this is possible) and see if the magic string was present and use that to determine the bl version number
15:59:42stripwaxbut it seems patch isn't committed so I guess that's not possible
16:02:26bluebrotheron Ipod (and Sansa?) it would be possible to read the BL from disc and check / md5sum (my favourite as it would also verify the integrity) it
16:05:11SlasheriJdGordon: of course, then tagcache doesn't need to wait for screen updates
16:05:15stripwaxhm, so rbutil would need to download a new list of md5sums every time there's a new bl build. I think we discussed that last time round and decided a magic string would be better! :)

16:19:04guywithproblemill keep you guys updates as Util is working :) currently downloading a bunch of Themes

16:19:44jhMikeSn1s: I could've told you all that :)
16:19:57stripwaxbertrik - hm, nothing I'm aware of. from experience though rbutil seems much faster at physically unzipping onto the device than the built-in Windows unzip, if you're using that.
16:20:12bluebrotherguywithproblem: you could try installing the bootloader −− put the file in the same folder as rbutilqt.exe and try if autodetection of the ipod works
16:20:20stripwaxbertrik - but potentially every file could change in some way between versions, and rockbox builds don't track the dependencies really

16:55:08n1sNico_P: I can test again a bit later today
16:55:10jhMikeSNico_P: frankly I don't think any target besides PP needs the thread/core strutures in IRAM. It's not accessed very much...even if it were, not much data is accessed.
16:56:39Nico_Phmm actually the only things I removed from iram are buf_ridx and buf_widx. long as codec on COP doesn't need to touch those

17:00:13Nico_Pno, they are managed by the buffering thread now
17:01:17jhMikeSdoes codec read any of that? The buffer might need to use UNCACHED_ADDR because of handle contents. I don't want to cache flush/invalidate all the time there.
17:02:32*jhMikeS supposes that can probably be worried about later
17:02:33Nico_PI'm not sure I understand you fully, but the codec reads the data directly from the buffer by requesting a pointer to it with bufgetdata
17:03:18jhMikeSand the handles are on the buffer, right? not just the audio data.

17:04:52Nico_Pthey are aligned on all builds currently
17:05:23Nico_Ppadded I have no idea, but everything uses sizeof so I think there should be no problem

17:07:22jhMikeSok, then we're might actually be that on PP as well. then some buffer data could be read and written at the uncached alias on PP.

17:10:14 Quit FOAD ("I'll be back")
17:11:21jhMikeSit means that reads and writes aren't held in the processor cache but instead are read and written directly in ram when the uncached alias is used. PP is setup to show both cached and uncached views of RAM depending upon the address offset used.
17:12:45 Quit Shaid ("I will see you, in the end. And I will laugh at your pain...")

17:52:42SoapAve: It is my (incomplete?) understanding of the reasons behind Doby NR that it is to correct for a lacking of the media (here magnetic tape) not of the hardware (the reading heads). ASSuming this is correct you do not need to use Doby NR - as a cassette adapter should not suffer from the "hiss" Doby NR is ment to account for.

17:54:37AveI suppose the ideal placement of the "heads" would be more important and somewhat difficult to achieve, also I dont think that the cassette adapter frequency response is particularly good
17:55:47andresmhhow do you boot into appleos?
17:55:47krazykitandresmh, it's up to you, but that's probably one of the simpler ways.
17:55:56SoapIt should, in theory, be far superior to an FM modulator. The S/N ratio isn't the best with tape, but the frequency response is excellent. Also, some of the nicer cassette-adapters I have seen in stores have an adjustable head.

18:20:31SoapLimerr: The Rockbox bootloader is perfectly capable of loading IPL. Use of the IPL bootloader, while supposedly compatible with Rockbox, is not supported due to it not being Rockbox code, and issues with wether it initializes the hardware properly.

18:23:36SoapKonam: it is not as simple as that. The change which appears to have _exposed_ the problem is one which will not be reverted. The change which _exposed_ the problem was one which was made after reverse engineering the Apple OS, and following that more closely than Rockbox had done before. In other words a correction to Rockbox code appears to have triggered an underlying bug. That underlying bug is what needs to be fixed, not the commit which trigger

18:28:21SoapLimerr: that "neat menu" is the Ipod Linux Bootloader. Mind you you can install it - but we can not help you with Rockbox issues as long as you are using it - because, despite what people think, the bootloader does affect the hardware in ways which can make Rockbox behave differently than if Rockbox's bootloader was used.
18:28:43LloreanPartially reinforced by the fact that evidence at least suggests so far that it's only data read from flash while boosted that's corrupted.
18:28:59jhMikeSroolku: can it not worry about the code formatting for thumbnail right now ?
18:29:37LimerrDoesnt the rockbox bootloader have some ability to launch other os:es such as iPL or AppleOS?

Read the threads - people have identified the last useable daily build - I have on my webspace a series of SVN builds I did to help identify which commit triggered the issue - and the last known-working one is amongst that collection. I honestly don't recall either the address to my collection of builds, nor which version is the "last-known-good", but it should all be in the forum thread.

18:46:55stevenmn1s, Hello. I think there may be a bug with the new MIDI loop.
18:46:56jhMikeSMorey: no, selecting the function to call when setting the mode...vo_draw_frame_full or vo_draw_frame_thumb
18:47:30roolkujhMikeS: the other thing to watch out for is the different buttons when the thumb and full screen are 90 degrees rotated
18:47:31stevenmn1s, I've got a test file right here: stevenm/1.mid">
18:47:47jhMikeSyou just send a message to video to draw a thumbnail
18:47:54stevenmn1s, something ends up corrupting memory and overwriting a struct, which leads to a major crash.
18:48:14MoreyjhMikeS: That sounds good.
18:48:38stevenmn1s, This happens because the file tries to change its tempo on the fly. That causes numberOfSamples to change because of tick()
18:48:44jhMikeSroolku: no button changes are should draw as-is
18:49:37jhMikeSui and buffering will have their own threads...ui on the main thread, buffering on it's own
18:50:26MoreyjhMikeS: Does that mean the user can be interacting while buffering in the background? This would speed things up.
18:50:37roolkuthe button control could get confusing, but lets see how it turns out
18:51:10jhMikeSMorey: sure and you'll be able to view the menu from paused which doesn't seem to work right now
18:51:49jhMikeSroolku: it's _way_ simpler. the UI stuff just makes calls like mpeg_stream_pause/play/stop/seek.
18:51:54MoreyjhMikeS: Nice. Lots a luck! :)
18:52:24jhMikeSpretty close to done with it actually. I just need the buffering straight and should be able to start testing.
18:52:44stevenmn1s, also, because numberOfSamples changes, it may be affecting the foor loop condition in midilay.c (the one taht calls synthSamples)

18:58:15stevenmn1s, numberOfSamples goes from 100something all the way up to 260, then suddenly to 95
18:58:56stevenmn1s, due to tempo events. I guess the logic can't handle that... also, the sample buffer within synth.c is set to 256 max, and then num_samples is multiplied by 4

19:00:18n1sstevenm: I'll look into it more, kind of busy now, I have an exam on tuesday :-/
19:00:24stevenmn1s, when it writes past buffer, it overwrites some structures.. like the pointer to the midi file itself.
19:00:44stevenmn1s, oh, that's fine... i'm just saying the results of what I found. It took a long time
19:01:11stevenmn1s, last night I ported over the whole plugin to be a standalone application just so I could use GDB watchpoints, which apparently don't work in plugins
19:01:30n1shere is one file that now plays with squeaks I tested with revisions prior to the loop/pith bend commit and it was fine and then patched with the loop change and it still played fine so i think it is caused by pitch bend depth
19:01:43stevenmn1s, and when I finally set up the watchpoint, memory alignment was such that it was overwriting a DIFFERENT structure.. then gdb hung.. it sucked :(
19:02:08stevenmn1s, Thanks, will look. It could also be the patch 'prescaler' code also

21:12:34mrkikoIt is using mpa codec for mp3 files...
21:12:34rasherwebguest72: I think there's a setting "Play selected first", which will play the one you selected first, rather than start from the top of the list, but I'm not sure that option does this, or what it does. I'm sort of guessing here
21:13:04andresmhis there a way to play in shuffle mode all the files in a directory from the file browser?

21:14:24***Saving seen data "./dancer.seen"
21:14:40webguest72Yup, play selected first fixes that. Thanks!
21:14:54n1sandresmh: yes you can select it in the context menu
21:15:09rasherwebguest72: I believe that option is on by default, so you probably changed it without knowing what it did
21:15:10n1sor you can turn on shuffle and just start playing a file in the dir
21:15:25markunandresmh: I never use shuffle myself, perhaps there are other ways to do it
21:15:38andresmhit's just that my folder has subfloders
21:15:58andresmhand in the context menu i don't see an "insert suffled" option
21:16:03webguest72Another thing on my gigabeat was that after connecting the usb (while in rockbox) to download files, then disconnecting it
21:16:17n1sandresmh: you can still insert the dir into a playlist, by default all subdirs are inserted too
21:16:37mrkikoDoes the wiki contains some hintgs about the sim' I can't find them...
21:16:40markunn1s: are you sure it's on by default?
21:16:40webguest72and rebooting to rebuild the database my clock setting was gone! (had to reset the time). Also if I plug in the usb while the unit is off
21:16:56n1smarkun: yup, I changed it about a week asgo :-)
21:17:00andresmhoh i found the insert shuffled option now
21:17:09webguest72it will connect to the pc but gets locked up. I had to cycle the battery to recover. connecting while in rockbox avoids this.
21:17:13andresmhwill it create a new playlist?

21:33:54Soapplease read and respect the channel guidelines. On top of that the scrolling margins patch is unofficial and not appropriate subject for conversation in #rockbox. The patch tracker is really a better place. - That being said it is also considered clutter to ask for a sync in the patch tracker - as those who are unwilling/unable to sync are really at the mercy of those who are able/willing. The polite thing to do is sit on your hands and wait for the k
21:33:54Soapindness of others, or to work on syncing the patch yourself. ALL that being said - such rejected features are really a grey area in the #rockbox / #rockbox-community division and perhaps talking about it in the latter (as long as you can keep off topic) is better.

23:13:14rasheror something like that

23:37:44Buschelinteresting.. when you switch off the 14ms-delay in the ipod video's yuv-blit you won't see any artifacts during playback. but of course the framerates will nearly explode for low-res videos (like up to 75fps for 128x96)
23:38:19Buschel...for hi-res videos the fps is only going up little (12.5 -> 12.8 for 320x240)

23:40:51S1gnhi. where to download midi instruments? and what format? can't find that in manual or rockbox website
23:41:54pixelmaS1gn: - all the information you need, I think
23:42:39bluebrotherthe wiki has a link to the patchset download so it's on the website ...

23:45:15bluebrothermakuseru: how are you trying to install the bootloader? Using Rockbox Utility?
23:45:18Mouser_XWell, what's the file date on your current bootloader? (The one on your Gigabeat)
23:45:56makuserulemme check
23:46:28makuserubluebrother: yes
23:46:58bluebrotherwhat method are you using? Are you installing the bootloader separately or using the "Quick Start" tab?
23:47:19Buschelpreglow: could the yielding within the iPod Video's yuv-blit not give cpu-time to the mpeg-decoder?
23:47:52makuserui used the small instalation
23:48:30amiconnBuschel: You can shave off one cycle per pixel from your asm by holding the port address in a register
23:48:37bluebrotherplease try the "Installation" tab
23:48:39makuseruVersion 2.020US
23:50:02amiconnYou might need to do some rearranging in order to not run out of registers though
23:50:57preglow2buschel: only lack of yield() will result in starving the mpeg decoder

23:56:41Buschelamiconn: if you find a way to "find" this one register for loading the port adress please let me know :o) i also searched some minutes...
23:57:44amiconnI'm still not convinced that the general clamping check plus branch over the individual checks is faster than just running the individual checks
23:57:54*amiconn wonders whether jhMikeS tested that
23:58:10amiconnIf you drop the general clamping check, you can free a register
23:58:24makuseruthanks for the help! it works now
23:58:27Buschelbtw, deactivating the 14ms-delay in yuv-blit seems to be not the worst idea. in the worst case the current screen won't be displayed, not relevant for videos and better than being stuck while waiting.
