00:48:26dstaleyHey, what are the ways to convert album art to Rockbox supported versions on OS X?
00:48:53LloreanThe same way you convert anything to a jpeg or bitmap.
00:49:44dstaleyWell, when I just resize and convert in Photoshop it doesn't work. I thought my settings were wrong for the WPS, but album art downloaded with a dedicated RB tool worked fine.
00:50:09AndrewRBwhat filename are you giving the file(s)?
00:50:24gevaertswhich version of rockbox are you using?
00:51:51dstaleyAndrewRB: cover.bmp, folder.bmp
00:51:56dstaleygevaerts: 3.2
00:52:31pixelmawhat format do you convert to? Any weird bmp settings, like compression or so?
00:52:34gevaertsdstaley: does photoshop give you options when saving bmp? You don't want rle compression
00:52:42AndrewRBdstaley: could you upload one of the images to imageshack.us and post the link please
00:52:42evilnickAnd they're in the same folder as your music files?

01:27:41dstaleyIt isn't resized, but I am under the impression that Rockbox will automatically resize it?

01:31:40saratogahe said 3.2 above
01:31:56pixelmathat's what I remember too
01:32:06AndrewRByeah, but specific buidl makes a difference, right?
01:32:10saratogaso he needs to use BMP or else update to a recent build
01:32:26LloreanAndrewRB: 3.2 IS a specific build
01:32:30UnhelpfulAndrewRB: 3.2 is *one* specific build.
01:32:31LloreanLater builds aren't 3.2 any more.
01:32:40AndrewRBah, sorry
01:33:11UnhelpfulMajorChanges shows JPEG AA to be post-3.2. 3.3 will be the first *release* to include it.
01:34:38saratogaincidentally, is there a reason we have a users mailing list instead of just using the forums? the list seems essentially redudant, and it brings out the worst in people for some reason

01:41:29safetydanlee321987: no, they're not really API functions anyway
01:41:44JdGordon|Llorean: depends if you call not having all plugins which appear to use the inbuilt menu, having them act the same way
01:42:13LloreanJdGordon|: That's not really a bug. Just aesthetics.
01:42:25LloreanCan't this wait until after the freeze?

(yes, I know I forgot to tracker it - recipe to reproduce: go to e.g. "set background" and actually set a different colour -> on return to the menu, the statusbar will at least have the old background colour, sometimes looks blanked (as if foreground colour was the same too) until the next statusbar update

01:52:28pixelmajust wanted to go get some sleep...
01:52:50JdGordon|thats an odd idea...
01:53:14JdGordon|Llorean: should we think about removeing the debug menu from release builds?
01:53:39LloreanYes
01:53:47LloreanI suggested that with the 3.0 one, but it never happened.

01:54:24LloreanSince we branch for the release, we can always go back and build a copy of the release with the debug menu enabled if there's something in it we *really* want to know.
01:55:42JdGordon|should be easy enough to do... just get the script which does the release bins to set a define we can check... probably can use the same thing for version string
01:56:13LloreanYeah, didn't we release 3.1 without the proper version string?
01:56:34LloreanWe should probably automate it, or at least make the release script prompt for the version number when run or something
01:58:32JdGordon|did it say 3.0?
01:59:53LloreanOne of our releases just had the SVN revision without a version number

02:23:09LloreanYes, it should probably wait.
02:23:21LloreanAt this point, if something's working for release builds it shouldn't be touched until after the branch.
02:24:19funmanThat's what freeze means after all. So it gives a little time to check last uncertainties about this patch
02:25:06LloreanAnd an added bonus - if it has bugs after commit the release is new enough that everyone can just use it until those bugs are fixed. :)

02:51:28r0b-i congratulate you guys for developing Rockbox it is a very nice piece of software
02:51:45LloreanShouldn't the version string just be Date-3.3-SVNRevision or something like that?

02:51:52*Llorean seems to recall it was something like that.
02:52:19JdGordonisnt everything apart from the 3.x redundant?
02:52:36JdGordon"Version: 3.2" is probaly enough

02:53:46LloreanDate is probably redundant though

03:14:32onlysoaaYeah. I think the P2 uses a PMU not found in any current targets.
03:15:04saratogahomeis there a datasheet for it?
03:16:08onlysoaaI think so. Not sure though. If I find anything, I'll post it on the wiki.
03:16:32onlysoaaI recall seeing a specsheet, but I'm not sure if it has all the necessary data.

03:17:02r0b-if i hit Select when i plug my sansa in with Rockbox on it will it wtill charge or no?
03:17:02saratogahomeso adding scans and information would be a good idea if you get a chance
03:17:31onlysoaaThe P2 docs mention a PMU. I think they describe the PCB even better than a scan would.
03:17:53saratogahomeah yes i found them on google
03:18:09onlysoaaThe PMU docs?
03:20:21saratogahomethe schematics
03:20:35saratogahomethe "power block" it mentions doesn't seem to be software controlled
03:20:39onlysoaaAh, the P2's codec isn't supported by any current target either, huh?
03:21:06onlysoaaOh? I guess I could investigate later.
03:21:57onlysoaaI guess it's connected to some GPIO pin for the battery status readings.

03:23:58saratogahome2no i'm wrong theres another chip that looks like its CPU controlled
03:24:22kronfluxtwo questions. firstly, which one is better? the Sansa Fuze, or the e280v2? I have both, but my fuze has a broken screen, so I want to know which you guys think has better hardware(aka: eventually which is better to run rockbox on)
03:24:47kronfluxI assume with it being a v2, its probably better somehow. I dunno how that works.
03:25:56kronfluxbecause right now the only upside to having the e280v2 is that A) the screen works, and B) its an 8 gig instead of my 4?gig fuze. but I dont like the scroll wheel on the e280v2..
03:26:31cool_walking_I don't know the differences, but I don't think "newer is better" is always the case. The hardware might have just been cheaper to produce.

06:26:49tmztthat would make sense if the color issues were per pixel, not in fields (the channels I think onlysoaa is refering to)
06:27:47tmztthat doesn't make any sense with a framebuffer does it
06:28:29onlysoaaHuh? I don't get it...
06:28:55tmztit's not right, I read yesterday that you said only blue was on the whole display
06:29:04onlysoaaThe color issues are most definitely per pixel, and not with the fields being offset. The hues are right; the Rockbox logo is yellow.
06:29:16tmztokay
06:29:26tmztis it packed? do you know the format?

08:08:37bertrikmaybe the e200v2 is a little different in hardware, like no pull-up on the SDA line
08:09:19amiconnUnhelpful: Did you already have a look into that bitmask lookup instead of duplicating info in tagcache?
08:09:55bertrikthe generic i2c driver assumes we can just put a "hard" voltage on the line (normally in i2c, the data and clock lines are open drain and so can either only pull actively low, or let the pin float and let the pull-up make the signal high)
08:10:37amiconnI also wonder whether it's even necessary to optimise 1<<n in tagcache - sh doesn't have it as a single instruction, but with tagcache performing so many other things, just using the subroutine mit not even be noticeable
08:11:07amiconnThe shift-by-n subroutines have an average execution time of 20 cycles, plus call overhead
08:12:49amiconnbertrik: 20 cycles at what clock frequency? The maximum i2c frequency is 400kHz for most devices (for some it's even 100kHz)
08:14:15bertrikthe fm radio in ams sansas can run at 400 kHz, 20 cycles at 248 MHz
08:14:49bertrik20 cycles maybe overclocking it, but it's surprising that 20 cycles works fine for a clip, while an e200v2 needs 500
08:15:05bertrikthat makes me wonder if there's more to it than just some delay
08:15:27Unhelpfultagcache performed decently even with the array-scan version. the function call overhead for 1<<n appeared to be a fair bit of the binsize cost on SH, though, with the switch to char LUTs saving almost as much as the switch to bitmasks did.

08:16:17amiconnbertrik: If your delay loop needs 20 cyles, and it is executed twice per i2c clock period, that makes an i2c clock frequency of ~6MHz, way more than 400kHz...

09:19:08Unhelpfulamiconn: the "duplicate" data could also be generated via a macro. but if a table-based 1<<n is going to be generally faster and smaller than calling the 1<<n function, it seems like something we ought to do.

10:17:20GodEaterdo Rockbox's EQ settings affect the sound output from MpegPlayer at all ?
10:17:31Unhelpfulbut svn blame only says who committed it. which means that the new file will "belong" entirely to whoever commits it. :/

10:21:04Unhelpfulkugel: right, but when a bunch of code is copied to a new file... ugh, that basically means i need to copy everything i get from svn blame into the commit message...
10:21:59kugelthe whole viewports addition is entirely done by linuxstb
10:22:01Unhelpfulkugel: right, but if the code is copied from parts of other files, the only information retained about copyrights of the individual parts is in the commit message or comments. if you make sure to put that information in one of those places.

11:52:25perfectdrugpixelma: thanks. yeah i guess the buttonlabels are the hardest part for me too. it needs a lot of checking for consistency and nice placement. thanks for the cosmetic there. the player creation in inkscape is fun though after all, I'm getting better.
11:52:42pixelmanow I remember, it was part of the idea to label some more things (like reset or microphone hole) and be a bit more precise about it
11:53:20n1scool_walking_: i don't know for certain but i think it's possible but as always messing with the loader in flash is risky
11:53:39pixelmaperfectdrug: no problem, that's the easier part
11:53:48perfectdrugpixelma: aha ok, it's sometimes not that easy to place the labels if you don't own the player
11:54:12cool_walking_n1s: Yes, I thought it would be risky, but it's the only way I can get this 240GB HDD to be useful.
11:54:20Kupo-sorry for asking again, but my connection disconnected last time. Can I access the microphone input and alter the currently playing music output from within a plugin?
11:54:31perfectdrugpixelma: so I think that can be adjusted later most times
11:55:11cool_walking_n1s: So Rockbox doesn't rely on any initing done by the OF bootloader or anything?
11:55:13n1scool_walking_: then i suggest talking to jhMikeS, he's got the most clue about the beast around here i think, haven't seen him in a while though
11:55:37n1scool_walking_: we may very well depend on some of the OF inits but i'm not sure
11:55:54pixelmaperfectdrug: true
11:56:31cool_walking_n1s: thanks
11:59:37n1scool_walking_: i think others would be interested in that too, to get rid of the random reformats and the "file not found" weirdness too
12:00
12:00:29cool_walking_Well, I know others are interested in getting this HDD working in an S.
12:01:22pixelman1s: IIRC it was your idea to label the reset hole in the drawings... my problem was to find out where to stop labelling something - on some players it could be quite a lot (optical in/out, headphone, USB and so on) and where to put all those labels in the drawing
12:01:31pixelmado you have an opinion?
12:14:41n1sthe point about the reset hole was that many users simply didn't know it existed when they needed it
12:15:00n1sa thing like a hp jack on a DAP is pretty obvious IMO
12:15:46n1sbut i am not a graphics or layout person so...
12:16:30Unhelpfulamiconn: using #define BIT_N(n) (1LU << (n)) and replacing the tables is +180, pretty much the same as was saved between the two revisions to tagcache. the version that had shown some binsize improvement, but not as much as the LUT, put the bitwise operation inside a function. perhaps a TEST_BIT_N makes more sense?

12:24:00pixelman1s: hmmm, ok. Usually those are all labelled on the player themselves... I wonder how important that is for other players than the H100/H300s, e.g. the M5 and X5 have a reset hole too but since they also have a hard power off with a button, you never really need it (saw one stuck X5 once where even the hard power off didn't work and had to be reset the other way, that was with the OF though)
12:25:55n1si think including as many useful things as possible is good but if it gets too cluttered i'd skip obvious things like connectors

14:20:48FrankTM_as far as i know that is :p
14:20:53kugelusing cygwin or a VM, most definitely
14:21:07FrankTM_i do it in VM :P

15:45:17LambdaCalculus37Got my video.
15:45:18onlysoaaOh no, I forgot my flyspray username.
15:45:26kugelI'm wondering how solitaire works on them
15:45:29perfectdrugSamsung YH-92x SVGs are up for comments FS #10279
15:46:49pixelmakugel: last time I saw it on amiconn's Mini it worked nicely
15:47:17pyro_maniac1perfectdrug: you should post in forum too
15:47:26kugelthe keymap seems quite different from e200
15:47:27LambdaCalculus37kugel: It works nicely on my video as well.
15:47:34onlysoaaAh hah, got in.
15:47:40perfectdrugpyro_maniac1: will do
15:48:13LambdaCalculus37kugel: That's the best we can get with just a click wheel and a center button. ;)
15:48:17pixelmakugel: well, the Ipods have different keys
15:48:43kugelon the e200, you go up and down using up and down, and toggle through the cards using the wheel
15:49:18kugelthat seems natural to me, I wouldn't even think of inverting that as it seems to be done on ipods
15:50:28pixelmaI would guess the Ipod keymap was first - I don't know what you mean with "toggle through the cards" though
15:51:12kugelgo left and right through the 7 stacks and the upper left stack
15:52:33pixelmadon't forget that on the clickwheel it's easier to accidentally scroll when you want to hit the button
15:53:23kugelthat happens on the fuze too
15:53:31kugelI see no problem for solitaire here
15:54:02kugelit's quite annoying in rockblox, but there should be some (non-working) software solution to prevent that
15:54:44onlysoaaSubmitted a patch for my initial work on the Samsung YP-P2 port: FS #10280
15:55:49kugelonlysoaa: have you tried bitshifting the r and b channels?
15:56:02onlysoaaI would if I knew how. :P
15:56:04kugelso that the least significat bit is dropped
15:56:38pixelmakugel: and another thing - it seems to me that on the Ipods the shortcuts were made one button press things (no combos, I'd prefer them) which can have an influence on what you chose for the other buttons as well
15:56:41kugelonlysoaa: your diff lacks some files, did you svn add them?
15:57:43kugelpixelma: up down and left right could be still swapped without breaking that
15:59:04onlysoaaOh oops!

16:00
16:00:19pixelmanot breaking but maybe it wouldn't be as logical anymore. I think an Ipod owner should tell what feels more natural/intuitive altogether. I withdraw from discussion, but please don't change something that has worked for years just like that
16:01:11kugelpixelma: lol
16:01:29Tornedoes solitaire really need the vertical scroll thing?
16:01:34Tornei.e. selceting cards within a stack?
16:01:42Torneit does the right thing anyway even if you select the wrong card in the sack
16:01:44kugelLambdaCalculus37: http://pastie.org/501636 doesn't that feel more natural?
16:01:46Torneso it seems reundant
16:02:19pixelmaTorne: it also lets you see the cards better if they are a bit too close
16:02:27kugelTorne: no idea, but it seems unlogical that the scroll wheel is doing this vertical scrolling on the ipods
16:02:36pixelmakugel: I don't see what's so funny about it
16:02:47Tornepixelma: it does?
16:03:02kugelI'm a bit surprised that you ask me that. Do you really think I go and just change that?
16:03:10Tornei don't ahve any objection to the scroll wheel being the vertical scrolling, i'm just questioning the need for vertical scrolling at all in solitaire
16:03:33pixelmakugel: you have a habit of changing things a bit to quick sometimes
16:03:38kugelI'm only talking about solitaire btw
16:03:49pixelmayes and?
16:03:56kugelthat was for Torne
16:04:08Torneoh.
16:04:24onlysoaaMkay, I updated my patch.
16:04:31LambdaCalculus37kugel: I would have to try it out to see how it feels.
16:04:39Torneactually i find selection annoying in solitaire at all because the inverted colours on the cards makes it hard to read the suit at a glance
16:04:46kugelLambdaCalculus37: hence I gave you the link to the patch :P
16:04:52onlysoaakugel: Would you know how I can bit shift the R and B channels?
16:05:06Tornei'd much prefer a way of selecting hte stack that didn't invert a card, and actually just selected which stack, and didn't bother with particular cards
16:05:12Tornebut, dunno quite how best to display that
16:05:20pixelmaTorne: when you go through the cards the current one gets a bit more space, on small displays the cards can be so close together that you wouldn't see what they are at all
16:05:51pixelmaotherwise
16:05:59Tornepixelma: hm. i've seen it compress them down together but never change the display based on scrolling, but i have ipodvideo so my screen is huge
16:06:27Torneokay, that makes sense
16:06:43Torne(but i still find the inverted colours annoying) :)

16:07:49onlysoaakugel: Yeah, it seems that I would have to reimplement that function, and use rgb888 instead.
16:09:13onlysoaakugel: The LCD controller right now expects rgb565, but it outputs rgb565 data to the LCD, which expects rgb666.
16:10:05onlysoaaColors screw up if I change the LCD to rgb565 though.
16:10:31kugelonlysoaa: yes, and rockbox doesn't have support for rgb666
16:10:54kugelhence, if you shift r and b, you can a fake-rgb666
16:11:15onlysoaakugel: That's right, so I have to kinda hack the output into fake rgb888.
16:11:34kugelwhy rgb888?
16:11:38onlysoaaThing is, the LCD controller doesn't read rgb666.
16:11:50kugelI thought the lcd wants 666
16:11:59onlysoaaIt reads rgb565 or rgb888.
16:12:40onlysoaaWhat I'm saying is, I can't have rgb666 in the framebuffer. It has to be either rgb565 or rgb888.
16:12:55kugelI guess you want to switch the lcd to 565, or write a 24bit driver :)
16:13:30onlysoaaI tried switching the LCD to 565, but it only messed up the colors more.
16:13:49kugelwhat did it to the colors?
16:14:09kugelalso, what does the D2 do? isn't that 18bit too?
16:14:15onlysoaaGradients and stuff became all fuzzy.
16:15:18onlysoaaNah, the D2's screen accepts rgb888.
16:15:22kugelare you sure you did it correctly? also, you could look what the of does in a disassembly
16:15:36kugelyes, but rockbox can't give rgb888
16:16:34onlysoaaWell Rockbox outputs rgb565, and the LCD controller is set to output at rgb888.
16:16:54kugelso the lcd controller scales it internally?
16:17:04onlysoaaI'm not sure; I think so.
16:17:11onlysoaaI don't have a D2 to test. ;)
16:19:02*kugel finds it weird that setting the lcd to 565 doesn't work
16:19:37onlysoaaWell actually I don't think I can set the LCD. The LCD seems to be hard set.
16:19:50onlysoaaWhat I can set is the format that the LCD controller outputs.
16:20:14kugelahh
16:20:44kugelso the lcd wants 666, but the controller can only do 888 and 565?

16:22:26kugelyou can get to fake-888 with a bit of shifting, but you'll need to change lcd_copy_buffer_rect() I guess
16:22:59onlysoaaYeah...
16:23:04kugelthough, I wonder what the lcd does when it's fed with 888
16:23:49onlysoaaWhat's strange is that the LCD's manual specifies 8 pins per channel, but the P2's sheet shows only six pins per channel attached.
16:24:46kugelonlysoaa: the shift-part shouldn't be too hard. make a struct { char r, char g, char b }, then fill with LCD_RED(*fb_data)<<3 etc,
16:24:53kugelI might be wrong though
16:25:42kugelthat's probably very slow though
16:25:51onlysoaaThe lcd_copy_buffer_rect() I'm looking at is in asm. :P
16:25:57kugelheh

18:04:43domonokyyes, but you still copy MAX_STRING bytes, even when the title string is smaller.
18:07:06r0b-how hard is it to change the speed of my sansa e250 with rockbox?
18:07:08 Join HellDragon [0] (i=jd@24.203.187.22)
18:07:53domonokyr0b-: what speed ?
18:08:18mtI'll strncpy instead of memcpy later. I'm just trying to figure out why this is not working. I tried the last code I sent (the one with only one memcpy) and it still doesn't work for buf[0] and works for buf[2].
18:09:15domonokyand did check the string directly after coping it there ? ie output id3->title after you set it.
18:09:59mtyes. Also, in my stubbed codec (the qulification task) I did this : http://pastebin.com/d4dcb2de8 and it worked.
18:11:13 Quit {phoenix} (Remote closed the connection)
18:12:08domonokyreally ? that would give "CMT" as title and "MT" as artist, as far as i know
18:12:10r0b-i wanna set it to 80mhz
18:12:51domonokyr0b-: you mean the cpu speed ? why do you want todo this ?
18:13:27domonokymt: how big is MAX_STRING ?
18:13:32mtdomonoky : id3v1buf[4][92] .. My understanding is that id3v1buf[0] and id3v1buf[1] are 2 different arrays, or rather id3v1buf[1] would be the address of the 93rd byte
18:13:42mtdomonoky: is 92 bytes
18:14:06mt*MAX_STRING is 92 bytes :)
18:16:24*domonoky goes checking the code.
18:16:58mtdomonoky: And no it gave 'Codec works' as the title and 'MT' as the artist. If it were CMT I wouldn't have submitted the patch as final. :P
18:17:58r0b-well id like to get the best speed :P
18:18:01domonokyoh, you are correct.. id3v1buf behaves different then id3v2buf...
18:18:01r0b-its 30Mhz now
18:18:43domonokyr0b-: rockbox will automatically switch the cpu speed as needed.. so if you set it to always 80Mhz you just waste battery.
18:19:00mtdomonoky: So I guess my computer is mad then ? :D
18:19:52domonokymt: yes, something is strange. :-)
18:21:16domonokyi would suggest to try it with id3v2buf :-)
18:22:26r0b-so it goes to 80 when i play like doom?
18:24:21domonokywhen ever it needs the power.
18:25:11mtdomonoky: I guess it would work .. I just wanted to use id3v1 since RM has only 4 tags for metadata, 3 of which are the ones we'd be interested in, and it's unlikely that a tag would be more than 90 characters long. Using id3v1 just 'looks nicer' :P.
18:26:50domonokymt: yes.. i just dont know what could be wrong. maybe try again with specifiying both indices ie id3v1buf[1][0]. it shouldnt change, but who knows :-)
18:27:07mtAnyways I'll have to leave it at that and go continue studying ..
18:27:13mtdomonoky: I tried :(
18:27:36*domonoky whished fun while studying :-)
18:27:46domonoky-d +s :-)
18:28:24mtdomonoky: Thanks, and thats for your help. :)

18:44:35pixelmaI wonder if it also fixes the inverted icons in the star menu on greyscale (as reported in 8998 which is not entirely fixed although someone closed the report)
18:45:10funmanobo: ask your question
18:45:42pixelmathat status bar thing looks odd too (it just appears sometimes if the statusbar is redrawn, then vanishes if the star menu is redrawn again)
18:46:37kugelyea, it's sort of broken
18:47:08kugelI can't tell why though
18:47:09obofunman: okay, where to begin... :) one of the things I need to do is find the registers used for LCD and MMC/SD access, since they seem to be different. As far as the LCD goes Daniel suggested looking for related strings and following them
18:47:32obobut there are only one or two of those in the bootloader, and they haven't led me anywhere
18:48:35oboCan you suggest other ways to locate the needed registers?

19:18:28pixelmakugel: about FS #10281 - I know it sounds a bit like applying different standards but I don't think removing an unused define at the same time would hurt much, it would be a general cleanup and "standardising" of the star menu. In this case making the removal a different patch seems a bit like overkill to me (works nicely on greyscale btw., the menu isn't "inverted" anymore but it was the only plugin that did this)

22:33:57BryanJacobsonce I have a hybrid encoder that works I'll be sure I understand it well enough to add support to the Rockbox decoder

22:40:15BryanJacobshttp://www.rockbox.org/twiki/bin/view/Main/WavpackHybridSupport
22:40:24Mikachunotlistening: there should be info about building on the wiki
22:40:25BryanJacobsthe lossy part of a hybrid file is itself a valid Wavpack lossy file
22:40:31Mikachuokay, that makes sense
22:40:39Mikachuwhen would you want to put both files on a dap though?
22:40:46BryanJacobsif you want lossless quality
22:40:48funmannotlistening: look on SansaAMS wiki page
22:40:52notlisteningi'll try there
22:40:59BryanJacobsMikachu: no transcoding! Yay!
22:41:08funmanreally this is as simple as ./rockbox/tools/configure
22:41:08BryanJacobsif you run out of space just delete some WVC files
22:41:14Mikachui guess

22:41:43*BryanJacobs has a pair of Ultrasone HFI-750s
22:41:45Mikachui know why lossless is good, but i thought the idea with wv hybrid was you'd have both on your computer and just the lossy one on your dap
22:42:00funmannotlistening: some way has been made since :P
22:42:10*BryanJacobs also hopes to add correction-file support to ffmpeg after this
22:42:12AlexPMikachu: The idea is that you have the option
22:42:13notlisteningyeah i watch every week
22:42:21MikachuAlexP: okay :)
22:42:22evilnickI'd totally use it to have the lossy ones on the dap and would then copy the WVC across if I wanted some albums to be lossless
22:42:23notlisteningyour comming along great
22:43:02BryanJacobsevilnick: that's how I'd use it too, except in reverse (start with everything lossless and then delete the ones I don't have space for)
22:43:02notlisteningas a side note is there anyone here that helps out with the voice tagging development for rockbox?
22:44:46saratogaBryanJacobs: have you figured out how you will handle buffering correction files?
22:44:54notlisteningor anyone know who might be intrested as I know have the SAPI engine running under linux / Mac and anything else that runs WINE
22:45:33BryanJacobssaratoga: not worrying about it yet... I was thinking allowing some kind of distinct buffer regions
22:46:19evilnicknotlistening: What do you mean by "voice tagging development". I don't understand
22:46:26saratogathats something you should hopefully figure out soon, since that will be a large part of your project
22:46:37notlisteningSo nice windows based voices under linux + a raft of languages
22:46:41saratogaporting the correction code itself to rockbox will likely be quite simple in comparison
22:47:24BryanJacobssaratoga: yeah, I just don't want to put the cart before the horse
22:47:39notlisteningif you used the voice tags under rockbox, spoken menus files and navigation for people who can not see the screen or are driving you have to add voice files to the player to get it to speak them
22:47:39BryanJacobsI wrote a harness so I can test the decoder even without Rockbox support for buffering two files
22:48:16saratogado you expect porting the decoder to be very difficult? usually lossless decoders can work in rockbox with little modification
22:48:24notlisteningyou need a text to speech engine to generate these files
22:48:24saratogathough i have not looked at wavpack
22:48:25 Quit dmb (Read error: 113 (No route to host))
22:48:51notlisteningand i have made the MS vpoces accessible in linux and rockbox is an application that can benefit
22:48:55BryanJacobssaratoga: no, I don't, but I'm not just porting a decoder I'm rewriting a decoder
22:48:56saratogai got most of TTA working in an afternoon for instance while learning the codec API (though still need to fix some bugs)
22:48:59funmannotlistening: you have an e200v2, right?
22:49:17BryanJacobsthe current Rockbox code is based on the wavpack-tiny decoder which has no hybrid support
22:49:18notlisteningyeah a 280
22:49:25BryanJacobsthe Wavpack trunk code is a whole different code base
22:49:38notlisteningactually busted that one got a 250 now :P
22:49:52evilnicknotlistening: Ah, I get it. Although I thought that there was a way of generating those voice clips under linux/OSX already. Never mind.
22:49:53saratogayes but most or all of the code should be resusable right?
22:49:53BryanJacobsso I'm basically writing new support for applying the correction bitstream into the wavpack-tiny decoder
22:50:00notlisteningfunman, 240 :P
22:50:09BryanJacobssaratoga: no, they do things in completely different ways
22:50:16BryanJacobsI can reuse some code but not all
22:50:27saratogawhat cannot be reused?
22:50:31BryanJacobsthe tiny decoder is designed for a minimal memory footprint
22:50:36notlisteningyeah your right evilnick but more choice is always better right
22:50:37BryanJacobsit decodes parts of chunks
22:50:44BryanJacobsthe full decoder does a whole chunk at once
22:51:03BryanJacobsalso, seeking needs to get done at some point - the tiny decoder does an imprecise seek
22:51:09saratogais that a serious problem? the format seems to have very little state
22:51:27BryanJacobsthe format has 8 samples worth of state plus the current weight, which is block-wide
22:51:34saratogai would expect that requires some minor refactoring, not a rewrite
22:51:35BryanJacobsnot very much

22:52:17saratogatry to do as little as you have to in order to get playback, then improve from there
22:52:36saratogaif code is inefficient, it can be incrementally improved, just make sure you don't get lost for a month trying to do everything at once
22:52:56saratogayou'll find your work is more fun anyway when people are using it
22:53:02BryanJacobsI kind of want to understand what I'm doing though - I could just slap the whole wavpack decoder into rockbox
22:53:06BryanJacobsand it would most likely work
22:53:08 Quit moos (Read error: 110 (Connection timed out))
22:53:19BryanJacobsbut then I would lose all the work that went into optimizing the rockbox version
22:53:41BryanJacobsI'd really rather understand exactly what needs to be ported and how it works first
22:54:04saratogathats not a bad first approach actually, the two codecs can be merged in that order if you prefer
22:54:27BryanJacobsat any rate, with the progress I'm making I'll have hybrid decoding by the end of the week
22:54:39BryanJacobsI mean around next Sunday the 14th
22:54:43saratogaeven if codecs are written differently, its often not very hard to move large blocks of code between them (WMA for instance now uses large bits of the Vorbis decoder because they were already well optimized)
22:54:46BryanJacobsso I've got plenty of time to deal with the buffering
22:54:50saratogagreat :)
22:55:19BryanJacobswait wait wait...
22:55:31BryanJacobsyou mean port a wavpack-full codec?
22:55:48saratogayou're going to port a lot of the full wavepack decoder regardless
22:55:58BryanJacobslike, milestones: 1) make a "wavpack-full" that's only used for hybrid files with correction info present 2) implement two-file buffering 3) port things into the tiny wavpack decoder
22:56:03domonokynotlistening: you can try rbutil in wine, and see if sapi voice generation works in this combination :-)
22:56:24saratogawell you should ask your mentor about this, but that approach has its merits in my opinion
22:56:34BryanJacobslinuxstb: thoughts?
22:57:07BryanJacobsI'm not sure it's accurate that I'd be porting "a lot" of the full decoder
22:57:15saratogai haven't looked at the code though
22:57:17BryanJacobsit has support for things like five-channel audio and 24-bit storage types
22:57:31saratogaif the full encoder unsuitable (perhaps includes a lot of malloc or fp) then it may not be worthwhile
22:57:44BryanJacobsit has no fp at all actually
22:57:52BryanJacobsWavpack is an integer only format
22:58:07notlisteningdomonoky, of course i ahve the perfect setup for that
22:59:32BryanJacobssaratoga: hmm, bears some thought
22:59:55BryanJacobsI'll see what happens if I port libwavpack and slap a wrapper around it

23:00:10notlisteningdomonoky, Will come back to you in a bit after installing and testing

23:05:39Chestetahello, I was wondering about patch 10185, does that modify the bootloader code at all or is it just the installer?
23:06:33domonokyChesteta: thats just for the userfriendly install.
23:09:14saratogaBryanJacobs: diffing the full and tiny decoders, they seem very similar
23:09:23saratogamost of the functions in the tiny decoder are also in the full decoder
23:09:51funmanChesteta: installer
23:10:19Chestetaok, thanks domonoky: i was going to test out 10048, should I rebuild the bootloader with that or not :/ it was mentioned above but said its "optional"... could it affect the blue lines when boosted? (had blue lines on the last patch (yesterday) but there is a new one now)
23:11:20BryanJacobssaratoga: yes, the full decoder is a superset of the functionality of the tiny
23:11:39BryanJacobsI should be able to do the full-decoder port you suggested
23:11:50BryanJacobsit sounds like a good thing to do as an experiment at the least
23:12:28saratogayeah
23:12:52 Quit evilnick ("http://www.mibbit.com ajax IRC Client")
23:13:06saratogaanother way to go about it would be to start with the standalone full decoder and merge back in all the tiny decoder code, then port them to rockbox
23:13:11domonokyChesteta: its probably better to also rebuild the bootloader, to make sure everything is ok.
23:13:15saratogasorry i'm not much help deciding how to do it
23:13:23BryanJacobssaratoga: eww, that sounds icky
23:13:33BryanJacobsI think I like starting with tiny and porting the hybrid support better

23:14:12saratogathough some formats (AC3) actually decode 5 channel audio and downmix to 2 channel
23:14:22BryanJacobsditto 24-bit sound and IEEE floating point
23:14:46saratogaare those really difficult to support?
23:14:49ChestetaFunman: are the lines (when boosted) a part of/issue with 10048 or is that due to somehting else?
23:14:51saratogadecoding 24 bit files would be nice
23:14:57BryanJacobsthey're more code in the fastpath
23:15:05BryanJacobswhat do we do, dither into 16 bits?
23:15:07funmanChesteta: i don't know
23:15:38BryanJacobshmm. Maybe the full decoder will be realtime on modern targets anyhow
23:15:44Chestetaok, ill test on e280v2 in a min
23:15:54saratogadithering can be enabled, but the DSP pipeline actually operates on 32 bit ints anyway
23:16:03saratogaso if you can output 24 bit samples it makes sense to do so
23:16:04 Quit Thundercloud (Remote closed the connection)
23:16:25BryanJacobsbtw, about AC3: it makes sense to have 5.1 in it b/c DVDs are muxed that way; nobody has a Wavpack source that comes with multichannel audio
23:16:47AlexPBryanJacobs: That was quick! :)
23:16:52BryanJacobsI didn't know the DSP took more than 16 bits/channel
23:17:10BryanJacobsAlexP: I didn't have to go look anything up to know where I stood :-P
23:17:18AlexPgood news :)
23:17:57domonokyBryanJacobs: about the buffering thing: what happend to the idea of interleaving (on load) those two files ?
23:18:10saratogathe native integer type for CF/ARM is 32 bit so it'd actually be slower to use 16 bit ints
23:18:22saratogaplus having more precision is useful for DSP effects
23:18:24BryanJacobsdomonoky: I found out we don't decode whole blocks at once
23:18:52domonokyah, so interleaving is not really possible ?
23:18:59BryanJacobsdomonoky: it's possible
23:19:04mcuelenaerehmm anyone able to explain what _backlight_on_isr() & friends do? (part of HW PWM backlight fading) Most targets seem to #define it to _set_backlight_on()..
23:19:13BryanJacobsit's just that the block boundaries are part of the wavpack format, right?
23:19:26BryanJacobsso if we do interleaving on load the buffer code has to understand wavpack
23:19:42BryanJacobswhich means it's not generic enough to be used for, say, MIDI patchfiles
23:20:22 Join Thundercloud [0] (i=thunderc@persistence.flat.devzero.co.uk)
23:20:23*domonoky images something like a format specific loader.
23:20:30BryanJacobsthe "generic" way to do that interleaving would be to have a callback in the codec to say "switch files here" when it hits some byte sequence/trigger
23:20:39*BryanJacobs is beaten to the punch by domonoky
23:20:58domonoky:-)
23:21:20BryanJacobswhat are people's thoughts on per-codec buffering code?
23:22:14saratogaBryanJacobs: does the tiny decoder not do 24 bit files? the spec implies that interally everything is 24 bit and 16 bit files are zero padded
23:22:33pixelmadomonoky: you own an m200, right? Could you have a look at the recently added m200 drawings and tell me which part of the volume button is down and which up?
23:22:57BryanJacobssaratoga: there are "optimizations" which say they only work on 16-bit stereo code, according to the comments in the full-decoder source
23:23:29saratogaah ok that makes sense
23:23:55BryanJacobssaratoga: see function decorr_stereo_pass_i
23:24:25amiconnUnhelpful: I was thinking about adding the BIT_N() thing to firmware/ and use it wherever possible in core code at least
23:24:27domonokypixelma: right side of the switch is +
23:24:37BryanJacobsunpack.c line 1018
23:25:04amiconnThe implicit TEST_* would make this more difficult. Not all places using 1<<n use it for (immediate) tests
23:25:34pixelmadomonoky: thanks
23:26:14amiconnmcuelenaere: The _isr() variant only switches part of the backlight circuit - the part that needs to be switched fast for software pwm
23:27:07BryanJacobssaratoga: oh also, you can have 32-bit integer wavpack files
23:27:13mcuelenaerebut these parts only get used upon *hardware* pwm?
23:27:14amiconnThis is needed on ipod video and nano, which have both a software controlled hardware pwm (for brightness), and use software pwm for fading (because the hardware pwd only has a few steps)
23:27:29mcuelenaereohh ok
23:27:50amiconnThe _isr() variants only switch the actual backlight power, but leave the hardware pwm circuit running

23:34:06notlisteningany particular firmware to use?
23:34:31funmanfor patching AMS bootloader? no.
23:34:44amiconnI'm not sure. The only method I know quite well (since I refined its implementation) is software pwm. I thought about the sw setting method, but didn't want to implement it because the brightness would need really many steps to make it look good, and all targets back then had <= 32 steps
23:35:21amiconnWhile this might sound a lot, not all steps are usable for fading unless the user has his backlight set to max. brightness (which is rather unlikely)
23:35:32notlisteningok fingers crossed, any work being done on USB?
23:36:01amiconnI don't know which targets use one of the last two methods
23:36:10funmanthere is doc for a maybe similar chip but noone worked on it yet
23:36:15*hillshum only sets brightness to max when outside
23:37:09*amiconn usally sets brihtness to less than half on the targets with brightness control (e.g. H300, X5)

23:50:51domonokypano: the waveing was for you, everything else not :-)
23:51:31amiconnIt would be possible, but it would need to be a separate option in configure. It wouldn't be too difficult to implement: it just requires starting the sapi_voice.vbs "server" via the 64 bit version of cscript.exe
23:51:42panodomonoky: :-) k at least you now know, what my "problem" is about :-D
23:51:52amiconnThis is possible from a 32 bit process (i.e. cygwin) via the 'sysnative' virtual directory
