04:12:52bieberHey
04:13:19JdGordonI created a branch last night for the changes and got almost all the tags converted

04:14:36JdGordonyes
04:14:48JdGordonthe timing is the only unknown
04:14:57bieberOkay
04:15:50bieberSo if you're just going with the existing infrastructure, I'll go ahead and keep on with my original plan and build the Theme Editor from the ground up to use C++ and Qt
04:15:51 Join intrados [0] (~intrados@adsl-99-66-46-18.dsl.wotnoh.sbcglobal.net)
04:16:21JdGordonno, I was hoping to replace the current parser
04:16:28bieberOh, okay
04:16:31JdGordonfixing the existing one to work was simple
04:16:52JdGordonI wanted to do that so your parser has something to compare against?
04:17:02bieberIn that case, I was wondering if there's a wiki doc out there somewhere with code formatting standards for the project?
04:17:23JdGordondocs/CONTRIBUTING in the sources
04:17:27bieberThanks
04:18:26bieberI guess if you're going to use my parser, I'll have to build the parse tree in a static buffer? I was just reading about the no-malloc() rule
04:19:46JdGordonno, malloc is fine if we can replace it in the core
04:19:56bieberOkay
04:20:00JdGordondont rely on free and it can work
04:21:36JdGordondont worry too much about integrating it.. your project is for the editor.. once you have the parser I can help integrate it
04:21:55bieberGot it
04:22:01JdGordonjust keep the parsing and handling seperate :)
04:25:36bieberI've got to run for now, I'm going to read through that formatting doc and get going on the parser tomorrow. The syntax parsing at least should be done pretty quickly
04:26:08JdGordonsweet
04:26:49bieberVerification will take a while, but that's also something that a lot of other people can help out on pretty easily if anyone's up for it, since it's just a matter of putting together the parameter lists

07:08:37S_a_i_n_tJdGordon: I had a look at what you have so-far in the wps from 25954, readability is definitely improved. I must say, it will take me some time to get used to thinking of syntaxes this new way, but at least it won't be a huge effort converting a theme to use the newer syntax. ;)
07:08:58S_a_i_n_tI *think*, well...from what I've seen to date.
07:09:17JdGordonit does add a bit to line lengths though

08:49:29jhMikeSwhich file?
08:49:47kugeluisdl.c & thread-sdl.c
08:50:33jhMikeSthere is a thread is also is the "main" thread and it stay independent from the sdl main thread
08:50:33kugelUnhelpful: but yes, I think there's no real need for that ;)
08:50:58kugelyes, I'm refering to that one with rockbox' main thread
08:51:07kugeland the sdl main thread is the implicit main thread
08:51:44jhMikeSit must be in the pool of rockbox threads. putting the main one there for int simulation would prevent it from working as an async button source
08:52:41kugelI think it must *not* be a rockbox thread?

08:55:32jhMikeSthe one created by the threading during *is* a rockbox thread, "Main". the sdl thread after creating it, jumps into the button loop and serves much like a hardware source of events

08:56:09kugelI need that changed
08:57:23kugelI need to sdl main thread as the rockbox main thread. I think the old main thread can survive but for simplicity I changed to button polling
08:57:30 Quit antil33t ()
08:57:47kugelthe old main thread = the one that enters the button loop
08:58:34kugelis there anything preventing that?
08:59:10kugelmy changes work so far, but I'm maybe not aware of all the implications the current mechanism has
09:00
09:01:58jhMikeSthe main thread is the sdl thread application thread. the "Main" thread is just another rockbox thread like any other created in the scheduler. how can "Main" block and wait for enqueued events as expected then?
09:03:10jhMikeS*sdl application thread* not "sdl thread application thread"
09:03:50kugelI integerate the sdl main thread into the rockbox' threads array
09:04:08kugelwith the only difference that thread->context.t is NULL

09:07:31jhMikeSI guess it's basically the button thing. who wakes up the thread when its blocked? I suppose I'll have to look at your repository to really comment further.
09:08:13kugelnothing wakes it up right now, as I said I went back to polling

09:08:53jhMikeSkugel: ah right, duh
09:08:59kugelthe button thing relies on preemption, which does not work if pth-threads are used (either if sdl is configured for pth threads or if pth-threads are used directly)
09:10:09kugelI can probably create an explicit preemptive SDL (not part of the rockbox threads) to restore the interrupt-like behavior, so I would have basically swapped the main and the button-int thread, but it seems not really needed

10:50:16funmanoops the recording chunk size is 8192 bytes but we're limited to 8188 bytes in DMA transfers :o
10:50:59kugeleh
10:51:25kugel8188 is a strange number
10:51:59funmanit's 32bits * 0x7ff
10:53:33mathwHello. I'm trying to write a theme that uses the new multifont code. The font file in question works perfectly if I select it as the user font from the menu. However, if I try to load it using a %Fl tag in the WPS, the WPS fails to load. The simulator says "Unable to load font 2: '12-Adobe-Helvetica-Bold.fnt'". Could anybody speculate on what might be amiss?
10:53:56jhMikeSfunman: make it 4192 then
10:54:00S_a_i_n_tthe font isn;t present in the sim?

11:19:36LloreanAlexP: I imagine if it was giving that error message then the simulator he's using at least is new enough, right?
11:19:54jhMikeSfunman: you have to implement the to return physical addresses if using DMA with a cache
11:20:00LloreanAlexP: I don't know anything about how multifont works, but would the size of the font be an issue (not enough WPS buffer left or something?)
11:20:35funmanthe what?
11:21:01jhMikeSs/the/it
11:21:22funmanif recording isn't using iram the addresses are flat mapped and dcache entries are dumped
11:21:38S_a_i_n_tLlorean: not enough skin buffer can be a problem
11:21:45S_a_i_n_tbut font size isn;t relative
11:22:18mathwS_a_i_n_t: the line before the font error says "Skin buffer usage: 2824/10240"
11:22:30JdGordonmathw: which target?
11:22:31jhMikeSfunman: it uses the audio buffer. entries may be dumped but looking at cached addresses will "undump" them. the buffer is off limits until the transfer is done.
11:22:38JdGordonand yes, its not enough room to load the font then
11:22:42mathwokay
11:22:44S_a_i_n_tHmmm...ok, well, that's that theory out the window then...
11:23:02mathwJdGordon: Sansa Clip. Not much memory, I now remember.
11:23:23JdGordonif you can build your own copy I can tell you how to fix it
11:23:39AlexPLlorean: I seem to remember it giving that error if it can't find it too
11:23:50LloreanS_a_i_n_t: Why wouldn't font size be an issue? How much space it takes is directly proportional to the size and number of characters.
11:23:57jhMikeSfunman: the beast uses DMA for recording and dma_get_peak_buffer returns the uncached aliases (physical)
11:24:01AlexPBut yes, it seems that size could well be it
11:24:08JdGordonLlorean: no, it is always 10KB for skin fonts
11:24:25mathwSo multifont on the clip is just a no-go then
11:24:30AlexPFor now
11:24:32funmanjhMikeS: i think i don't understand what the function must point to
11:24:40mathwOkay, thanks everyone
11:24:50AlexPYou can increase the buffer (which reduces the amount of memory available for music)
11:24:52S_a_i_n_twait, no...I confused myself, don't listen to me. No, seems there isn't enough room for the font.
11:24:53JdGordonmathw: wait for the next build... ill fix it for you
11:25:14S_a_i_n_tit needs what? 10K for each font?
11:25:15LloreanJdGordon: Ah, is it another LRU cache, or?
11:25:23TorneLlorean: yes
11:25:24JdGordonyes
11:25:26funmanin svn it points to the address which is currently being written by DMA, but on PP it points to the buffer given to pcm_record_more() or pcm_rec_dma_start()
11:25:46mathwJdGordon: I wouldn't want to reduce the music buffer too much...
11:25:56LloreanJdGordon: So the more fonts you use, does it divide space up evenly between them, or do the most used characters stay independently of which font they come from?
11:26:02pamauryJdGordon: does your patch really do something about the different HID modes ?
11:26:21JdGordonLlorean: each font takes a seperate 10KB buffer for its cache
11:26:24JdGordonpamaury: nope
11:26:24jhMikeSfunman: the address the DMA uses, not the virtual address given to the recording calls. I'm just making sure. I've been through the tribulations already. :)
11:26:50pamauryJdGordon: do you think it has to be done in this menu ? The ubs screen already allow the mode selection...
11:27:15JdGordonI tihnk it should, just so the default mode can be set
11:27:21funmanjhMikeS: ok about using physical uncached address, but address of what exactly?
11:27:28JdGordonthat menu doesnt change anything, but it shuold be simple to hook it up

11:32:44jhMikeSfunman: it's in the other drivers for coldfire and the like. it should record the previous position requested, up to the last sample in the current buffer. reset previous position to new buffer when it changes.
11:32:44funmanoh pcm_rec_peak_addr is a global variable
11:32:44funmani must have missed something
11:32:57jhMikeSyeah, that the previous position, where it starts for the next peak calc, DMA's current pos is where the calc ends
11:33:17funmanit's not used in svn but recording seems to work anyway

11:36:56LloreanJdGordon: And it shows color targets too in the build log.
11:37:13kugelnot a fan of wasting 10k just for a tiny subset of targets
11:37:29gevaertskugel: you could, but I'd say that the targets that "suffer" from this are the ones with large screens, which are usually the ones with lots of RAM anyway
11:37:46Lloreangevaerts: Ones with large screens allocate a *lot* more memory to WPS, so don't actually suffer.
11:37:50jhMikeSfunman: it updates in pcm_record_data, pcm_record_more, and uses it in pcm_rec_dma_get_peak_buffer as the current address. pcm_calculate_rec_peaks increments it itself for multiple peak calculations within a particular buffer.
11:37:57JdGordon10K is what? 0.001% of abilable ram?
11:38:05kugelgevaerts: I can't follow that
11:38:07Lloreangevaerts: The problem is actually that the Clip's screen is so tiny (and the WPS buffer is calculated from screen size and bit depth) that it doesn't even have room for one additional font
11:38:24gevaerts"suffer" as in "get 10K that they don't actually need"
11:38:47kugelall 'suffer' equally, not only the ones with the large screens
11:38:54JdGordonno they dont
11:39:00JdGordon10KB from 64MB is SFA
11:39:09JdGordon10KB from 2MB is slighty more than nothing
11:39:23*jhMikeS thinks maybe the global variable arrangement should be rearranged, to make it less confusing.
11:39:32gevaertsBut the 2MB targets are the ones that are likely to need the 10KB more
11:39:37JdGordonyes
11:39:45Lloreangevaerts: Except they generally have smaller fonts anyway.
11:39:53LloreanIt might make sense to scale the font buffer by screen size as well.
11:40:09*S_a_i_n_t_ doesn;t really think so
11:40:09kugelWe shouldn't stop considering ram usage just because there's plenty available
11:40:28LloreanGive the large screen targets more space for larger fonts, and the small screen targets can save RAM since they're not going to be using 18-20 pixel fonts anyway
11:40:57JdGordonsmaller fonts means all the more reasont o want multifont
11:41:01S_a_i_n_t_a small screen target still may want to use numerous fonts, *and* have a nice .sbs/.wps
11:41:11LloreanJdGordon: What do you mean?
11:41:13gevaertsLlorean: maybe
11:41:24gevaertsThat could be a good idea I guess
11:41:26kugelalso, with the ams targets we have targets with large screens but not huge ram (8MB, 4MB of which is available for buffering)
11:41:49LloreanS_a_i_n_t_: Yes, but since memory is allocated *per font* then if you allocate 5kb per font because the actual font size is average, the *number* of fonts isn't important (in fact you can use more fonts, more efficiently)
11:42:03LloreanS_a_i_n_t_: If you want 3 fonts at 10kb per font, it takes twice as much memory even if you aren't using it all because the fonts are tiny
11:42:35S_a_i_n_t_but, you may not want to use a tiny font?
11:43:06gevaertsS_a_i_n_t_: larger fonts will still work
11:43:34LloreanS_a_i_n_t_: Do you really think a significant percentage of users will want a screen that is only able to display 2 or 3 lines of text? While larger fonts can be used, it will be optimized to be more efficient with fonts appropriate to the screen size, that's all.
11:44:08LloreanIt doesn't rule anything out, it just makes certain things more or less efficient based on what are probably more likely scenarios given the physical limitations of the player

11:45:42LloreanTorne: Depends on the font size
11:45:45Torneyes
11:45:50Torneso guess what a typical font size is
11:45:56LloreanIf they're 1bpp, it should be a lot.
11:45:58Tornelike i said, the one cabbie uses might be a good start

11:47:07Torneit is indeed 1bpp
11:47:10JdGordon18 bytes per glyph assuming no extra ovherhead... so lots
11:47:20gevaertsLlorean: we're discussing extra fonts here, so the one from cabbie might be irrelevant
11:47:23Tornethere's a bit more overhead, iirc about 4-8 bytes
11:47:29Tornebecause the font cache is crazy
11:47:41gevaertsLet's assume 32 bytes per glyph to get round numbers
11:47:41Lloreangevaerts: Yes, but for deciding what an "average size" font might be, it's a decent start.
11:47:58Tornegevaerts: it's 10000 bytes, though, so it's not a round size ;)
11:48:00Lloreangevaerts: So that's ~312 glyphs?
11:48:01Torneit's not really 10kB
11:48:29*Torne looksin fontcache to check the overhead also
11:49:10***Saving seen data "./dancer.seen"
11:49:11*gevaerts thinks that the standard latin alphabet in upper- and lowercase, digits, and some punctuation is probably plenty for extra fonts
11:49:26gevaertsso about 75 glyphs would be enough I think
11:49:41Torneit's 7 bytes overhead per glyph
11:49:49Torne(not 8)
11:50:16gevaertsok, so assuming 18 bytes per glyph, 7 bytes overhead, 75 glyphs, we get 1875 bytes
11:50:32Tornei think we can live with <10kB, then
11:51:06Tornethe targets with tiny screens/ram are all flash, right? (apart from archos)
11:51:25Tornefontcache only really sucks hard performance-wise on disks (and not even on all disks then)
11:51:25JdGordondepends on your definition of tiny
11:51:27S_a_i_n_t_safe bet
11:51:28gevaerts5kB gives us 22-sized fonts
11:51:30LloreanTorne: Pretty much
11:51:55TorneJdGordon: also no, you asked the other day if i've done anything about font_load and i haven't ;)
11:52:01gevaertsand 22-sized fonts on the clip are insane if you actually want to display strings that use those 75 glyphs
11:52:01Tornei still hasven't decided what a good thing to do would be
11:52:22*gevaerts votes for 3kB per font on small-mem
11:52:52TorneThis reminds me; do we want to, in fact, increase the main UI font buffer size on targets with huge screens and loads of ram?
11:52:59Torneas a temporary workaround for font_load() being slow
11:53:00S_a_i_n_t_wouldn;t actually finishing dynamic skin-buffer fix this "properly"?

11:53:31Torneand avoid the cache entirely
11:53:44LloreanTorne: But you could allocate is at sizeof(glyph)*65 or something
11:53:56Llorean*it as
11:53:57TorneLlorean: That's true..
11:54:04Tornebut equally, you could do that *now*
11:54:21LloreanThat might improve the situation somewhat, then?
11:54:28Tornehow much you allocate per font is independant from how much you allocate for the skin buffer overall
11:54:34Torneexcept the former has to fit in the latter :)
11:54:55LloreanI mean, according to that guy, the clip had like 8kb of skin buffer free anyway, right?
11:55:07gevaertsTorne: decreasing the font buffer size would also speed up loading I suspect
11:55:11Llorean2824/10240, so 7ish
11:55:28LloreanSo even without the additional 10kb, if we used (glyph)*75, a lot of fonts would load just fine on it
11:55:28Tornegevaerts: you mean the main buffer and font_load problem, or skins?
11:55:33gevaertsfont_load
11:55:39Torneah. well, technically yes, it will
11:55:59Tornepossibly contentuous question: couldn't we just dynamically allocate the main UI font buffer at boot? :)
11:56:23pamauryJdGordon: why did you add a list of USB_* in settings.h but never use it ?
11:56:27LloreanTorne: And then use fontcache only if they switch fonts?
11:56:34TorneLlorean: yah, or for skin fonts
11:56:37LloreanYeah
11:56:42Torneor possibly for targets with small ram
11:56:46LloreanYeah.
11:56:49Tornewe could *only* do this on players with 16mb or more anyway
11:56:52LloreanSo allocate it dynamically, but cap it?
11:56:58LloreanI mean, unifont is *huge*
11:57:19JdGordonpamaury: for the setting
11:57:28*funman thinks 8mb ought to be enough for everyone
11:57:36TorneLlorean: True, it is..
11:57:40pamauryJdGordon: but it's currently unused ?
11:58:51JdGordoni ddint get around to finishing it
11:58:51pamauryok
11:58:51pamauryAnd what is your plan about it ?

11:59:46S_a_i_n_t_Torne: Looking into allocating the the font buffer at boot doesn't sound like a bad road to go down...

12:00:28S_a_i_n_t_and, I have a "small screen" player, and that is my most used font for multifont.
12:00:39TorneS_a_i_n_t_: haha ;)
12:00:45LloreanTorne: 256kb isn't too bad.
12:00:46TorneS_a_i_n_t_: i strongly recommend you find a different one ;)
12:00:52LloreanS_a_i_n_t_: None of the nanos are small screen.
12:00:59LloreanThey're physically small, but they've got a decent number of pixels
12:01:00*JdGordon wants 32bpp fonts!
12:01:09S_a_i_n_t_that and unifont, but I may be an exception..
12:01:29TorneS_a_i_n_t_: by small we mean, 128x64 as on clip
12:01:30Torneor similar
12:01:32Torne:)
12:01:37LloreanThe AJBR, the Clip.
12:01:49LloreanThe H100 is at the top of small / bottom of medium
12:01:58S_a_i_n_t_176x132 is hardly *huge* ;)
12:02:13LloreanNo, but it's twice the vertical resolution of the screens we're talking about.
12:02:15S_a_i_n_t_but, I see your point
12:02:22TorneS_a_i_n_t_: that's three times as many pixels!
12:03:07Torneanyway, a lot of people would probably see a *benefit* from sizing the buffer dynamically, since a lot of the fonts people use are less than 80k :)
12:03:15S_a_i_n_t_three times as many *tiny* pixels ;P
12:03:24*S_a_i_n_t_ waits to be chastised.
12:03:48JdGordonTorne: thing is, its not the size of the cache that is the problem.. its the brainddead loading system.. going by the above numbers it is very unlikely many people would ever need the current 60KB for the main font
12:04:00AlexPS_a_i_n_t_: s/chastised/ignored/ :)
12:04:10pamauryJdGordon: see for the modified patch: http://pastebin.org/224667
12:04:37LloreanTorne: Would it be possible to write the current cache in nvram on shutdown, and just load that on boot?

12:08:54 Quit stoffel (Remote host closed the connection)
12:08:54JdGordonbroadcast*
12:08:54TorneLlorean: yes, you could persist the whole cache, it's one of the optoins we discussed before
12:08:54LloreanTorne: Was it objected to?
12:08:54LloreanIt seems like a really obvious solution for the short term
12:08:54Tornethere's a few minor issues (the cache has a couple of pointers in it at the beginning that would need fixing up)
12:08:54JdGordonyou could NOT save it to nvram
12:08:54Torneand you'd need to know whether the font had changed and so on

14:57:21kugelJdGordon: in audio_finish_load_track() the actual loading happens
14:57:54kugelcoping that part and making sure find_albumart() actually finds the station logos should get you somewhere
14:58:13JdGordonwhat state is the buffer in when the radio is started? how do i know when to release those handles?
14:59:00kugelit's empty, I don't know which state exactly
15:00
15:00:03*JdGordon attempts to open a handle in the fm screen
15:00:34kugelnot sure if there's any magic logic to detect it, but it should be pretty safe to assume that you need to release them when the wps is entered
15:01:06jhMikeSwith playback stopped, the whole engine should be idle and all threads inactive
15:01:21kugelAFAIK there's no way to play audio files without entering the wps at the same time
15:01:47jhMikeSkugel: how does the playback control do it then?

15:04:01kugelI think for playback control there needs to be a current playlist which isn't given when the radio is on (doesn't playback control control the radio then anyway?) pictureflow could be problematic indeed
15:04:14JdGordon-4 file error?
15:04:23*jhMikeS balks that pictureflow can start playback, but not adjust the volume when you get a loud blast after playing something quiet
15:04:39kugelfix it! :)
15:04:57kugelpictureflow should be able to re-use volume in lists feature
15:05:27jhMikeSyou have to go to playback control first
15:05:53jhMikeSoh, pictureflow can jump right back to wps from its menu too. :)

16:14:40gerbilHi all, I've created my first patch for Rockbox. The kaybox plugin now can import data from a text file. For me it's a big improvement as it's totally boring to key in a bigger data base using the few buttons of the device. I'd like to take this opportunity to ask you to roughly scan the patch and give me advice how to improve it. I'd really like to have it included into Rockbox.
16:15:49n1sgerbil: i looked at it breifly, but am a bit busy right now, but will try to take a closer look sometime in the future
16:15:52gerbilSorry, s/kaybox/keybox/
16:16:15gerbilThanx a lot n1s!
16:16:31n1sone thing i though of was to ask the user if they want to delete the unencrypted file and then doing it directly instead of just telling them to do it
16:17:02n1salso, i think your splashes have too long timeouts and also different timeouts
16:17:12gerbilok, I think about it how to do it best
16:17:43gevaertsJust deleting the file won't do much
16:18:47gerbilaccording the splashes, if a line is too long for the data base the user is informed. especially for this message, I had to increase the time to be able to read the full text.
16:19:33gerbil@gevaerts: you are right, I'll change it.
16:20:02*gevaerts will just look for passwords on the raw disk :)
16:21:17gerbilyou want to state I have to overwrite the raw data? That's surely harder to do. there I have no idea how to do it.
16:21:51gevaertsI think it needs to be thought about anyway

17:00:48JdGordonor is <name>.jpg good enough?

20:37:39archivatorHm, I was left with the impression that the plugin buffer is as big as it can possibly be.
20:39:39Torneno. it could be almost the whole of ram, if you wanted
20:39:48Tornebut then there'd be very little for audio buffering :)
20:40:10TorneTher eare some targets where the plugin buffer is already a reasonably large proportion of ram
20:40:18Torneand so making it bigger on those targets would likely be unpopular
20:40:45Tornebut it's target-specific, and the easiest way while you are still developing your plugin is to make it bigger :)
20:42:54Tornewhat target are you actually building for?
20:43:19mtIs is possible to link the standard math library to a codec in a sim build ?
20:46:17gevaertsprobably

20:47:46Tornewell, it's 512kb already on ipodvideo, but you can just make it bigger for now
20:48:04Tornethere's ~28MB of ram free or so, audio buffering won't mnind losing another meg :)
20:48:35Torneyou'll probably have to do something about the size *later*, i doubt anyone's going to eb too thrilled if it needs >512KB plugin buffer when it's *done*.. ;)
20:49:24archivatormake that another 3 megs :) and I will do something about this size, I'm already looking into compression options (not really easy to do right, though)
20:49:47Tornei hope that's data, not code.. ;)
20:50:27archivatorit is. and that's the smallest it gets!
20:51:14Tornewell, data is dealable-with, generally
20:51:22Tornething with giant code are more awkward

20:53:31archivatorlinuxstb: the code is far lighter than festival. The data is virtually the same, actually. Structured differently (i.e., no Scheme!) but more or less the same.
20:53:33Torneit's only fair that making the thing talk is bigger ;)

21:00:08archivatorre: compression - this is my top choice at the moment - http://www.oberhumer.com/opensource/lzo/lzodoc.php
21:00:57archivatorSimple, gpl2, claims to be really fast (haven't done any testing), in-place (!)
21:01:03Tornewell, is compression the answer, though? How small will the data go and still be decompressable quick enough?
21:01:51 Part watto
21:02:08archivatorTorne: no idea, I'm just brainstorming at the moment. However, the voice data can't really be trimmed any more than it already is. I mean, it *is* practically every diphone in the English language..
21:04:32linuxstbWould it make sense to partially load it into a cache, in a similar way to font glyphs?
21:04:44Torneyah, i'm just saying.. it's worth at least trying to compress it to see how generally compressable it is at *all*
21:04:58Torneobviously the rate will vary depending on the technique/algorithm/etc
21:05:21Torneand yeah, what llorean said. does it all need to be in ram at once?

21:09:59markunarchivator: I think espeak would have been smaller :)
21:10:08markun(much smaller)
21:10:15markuntoo bad of the GPL version
21:11:37archivatorlinuxstb: I'm not familiar with the way fonts are handled. The word "partially" scares me, though. If I had access to some enormous corpus and the necessary linguistic skills, I could've in theory rearranged the voice data such that you could speak the most common words from a subset of the voice. But I don't (and I can't), so there's that :)
21:11:56archivatormarkun: trust me, I know. See the report on the wiki page. However, there are other problems with eSpeak.
21:12:27markunbut I really like espeak :)
21:12:38markun(the horrible dutch output was done by me ;)
21:13:00archivatormarkun: really? The default English voice is horrendous imho. C++ doesn't help, either.
21:13:20markunwell, I believe he removed the C++ stuff (at least the templates)

21:21:25archivatorDear $DEITY! 6MB are not enough for this monster. This is *really* strange, considering that the respective x86_64 version is 3.2MB. The rockbox version should be even smaller as I've stripped everything but the library and even removed the other tts engine.
21:22:47mtWhy doesn't the linker complain when I use pow() for example, yet the function behaves incorrectly (just outputs zeros) ? (been working on stuff for 11 hours straight now, can't think anymore tonight !)
21:23:41linuxstbmt: Compiling for a target or the sim? IIRC, SDL has a dependency on libm, so libm is linked with the sim.
21:24:28mtlinuxstb: sim
21:24:31linuxstbDon't ask me why it's returning wrong results though...
21:24:55mtah .. that was my next question
21:26:23linuxstbmt: It sounds like you should return to it tomorrow morning - I am sure it will be clearer then...
21:27:20archivatorHm, I'm rather stupid, really. The 7 MB thing is 'cause the code is really 'bout 3 MB and then another 3 MB are the memory I allocate for tlsf + some wiggle room. Gotta shrink that heap I guess.
21:27:53mtmust .. hear .. sound :(
21:28:20linuxstbmt: So this is the original floating-point code you're trying to get to work?
21:28:37mtYes
21:29:31mtlinuxstb: Everything seems to be working fine now, except for those maths functions which ruin everything
21:32:46linuxstbarchivator: What did you mean in -community by "flite has preliminary utf8 support" ? Rockbox uses utf8...
21:34:22archivatorlinuxstb: It's where I'm headed next, actually. UTF-8 support looks (from a brief investigation) incomplete, I really want to make sure it works before I do anything else (even fixed-point math)
21:34:54archivatorBecause, if it doesn't, that means the voice scripts are unlikely to support it, either, which leaves us in a very bad place.
21:35:29linuxstbWhat encodings does it support?
21:37:53archivatorlinuxstb: that's the thing, I have a strong feeling (still uncomfirmed) that it's just ASCII. Some of the low-level text manipulation functions mention utf, so there's something I'm missing. I really hope it turns out that the phoneme translation is ASCII and everything else is UTF-8 but there's a chance it's far worse.

21:49:06archivatorAh, wonderful. The scripts handle utf8 by well, "exploding it into multiple byte values" (whatever that means). Since the voice data would be in this format, flite would need to do the same. Only, it doesn't. The utf8explode function's there but it's never called. Given how there are no pre-built non-English flite voices out there, I'm kinda at loss.

23:33:32Strife89bertrik: What do you mean, "RDS support"?
23:35:13bertrikStrife89, radio data system, some FM channels send their station name and some other info along with the FM signal, so I mean support for showing that in rockbox on the fm screen
23:35:20 Quit goodnick (Quit: Page closed)
23:35:34kenguestbertrik: do some players even support that?
23:36:19Strife89bertrik: Ah; I suppose I should try and do a design that will allow for this data?
23:36:24bertrikkenguest, there are indeed only a few players where the fm chip supports RDS, basically just the gigabeat s
23:37:00gevaertsbertrik: also the apple fm remote IIUC
23:37:25bertrikStrife89, it's no use really to make a WPS or anything before it's supported in the rockbox core
23:37:32bertrikgevaerts, ah yes, true
23:37:59kenguestbertrik: the cunning plan there would be for those players to save the data, upload it and thus have the info available for the likes of others that don't. that way users of players that don't have RDS could possibly have a list of likely stations to tune into.
23:38:08Strife89bertrik: But it would still be handy to have base WPSs for the next release.
23:38:19kenguestjust a thought!

23:43:28bieberQuick question if any of the GSOC admins are around: do I claim copyright on my code, or assign it to Rockbox? And I'm assuming I should go ahead and copy the standard header files I see in the rest of the Rockbox source?

23:44:26CIA-5New commit by 03alle (r25973): Avoid duplicated code, create a formatting function for FM frequency
23:44:31bieberIs the $Id line auto-generated, or do I need to fill that out?
23:44:49bluebrobieber: that is generated. It"s a keyword substitution done by svn
23:44:54bertrikdon't fill it out
23:45:11bluebrobieber: see http://svnbook.red-bean.com/en/1.4/svn.advanced.props.special.keywords.html for details.
23:45:36bluebrobasically, you can just copy it (no need to adjust a wrong filename) and set the svn:keywords property correctly.
23:45:51bieberOkay, so I'll just write $Id$?

23:47:25bluebroyes, basically. I for one usually just copy an existing Rockbox file header and leave the line as-is.

23:50:04Strife89Time to compile a bunch of sims, then.
23:51:28AlexPkenguest: The info is dynamic, pretty much (song/station info, that sort of thing).
23:51:55AlexPbertrik: And yes, RDS support makes lots of sense now :P (hint hint) :)
23:52:53kenguestAlexP: ah ok. i thought perhaps there'd be usable info there for configuring 'preset radio stations'
23:52:58pixelmaand how would you chose the format type for frequencies? The commit message doesn't tell :\
23:53:37AlexPkenguest: It is also used for things like alternative frequency lists, so it depends where you are
23:53:55kenguestgotcha
23:54:17gevaertsAlexP: there's the unique station identifier as well. That's not dynamic
23:54:18AlexPFor instance (in the UK at least), national radio stations have different frequencies in different parts of the country (so overlap etc. isn't a problem due to limited range)
23:54:44AlexPgevaerts: Yeah, but then you need to tie it to the frequency used for that station in a particular area
23:55:16AlexPFor instance Radio 2 doesn't have just one frequency, it depends if you are in London/Manchester/Cleethorpes/wherever
23:55:40gevaertsSure, but if you're in a location (and let's admit it, most people often are), you could automatically generate a usable preset file for that location
23:55:44AlexPAnyway, the point I'm making is that it is probably easier to do it by hand/get it from existing lists
23:55:46bieberbluebro: JdGordon has been talking about me writing a parser and a verifier for WPS files in C that they could integrate into the theme engine. Should I put my new code in the skin_engine directory of his skinenginebreakbranch, or just open a whole new theme editor directory somewhere and let others modify/integrate it with the rest of the engine?
23:55:46bertrikgevaerts, yeah the station name should be static (but only 8 characters IIRC), the free text that stations send is usually full of non-related info (advertisements etc.)
23:56:02*Strife89 sees no sign of (a) page(s) that list targets with radios.
23:56:06gevaertsbertrik: not the name, the ID. That's different again :)
23:56:30bieberI'd be fine with writing this part in Rockox style C with static buffers and such, if it would make integration easier
23:56:38gevaertsThe PI field
23:57:00bluebrobieber: integrate into the theme engine as in alternate parser for checkwps? (sorry, didn't got around reading the logs)
23:57:33gevaertsbluebro: JdGordon wants to replace the entire wps parser
23:57:44bieberThe impression I get is that he wants to replace the existing parser with mine once it's finished, I'm assuming so that things will stay in sync more easily
23:57:54bertrikStrife89, I made a list once: http://www.rockbox.org/wiki/FmTunerHardware
23:57:58bluebrook. So that parser would become the Rockbox wps parser IIUC?
23:58:05gevaertsyes
