| 04:14:36 | JdGordon | yes |
| 04:14:48 | JdGordon | the timing is the only unknown |
| 04:14:57 | bieber | Okay |
| 04:15:50 | bieber | So 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 |

| 04:16:28 | bieber | Oh, okay |
| 04:16:31 | JdGordon | fixing the existing one to work was simple |
| 04:16:52 | JdGordon | I wanted to do that so your parser has something to compare against? |
| 04:17:02 | bieber | In that case, I was wondering if there's a wiki doc out there somewhere with code formatting standards for the project? |
| 04:17:23 | JdGordon | docs/CONTRIBUTING in the sources |
| 04:17:27 | bieber | Thanks |
| 04:18:26 | bieber | I 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 |
| 04:19:46 | JdGordon | no, malloc is fine if we can replace it in the core |
| 04:19:56 | bieber | Okay |
| 04:20:00 | JdGordon | dont rely on free and it can work |
| 04:21:36 | JdGordon | dont worry too much about integrating it.. your project is for the editor.. once you have the parser I can help integrate it |
| 04:21:55 | bieber | Got it |
| 04:22:01 | JdGordon | just keep the parsing and handling seperate :) |
| 04:25:36 | bieber | I'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 |
| 04:26:08 | JdGordon | sweet |
| 04:26:49 | bieber | Verification 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 |

| 08:48:07 | kugel | I'm about to change that for RaaA, i.e. use the implicit main thread for the rockbox' main thread. I currently went back to button polling but I think the interrupt-like fashion can stay if needed |

| 08:49:29 | jhMikeS | which file? |
| 08:49:47 | kugel | uisdl.c & thread-sdl.c |
| 08:50:33 | jhMikeS | there is a thread is also is the "main" thread and it stay independent from the sdl main thread |
| 08:50:33 | kugel | Unhelpful: but yes, I think there's no real need for that ;) |
| 08:50:58 | kugel | yes, I'm refering to that one with rockbox' main thread |
| 08:51:07 | kugel | and the sdl main thread is the implicit main thread |
| 08:51:44 | jhMikeS | it 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 |
| 08:52:41 | kugel | I think it must *not* be a rockbox thread? |

| 08:55:32 | jhMikeS | the 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 |

| 08:57:47 | kugel | the old main thread = the one that enters the button loop |
| 08:58:34 | kugel | is there anything preventing that? |

| 09:00 |
| 09:01:58 | jhMikeS | the 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? |

| 09:08:59 | kugel | the 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) |
| 09:10:09 | kugel | I 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 |

| 10:50:59 | kugel | eh |
| 10:51:25 | kugel | 8188 is a strange number |
| 10:51:59 | funman | it's 32bits * 0x7ff |
| 10:53:33 | mathw | Hello. 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? |
| 10:53:56 | jhMikeS | funman: make it 4192 then |
| 10:54:00 | S_a_i_n_t | the font isn;t present in the sim? |
| 10:54:13 | jhMikeS | err, 4096 |
| 10:54:24 | funman | jhMikeS: i'll just change the as3525 driver i guess |
| 10:54:45 | jhMikeS | I thought it was limited ?? |

| 11:19:04 | JdGordon | which target? |
| 11:19:19 | funman | jhMikeS: hm perhaps there is a problem with pcm_rec_dma_get_peak_buffer() because pcm_callback_more_ready() isn't called before transfers are finished |
| 11:19:36 | Llorean | AlexP: I imagine if it was giving that error message then the simulator he's using at least is new enough, right? |
| 11:19:54 | jhMikeS | funman: you have to implement the to return physical addresses if using DMA with a cache |
| 11:20:00 | Llorean | AlexP: 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?) |
| 11:20:35 | funman | the what? |
| 11:21:01 | jhMikeS | s/the/it |
| 11:21:22 | funman | if recording isn't using iram the addresses are flat mapped and dcache entries are dumped |
| 11:21:38 | S_a_i_n_t | Llorean: not enough skin buffer can be a problem |
| 11:21:45 | S_a_i_n_t | but font size isn;t relative |
| 11:22:18 | mathw | S_a_i_n_t: the line before the font error says "Skin buffer usage: 2824/10240" |
| 11:22:30 | JdGordon | mathw: which target? |
| 11:22:31 | jhMikeS | funman: 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. |
| 11:22:38 | JdGordon | and yes, its not enough room to load the font then |
| 11:22:42 | mathw | okay |
| 11:22:44 | S_a_i_n_t | Hmmm...ok, well, that's that theory out the window then... |
| 11:23:02 | mathw | JdGordon: Sansa Clip. Not much memory, I now remember. |
| 11:23:23 | JdGordon | if you can build your own copy I can tell you how to fix it |
| 11:23:39 | AlexP | Llorean: I seem to remember it giving that error if it can't find it too |
| 11:23:50 | Llorean | S_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. |
| 11:23:57 | jhMikeS | funman: the beast uses DMA for recording and dma_get_peak_buffer returns the uncached aliases (physical) |
| 11:24:01 | AlexP | But yes, it seems that size could well be it |
| 11:24:08 | JdGordon | Llorean: no, it is always 10KB for skin fonts |
| 11:24:25 | mathw | So multifont on the clip is just a no-go then |
| 11:24:30 | AlexP | For now |
| 11:24:32 | funman | jhMikeS: i think i don't understand what the function must point to |
| 11:24:40 | mathw | Okay, thanks everyone |
| 11:24:50 | AlexP | You can increase the buffer (which reduces the amount of memory available for music) |
| 11:24:52 | S_a_i_n_t | wait, no...I confused myself, don't listen to me. No, seems there isn't enough room for the font. |
| 11:24:53 | JdGordon | mathw: wait for the next build... ill fix it for you |
| 11:25:14 | S_a_i_n_t | it needs what? 10K for each font? |
| 11:25:15 | Llorean | JdGordon: Ah, is it another LRU cache, or? |
| 11:25:23 | Torne | Llorean: yes |
| 11:25:24 | JdGordon | yes |
| 11:25:26 | funman | in 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() |
| 11:25:46 | mathw | JdGordon: I wouldn't want to reduce the music buffer too much... |
| 11:25:56 | Llorean | JdGordon: 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? |
| 11:26:02 | pamaury | JdGordon: does your patch really do something about the different HID modes ? |
| 11:26:21 | JdGordon | Llorean: each font takes a seperate 10KB buffer for its cache |
| 11:26:24 | JdGordon | pamaury: nope |
| 11:26:24 | jhMikeS | funman: 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. :) |
| 11:26:50 | pamaury | JdGordon: do you think it has to be done in this menu ? The ubs screen already allow the mode selection... |
| 11:27:15 | JdGordon | I tihnk it should, just so the default mode can be set |
| 11:27:21 | funman | jhMikeS: ok about using physical uncached address, but address of what exactly? |
| 11:27:28 | JdGordon | that menu doesnt change anything, but it shuold be simple to hook it up |

| 11:36:56 | Llorean | JdGordon: And it shows color targets too in the build log. |
| 11:37:13 | kugel | not a fan of wasting 10k just for a tiny subset of targets |
| 11:37:29 | gevaerts | kugel: 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 |
| 11:37:46 | Llorean | gevaerts: Ones with large screens allocate a *lot* more memory to WPS, so don't actually suffer. |
| 11:37:50 | jhMikeS | funman: 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. |
| 11:37:57 | JdGordon | 10K is what? 0.001% of abilable ram? |
| 11:38:05 | kugel | gevaerts: I can't follow that |
| 11:38:07 | Llorean | gevaerts: 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 |
| 11:38:24 | gevaerts | "suffer" as in "get 10K that they don't actually need" |
| 11:38:47 | kugel | all 'suffer' equally, not only the ones with the large screens |
| 11:38:54 | JdGordon | no they dont |
| 11:39:00 | JdGordon | 10KB from 64MB is SFA |
| 11:39:09 | JdGordon | 10KB 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. |
| 11:39:32 | gevaerts | But the 2MB targets are the ones that are likely to need the 10KB more |
| 11:39:37 | JdGordon | yes |
| 11:39:45 | Llorean | gevaerts: Except they generally have smaller fonts anyway. |
| 11:39:53 | Llorean | It 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 |
| 11:40:09 | kugel | We shouldn't stop considering ram usage just because there's plenty available |
| 11:40:28 | Llorean | Give 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 |
| 11:40:57 | JdGordon | smaller fonts means all the more reasont o want multifont |
| 11:41:01 | S_a_i_n_t_ | a small screen target still may want to use numerous fonts, *and* have a nice .sbs/.wps |
| 11:41:11 | Llorean | JdGordon: What do you mean? |
| 11:41:13 | gevaerts | Llorean: maybe |
| 11:41:24 | gevaerts | That could be a good idea I guess |
| 11:41:26 | kugel | also, with the ams targets we have targets with large screens but not huge ram (8MB, 4MB of which is available for buffering) |
| 11:41:49 | Llorean | S_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) |
| 11:42:03 | Llorean | S_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 |
| 11:42:35 | S_a_i_n_t_ | but, you may not want to use a tiny font? |
| 11:43:06 | gevaerts | S_a_i_n_t_: larger fonts will still work |
| 11:43:34 | Llorean | S_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. |
| 11:44:08 | Llorean | It 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 |

| 11:45:21 | funman | someone can try http://www.rockbox.org/tracker/task/11257 on AMSv1 ? all my other sansas are busy benchmarking a clock change |
| 11:45:24 | Torne | relevant question: for the typical fonts used on the players with tiny screens, say, the one cabbie uses for a start.. |
| 11:45:25 | * | jhMikeS thinks even more functionality can be moved up into pcm.c |
| 11:45:31 | Torne | how many glyphs fit into 10kB? |
| 11:45:32 | * | Llorean just doesn't like when the first reaction to a problem is "Throw more RAM at it, and it'll be fine" |
| 11:45:36 | Torne | or 5kB? |
| 11:45:42 | Llorean | Torne: Depends on the font size |
| 11:45:45 | Torne | yes |
| 11:45:50 | Torne | so guess what a typical font size is |
| 11:45:56 | Llorean | If they're 1bpp, it should be a lot. |
| 11:45:58 | Torne | like i said, the one cabbie uses might be a good start |
| 11:46:32 | S_a_i_n_t_ | 12 helvetica appears "standard" |
| 11:46:34 | | Join LinusN [0] (~linus@rockbox/developer/LinusN) |
| 11:46:48 | JdGordon | 12*12/8 per font? |
| 11:46:52 | Llorean | Torne: A good idea might be to say "we should try to fit X number of glyphs from the cabbie font" and go from there? |
| 11:47:07 | Torne | it is indeed 1bpp |
| 11:47:10 | JdGordon | 18 bytes per glyph assuming no extra ovherhead... so lots |
| 11:47:20 | gevaerts | Llorean: we're discussing extra fonts here, so the one from cabbie might be irrelevant |
| 11:47:23 | Torne | there's a bit more overhead, iirc about 4-8 bytes |
| 11:47:29 | Torne | because the font cache is crazy |
| 11:47:41 | gevaerts | Let's assume 32 bytes per glyph to get round numbers |
| 11:47:41 | Llorean | gevaerts: Yes, but for deciding what an "average size" font might be, it's a decent start. |
| 11:47:58 | Torne | gevaerts: it's 10000 bytes, though, so it's not a round size ;) |
| 11:48:00 | Llorean | gevaerts: So that's ~312 glyphs? |
| 11:48:01 | Torne | it'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 |
| 11:49:26 | gevaerts | so about 75 glyphs would be enough I think |
| 11:49:41 | Torne | it's 7 bytes overhead per glyph |
| 11:49:49 | Torne | (not 8) |
| 11:50:16 | gevaerts | ok, so assuming 18 bytes per glyph, 7 bytes overhead, 75 glyphs, we get 1875 bytes |
| 11:50:32 | Torne | i think we can live with <10kB, then |
| 11:51:06 | Torne | the targets with tiny screens/ram are all flash, right? (apart from archos) |
| 11:51:25 | Torne | fontcache only really sucks hard performance-wise on disks (and not even on all disks then) |
| 11:51:25 | JdGordon | depends on your definition of tiny |
| 11:51:27 | S_a_i_n_t_ | safe bet |
| 11:51:28 | gevaerts | 5kB gives us 22-sized fonts |
| 11:51:30 | Llorean | Torne: Pretty much |
| 11:51:55 | Torne | JdGordon: also no, you asked the other day if i've done anything about font_load and i haven't ;) |
| 11:52:01 | gevaerts | and 22-sized fonts on the clip are insane if you actually want to display strings that use those 75 glyphs |
| 11:52:01 | Torne | i still hasven't decided what a good thing to do would be |
| 11:52:22 | * | gevaerts votes for 3kB per font on small-mem |
| 11:52:52 | Torne | This reminds me; do we want to, in fact, increase the main UI font buffer size on targets with huge screens and loads of ram? |
| 11:52:59 | Torne | as a temporary workaround for font_load() being slow |
| 11:53:00 | S_a_i_n_t_ | wouldn;t actually finishing dynamic skin-buffer fix this "properly"? |
| 11:53:12 | Torne | S_a_i_n_t_: not really |
| 11:53:20 | funman | ranma: does http://pastie.org/956757 have an effect on power usage? |
| 11:53:20 | Torne | you still nede to allocate *some* fixed size per font |
| 11:53:27 | Torne | unless you are going to allocate sizeof(entire font) |
| 11:53:31 | Torne | and avoid the cache entirely |
| 11:53:44 | Llorean | Torne: But you could allocate is at sizeof(glyph)*65 or something |
| 11:53:56 | Llorean | *it as |
| 11:53:57 | Torne | Llorean: That's true.. |
| 11:54:04 | Torne | but equally, you could do that *now* |
| 11:54:21 | Llorean | That might improve the situation somewhat, then? |
| 11:54:28 | Torne | how much you allocate per font is independant from how much you allocate for the skin buffer overall |
| 11:54:34 | Torne | except the former has to fit in the latter :) |
| 11:54:55 | Llorean | I mean, according to that guy, the clip had like 8kb of skin buffer free anyway, right? |
| 11:55:07 | gevaerts | Torne: decreasing the font buffer size would also speed up loading I suspect |
| 11:55:11 | Llorean | 2824/10240, so 7ish |
| 11:55:28 | Llorean | So even without the additional 10kb, if we used (glyph)*75, a lot of fonts would load just fine on it |
| 11:55:28 | Torne | gevaerts: you mean the main buffer and font_load problem, or skins? |
| 11:55:33 | gevaerts | font_load |
| 11:55:39 | Torne | ah. well, technically yes, it will |
| 11:55:59 | Torne | possibly contentuous question: couldn't we just dynamically allocate the main UI font buffer at boot? :) |
| 11:56:23 | pamaury | JdGordon: why did you add a list of USB_* in settings.h but never use it ? |
| 11:56:27 | Llorean | Torne: And then use fontcache only if they switch fonts? |
| 11:56:34 | Torne | Llorean: yah, or for skin fonts |
| 11:56:37 | Llorean | Yeah |
| 11:56:42 | Torne | or possibly for targets with small ram |
| 11:56:46 | Llorean | Yeah. |
| 11:56:49 | Torne | we could *only* do this on players with 16mb or more anyway |
| 11:56:52 | Llorean | So allocate it dynamically, but cap it? |
| 11:56:58 | Llorean | I mean, unifont is *huge* |
| 11:57:19 | JdGordon | pamaury: for the setting |
| 11:57:28 | * | funman thinks 8mb ought to be enough for everyone |
| 11:57:36 | Torne | Llorean: True, it is.. |
| 11:57:40 | pamaury | JdGordon: but it's currently unused ? |
| 11:58:51 | JdGordon | i ddint get around to finishing it |
| 11:58:51 | pamaury | ok |
| 11:58:51 | pamaury | And what is your plan about it ? |
| 11:58:51 | | Part LinusN |
| 11:58:51 | Torne | it would still be nice to actually fix font cache loading to not suck, of course :) |

| 12:00:39 | Torne | S_a_i_n_t_: haha ;) |
| 12:00:45 | Llorean | Torne: 256kb isn't too bad. |
| 12:00:46 | Torne | S_a_i_n_t_: i strongly recommend you find a different one ;) |
| 12:00:52 | Llorean | S_a_i_n_t_: None of the nanos are small screen. |
| 12:00:59 | Llorean | They're physically small, but they've got a decent number of pixels |
| 12:01:00 | * | JdGordon wants 32bpp fonts! |
| 12:01:09 | S_a_i_n_t_ | that and unifont, but I may be an exception.. |
| 12:01:29 | Torne | S_a_i_n_t_: by small we mean, 128x64 as on clip |
| 12:01:30 | Torne | or similar |
| 12:01:32 | Torne | :) |
| 12:01:37 | Llorean | The AJBR, the Clip. |
| 12:01:49 | Llorean | The H100 is at the top of small / bottom of medium |
| 12:01:58 | S_a_i_n_t_ | 176x132 is hardly *huge* ;) |
| 12:02:13 | Llorean | No, but it's twice the vertical resolution of the screens we're talking about. |
| 12:02:15 | S_a_i_n_t_ | but, I see your point |
| 12:02:22 | Torne | S_a_i_n_t_: that's three times as many pixels! |
| 12:03:07 | Torne | anyway, 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 :) |
| 12:03:15 | S_a_i_n_t_ | three times as many *tiny* pixels ;P |
| 12:03:24 | * | S_a_i_n_t_ waits to be chastised. |
| 12:03:48 | JdGordon | Torne: 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 |
| 12:04:00 | AlexP | S_a_i_n_t_: s/chastised/ignored/ :) |
| 12:04:10 | pamaury | JdGordon: see for the modified patch: http://pastebin.org/224667 |
| 12:04:37 | Llorean | Torne: Would it be possible to write the current cache in nvram on shutdown, and just load that on boot? |
| 12:04:44 | JdGordon | queue_broadcase probably isnt the best wya to do it |
| 12:08:54 | | Quit stoffel (Remote host closed the connection) |
| 12:08:54 | JdGordon | broadcast* |
| 12:08:54 | Torne | Llorean: yes, you could persist the whole cache, it's one of the optoins we discussed before |
| 12:08:54 | Llorean | Torne: Was it objected to? |
| 12:08:54 | Llorean | It seems like a really obvious solution for the short term |
| 12:08:54 | Torne | there's a few minor issues (the cache has a couple of pointers in it at the beginning that would need fixing up) |
| 12:08:54 | JdGordon | you could NOT save it to nvram |
| 12:08:54 | Torne | and you'd need to know whether the font had changed and so on |

| 13:58:20 | pondlife | Will do, but which .c file is it in? |
| 13:58:43 | JdGordon | skin_buffer.c |
| 13:58:54 | JdGordon | make sure your skins have %Xd then or are all using the same bmp |
| 13:59:06 | JdGordon | which target you on now? or you got the h300 fixed? |
| 13:59:28 | pondlife | Only got the h300, still in surgery... |
| 13:59:41 | pondlife | So, I run a sim! |
| 13:59:47 | amiconn | jhMikeS: Iirc sound_val2phys() is meant to be phased out. |
| 14:00 |
| 14:00:13 | pondlife | Ow, +98848 for Onda fans :/ |
| 14:00:22 | JdGordon | BIG screen :) |
| 14:00:49 | * | pondlife thinks a config to allow skins or not might be brewing |
| 14:00:56 | JdGordon | one of the next things on my plate is putting in an option so that buffer isnt so huge |
| 14:01:12 | pondlife | OK, sounds good |
| 14:01:58 | gevaerts | pondlife: I don't think disabling skin support is workable |
| 14:02:23 | JdGordon | we can disable loading skins |
| 14:02:28 | JdGordon | but not outright disabling it |
| 14:02:28 | pondlife | Anything happen to the idea of pre-parsing a theme/fonts to size buffers? (With, natch a reboot needed to free RAM) |
| 14:03:50 | JdGordon | kugel put it in the too hard basket |
| 14:08:57 | amiconn | n1s: The head byte handling can be improved so that the unconditional branches can go away |
| 14:09:53 | mc2739 | JdGordon: is there a way to do station logos on the FM radio skin? |
| 14:10:28 | JdGordon | pamaury: what do you tinhk about adding a "usb screen" menu item when it is connect to the main menu? mostly for HID |
| 14:10:31 | JdGordon | mc2739: not yet |
| 14:10:43 | JdGordon | patches welcome for that though :) |
| 14:11:54 | Torne | JdGordon: I like that idea.. |
| 14:12:37 | pamaury | JdGordon: that would be a good idea indeed |
| 14:13:00 | JdGordon | should be a simple addition |
| 14:13:12 | JdGordon | then we put back the default HID mode in the setting menu |
| 14:14:19 | n1s | amiconn: ah, right |

| 14:21:10 | JdGordon | are they in flyspray? |
| 14:25:52 | amiconn | Idk... I would expect those glitches to be obvious without reporting though |
| 14:27:50 | jhMikeS | amiconn: why should it be phased out? |
| 14:28:56 | n1s | hmm, whe i start my h300 and it autoresumes and i quickly press stop, the boost counter is stuck at 1 sometimes |
| 14:30:19 | S_a_i_n_t_ | wasn't the wps text scrolling in the USB screen fixed? |

| 14:31:48 | amiconn | The sound code should pass around either centibels, or percentages for linear settings. Converting to hardware bitpatterns should be handled by the respective driver |

| 14:32:16 | JdGordon | none of the theme site people are online :( |

| 14:33:42 | S_a_i_n_t_ | can't remember the last time though, so perhaps it fixed itself magically |
| 14:36:42 | jhMikeS | amiconn: I was thinking the complete opposite, pass things around as a range from 0 to n-1, n=number of levels. this way any pattern of values can be supported and it's simpler. no sound_min needed and thus fewer fields in the sound structures. |

| 14:40:34 | amiconn | Also, using hardware values makes dependency handling (like volume prescaling for positive treble/bass gain) a nightmare compared to using centibels |

| 14:43:36 | JdGordon | amiconn: sure, but im talking swcodec only for now |
| 14:44:35 | jhMikeS | JdGordon: It steals it back just before restarting playback, I think the playlist code might grab it for a bit at that point at well |
| 14:44:49 | JdGordon | is there any way of knowing it was stolen? |
| 14:45:08 | JdGordon | I want to use it as an image buffer, nothing fancy, but I need to know if it was trashed |
| 14:45:45 | * | n1s wonders why we need *so* many filetypes |
| 14:46:20 | JdGordon | or do I just use the buffering mechanism and not worry? |
| 14:47:19 | jhMikeS | it has a trashed flag set when it's stolen |
| 14:48:07 | jhMikeS | it can be stolen with voice in tact as well, with the right parameters |
| 14:48:26 | amiconn | n1s: Your current code doesn't align properly |
| 14:48:57 | amiconn | (well, it does for 0 or 2 bytes, but not for 1 or 3 bytes) |
| 14:49:40 | JdGordon | jhMikeS: if playback is stopped, do you know if bufalloc() will work? |
| 14:50:50 | n1s | amiconn: could please elaborate? (it benched the same or slightly faster than the old code) |
| 14:51:11 | | Part LinusN |
| 14:51:31 | JdGordon | maybe I claim the codec buffer instead to keep it simpler? |
| 14:51:32 | jhMikeS | JdGordon: I believe it has to be non-talkable (trashed) to use bufalloc safely. |
| 14:51:40 | amiconn | Nvm, you're right |

| 14:54:18 | kugel | I imagine you'd just need to call it directly because it doesn't happen automatically with track buffering |
| 14:54:33 | jhMikeS | if you don't know how something works, homebrew another method? :?? |
| 14:54:44 | JdGordon | :) |
| 14:55:06 | jhMikeS | JdGordon: btw, AUDIOBUF_STATE_INITIALIZED means playback trashed your buffer (because it reinitialized) |

| 14:57:54 | kugel | coping that part and making sure find_albumart() actually finds the station logos should get you somewhere |
| 14:58:13 | JdGordon | what state is the buffer in when the radio is started? how do i know when to release those handles? |
| 14:59:00 | kugel | it's empty, I don't know which state exactly |
| 15:00 |
| 15:00:03 | * | JdGordon attempts to open a handle in the fm screen |
| 15:00:34 | kugel | not 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 |
| 15:01:06 | jhMikeS | with playback stopped, the whole engine should be idle and all threads inactive |
| 15:01:21 | kugel | AFAIK there's no way to play audio files without entering the wps at the same time |

| 15:04:14 | JdGordon | -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 |
| 15:04:39 | kugel | fix it! :) |
| 15:04:57 | kugel | pictureflow should be able to re-use volume in lists feature |
| 15:05:27 | jhMikeS | you have to go to playback control first |
| 15:05:53 | jhMikeS | oh, pictureflow can jump right back to wps from its menu too. :) |
| 15:06:19 | kugel | jhMikeS: I mean it doesn't now, but it should be able to |
| 15:06:29 | JdGordon | bufopen() does work in the radio screen... ok, now to figure out when to close it |

| 16:14:40 | gerbil | Hi 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. |
| 16:15:49 | n1s | gerbil: i looked at it breifly, but am a bit busy right now, but will try to take a closer look sometime in the future |
| 16:15:52 | gerbil | Sorry, s/kaybox/keybox/ |
| 16:16:15 | gerbil | Thanx a lot n1s! |
| 16:16:31 | n1s | one 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 |
| 16:17:02 | n1s | also, i think your splashes have too long timeouts and also different timeouts |
| 16:17:12 | gerbil | ok, I think about it how to do it best |
| 16:17:43 | gevaerts | Just deleting the file won't do much |
| 16:18:47 | gerbil | according 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. |
| 16:19:33 | gerbil | @gevaerts: you are right, I'll change it. |

| 17:55:28 | amiconn | Basically all of them (<100 bytes though), but for archos recorder it's 300 bytes |

| 20:34:10 | archivator | Naturally, the first section that errors out is .rodata, followed by .bss and a few messages about overlaps. |

| 20:36:17 | gevaerts | ? |
| 20:36:30 | | Quit stoffel (Remote host closed the connection) |
| 20:37:39 | archivator | Hm, I was left with the impression that the plugin buffer is as big as it can possibly be. |
| 20:39:39 | Torne | no. it could be almost the whole of ram, if you wanted |
| 20:39:48 | Torne | but then there'd be very little for audio buffering :) |
| 20:40:10 | Torne | Ther eare some targets where the plugin buffer is already a reasonably large proportion of ram |
| 20:40:18 | Torne | and so making it bigger on those targets would likely be unpopular |
| 20:40:45 | Torne | but it's target-specific, and the easiest way while you are still developing your plugin is to make it bigger :) |
| 20:42:54 | Torne | what target are you actually building for? |
| 20:43:19 | mt | Is is possible to link the standard math library to a codec in a sim build ? |
| 20:46:17 | gevaerts | probably |
| 20:46:52 | archivator | Torne: ipodvideo |
| 20:47:01 | archivator | 32MB version |
| 20:47:46 | Torne | well, it's 512kb already on ipodvideo, but you can just make it bigger for now |
| 20:48:04 | Torne | there's ~28MB of ram free or so, audio buffering won't mnind losing another meg :) |
| 20:48:35 | Torne | you'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*.. ;) |
| 20:49:24 | archivator | make 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) |
| 20:49:47 | Torne | i hope that's data, not code.. ;) |
| 20:50:27 | archivator | it is. and that's the smallest it gets! |
| 20:51:14 | Torne | well, data is dealable-with, generally |
| 20:51:22 | Torne | thing with giant code are more awkward |
| 20:52:10 | linuxstb | archivator: This is the "lite" version of festival? ;) |
| 20:52:56 | Torne | (frotz has 55KB of actual code, not even counting const data :) ) |
| 20:53:06 | Torne | (and i've not even ported half of it) |
| 20:53:17 | Torne | (always seems like a lot to play text adventures) |
| 20:53:31 | archivator | linuxstb: 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. |
| 20:53:33 | Torne | it's only fair that making the thing talk is bigger ;) |
| 21:00 |
| 21:00:08 | archivator | re: compression - this is my top choice at the moment - http://www.oberhumer.com/opensource/lzo/lzodoc.php |
| 21:00:57 | archivator | Simple, gpl2, claims to be really fast (haven't done any testing), in-place (!) |
| 21:01:03 | Torne | well, is compression the answer, though? How small will the data go and still be decompressable quick enough? |
| 21:01:51 | | Part watto |
| 21:02:08 | archivator | Torne: 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.. |
| 21:04:32 | linuxstb | Would it make sense to partially load it into a cache, in a similar way to font glyphs? |
| 21:04:44 | Torne | yah, i'm just saying.. it's worth at least trying to compress it to see how generally compressable it is at *all* |
| 21:04:58 | Torne | obviously the rate will vary depending on the technique/algorithm/etc |
| 21:05:21 | Torne | and yeah, what llorean said. does it all need to be in ram at once? |
| 21:06:08 | Torne | er, linuxstb |
| 21:09:59 | markun | archivator: I think espeak would have been smaller :) |
| 21:10:08 | markun | (much smaller) |
| 21:10:15 | markun | too bad of the GPL version |
| 21:11:37 | archivator | linuxstb: 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 :) |
| 21:11:56 | archivator | markun: trust me, I know. See the report on the wiki page. However, there are other problems with eSpeak. |
| 21:12:27 | markun | but I really like espeak :) |
| 21:12:38 | markun | (the horrible dutch output was done by me ;) |
| 21:13:00 | archivator | markun: really? The default English voice is horrendous imho. C++ doesn't help, either. |
| 21:13:20 | markun | well, I believe he removed the C++ stuff (at least the templates) |
| 21:13:25 | markun | uses structs now |
| 21:13:42 | pixelma | gets a lot better with mbrola |
| 21:13:56 | archivator | Define "now". 'Cause we can't use the latest versions due to GPLv3 :) |
| 21:13:58 | markun | pixelma: yes, but that doesn't run on rockbox :) |
| 21:14:14 | archivator | pixelma: and festival is wonderful with multisyn. Your point being? :P |

| 21:21:25 | archivator | Dear $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. |
| 21:22:47 | mt | Why 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 !) |
| 21:23:41 | linuxstb | mt: Compiling for a target or the sim? IIRC, SDL has a dependency on libm, so libm is linked with the sim. |
| 21:24:28 | mt | linuxstb: sim |
| 21:24:31 | linuxstb | Don't ask me why it's returning wrong results though... |
| 21:24:55 | mt | ah .. that was my next question |
| 21:26:23 | linuxstb | mt: It sounds like you should return to it tomorrow morning - I am sure it will be clearer then... |
| 21:27:20 | archivator | Hm, 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. |
| 21:27:53 | mt | must .. hear .. sound :( |
| 21:28:20 | linuxstb | mt: So this is the original floating-point code you're trying to get to work? |
| 21:28:37 | mt | Yes |
| 21:29:31 | mt | linuxstb: Everything seems to be working fine now, except for those maths functions which ruin everything |
| 21:32:46 | linuxstb | archivator: What did you mean in -community by "flite has preliminary utf8 support" ? Rockbox uses utf8... |
| 21:34:22 | archivator | linuxstb: 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) |
| 21:34:54 | archivator | Because, if it doesn't, that means the voice scripts are unlikely to support it, either, which leaves us in a very bad place. |
| 21:35:29 | linuxstb | What encodings does it support? |
| 21:37:53 | archivator | linuxstb: 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. |

| 21:49:06 | archivator | Ah, 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. |

| 23:33:32 | Strife89 | bertrik: What do you mean, "RDS support"? |
| 23:35:13 | bertrik | Strife89, 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) |
| 23:35:34 | kenguest | bertrik: do some players even support that? |
| 23:36:19 | Strife89 | bertrik: Ah; I suppose I should try and do a design that will allow for this data? |
| 23:36:24 | bertrik | kenguest, there are indeed only a few players where the fm chip supports RDS, basically just the gigabeat s |
| 23:37:00 | gevaerts | bertrik: also the apple fm remote IIUC |
| 23:37:25 | bertrik | Strife89, it's no use really to make a WPS or anything before it's supported in the rockbox core |
| 23:37:32 | bertrik | gevaerts, ah yes, true |
| 23:37:59 | kenguest | bertrik: 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. |
| 23:38:08 | Strife89 | bertrik: But it would still be handy to have base WPSs for the next release. |
| 23:38:19 | kenguest | just a thought! |
| 23:39:07 | Strife89 | bertrik: Besides, I can't really contribute anything else to the project. :( |

| 23:39:30 | bertrik | Strife89, we could have a receiving strength indicator on quite short notice |
| 23:39:44 | mt | kugel : (logs) do you know anything about libm+codecs in the sim ? any libm funciton I use in a codec just returns zero (sin, cos, pow ... ). It seems to be something with the linking ? |
| 23:40:09 | gevaerts | Strife89: most players won't have RDS, so there's no need to wait anyway :) |
| 23:40:47 | bertrik | there's a patch on FS that adds support for RSSI for most fm chips, so we basically just need some kind of tag for it and a WPS using it |

| 23:43:28 | bieber | Quick 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? |
| 23:44:07 | gevaerts | bieber: we don't have copyright assignments. The standard is useful, with your name in it |
| 23:44:13 | bieber | Okay |
| 23:44:26 | CIA-5 | New commit by alle (r25973): Avoid duplicated code, create a formatting function for FM frequency |
| 23:44:31 | bieber | Is the $Id line auto-generated, or do I need to fill that out? |
| 23:44:49 | bluebro | bieber: that is generated. It"s a keyword substitution done by svn |
| 23:44:54 | bertrik | don't fill it out |
| 23:45:11 | bluebro | bieber: see http://svnbook.red-bean.com/en/1.4/svn.advanced.props.special.keywords.html for details. |
| 23:45:36 | bluebro | basically, you can just copy it (no need to adjust a wrong filename) and set the svn:keywords property correctly. |
| 23:45:51 | bieber | Okay, so I'll just write $Id$? |
| 23:47:16 | | Quit adnyxo (Ping timeout: 248 seconds) |
| 23:47:25 | bluebro | yes, basically. I for one usually just copy an existing Rockbox file header and leave the line as-is. |
| 23:47:45 | pixelma | I never saw anything else than MHz for FM frequncies (except in preset files but that's not something that will be presented usually) |
| 23:47:55 | bluebro | if it contains wrong information it doesn't matter at all, svn will replace that upon commit. |
| 23:48:06 | pixelma | frequencies too. |
| 23:49:09 | gevaerts | Strife89: there's no technical reason to wait I think |

| 23:49:28 | bieber | Got it |
| 23:50:04 | Strife89 | Time to compile a bunch of sims, then. |
| 23:51:28 | AlexP | kenguest: The info is dynamic, pretty much (song/station info, that sort of thing). |
| 23:51:55 | AlexP | bertrik: And yes, RDS support makes lots of sense now :P (hint hint) :) |
| 23:52:53 | kenguest | AlexP: ah ok. i thought perhaps there'd be usable info there for configuring 'preset radio stations' |
| 23:52:58 | pixelma | and how would you chose the format type for frequencies? The commit message doesn't tell :\ |
| 23:53:37 | AlexP | kenguest: It is also used for things like alternative frequency lists, so it depends where you are |
| 23:53:55 | kenguest | gotcha |
| 23:54:17 | gevaerts | AlexP: there's the unique station identifier as well. That's not dynamic |
| 23:54:18 | AlexP | For 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) |
| 23:54:44 | AlexP | gevaerts: Yeah, but then you need to tie it to the frequency used for that station in a particular area |
| 23:55:16 | AlexP | For instance Radio 2 doesn't have just one frequency, it depends if you are in London/Manchester/Cleethorpes/wherever |
| 23:55:40 | gevaerts | Sure, 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 |
| 23:55:44 | AlexP | Anyway, the point I'm making is that it is probably easier to do it by hand/get it from existing lists |
| 23:55:46 | bieber | bluebro: 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? |
| 23:55:46 | bertrik | gevaerts, 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. |
| 23:56:06 | gevaerts | bertrik: not the name, the ID. That's different again :) |
| 23:56:30 | bieber | I'd be fine with writing this part in Rockox style C with static buffers and such, if it would make integration easier |
| 23:56:38 | gevaerts | The PI field |
| 23:57:00 | bluebro | bieber: integrate into the theme engine as in alternate parser for checkwps? (sorry, didn't got around reading the logs) |
| 23:57:33 | gevaerts | bluebro: JdGordon wants to replace the entire wps parser |
| 23:57:44 | bieber | The 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 |
| 23:57:54 | bertrik | Strife89, I made a list once: http://www.rockbox.org/wiki/FmTunerHardware |
| 23:57:58 | bluebro | ok. So that parser would become the Rockbox wps parser IIUC? |
| 23:58:05 | gevaerts | yes |
| 23:58:10 | gevaerts | (IIUC as well :) |
| 23:58:15 | bluebro | :) |
