| 00:08:14 | Bagder | remove them |
| 00:08:20 | Bagder | cvs diff | patch -p0 -R ;-) |
| 00:08:40 | Bagder | I thought some more |
| 00:08:59 | Bagder | let's avoid the rockbox prototypes of functions the underlying OS provides |
| 00:09:10 | Bagder | like open/read etc |
| 00:09:40 | Bagder | it might not be foolproof either |

| 00:13:52 | Bagder | plugin.c misses read? |
| 00:14:42 | preglow | yo, can anyone tell me how i make rockbox makefile spam me the complete command lines as it makes? |
| 00:15:01 | Bagder | preglow: the CC lines? edit tools/make.inc |
| 00:15:01 | amiconn | Yes, exactly the same problem. Multiple "implicit declaration..." warnings, then plugin.c errors |
| 00:15:05 | preglow | Bagder: thanks |
| 00:15:40 | Bagder | amiconn: where are the multiple declarations? |
| 00:15:49 | amiconn | ??? |
| 00:16:04 | Bagder | the prob #2 before was a missing read, now you have two ;-) |
| 00:16:47 | amiconn | Not multiple declarations, but multiple warnings about implicit declaration, i.e. missing prototype |
| 00:17:01 | Bagder | ah, ok. gotcha |
| 00:17:37 | Bagder | but plugin.c includes stdio.h that should include io.h that contains the read proto... ? |

| 00:20:41 | amiconn | There is another one, mingw/io.h |
| 00:20:57 | Bagder | try including that then in stdio.h |
| 00:21:00 | amiconn | However, these definitions look a bit odd to me, e.g. |
| 00:21:13 | amiconn | _CRTIMP int __cdecl _read (int, void*, unsigned int); |
| 00:21:42 | Bagder | yes, that looks more win32 than cygwin style |
| 00:21:59 | amiconn | Including that doesn't work |
| 00:22:47 | amiconn | First it doesn't find mingw.h, then there is a flood of syntax error messages |

| 00:35:41 | HCl | anyways *stops talking* |
| 00:36:54 | amiconn | Bagder: The syntax error is most likely because of _READ_WRITE_RETURN_TYPE not being defined |
| 00:37:16 | amiconn | These are defined either in sys/config.h or cygwin/config.h |
| 00:37:46 | preglow | hcl: but yes, say you want to add two variables with an asm add for some reason, and that would be asm("add.l %1, %0" : "=d" (variablename1) : "d" (variablename2));, and the result will end up in variablename1 |

| 00:39:58 | HCl | thanks |
| 00:39:58 | preglow | HCl: simplified, but that's the gist of it, the first thing following the instruction itself is the output list, the second thing is the input list, the %0, %1 etc are aliased onto whatever gcc substitutes for them in the order they're given in the lists, in this case that'd be variablename1 and variablename2, just moved to registers, since "d" specifies a data register |

| 01:18:06 | HCl | i have actually rather high hopes of this dynarec, mainly because i can completely skip keeping account of self modifying code in range 0000-7fff |
| 01:18:20 | HCl | which means the only thing that can still go wrong with it is interrupt timing |
| 01:18:42 | preglow | HCl: i'd guess that being able to completely disregard register allocation would be pretty cool as well, 68k has way more registers than z80 |
| 01:19:40 | HCl | preglow: is there a way to tell gcc to not use certain registers? |
| 01:19:47 | HCl | how many registers does 68k have? |
| 01:19:51 | HCl | mips had 32 :P |
| 01:19:54 | preglow | HCl: sixteen |
| 01:19:59 | HCl | okay. |
| 01:20:11 | preglow | HCl: you have data registers d0-d7, address registers a0-a7, where a7 also doubles as stack pointer |
| 01:20:22 | preglow | HCl: in most instructions, you can use them interchangably |
| 01:20:38 | HCl | i guess thats usable |

| 01:22:08 | HCl | hmm. |
| 01:22:26 | amiconn | Bagder: Now I understand the issue with sleep(). The build process must not know about the system sleep(). Unfortunately it is defined in the same include we need for getting read() and friends defined... |
| 01:22:59 | Bagder | right, and then we're back to my suggestion of providing those protos ourselves! ;-) |
| 01:23:44 | amiconn | ...since we cannot include only part of a file. :( |
| 01:23:56 | Bagder | yes, and it has no fine-grained control of what parts to use |

| 01:43:46 | preglow | cache for what? |
| 01:44:37 | HCl | well. i'm having a bit of a problem, since i need to somehow link a 15bit address |
| 01:44:41 | HCl | to a memory address |
| 01:44:42 | HCl | quickly. |
| 01:44:58 | HCl | i could allocate an 15bit array of pointers, but that would consume 128kb of mem |
| 01:45:31 | HCl | on the other hand, using a cache would make it possible for blocks to get recompiled even though they didn't really need a recompile |
| 01:45:50 | HCl | and since i don't have a free() i could run out of ram while it wouldn't really be needed |
| 01:45:56 | HCl | think its worth the 128kb sacrifice? |
| 01:46:09 | HCl | prolly not as bad if i allocate it in mp3buffer ram |
| 01:46:11 | preglow | i think you should find another way |
| 01:46:18 | preglow | if there is another way |
| 01:46:30 | HCl | um, there pretty much isn't o.o.. |
| 01:46:31 | preglow | 15 bit array of pointers is pretty brute force |
| 01:46:56 | HCl | what i'd need is a hardware cache in order to be able to do it efficiently, heh |
| 01:47:04 | preglow | this is for translating z80 address space to m68k address space? |
| 01:47:07 | HCl | yea. |
| 01:47:12 | HCl | pretty much. |
| 01:47:21 | preglow | well, alot of the addresses are going to go unused |
| 01:47:22 | HCl | every address that can be jumped to in z80 |
| 01:47:37 | HCl | needs to somehow be linked to a structure with a pointer of recompiled m68k code |
| 01:47:40 | HCl | yes |
| 01:47:45 | preglow | so a lookup talbe is very wasteful |
| 01:47:49 | preglow | perhaps a hashtable? :P |
| 01:47:52 | HCl | its a mem<->speed tradeof, really. |
| 01:48:03 | HCl | well, yea, i could expand the cache. |
| 01:48:10 | HCl | using a hashtable. |
| 01:48:32 | HCl | i have no experience with building good hashes, but i can dig up my notes from my algorithms and complexity course |
| 01:48:36 | preglow | use the low 8-6 order bits of the address as an index to a table, and let each entry be a linked list |
| 01:48:41 | HCl | yea |
| 01:48:46 | preglow | will be slower, but won't waste memory, i don't know how critical it is |
| 01:48:58 | HCl | same. |
| 01:49:13 | HCl | okay,i'll do that, its prolly better, i can always trade mem for speed later |
| 01:49:56 | preglow | this is only a good idea if most of the addresses in the lookup table would be unused, and i guess that's true |
| 01:50:12 | HCl | yea. |
| 01:50:19 | preglow | having a #define for how many of the lower order bits is used as an index will let you easily trade off mem<->speed |
| 01:50:30 | HCl | good idea, i'll add that. |
| 01:51:17 | HCl | i forgot what power was in c.. was it 2**8 ? |
| 01:51:34 | preglow | pow, unless it's power of two, in which case you use << and >> |
| 01:51:45 | preglow | 2**8 is 2 << 3 |
| 01:52:08 | preglow | 2^3 = 8 |
| 01:52:50 | HCl | um. |
| 01:52:57 | amiconn | 2**8 == 2 << 8 |
| 01:53:01 | preglow | no |
| 01:53:02 | HCl | yea. |
| 01:53:10 | HCl | thats what i thought. |
| 01:53:17 | preglow | two to the eigth power is the same as 2 shifted left three times |
| 01:53:27 | preglow | no |
| 01:53:29 | preglow | that's bullshit |
| 01:53:29 | HCl | eh, no. |
| 01:53:30 | HCl | XD |
| 01:53:44 | preglow | disregard me |
| 01:54:29 | preglow | 2 << 7, btw |
| 01:54:37 | preglow | so you need to subtract one |
| 01:55:15 | HCl | i'll just use 2**8... |
| 01:55:29 | preglow | is that even an operator in c |
| 01:55:29 | preglow | `? |
| 01:55:40 | HCl | i think so o.o |
| 01:55:57 | preglow | might be, if so, i've learnt something today |
| 01:56:04 | HCl | easy to find out |
| 01:56:28 | HCl | nop |

| 01:56:43 | HCl | *wonders from what language he got ** from then* |
| 01:56:49 | HCl | i'll just use 1<<8 |
| 01:57:04 | preglow | that'll do the trick |

| 01:58:38 | HCl | i know i've done a language in which it was valid |

| 02:23:16 | HCl | filling in that function has about the same difficulty as writing an interpreter core |
| 02:23:43 | preglow | a bit more, i'd think |
| 02:23:52 | HCl | nah, its really quite simple |
| 02:23:57 | preglow | have to be careful when writing instructions |
| 02:23:57 | HCl | it does exactly the same thing as the interpreter |
| 02:24:06 | preglow | wha? |
| 02:24:10 | HCl | only it compiles instructions rather than executing them as C code |
| 02:24:14 | preglow | ahh, yes |

| 02:28:50 | preglow | basically, i'm expecting to just stare at the code 'till the flaw reveals itself |
| 02:28:53 | preglow | that's my plan |
| 02:28:59 | HCl | the most buggy part is a) getting the address to jump to right b) getting the instructions right c) getting it to return properly |

| 02:53:46 | HCl | can the m68k split registers into parts of 16 bit? |
| 02:53:54 | preglow | yes, kind of |
| 02:54:04 | HCl | how? anything like x86? |
| 02:54:07 | preglow | you have different versions of the different opcodes |
| 02:54:14 | HCl | is it possible to do say. |
| 02:54:21 | preglow | like add.l which adds dwords, and add.w, which adds words |

| 02:54:52 | HCl | its a pity ;p |
| 02:55:02 | HCl | x86 would be sweet for gameboy, since z80 splits registers too |
| 02:55:07 | HCl | but ok |
| 02:55:17 | preglow | but i'm not an 68k asm expert |
| 02:57:07 | HCl | well, inside the dynarec, i can just map the 7 gameboy registers to d0-d6.. and have sp and pc in a0-a1 |

| 03:06:42 | preglow | don't think the codec does it, at least |
| 03:07:52 | XShocK | cycle-steal will push one transfer per one request. so ech time audio interface needs additional info it wil generate that request and one more particle will be written. |

| 13:35:29 | linuxstb | If anyone wants to play vorbis files on their iRiver, we've got some work to do - I haven't found any stupid mistakes, and Tremor is still running at about 0.9% of real-time. Which probably means about 10% of real-time at 140MHz. |
| 13:36:00 | linuxstb | So far FLAC is in the lead by a long way when it comes to decoding speed. |
| 13:37:03 | CoCoLUS | the good thing is, iriver somehow made it work at proper speed, so atleast we know its -possible- ;) |
| 13:37:40 | linuxstb | But I thought they had problems with some bitrates (or am I confusing it with the Neuros?) |
| 13:38:12 | CoCoLUS | they claim everythings under 500 kbps (which is enough imho) works fine |
| 13:38:56 | linuxstb | Yep, anything higher than that, and you may as well use FLAC. |
| 13:39:36 | linuxstb | So unless iRiver have made their own decoder (i.e. not used Tremor), it should be possible. |
| 13:39:47 | CoCoLUS | i don't think they did |
| 13:39:58 | linuxstb | It seems unlikely. |
| 13:40:37 | CoCoLUS | maybe that 500 kbps limitation is because the iriver can't get enough data in time from the disk? |
| 13:40:47 | linuxstb | But anyway, the code is now all in CVS and compiling cleanly, so hopefully someone will pick up the challenge. |

| 13:44:44 | ashridah | i agree. buffering to provide smooth playback, decoding, and any added mixing features are going to be much harder |

| 16:49:33 | rasher | lennyk: you should be able to connect via usb using rockbox |

| 16:49:55 | CoCoLUS | hit your head? |
| 16:50:30 | lennyk | connecting to usb with one computer didn't work, I'll try another |
| 16:50:32 | linuxstb | It possibly due to the fact that Rockbox doesn't currently know the battery level, but I've found that I can happilly use Rockbox (including disk access), whilst the iRiver firmware won't even start. Charging always solves the problem. |
| 16:50:36 | preglow | lennyk: what's the last thing you did with it? |
| 16:51:01 | preglow | linuxstb: that might be a problem, yes |
| 16:51:02 | lennyk | listen to music via iriver firmware, turned off, went to sleep |
| 16:51:22 | lennyk | started it up this morning and you know the rest |
| 16:51:44 | preglow | lennyk: is it fully charged? |

| 16:52:21 | lennyk | probably not, i'd guess about half way, but it's plugged in |
| 16:52:42 | preglow | lennyk: then i advice booting rockbox and scandisking it a couple of times |
| 16:53:12 | lennyk | connecting via usb... |
| 16:53:22 | bobx2001 | are oyu guys going to make a boot loader |

| 16:57:50 | preglow | or a consistent solution |
| 16:58:15 | bobx2001 | you are going to make firmware for the h10 right |
| 16:58:46 | ashridah | bobx2001: not unless you're willing to spare hardware they can dismantle |
| 16:58:57 | bobx2001 | nh |
| 16:59:02 | bobx2001 | i wont even be getting a h10 |
| 16:59:09 | bobx2001 | not if it comes with iriver firmware |
| 16:59:22 | bobx2001 | i would buy one then put rockbox on it |
| 16:59:31 | ashridah | the h10's a markedly different beast iirc |
| 16:59:37 | ashridah | it's designed to be all windows happy or something iirc |
| 17:00 |
| 17:00:19 | linuxstb | I'm not sure exactly what the h10 is, but I know iRiver are moving to use more proprietory hardware - which means that a Rockbox port is not interesting for developers (no documentation for the chips). |
| 17:00:21 | bobx2001 | i just dont like the h10 |
| 17:00:34 | ashridah | then don't get one |

| 17:01:15 | preglow | the h10 core is pretty much the same as in the ipod, heh |
| 17:01:18 | bobx2001 | in fact |
| 17:01:19 | preglow | so might not be very easy |

| 17:07:44 | lennyk | more like creating... but I have heard that they might come out with a 5gb, not that I would buy one |
| 17:08:10 | bobx2001 | accord to that it would be 5 or 6 gb |
| 17:08:15 | bobx2001 | i think they will use 6 |
| 17:08:27 | bobx2001 | just to stay ahead of competition |
| 17:08:48 | lennyk | that would be interesting... officially there isn't a 6gb out in that size |
| 17:09:39 | bobx2001 | either way |
| 17:09:45 | bobx2001 | a 1gb bump would be pointless |

| 18:37:06 | HCl | hey jyp. |
| 18:37:08 | HCl | what do you think |
| 18:37:31 | HCl | should i put 2 gameboy registers in 1 m68k reg or 1 gameboy reg in 1 m68k reg? |
| 18:37:54 | jyp | 1 reg = 1 reg if possible |
| 18:38:19 | jyp | I guess m68k has more regs than z80 |
| 18:38:23 | HCl | okay |
| 18:38:24 | HCl | thanks. |
| 18:38:28 | HCl | yea. |
| 18:38:37 | HCl | though it doesn't give me much spare room |
| 18:38:57 | HCl | 7 registers -> 8 registers |
| 18:39:02 | HCl | 1 spare register |
| 18:39:04 | jyp | So, you're writing the emu at the asm level |
| 18:39:09 | HCl | dynarec. |
| 18:39:16 | HCl | rather than interpretive |
| 18:39:28 | HCl | it should be loads and loads faster. |
| 18:39:31 | CoCoLUS | hows the dynarec progressing? |
| 18:39:39 | jyp | What's dynarec ? |
| 18:39:39 | HCl | i just started on it today. do the math. |
| 18:39:41 | HCl | :P |
| 18:39:48 | HCl | dynamic recompilation |
| 18:39:51 | CoCoLUS | finished? :) |
| 18:40:09 | HCl | pretty much, you parse a z80 block |
| 18:40:20 | HCl | compile an m68k assembly block of it, till you reach a z80 jump instructio |
| 18:40:21 | HCl | n |
| 18:40:29 | CoCoLUS | to be honest, i have absolutely no clue if implementing dynarec takes a day, a week, or a year :) |
| 18:40:33 | HCl | then next time the emulator goes to that address, just call the block |
| 18:40:46 | HCl | CoCoLUS: well, so far the z80 seems incredibly simple. |
| 18:41:10 | jyp | z80 is an 8-bit machine i suppose |
| 18:41:25 | HCl | i'm mostly wondering whether having 1 spare data register is enough. |
| 18:41:37 | preglow | how do use the new decoding viewers? |
| 18:41:59 | * | HCl guesses he'll go rewrite it. |
| 18:44:00 | preglow | linuxstb: goddamn, the vorbis decoder is slow :// |

| 18:44:42 | preglow | sure |
| 18:44:49 | preglow | but it's going to be _a lot_ of work |
| 18:46:20 | CoCoLUS | if it's that much work, why did iriver include it? |
| 18:46:42 | CoCoLUS | by the time the ihp-xxx came out, ogg wasn't exactly well known |

| 19:43:42 | preglow | hahah |
| 19:43:43 | preglow | no problem |
| 19:43:54 | CoCoLUS | however that -should- be included on the iriverboot page of the wiki if you ask me |
| 19:44:07 | preglow | then feel free to add it |
| 19:44:36 | CoCoLUS | yeah like "a special warning for dumb people like myself" :) |

| 19:46:29 | CoCoLUS | with a .rockbox dir warning? |
| 19:46:49 | CoCoLUS | i thought theres just some configuration in there, and if its not there, it gets autogenerated |
| 19:49:42 | preglow | no, it contains fonts, plugins and stuff like that |
| 19:50:32 | CoCoLUS | yeah -now- i know :) |
| 19:50:33 | CoCoLUS | works |
| 20:00 |
| 20:02:29 | CoCoLUS | wtf |
| 20:02:37 | CoCoLUS | preglow? |
| 20:02:51 | CoCoLUS | your rockbox.iriver works just fine, however, mine still hangs at the result 0 |
| 20:04:32 | preglow | then i guess you've got a tool chain error |
| 20:06:04 | CoCoLUS | seems that way |
| 20:07:03 | CoCoLUS | after i worked that out i think i'll start with the very important task of porting snake2 to the larger iriver screen ;) |
| 20:09:30 | preglow | i can't get this bloody parallel load in mac.l to work :/// |
| 20:09:40 | preglow | CoCoLUS: sounds like a good idea |

| 20:13:05 | preglow | and shouldn't be allowed to code |
| 20:27:00 | preglow | linuxstb: ahoy, i've got an optimized c/asm routine for you |
| 20:31:47 | CoCoLUS | which brings us... ? :) |

| 20:32:23 | linuxstb | hehe |
| 20:32:52 | preglow | http://glow.m0f0.net/rockbox/flactest.c |
| 20:33:14 | preglow | mind you it only does up to order 8, like the arm one you sent |
| 20:33:28 | preglow | i probably should use emac in the default case for order as well |
| 20:34:06 | linuxstb | I think orders higher than 8 are quite rare - which is why the ARM version only did up to that. |
| 20:34:24 | linuxstb | I'll try and add it to libFLAC and see what happens... |
| 20:34:51 | preglow | do so |
| 20:34:59 | preglow | i don't think i cam do fir filtering any faster than that |
| 20:35:07 | preglow | only two instructions per tap, that's pretty good |
| 20:35:17 | preglow | since mac.l can do an optional parallel load as well |
| 20:35:43 | markun | linuxstb, With _LOW_ACCURACY_ I got to 3.5% real-time decoding an ogg vorbis file. |
| 20:36:27 | preglow | i can probably speed it up some more by not using the same registers all the time, i don't know enough about the coldfire to tell |
| 20:37:51 | jyp | I'd be suprised if it has more than one execution unit... |

| 20:40:27 | preglow | linuxstb: it's unnecesary now, but it's in the same url if you want it for some reason :p |
| 20:40:46 | preglow | i tried using my mac macros, but found that doing the parallel loads would be very difficul that way |
| 20:41:05 | markun | No, I forgot to listen to the result :) I will do so now. |

| 20:45:16 | CoCoLUS | why is the rockbox firmware so much faster at starting up than the original from iriver? |

| 21:03:46 | HCl | what is it? |
| 21:03:58 | preglow | linuxstb: and yeah, it MIGHT of course be faster if the whole thing is written in asm, but i doubt it |
| 21:04:03 | jyp | Let me guess, there's a nested array access in in your code ? |
| 21:04:13 | markun | linuxstb, I hear only static :( |
| 21:04:21 | HCl | *frowns* |
| 21:04:22 | HCl | um. |
| 21:04:25 | HCl | not particularly. |
| 21:04:43 | jyp | Hang on a sec |
| 21:04:46 | XShocK | by the way, what was the decision about that mpegdec Mp3+2+1 library optimized for m68k ? |
| 21:05:14 | linuxstb | I think there's a "fixed predictor" version of the same function - FLAC chooses either a fixed or linear predictor for each frame, and in my test streams about 80%-90% of the blocks seem to use linear predictors. But I'll investigate and let you know. I'll also see if it's worth doing the same for order > 8. |
| 21:05:16 | HCl | changing the optimization doesn't help... :( |
| 21:05:23 | jyp | index = offset_table[bitalloc_table[offsets[sb]].offset][index - 1]; |
| 21:05:29 | HCl | ew. |
| 21:05:31 | jyp | ... failed |
| 21:05:37 | jyp | int off = bitalloc_table[offsets[sb]].offset; |
| 21:05:38 | jyp | index = offset_table[off][index - 1]; |
| 21:05:41 | jyp | ... works |
| 21:05:58 | jyp | So, split off complex expressions is my advice |

| 21:06:12 | markun | linuxstb, yes |
| 21:06:33 | linuxstb | preglow: Yes, I'll do that. |

| 21:35:23 | preglow | linuxstb: looks like most action's happening in lpc.c |
| 21:43:21 | preglow | looks like the coldfire is very sensitive to alignment issues |
| 21:54:24 | linuxstb | preglow: any suggestions? |
| 21:55:07 | preglow | i'm looking through it now |
| 21:55:24 | preglow | we're compiling with FLAC__INTEGER_ONLY_LIBRARY, yes? |
| 21:55:48 | preglow | and btw, what efficieny is it at now? i get around 6.5% of realtime here, with the cvs version |
| 21:56:33 | linuxstb | On my test stream, I got around 7.8% before your routine, and about 8.2% afterwrds. |
| 21:57:03 | preglow | hrmf |
| 21:57:16 | preglow | are we able to profile? |
| 21:57:21 | preglow | i guess not |
| 21:58:35 | HCl | are we allowed to reverse engineer the original firmware under the reverse engineering for compatibility under the dmca? |
| 21:58:54 | linuxstb | We don't live in the USA, so why is the DMCA relevant? |
| 21:59:35 | HCl | thats a good point too. |
| 21:59:44 | HCl | i guess its relevant for developers in the usa? |
| 21:59:47 | HCl | don't we have any of those? |
| 22:00 |
| 22:00:07 | linuxstb | Or maybe if any of us wish to visit the USA in the future... |
| 22:00:25 | HCl | anyways. just saying we could always resort to reverse engineering the original firmware codecs |
| 22:00:46 | linuxstb | I did think about actually calling functions that are already in our iRivers |
| 22:01:03 | preglow | HCl: you can reverse-engineer as much as you like |
| 22:01:19 | preglow | can't think of any reason to do so myself |
| 22:01:27 | preglow | reading disassembled code is a nightmare |
| 22:02:25 | HCl | linuxstb: even better idea |
| 22:02:46 | preglow | well |
| 22:02:54 | preglow | that would make rockbox iriver firmware version dependant |
| 22:02:57 | preglow | which is one bad idea |
| 22:03:22 | HCl | you could load a file with crc/address data |
| 22:03:26 | HCl | that has each firmware |
| 22:03:30 | HCl | *shrugs* |
| 22:03:43 | linuxstb | We have only been looking at the codecs for a couple of days. I think it's a bit early to give up... |
| 22:03:49 | HCl | lol. |
| 22:03:51 | HCl | i'm not giving up |
| 22:03:52 | preglow | yes, there are ways of doing it, but it's a hack |
| 22:03:53 | HCl | i'm just saying |
| 22:04:00 | preglow | but hell |
| 22:04:00 | HCl | we could do that, if all else fails |
| 22:04:08 | preglow | profiling would be very, very useful here |
| 22:04:28 | * | HCl actually has high hopes of getting rockboy at normal speed |
| 22:04:55 | preglow | i think the progress we have made is pretty amazing |
| 22:05:02 | linuxstb | preglow: I'm not going to have much time to spend on it tonight (or tomorrow). But I'll try and commit your optimisation (in a clean way - so we can turn it on and off with a #define) tonight. |
| 22:05:30 | linuxstb | preglow: Yes, if we only wanted WAV playback, we would be finished next week. |
| 22:06:05 | preglow | linuxstb: yes, i believe there already is a MCF5249 define |
| 22:07:15 | preglow | let's hope people mostly have 16 bit flac files, there's not much to be done about the wide lpc routines |
| 22:07:34 | preglow | not in the emac apartment, at least |
| 22:08:44 | preglow | and i assume we won't ever use the FLAC__OVERFLOW_DETECT define? |
| 22:08:58 | linuxstb | One option (for FLAC) is to disable lpc completely (this is done when you encode the file) - decoding with fixed predictors is probably already fast enough for real-time at 140MHz. |
| 22:09:01 | | Nick asdasopiu is now known as thegeek (na@ti521110a080-0418.bb.online.no) |
| 22:09:06 | jyp | omg, the #gcc channel is pathetic |
| 22:09:16 | linuxstb | preglow: No, we can't afford that. |
| 22:09:19 | preglow | yees, but lpc is pretty important, i think |
| 22:09:43 | linuxstb | Again, I only tested one file, but lpc gave about a 10% smaller file. |
| 22:09:56 | linuxstb | i.e. 10MB instead of 11MB. |
| 22:09:57 | preglow | hmmm |
| 22:10:05 | preglow | will probably do nicely for us, then |
| 22:10:20 | preglow | but anyway, we need to be able to play them, that's the most important part |
| 22:11:05 | preglow | damn, how my head feels like it's stuffed with wool today |
| 22:11:22 | linuxstb | But I think we're very close to 100% anyway with FLAC. libmad and Tremor seem the real problems. |

| 23:13:13 | preglow | gr8 |
| 23:16:02 | preglow | isn't 3-4% speedup a wee bit on the imaginative side? :P |
| 23:16:50 | linuxstb | Maybe:-) |
| 23:17:05 | preglow | ahh, btw, i should have thought about that, it would have been better to put the emac macros some place else |
| 23:17:20 | preglow | since they can and probably should be used by all codecs |
| 23:17:26 | preglow | but that can wait, i guess |
| 23:18:03 | linuxstb | Yes, I thought about that - but we can always move them somewhere else. |
| 23:18:15 | preglow | yup |
| 23:18:52 | preglow | but is orders higher than eight so uncommon that you can just ignore them? |
| 23:21:03 | linuxstb | The default encoding options for FLAC specifies "-l 8" - i.e. a maximum LPC order of 8. |
| 23:21:14 | preglow | ahh |
| 23:21:26 | preglow | but i should probably add a default case in the switch some time |
| 23:22:09 | * | HCl sighs. |
| 23:22:14 | linuxstb | It's OK, if it's encoded with order > 8, the stream_decoder.c function calls a different function. |
| 23:22:20 | * | preglow pats HCl on the back |
| 23:22:27 | preglow | then hooray! |
| 23:22:31 | preglow | no bother |
| 23:22:44 | preglow | i just had a look at libmad |
| 23:22:51 | preglow | quite a lot of work to be done in layer3.c and synth.c |
| 23:23:12 | linuxstb | (don't forget layer12.c for my digital radio recordings...) |
| 23:23:29 | preglow | yes, but that doesn't use a mdct |
| 23:23:35 | preglow | so doesn't require as much |
| 23:23:41 | preglow | have you tried timing a mpeg2 file? |
| 23:23:46 | preglow | mpeg layer2 file, i mean |
| 23:24:14 | linuxstb | I'm just doing it again now, but I don't think there's much difference. |
| 23:24:23 | preglow | there really should be |
| 23:24:42 | amiconn | HCl: Wazzup? |
| 23:24:49 | preglow | if the mdct isn't a major contributor to the cpu usage, i really don't know as much as i think |

| 23:52:37 | preglow | just ask |
| 23:53:13 | pillo | thanks, i'm a newbie here (h120 owner) |
| 23:53:52 | pillo | i like very much the proportional fonts, but these don't work very well in the viewer because it's very column-dependant... |
| 23:54:33 | pillo | i have started to edit it to take into account the proportional width of the fonts, but it's going to be a huge edit |
| 23:54:53 | preglow | yes, and it needs to be done ;) |
| 23:55:05 | pillo | i thought so ^_^ |
| 23:55:22 | HCl | ick. |
| 23:55:50 | HCl | i swear. gnuboy has horrific code |
| 23:55:54 | Patr3ck | does anyone have idea why the iriver uisimulator using x11 stops directly after start with the error Floating point exception? |
