[02:41:16] <Compn> KotH [02:41:48] <Compn> this will finally solve a ton of incoming problems, having an automated bug creation [02:43:18] * Compn sleeps before any more good ideas leak out of his brain [02:45:18] <beandog> dont you want them to leak out? [02:45:32] <beandog> aren't there ftpds with fam? [02:46:09] <Compn> fam ? [02:46:19] <beandog> file alteration monitor [02:47:06] <beandog> anyway [02:47:13] <beandog> im sure theres an ftpd that supports hooks [02:47:40] <beandog> alright, Im gonna go bump stuff now. [02:47:49] <beandog> packages, that is. [02:55:24] <Compn> the order in which to report bugs would change, first > upload file, second > reply to roundup issue. a more advanced script could even move such files into issueXXXX dirs automatically.

[17:24:11] <Dark_Shikari> (images, and macros, and viruses) [17:24:32] <mru> no, it goes much further [17:24:41] <mru> file formats are only a tiny part of midi [17:24:47] <Dark_Shikari> ok, true [17:24:55] <mru> it contains electrical specs for connecting stuff [17:25:03] <mru> and wire protocols [17:25:09] <mru> sync mechanisms [17:25:11] <mru> etc etc [17:25:25] <mru> it's mainly about _playing music_ [17:25:48] <kshishkov> on instruments with digital interfaces [17:25:52] <Dark_Shikari> mru: well it's like MPEG-4 [17:25:56] <Dark_Shikari> there's MPEG-4 part 2 and 10 (video) [17:25:59] <Dark_Shikari> then there's audio [17:26:00] <Dark_Shikari> then there's a container [17:26:01] <Dark_Shikari> etc etc [17:26:05] <Dark_Shikari> all kinds of shit in one spec [17:26:05] <mru> and bifs [17:26:22] <kshishkov> and structured whatever [17:26:27] <mru> seriously though, ask an actual musician about midi [17:26:34] <mru> I bet file formats is not the first thing he'll mention [17:27:06] <kshishkov> mru: don't people remember that sound cards had MIDI ports, for instance? [17:27:21] <mru> evidently not [17:28:11] <kshishkov> well, I cannot say that I was introduced to computers early but even I know that stuff [17:30:35] * kshishkov reflects on it and feels extremely old [17:31:05] * mru reflects in the mirror... nah, still not very old [17:32:11] * kshishkov is not eligible for ungdom biljett anymore - should be very old indeed [17:32:30] <mru> no, that means you're not a kid anymore [17:32:50] <spaam> :) [17:33:01] <spaam> and it will be more expensive.. [17:33:15] <kshishkov> javisst [17:33:21] <Dark_Shikari> I remember midi ports. I used one with a keyboard I had [17:33:42] <Dark_Shikari> fuck, I remember when I could actually play piano. [17:33:54] <mru> spaam: relatively, it's much cheaper for those of us with decent jobs [17:34:03] <mru> spaam: but I guess you wouldn't know much about that [17:34:12] <spaam> mru: not yet.. [17:34:28] <mru> I never played the piano, only with it [17:35:58] <kshishkov> spaam: move to Ukraine, railroad tickets are much cheaper there (service quality is proportional too) [17:37:16] <spaam> kshishkov: no thanks :) next time im going to move will be malmö or someplace near :) [17:37:18] <kierank> railrunner is best ticket ever on dutch trains [17:37:48] <kshishkov> spaam: I'd like to move to the north of Gotaland [17:38:06] <spaam> kshishkov: why there? :) [17:38:22] <kshishkov> spaam: too warm for me elsewhere [17:38:25] <mru> stockholm is the only place in sweden worth living [17:38:37] <mru> kshishkov: if you want cold, go to kiruna or something [17:38:47] <spaam> mru: nothing wrong with norrland :) [17:39:04] <mru> spaam: only that it's too cold, too dark, and too far away [17:39:05] <kshishkov> mru: I dreamed of doing that [17:39:08] <mru> and too boring [17:39:32] <kshishkov> mru: if it has Internet access it's not that boring [17:39:36] <spaam> mru: boing ? haha only if you make it [17:39:46] <spaam> boring [17:40:08] <mru> so what would you do? go for a ride on the snowmobile?

[19:07:02] <mchinen> for parsers is it better to assume the frame length is at it says in the header, or is it better to look over all frame data for a new header? [19:07:38] <mru> go with the header value first [19:07:51] <mru> if you don't find the next frame where it should be, start searching [19:07:54] <mchinen> i would think the first is better, but I see some code that does the second, i guess, to look for interrupted frames. But this is subject to getting unluck [19:08:05] <mchinen> ok [19:08:14] <mru> the mpegvideo parsers must scan the entire frame [19:08:15] <mchinen> thats what i'd prefer too [19:08:18] <mru> there is no size field [19:08:30] <mchinen> i'm rebuilding a flac parser that jason ruggles submitted [19:08:41] <mru> flac parsing is nasty [19:08:50] <mru> there is no size header [19:09:04] <mchinen> hm [19:10:29] <mru> there's only a 16-bit sync word [19:10:42] <mru> which frequently occurs in the payload too [19:11:23] <mru> you have to do something like scan for the syncword, then parse and validate the header following it [19:11:40] <mru> if the header seems weird, keep searching [19:11:55] <mru> there's an 8-bit crc covering the header [19:12:10] <mru> of course there's a 1 in 256 chance it will match randomly [19:12:20] <mchinen> haha [19:12:37] <mru> so when you find a sane header with correct crc, you scan for the next sync word [19:12:49] <mru> at the end of each frame is a 16-bit crc for that frame [19:12:53] <mru> so check that [19:13:01] <jai> is this for seeking in flac? [19:13:09] <mru> jai: yes [19:13:14] <jai> k [19:13:21] <mchinen> yes [19:13:35] <mru> if the header checks out and the frame crc matches, there is still a 1 in 16 million chance it's fake [19:13:38] <mchinen> okay that's pretty much what's in there already [19:14:19] <mru> if the following frame also validates, you're probably good [19:15:11] <mru> if you think 1 in 16M sounds low, consider I have ~130GB of flac files, and my collection is small [19:15:49] <mru> and because it's compressed data, any bit string is as likely as any other [19:15:53] <mru> well, in theory [19:16:22] <mchinen> yeah, the bitrate is much higher so it's more likely. People on the list didn't like the idea of just validating two frames for this reason [19:16:31] <mchinen> (from a thread in mar 09) [19:16:46] <mru> yes, even two frames might not be enough at all times [19:17:15] <mru> if only they'd put some sync emulation prevention in there... [19:17:35] <mru> this is what happens when amateurs design file formats [19:17:38] <mru> or codecs [19:17:43] <mchinen> yeah really. [19:17:46] <mru> compresses well but is a bitch to use [19:19:41] <mchinen> maybe i'll just make the number of subsequent validated frames arbitrary and this will be enough [19:31:24] <spaam> mru: so you can make a better format? ; [19:32:07] <mru> spaam: there are some mistakes I wouldn't make [19:32:17] <jai> better framing maybe [19:32:31] <mru> that would be one thing [19:32:50] <mru> or require external framing [19:32:58] <mru> but that's annoying too
