Along with Indeo4 it's the only thing missing from Intel codecs [18:16:48] <BBB> kshishkov: what type of audio is it? [18:16:51] <BBB> I'm certainly interested [18:17:00] <BBB> do you have a binary with debug symbols that runs?

[19:42:24] <Yuvi> DonDiego: then another problem is that we only have a mmx2 loop filter, wheras libtheora has an mmx one [19:42:34] <DonDiego> oh, ok :( [19:43:18] <DonDiego> Yuvi: sorry if i keep asking you what feels like every half hour, but what's the status of your theora and ogg work now?

[19:53:23] <DonDiego> :) [19:53:25] <peloverde> Dark_Shikari, then we need more input buffer padding [19:53:31] <Dark_Shikari> you can sell Quicktime DOSs for $5k+ on _legitimate_ channels [19:53:49] <peloverde> DonDiego, we need a second legal opinion about variable names [19:53:50] <DonDiego> Dark_Shikari: ? [19:54:02] <Dark_Shikari> DonDiego: hence DOSs are important enough that people pay for said exploits... [19:54:08] <Dark_Shikari> any exploit someone would pay for is something we should fix [19:54:29] <peloverde> Dark_Shikari, if we want to stop illegal reads then we should look at the google patches or be willing to up input buffer padding size [19:54:44] <Dark_Shikari> peloverde: Or we could simply do what x264 does [19:54:47] <peloverde> Dark_Shikari, why not just sell the exploits ourselves [19:54:54] <Dark_Shikari> peloverde: because it's in our interest to fix them [19:54:54] <peloverde> :) [19:55:15] <peloverde> anyway what does x264 do? [19:55:45] <Dark_Shikari> at each macroblock, it checks to see that the amount of buffer left is greater than or equal to the estimated maximum size of an MB (worst-case) [19:55:49] <Dark_Shikari> this avoids massive buffer padding [19:55:54] <Dark_Shikari> This can be applied to any set of syntax elements [19:56:00] <peloverde> I did that for AAC [19:56:03] <Dark_Shikari> calculate the maximum size, round up a lot, check buffer against that _before_ decoding that set [19:56:06] <Dark_Shikari> thus you don't have to check on every read [19:56:07] <peloverde> but I still need more padding [19:56:18] <peloverde> I need 36 bytes per frame [19:56:24] <Dark_Shikari> that's "more"? [19:56:28] <peloverde> yes [19:56:29] <Dark_Shikari> I would have assumed we already had a megabyte or two [19:56:48] <peloverde> FF_INPUT_BUFFER_PADDING_SIZE 8 [19:56:55] <Dark_Shikari> LOL [19:57:03] <Dark_Shikari> this some kind of joke? [19:57:12] <peloverde> and some of that is for get_bits [19:57:22] <merbanan> how about we add a CONFIG_SMALL define ? [19:57:22] <peloverde> so I really need to increase it to 44 [19:57:43] <Dark_Shikari> 44? more like 44,000 [19:57:46] <mru> the existing padding is only to allow get_bits loading chunks of 8 bytes [19:57:54] <BBB> Vitor1001: ok, all math is done now, I'll work on code comments and then hopefully post & commit [19:57:57] <Dark_Shikari> yeah, it doesn't stop overreads [19:58:02] <BBB> (plus all variables need useful names) [19:58:03] <Dark_Shikari> mru: we could add a branch to get_bits ;) [19:58:07] <peloverde> It stops small overeads [19:58:23] <peloverde> I do one bit overeads for w6132 and that seems to work fine [19:58:42] <Dark_Shikari> that's not tolerable [19:58:46] <Dark_Shikari> anything that makes valgrind complain is bad [19:58:49] <Dark_Shikari> _anything_ [19:59:00] <mru> reading into the padding is of course ok [19:59:00] <peloverde> Dark_Shikari, valgrind doesn't complain about the 1 bit overeads [19:59:01] <merbanan> even bugs in valgrind ? [19:59:06] <Dark_Shikari> merbanan: ok, true [19:59:09] <Dark_Shikari> but those are not that common. [19:59:12] <Dark_Shikari> mru: obviously. [19:59:12] <mru> bugs in valgrind are bad too [19:59:29] <Dark_Shikari> the only valgrind bugs I know of that affect this sort of thing are the simd data tracking bugs [19:59:32] <Dark_Shikari> in pmaddwd, etc [19:59:34] <Dark_Shikari> er, pmaddusbw [19:59:41] <Dark_Shikari> but they're trivial to shut up [19:59:49] <Dark_Shikari> you just zero on malloc [19:59:51] <peloverde> anyway until someone is willing to increase FF_INPUT_BUFFER_PADDING_SIZE to something real, trying to stop overeads is insane [20:00:32] <Dark_Shikari> then we do it [20:02:33] <Yuvi> is it worth worrying about CPUs without mmx2 or 3dnow? [20:02:55] <DonDiego> without any or both of them? [20:02:56] <mru> I think we can increase the padding to, say, 64 without much debate [20:03:02] <Yuvi> both [20:03:04] <peloverde> Yuvi, I wouldn't bother but i'm sure there are people who care [20:03:41] <DonDiego> i fear i'm about the only person with such a vintage machine, but i do care :) [20:03:57] <Yuvi> well, it's easy enough to fix for you :) [20:04:36] <Dark_Shikari> Yuvi: I say no [20:04:46] <Dark_Shikari> then again I believe we shouldn't care about cpus without sse [20:05:51] <DonDiego> Yuvi: would it be worthwhile to port the libtheora loopfilter? [20:06:55] <Yuvi> maybe, I can post a patch and see what michael says [20:07:00] <Dark_Shikari> isn't our current version pretty good? [20:07:12] <Yuvi> yeah, but requires pavgb [20:07:56] <Yuvi> (the optimal mmx loop filter would unpack to 16-bits instead, so it's mostly different code) [20:08:06] <Dark_Shikari> are you sure it would? [20:08:37] <Yuvi> it should be faster than emulating pavgb in addition to the munging pavgb needs [20:08:46] <Dark_Shikari> nope, doesn't seem so [20:09:16] <Dark_Shikari> at least maybe not [20:09:39] <Yuvi> well, if it's questionable, it's easier to emulate pavgb unless someone with such a cpu cares enough to benchmark [20:09:39] <Dark_Shikari> pavgb in coreavc is pxor/por/pand pb_254/psrlq 1/psubb [20:09:41] <Yuvi> so I'll do that [20:09:51] <Dark_Shikari> I trust the original coreavc author on this [20:09:55] <Dark_Shikari> but he might be wrong. [20:13:52] <Dark_Shikari> Yuvi: http://pastebin.org/103997 [20:15:23] <peloverde> care to use a pastebin variant that doesn't have talking ads? [20:16:13] <Dark_Shikari> what ads? [20:16:35] <mru> pastebin.ca seems clean, at least with adblock [20:16:43] <Dark_Shikari> I prefer pastebin.org's interface [20:16:46] <Dark_Shikari> and it doesn't have ads either [20:16:58] <mru> w/o adblock has the most obnoxious ads ever [20:17:03] <mru> full-screen popups [20:17:17] <Dark_Shikari> wait, people still exist that browse without adblock? [20:17:32] <mru> as surprising as it sounds, yes [20:17:53] <Yuvi> mine didn't have the offending domain blocked initially [20:17:58] <Yuvi> *.adonion.com [20:22:10] <peloverde> I find most adblockers to aggressive, so I just avoid sites that use obnoxious ads [20:22:26] <Vitor1001> BBB: are you sure that the code that does RDFT -> set real part to zero -> IRDFT is correct? [20:22:47] <BBB> Vitor1001: it gives the same output as binary [20:22:57] <BBB> Vitor1001: but I admit it looks a little odd [20:23:06] <BBB> and I have no idea what it does [20:23:10] <Vitor1001> Weird... I'll try to understand it... [20:25:26] <BBB> I'm working on simpler parts of the code ATM, the tilt correction appears similar to AMR-NB [20:25:36] <BBB> I can probably merge the two into 1 shared function [20:25:54] <Vitor1001> Nice, shared code is great, but maybe it is speed critical to AMR... [20:26:38] <BBB> to be honest, doesn't look speed-critical [20:26:41] <BBB> but I'll measure [20:26:46] <BBB> is amrnbdec slow? [20:27:16] <Vitor1001> I don't know, never benchmarked it against opencore [20:27:43] <Vitor1001> But since it is float-based, it should be faster in desktops [20:34:16] <BBB> in ~3yrs, it'll be faster&better on smartphones also [20:34:24] <BBB> moore's law probably still applies there [20:34:55] <Vitor1001> I think for smartphones its already the case [20:35:14] <BBB> we'll see [21:08:13] <CIA-92> ffmpeg: alexc * r22287 /trunk/libavcodec/aac.c: AAC: Add a new line after the TNS error message.

[21:11:32] <Dark_Shikari> it's a disaster [21:11:35] <Kovensky> so you get random hilighting inside comments [21:11:36] <Dark_Shikari> it was bought out [21:11:38] <Kovensky> Dark_Shikari: pastebin.com IS a disaster [21:11:46] <Dark_Shikari> pastebin.ca doesn't show line numbers correctly [21:11:48] <Kovensky> I'm talking in pastebin.ca's defense :P [21:11:51] <Dark_Shikari> they're covered up by the interface [21:11:56] <Kovensky> o_O [21:12:03] <mru> oh, .org is the old .com [21:12:06] <Dark_Shikari> mru: exactly.

[21:17:46] <peloverde> ^Let's see if I get flamed [21:18:03] <superdump> :) [21:18:11] <Yuvi> (isn't that an API change?) [21:18:17] <Yuvi> ABI I guess [21:18:59] <peloverde> Couldn't you have said something about that when we were discussing it five minutes ago? :) [21:20:07] <peloverde> So does that mean I need to revert? [21:20:16] <mru> no, leave it [21:20:18] <mru> we need it [21:20:21] <Yuvi> yeah [21:20:22] <mru> no point pushing it off [21:20:25] <Kovensky> bump minor? [21:20:29] <Yuvi> going to happen sooner or later [21:20:33] <Dark_Shikari> I would go for more than 64 [21:20:39] <Dark_Shikari> we need enough to cover things like "one dct block of coeffs" [21:20:41] <Dark_Shikari> in h264 [21:20:52] <Dark_Shikari> to avoid checking per-read [21:21:03] <peloverde> I went with 64 because it fixes AAC and mru suggested 64 would be ok [21:21:27] <peloverde> I didn't submit a patch because I didn't want to waste weeks bikeshedding the size [21:21:39] <peloverde> If you have a legitamte reason to increase it, increase it [21:21:49] <Dark_Shikari> k [21:22:05] <mru> if we were talking about kilobytes there could be valid objections [21:22:10] <superdump> so the revolt begins...? :) [21:22:16] <Dark_Shikari> IMO we should try to go through the codecs and certify them as "not a problem" [21:22:19] <Dark_Shikari> wrt buffer overreads [21:22:24] <peloverde> yes [21:22:27] <Dark_Shikari> and possibly raise the size. [21:22:28] <mru> ultimately we may need to have per-codec padding [21:22:35] <Dark_Shikari> mru: I agree [21:22:37] <Dark_Shikari> it should be part of the API [21:22:41] <peloverde> Indeed [21:22:42] <superdump> that would make sense i guess [21:22:43] <Dark_Shikari> that each codec has an amount of padding it asks for [21:22:49] <Dark_Shikari> a codec property [21:23:01] <Dark_Shikari> for h264, if we wanted to check per-MB, it would be a few kilobytes [21:23:05] <Yuvi> that increases the dependence of lavf on lavc though [21:23:22] <mru> lavf is already hopelessly entangled in lavc [21:23:30] * superdump sighs [21:23:44] <mru> but this change wouldn't need to make it worse [21:24:06] <mru> add a field somewhere so the calling app can request whatever padding it wants from lavf [21:25:04] <peloverde> Issue 1295 closed [21:28:56] <peloverde> superdump, do you have any thoughts on this: http://github.com/aconverse/ffmpeg-heaac/commit/4f3345b375aa5c73918330e47839... [21:30:54] <superdump> let's see... [21:33:33] <superdump> well, the logical operator doesn't display correctly in my pdf [21:33:41] <superdump> it's just a square [21:33:45] <superdump> so i can't tell [21:34:49] <superdump> i'd say unless you find any files that have numpatches 6 or you can prove that it's a bug in the spec, stick with the spec and go with 5 i guess [21:34:54] <mru> peloverde: does this look right? http://pastebin.ca/1827665 [21:35:08] <peloverde> Oh shit, it is " <=" in the .doc [21:35:12] <superdump> aha [21:35:38] <peloverde> mru, yes [21:36:19] <superdump> peloverde: is it <= 5 in the doc and < 6 in the coding tech code and > 5 in our code? :) [21:38:37] <peloverde> now I'm even more confused [21:38:57] <superdump> why? [21:39:34] <peloverde> nevermind [21:39:55] <peloverde> for a minute I thought that 6 was allowed by the spec [21:40:57] <superdump> :) [21:41:38] <peloverde> anyway the files imply CT had an encoder outputting 6 patches, which means we need to support it [21:41:40] <DonDiego> astrange: what's the status of ffmpeg-mt? [21:42:18] <peloverde> I wonder If I should forward this to dolby [21:42:31] <superdump> peloverde: hmm, might be an idea i guess [21:42:50] <peloverde> they took down the check package though [21:43:02] <peloverde> CT's website had a ton of useful stuff that dolby just killed [21:44:17] <peloverde> also can a fate test just look at sample rate and a number of channels? because I want to add tests for HE-AAC signaling [21:45:44] <mru> ffprobe tests [21:48:01] <peloverde> presumably, but that would also cover metadata [21:48:33] <CIA-92> ffmpeg: mru * r22289 /trunk/libavcodec/fft-test.c: Update include directives in fft-test.c [21:48:33] <CIA-92> ffmpeg: mru * r22290 /trunk/ (6 files in 2 dirs): Give RDFT types more meaningful names [21:48:43] <mru> we could teach ffprobe to not print metadata [21:49:09] <peloverde> maybe a flag to suppress metadata?
