[02:11:31 CEST] <cone-056> ffmpeg 03Michael Niedermayer 07master:51ac3f43b8bf: avcodec/mlp_parser: Check if synccode is within buffer
[02:11:32 CEST] <cone-056> ffmpeg 03Nikolas Bowe 07master:5aeb3b008080: lavc/svq3: Fix regression decoding some files.
[16:48:17 CEST] <rhns> Hi! I'm looking for some information regarding vulnerabilities CVE-2018-1999010 to CVE-2018-1999015. 4.0.2 fixes them, 3.3.8 some of them but 3.4.4 and 3.2.12 (that hava been released at the same time) seem to still have the vulnerable code.
[16:50:13 CEST] <rhns> I have trouble figuring out if 3.4.x and 3.2.x were vulnerable in the first place. Maybe checks countering these vulnerabilities were being done elsewhere :\
[18:03:05 CEST] <durandal_1707> j-b: do you gonna sponsor addition of imm4 decoder to lavc? because I gonna write decoder.
[19:15:07 CEST] <durandal_1707> January: ping
[19:15:32 CEST] <January> durandal_1707: what's up?
[19:15:53 CEST] <durandal_1707> January: are you still working on that thing I gave you?
[19:16:37 CEST] <January> durandal_1707: not really, would you want what I did so far?
[19:17:29 CEST] <durandal_1707> January: yes, you were supposed to make use of javascript code...
[19:18:12 CEST] <January> I know what I was meant to do, I just suddenly had no time to work on it anymore
[19:18:37 CEST] <durandal_1707> it's fine
[20:07:25 CEST] <cone-788> ffmpeg 03Aman Gupta 07master:476fd6ba3a7d: avcodec/mediacodecdec: fix SEGV on modern nvidia decoders
[20:08:02 CEST] <cone-788> ffmpeg 03Aman Gupta 07release/4.0:fab3418cb9e4: avcodec/mediacodecdec: fix SEGV on modern nvidia decoders
[21:46:58 CEST] <durandal_1707> will there be special ffmpeg dev meeting at vdd?
[21:50:11 CEST] <atomnuker> just a normal one where we argue with nicholas if he's there
[21:52:40 CEST] <jamrial> lol
[21:58:11 CEST] <durandal_1707> who will talk and about what?
[21:59:18 CEST] <atomnuker> dunno, I guess we'll talk about the av1 decoder which should be at least on the ML by then
[21:59:36 CEST] <atomnuker> and a new filter api too I guess
[22:00:02 CEST] <durandal_1707> how much slow will decoder be?
[22:07:38 CEST] <TD-Linux> I would expect less than 2x as slow as the vp9 decoder
[22:17:13 CEST] <jamrial> that sounds like 4k 30fps will be impossible for anything but the latest i7/Ryzen CPUs
[22:18:20 CEST] <atomnuker> well there should still be room for optimization
[22:18:42 CEST] <atomnuker> but that does sound optimistic atm IMO
[22:19:11 CEST] <durandal_1707> ban slow video codecs
[22:20:23 CEST] <durandal_1707> encoding is even worse
[22:23:05 CEST] <atomnuker> its still not as bad as jp2k
