[00:32:21 CET] <Compn> feliwir : we havent seen vp6 samples in a long time
[00:32:26 CET] <Compn> where did you find them ?
[00:34:06 CET] <JEEB> games
[00:36:14 CET] <Compn> oh
[00:46:46 CET] <jamrial_> old flash also used vp6 i think
[00:47:52 CET] <JEEB> yes
[00:49:28 CET] <JEEB> the games might be using different coding modes etc from what usually is available because I have a bunch of old VP6 files and I at least didn't notice artifacts ^^; that said, those clips generally contain quite a bit of artifacts
[01:29:32 CET] <KGB> [13FFV1] 15michaelni closed pull request #105: JPEG2000-RCT exception clarification (06master...06Background) 02https://git.io/vAfsG
[02:18:08 CET] <cone-256> ffmpeg 03Nekopanda 07master:8b154cb3e90a: avcodec/mpeg2dec: Fix field selection for skipped macroblocks
[11:15:45 CET] <feliwir> Compn, i can upload the file if you wish to
[11:15:53 CET] <feliwir> Compn, i found them in an EA game
[11:16:34 CET] <feliwir> The file is definetly playing correctly with the official On2 codec set, so it must be a bug in FFMPEG
[11:16:41 CET] <feliwir> it's not some specialized game codec
[11:33:21 CET] <feliwir> is guess Aurelian Jacoubs is still the maintainer of the vp6 codec?
[12:42:55 CET] <cone-428> ffmpeg 03Michael Niedermayer 07master:0fb33a828907: avcodec/scpr: Fix reading a pixel before the first
[12:42:56 CET] <cone-428> ffmpeg 03Michael Niedermayer 07master:66acb630286c: avcodec/pafvideo: Check allocated frame size
[12:42:57 CET] <cone-428> ffmpeg 03Michael Niedermayer 07master:76cc0f0f6733: avcodec/utvideodec: Add several out of array read related checks
[12:42:58 CET] <cone-428> ffmpeg 03Michael Niedermayer 07master:570023eab3e2: avcodec/vp3: Check eob_run
[12:42:59 CET] <cone-428> ffmpeg 03Nekopanda 07master:f4d5d7e8de18: avcodec/mpeg2dec: Fix motion vector rounding for chroma components
[12:43:00 CET] <cone-428> ffmpeg 03Michael Niedermayer 07master:63a4bdbf3b73: avcodec/mpeg4videodec: Ignore multiple VOL headers
[12:51:02 CET] <JEEB> feliwir: I generally recommend checking out the history of related files if a so-called maintainer has touched it in years
[12:51:07 CET] <JEEB> he might or might have not
[14:49:07 CET] <JEEB> who here last poked around mpeg-2 video parsing?
[14:49:29 CET] <JEEB> I just got linked some improvement patches which generally look alright, but I'd like them to be looked at https://github.com/jeeb/ffmpeg/commits/mpegvideo_parser_fixes
[14:52:07 CET] <atomnuker> they make sense to me
[14:53:11 CET] <JEEB> yea, with a quick look at the spec they looked correct
[15:38:48 CET] <JEEB> atomnuker: alright, posted them on the ML
[15:53:41 CET] <JEEB> atomnuker: and then there's this "fun" :D https://github.com/jeeb/ffmpeg/commit/6117366eaadbaf48bbd88eb2a353dfc852ff3400
[16:13:42 CET] <Compn> feliwir : if you upload samples to http://streams.videolan.org/upload/ and make a bug report on http://trac.ffmpeg.org , we can do the rest :)
[16:14:07 CET] <Compn> or other filehost is ok too 
[19:22:36 CET] <atomnuker> BtbN: so both the scale and thumbnail filters require some cuda header which is only avaiblable if you're registered as an nvidia developer?
[19:23:46 CET] <BtbN> it's in the CUDA SDK
[19:24:06 CET] <BtbN> they primarily need nvcc
[19:24:11 CET] <atomnuker> seems like archlinux doesn't ship cuda.h then
[19:34:33 CET] <RiCON> atomnuker: https://www.archlinux.org/packages/community/x86_64/cuda/ ?
[19:35:04 CET] <cone-428> ffmpeg 03Michael Niedermayer 07master:f2318aee8ca8: avcodec/vp3: Error out on invalid num_coeffs in unpack_vlcs()
[19:35:22 CET] <atomnuker> BtbN: yeah, --enable-cuda_sdk fails
[20:00:39 CET] <kierank> michaelni: any suggestions instead of mb_width or mb_height
[20:04:25 CET] <cone-428> ffmpeg 03Carl Eugen Hoyos 07master:dced1f6cdfe4: lavf/rtpdec: Constify several pointers.
[20:33:42 CET] <feliwir> Compn, already contacted aurelian because i wrote with him before about vp6
[20:33:54 CET] <feliwir> but i can create a ticket aswell
[20:35:34 CET] <feliwir> uhm, i must register -.-
[20:35:51 CET] <feliwir> maybe i'll just hope aurelian will respond :D
[20:36:25 CET] <JEEB> well, if he's active about VP6 that's great
[20:40:17 CET] <feliwir> i remember him being the maintainer
[20:40:29 CET] <feliwir> (and the author of the vp6 decoder in ffmpeg)
[20:40:31 CET] <JEEB> yes, that's probably correct
[20:40:37 CET] <JEEB> I just mean that things can change :P
[20:40:56 CET] <JEEB> as in, there probably are a few things in FFmpeg that were maintained at some point, but no longer have an active maintainer
[20:42:32 CET] <feliwir> well, i see him in the mailing list
[20:42:36 CET] <feliwir> every now and then :D
[20:43:59 CET] <michaelni> kierank, no really good names, something like width_of_mb could be used

[21:34:23 CET] <durandal_1707> atomnuker: when your vulkan will errupt?
[21:44:45 CET] <Compn> feliwir : no problem . thanks
[21:57:44 CET] <durandal_1707> not
[21:58:06 CET] <kierank> durandal_1707: you become like kostya
[21:58:42 CET] <durandal_1707> kierank: how?
[21:58:43 CET] <wm4> a living markov chain?
[21:59:01 CET] <kierank> trolling
[21:59:20 CET] <durandal_1707> not
[22:00:46 CET] <durandal_1707> im waiting for vulkan erruption by atomnuker
[22:01:38 CET] <Compn> unfortunate reality
[22:02:34 CET] <Compn> we must stop holding grudges and insulting each other
[22:07:22 CET] <durandal_1707> i hate everything regarding stupid internet connection
[22:08:42 CET] <kierank> durandal_1707: move to modern country
[22:11:50 CET] <jamrial> durandal_1707: maybe it's your wifi? a crappy usb adapter can misbehave like that
[22:12:40 CET] <durandal_1707> it have too much connections
[22:12:43 CET] <durandal_1707> 7
[22:14:01 CET] <durandal_1707> the worst issue is that irc client never get aware of lost connection
[22:14:25 CET] <kierank> durandal_1707: use irccloud
[22:50:24 CET] <Chloe> irccloud is great
[23:09:20 CET] <atomnuker> durandal_1707: testing under nvidia now
[23:16:45 CET] <cone-428> ffmpeg 03Michael Niedermayer 07release/3.4:6a97ba521558: Changelog: update
[23:31:24 CET] <atomnuker> wow, it works on nvidia on my first try, doesn't crash my system too, I guess their drivers have improved
[23:32:44 CET] <atomnuker> its slower than intel for hwupload,copy,hwdownload though that's to be expected when vram != ram
[23:33:05 CET] <atomnuker> still much faster than opencl
