[04:56] <Compn> hmm
[04:56] <Compn> say i have a codec with a new fourcc
[04:56] <Compn> isnt there a way to force a decoder in ffmpeg ?
[04:56] <Compn> doesnt seem to work with mkv files
[04:57] <Compn> mencoder h264.mkv -nosound -ovc copy -of lavf -endpos 5 -ffourcc BLAH -o out.mkv 
[04:57] <Compn> ffmpeg -vcodec h264 -i out.mkv
[04:57] <Compn> [matroska,webm @ 028e40c0] Could not find codec parameters for stream 0 (Video: none (BLAH / 0x48414
[05:07] <Compn> oops
[05:07] <Compn> works with ffmpeg
[05:07] <Compn> not ffplay
[05:07] <Compn> maybe i should upgrade :)

[07:41] <ron__> Hi, I'm building static FFmpeg for Linux, but FFplay won't build. Any ideas please

[13:44] <saste> michaelni, do we assume all ff* input strings are utf8 or what?
[13:45] <saste> what if for example the terminal encoding is not UTF8?
[13:46] <saste> should we validate all the input strings?
[14:40] <michaelni> saste, i dont think you can assume that. Nor could you validate it. Or you could then not even open a file that has its name in a non UTF-8 encoding

[18:20] <zWaR> hi!
[18:21] <zWaR> does ffmpeg compiled on mingw get use of proxy support included in libavformat/http.c ?
[18:28] <sulphur27> helo, where ffmpeg parse Elementary Stream Desctiptior(esds) in mpeg4  .mov file ? or just the stsd atom 
[18:34] <Compn> sulphur27 : probably ffmpeg/libavformat/mov.c
[18:35] <sulphur27> ah yes i just found it too thanks

[19:56] <ramiro> hi
[19:58] <ramiro> is it possible to force ffmpeg to pass data to my encoder in a specific pixel format? I can specify AV_CODEC_ID_RAWVIDEO, but I don't know how to specify the pixel format.
[20:01] <wm4> ramiro: no, you have to convert it yourself (using libavresample and libswscale)
[20:03] <ramiro> hm, I mixed things up. I'm writing a muxer (libavdevice output), not an encoder
[20:04] <wm4> oh
[20:08] <BBB> ramiro: -pix_fmt or -pixel_format or -vf format=...
[20:08] <BBB> ramiro: but I'm not sure whether you can force or specify a supported list in your muxer, if that's what you're looking or
[20:08] <BBB> +f
[20:09] <ramiro> yes, that's what I was looking for. doesn't seem to be possible, I guess I'll have to use the command line.
[20:10] <wm4> actually doesn't AVCodec have a pix_fmts array
[20:10] <wm4> oh that's the codec
[20:11] <durandal_1707> BBB: feel free to refactor vp9 code (i assume it would take you much less time for it)
[20:14] <BBB> hm...
[20:14] <BBB> ok
[20:14] <BBB> the idea is obviously to expose more people to the code to decrease bus factor
[20:15] <BBB> but ohwell
[20:15] <Compn> ramiro : for what device? 
[20:16] <ramiro> Compn: Blackmagic DeckLink
[20:20] <Compn> ah
[20:41] <ramiro> where are new codec IDs supposed to be added? before AV_CODEC_ID_ESCAPE130_DEPRECATED, after AV_CODEC_ID_HEVC_DEPRECATED, or somewhere else?
[20:44] <ubitux> video?
[20:45] <ubitux> i think you can defined them after the AV_CODEC_ID_HEVC (after the macro even)
[20:45] <ubitux> and don't forget a MKBETAG
[20:46] <ramiro> I haven't followed the list. what's this mess about? is ffmpeg changing from a simple counter to a tag for each codec?
[20:47] <ubitux> libav abi compat
[20:47] <ubitux> we define a tag to avoid a clash when libav adds a codec id
[21:11] <ramiro> #include "libswscale/swscale.h" doesn't seem to be needed on ffmpeg.c anymore.
[21:48] <cone-954> ffmpeg.git 03Michael Niedermayer 07master:8cdf4e08237c: ffmpeg: remove unneeded include "libswscale/swscale.h"
[21:52] <michaelni> ramiro, yes seems so, fixed
[23:49] <saste> michaelni, any comment on my av_utf8_decode patch?
[23:50] <saste> especially from security / efficiency POV?
