Summary of the bug: If I want to save a h264 yuvj420p video stream from
webcam into a file without recoding it gives me empty file. But if I set
recoding option it works.
How to reproduce: Get Logitech C920 webcam and run the command line below:
{{{
% ffmpeg -vcodec h264 -f v4l2 -i /dev/video0 -vcodec copy -y out.mkv
ffmpeg version: git master from 2013-08-16
built on Ubuntu 12.10 x64
}}}
But if I remove '-vcodec copy' option and ffmpeg start recode from h264 to
mpeg4 everything works fine
