 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
