 Summary of the bug:
 After update and compile with the latest FFMPEG it now will decode with
 h264_mmal and encode with h264_omx.
 But after 5-6 minutes it will hang.
 Also: using v:b 1500k will produce a pixelated background.
 If v:b is higher than 3000k it will hang after 2minutes of run.
 How to reproduce:
 {{{
