Title:
  avconv from libav-tools.deb generate bad video in trusty/utopic but
  only "happened in i386 not amd64"

Status in libav package in Ubuntu:
  Incomplete

Bug description:
  I have a series of x86 machines for converting multimedia, but an  bug
  from avconv(from libav-tools.deb) annoyed me for a long time (and it
  even happen in 14.10) that mixing video and audio using avconv
  generated a bad media output - output video is continuity continuously
  suspended, which cannot be used (output audio is okay).

  Finnally, I find out that it only happens in 32bit 14.04 and 14.10,
  but it's hard to replace i386 to amd64.

          A command to reproduce the bug:

  	> avconv -f x11grab -i :0.0 -f alsa -i pulse -f flv -ar 22050 test.flv
  	

  	Ubuntu 12.04.5	i386:good,	amd64:good
  	Ubuntu 13.10	i386:good,	amd64:good
  	Ubuntu 14.04.1	i386:bad,	amd64:good
  	Ubuntu 14.10	i386:bad,	amd64:good
  	
  	
  	'bad' warning forever:

          Non-monotonous DTS in output stream 0:1; previous: 3947,
  current: 3891; changing to 3947. This may result in incorrect
  timestamps in the output file.

  	
  	Need help, thanks!
