 Summary of the bug:
 When using -vf fps filter there is no sound in the output. I tried with
 mplayer, vlc and xine and all behave the same. No sound at all. mplayer
 even reports that there is no audio track, even though MediaInfo says
 there is

 The input in this case is 25 fps and I'm trying to convert it to 29.970

 How to reproduce:
 {{{
 % /usr/local/bin/ffmpeg -i var/VideoSamples/var/jlo.mpg -c:v mpeg2video
 -b:v 3500k -c:a ac3 -b:a 192k -vf fps=fps=29.970 -y out.mpg
 }}}
