#77: Incomplete result

 I'm trying to transcode (-> MP4) a 2h video, but I never get a full time
 result; the result duration seems to be random (command line is the same)

 The problem occurs quite often on many videos, maybe it's a command
 problem

 I tried to encode 4 times, result duration are 15min, 28min, 60min, 95min.

 Command line:

 The $$$bla$$$ part is libx264-veryfast.ffpreset (of course the stars don't
 appear in command line)
