Comment (by ubitux):

 @relaxed: both ffmpeg and avconv use faststart.

 @bat999: can you try the exact following:


 {{{
 ffmpeg -f lavfi -i sine=d=15 -y /tmp/sine.m4a
 ffmpeg -i /tmp/sine.m4a -c copy -skip_iods no /tmp/ff.m4a
 avconv -i /tmp/sine.m4a -c copy /tmp/av.m4a
 }}}

 ...and confirms that {{{ff.m4a}}} doesn't play while {{{av.m4a}}} plays?

 (Rationale: I'm just trying to generate too very close files in order to
 study the differences)
