 For future tickets: Please remember that only current FFmpeg git head is
 supported here.

 If you know that your application does not support aspect ratios (which
 are defined for png) use something like `-vf scale=iw*sar:ih` to force an
 output sample aspect ratio of `1:1`. Even if FFmpeg developers would
 assume that no other software supports aspect ratios for certain output
 formats, this could not simplify the issue as FFmpeg will not change the
 aspect ratio by default.

 (Please reopen this ticket if you believe that FFmpeg interprets - and
 writes - the aspect information backwards, not sure how to rule this out.)
