  How would you override the default pixel aspect ratio if so needed?

  Perhaps there could be an aspect ratio command-line parameter similar
to the one in mplayer.
  mplayer assumes by default that pixels are square and that the input
video is non-anamorphic. However, if it so happens that the input video
is anamorphic and it does not have this info in itself (as sometimes
happens when converting between video formats) you can specify the
aspect ratio of the input with the -aspect parameter (for example,
if the input has 4:3 video but which is actually a 16:9 video squeezed
into 4:3, thus making it anamorphic, you can specify "-aspect 16:9" to
mplayer and it will unsqueeze it to that aspect ratio).
