ahh, didn't look there, thanks. But doesn't this belong to the codec? 
DV can also be in AVI and MOV, and it would be great to get the
pixel aspect for these files as well.  In mov files, there is
the pasp atom for this, but e.g. dvgrab doesn't write pasp atoms. 
IMO the only reliable way is to let the pixel aspect be set by the 
codec. Any other opinions?

I don't use libavformat for decoding.
