[Libav-user] AVI and MOV playback wrong but WMV right

[Gonzalo Garramuno]

I have written an open source viewer (mrViewer under sourceforge) that 
works with frames.  All is fine except playback of AVI and MOV files.  
WMV movies play just fine.
With avis or mov formats seeking to the beginning of the movie will 
offset all frames by two frames and will not allow to display/decode the 
last two frames.
I'm wondering if someone could shed some light on why this could be so 
and things I could try.
