[Libav-user] Create new frames from motion vectors

[Pierre Delmas]

Hello,


I currently work on a video steganography system. To do that I need to 
extract motion vectors (already done) and create new frames from those MV.


Currently I extract first the I-frames, then I calculate all P-frames 
and to finish B-frames but it doesn't work what I get is something like 
a diaporama of I-frames with no movement (or not a visible one).


Do I made something wrong ?


I can provide more details if you need.
