Hi!
Unfortunatelly it doesn't matter in this case. Same happens with 318, for 
both my movies (divx avi, mpeg). When I looked at the source, it seemed to
me fbdev is doing the right think, but it gets an image from the filter that 
has padding bytes after every line, to make a line a fixed length (640 
bytes).  This is only imho, and pure speculation, I haven't fixed it of 
course ;)

best regards
Denes

$$$ Hi,

$$$ you should not scale YUV image sto odd width/height..
$$$ as U,V are for 2x2 pixel blocks
