Grigori,
I just tried this out on a few interlaced videos I have, and it works
really quite well! One thing I did notice is that when playing back
content with mplayer (and -vo vdpau:deint=3) in full screen mode, the
black bars are now stale/uninitialized textures. This does not happen
if I don't use deint=3. Is it something that we're doing wrong in
nouveau, or is it an issue in st/vdpau? If it's likely an issue in
nouveau, any hints on what it might be?
