Actually I have compared my code to yours and from my tests mine is as
good or better. Actually, my basic simple code I added to vdpau nearly a
year ago works quite well too.

My patches handle all important frame handling in mplayer.c, bot inside
vdpau like your code does. I did this so it could be made to work with
other VOs. Current patches does not include needed patches to make other
VOs than vdpau work, but I have experimented with code to make xv work.

My patches only have a few requirements on the VO. Basically queue frame
for display on next vsync without blocking and supply information about
time between vsyncs and when they occur. Using opengl and X I can get
the vsync info, so I think it could be made to work fairly well with xv,
x11, opengl, and a few more as long as opengl is available.
