Isaac, I set about adding the early xvmc additions to myth and think
I've got it taken care of, but don't have a good sample file to test
with. Know of anywhere I could get a file which would tax the CPU so I
can make some comparisons and make sure it's running correctly? Thanks,


Jason Schloer
PS, Should I move any other questions over to the dev area?

Figure around a 2Ghz p4/xp for comfortable playback (without
deinterlacing, of 
course) of 1080i at full resolution -- I was seeing around 75-85% cpu or
so 
with my 1800+ when I was playing around with some hdtv demo clips last
month 
when I did the mpeg decoding optimizations..    Found a deficiency in
the 
nvidia Xv driver, while I was at it, in that X takes _lot_ of cpu to 
downscale video from that resolution to 800x600 or 640x480.  Displaying
at 
1920x1080 was fine, though =)

If someone wanted to hook up the (very preliminary) XvMC support code
that's 
in libavcodec to mythtv, that'd help out playback time on supported
cards.  
It'd require a bit of work, though.
