I misunderstood the meaning of FF_API_XVMC, I thought it was going to
remove XvMC functionality.

I have no idea XvMC works in MPlayer now, I never used it before (I
never used hwaccel before I made the get_buffer patch).

The get_buffer changes should be transparent, since I just reused the
compatibility code from ffmpeg. At least plain sw decoders and vdpau
works the same as before after the api change.

If my card supports XvMC (sandybridge with internal GPU) I will test it.


Ciao,
