I assume that the above commit is from libav?
If so yes, it is the wrong thing to do.

The code has been reworked so player
uses pix_fmt to select acceleration,
thus no special decoders are needed.
It's like other hwaccel formats.

If you want I can send a patch that removes the disabled
XvMC functionality and leaves the enabled one.
If you do it instead, be careful, there are both #ifdef and #ifdef !not's,
afair.

MPlayer has been changed to use the new API years ago,
so it should work (with recompilation, but that's given at API bump).

I cannot test it ATM, because of HW issues.
I'll try to do this shortly.

Best Regards.
