The mplayer ebuild did not enable the correct xvmc libraries for i810 and nvidia as the IUSE_VIDEO_CARDS for them are lacking. This patch will check for existence of VIDEO_CARDS and enable the correct xvmc library to be linked. However I did not figure out what to do if both i810 and nvidia are present in VIDEO_CARDS, so I left that as a comment. Reproducible: Always
