Mplayer libtheora support does not handle 4:4:4 or 4:2:2 theora videos correctly

Description
Theora (and libtheora) support 4:4:4 and 4:2:2 visuals in addition to the common 4:2:0. Since libtheora hands applications planar YUV data the application must read the colorspace from the decoded headers and treat the returned frames correctly.
VLC and (very current) gstreamer correctly handle these files.

Mplayer gives oddball colors.

A patch for this was posted to mplayer-users. I've tested the patch and can confirm that it works.

Patch was committed some time ago.
Note that recent versions of libtheora now support 4:4:4 and 4:2:2 pixel formats, so these files will be appearing "in the wild".
