[MPlayer-users] Bug with x86-64

I have found some more information. When using V4L2, mplayer attempts
to set the V4L2 input format to default to BGR24 instead of YUY2.
Also, it looks like some non-initialized data is causing problems in
the ioctl to try and set the format.
I have gotten the video capture working with the following patch:

This patch also fixes a problem where the frame rate comes out as 29.0
instead of 29.97.
