So don't use xv? Implement VAAPI (http://www.freedesktop.org/wiki/Software/vaapi)
which does provide an API for streaming MPEG4 streams to hardware. If you had a
DRM module for the glamo, couldn't you use it to send MPEG4 encoded video frames
to the glamo by packing them into BOs?
I guess you'd also need to modify DRI to coordinate with the x server?
I know it's not going to happen because of time constraints, but wouldn't this be
a better option than trying to bend xv into doing something it doesn't want to do?
