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? mplayer->libvaapi.so->glamo_vaapi.so->libdrm.so-----kernel----->drm.ko&glamo.ko 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?
