there is working XV for the glamo. i measured 20fps on an mp4 video at 320x240
on my freerunner using XV to scale to full screen. this of course will vary
depending on audio codec (audio decoding i think ate up 20% of cpu according to
mplayer stats), bitrate, video codec and quality etc. this is via regular
run-of-the-mill XV that is supported on almost all desktops and by most video
players and using mplayer (as it gave good stats).
