Xvideo is better than running RGB through the X server, for sure, but 
better still is to send the uncompressed stream all the way to the Sun 
Ray. We already have H264 and MPEG-2 decoders in the firmware using a 
new X extension (Xvenc) that facilitates that. In addition, there's a 
JPEG decoder that we use for the Flash acceleration in SRSS 4.2, but 
it's only available from Windows, and only using IE. Our primary focus 
is on providing better video from remote Windows, since that's really 
what most of our customers use. I don't know what the status of plugins 
for mplayer using these features is.

That's a matter of tying the video players into our new protocol 
enhancements to use the existing Sun Ray capabilities. Performance of 
those will be improved, as we acquire the ability to use the hardware 
decoding capabilities of the Sun Ray's graphics chip. The difficulty 
over the years has been getting the graphics chip vendors to give us 
enough information (or the required driver code) to make use of the 
advanced features of the graphics chip. We now have a vendor who's 
willing to work with us so that we can now do that.
