[MPlayer-users] mplayer can't seem to play 1080P raw 422 UYVY video at 120 Hz

[eric at ev-consulting.com]

Hi,
 
Can anyone explain why mplayer would not be able to keep up with this refresh rate on this system with this system?  Notice that the elpased time is more than 36 seconds, but the total requested time is 30 seconds.  The CPU is not being taxed, neither is the disc read performance.  Note that we are aware of the ds_fill_buffer command and the 2KB buffer size that it uses (last we checked in August 2009), but we did not change that buffer size, we are simply using the binary that Ubuntu found when we asked it to download mplayer. 
 
We recognize this is an extreme performance condition, and yet ... why not?  We are really just transferring data to the graphics card, right?
 
The output of mplayer with the -v option is shown below. 
 
Regards,
Eric V.
