angstrom demo image and 720p playing in B7 board

Hi all,

I had an old version of beagle board, B7. Following the instructions
of http://elinux.org/BeagleBoardBeginners, I can boot it up to the
latest demo image of angstrom, http://www.angstrom-distribution.org/demo/beagleboard/.

But the memory of B7 is 128MB. It is often out of memory in gdm. So, I
remove the gdm and let it be in console mode.

The mplayer can plays 480p video with fbdev driver but not omapfb
because of lacking of X. The 720p video playing of mplayer can be made
with fbdev, too. But the output is not smooth. While the playing of
480p, the process of mplayer consume almost 99% of cpu. It is hard to
believe that it can play 720p video in mplayer smoothly.

Is there anyway to play video in 720p with B7??

BTW, the latest version of demo image is lacking of omapfbplay
command, is that normal?

USing the ARM only, you can play "some" 720p on the B7, maybe some H264
BaseProfile, but more likely only MPEG4....

the bootargs I use is:
bootargs=console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rw
rootfstype=ext3 rootwait omapfb.mode=dvi:1280x720MR-16@60
mem=99M@0x80000000

thanks for the fast replying.

I use the big buck bunny video from http://www.bigbuckbunny.org/index.php/download/.
So, I believe that is encoded with mpeg4.
