[Openchrome-users] SP8000E and 1080p video?

[gpeters@deepsky.com]

Folks,

How is openchrome at playing video at 1080p?  I just got XvMC working
with mplayer, and I am having difficulty playing 29.97Hz 1080p
video on it!  Top shows the CPU maxing out at 75% or so, and the video
plays at at an almost viable speed.

I'm wondering if I'm hitting a fundamental limit of the chipset I have
(which I doubt, since I'm finding resources on the net that say this
works).  I'm using mplayer, perhaps I should build Xine?  I'll try that
and report back.

I built libxvmc, libdrm et al.  The library Xorg is using for libdrm
is its own extension library, not the one from /lib.  I found that
interesting, but didn't screw around with it.  Should I?

All in all, I'm wondering if there's a part of my system I can speed
up to make this happen.

My syslog shows this interesting set of messages on X server
initialization:

agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0.

        This is probably a single thread having multiple
        DRM file descriptors open either dying or closing file descriptors
        while having the lock. I will not reclaim buffers.
        Locking context is 0x00000001

(for each of the two X server starts, one with VBEModes, then the
second one without so I can go at 1080p).

The next tidbit is: I can't play any 1920x1080 video while firefox is
running.  The failure looks like this in the X server log:

DRM memory allocation failed

I figure this is plain and normal; I am out of memory.  Firefox is a hog.
