[MPlayer-users] NO-SPAM Xvmc? Nvidia or mplayer issue?

[Bill Broadley]

I'm running a mostly stock fc3 x86-64, 2.6.11.3 kernel, nvidia 7167 driver,
6600GT, amd64-3200 (s939), and 1.0pre6a.

I used ./configure ..  --with-xvmclib=XvMCNVIDIA --with-x11libdir=/usr/X11R6/lib64 --enable-xvmc.

This works:
./mplayer -vo gl foo1.2.ts
...
VIDEO:  MPEG2  1280x720  (aspect 3)  59.940 fps  14800.0 kbps (1850.0 kbyte/s)
...
vo: X11 running at 1600x1200 with depth 16 and 16 bpp (":0.0" => local display)
...

Works great, cept for dropping frames.

./mplayer -vo xv foo1.2.ts

Works great, high cpu usage, minimal if any dropped frames.

I'd like to try xvmc, so I tried:

export XVMC_DEBUG=2
mplayer -vo xvmc -vc ffmpeg12mc  foo1.2.ts

I tred the same thing with 24bpp (and restarting X) and:

vo_xvmc: looking for OSD support

Any ideas what the most critical errors imply:
X11 error: BadMatch (invalid parameter attributes)
Only buffers allocated by vo_xvmc allowed
mplayer: vd_ffmpeg.c:970: mc_get_buffer: Assertion `0' failed.

Anything else to try?  Additional info to report?  Is it likely to
be a nvidia driver issue (unlrelated to mplayer)?
