libxine-1.2 video_out_xvmc

Hi all,

I use a GeForce nVidia Card with nouveau driver. After seeing Mplayer
work with the libXvMC_nouveau driver (mesa-9.0.1), I tried xine. Ended
up locking up my screen.  After using the foll. patch, I manage to get
a single frame display using XvMCsoftpipe, but when using XvMCnouveau,
I seem to see many continuous
video_out_xvmc: (xvmc_update_frame_format:770) xvmc_update_frame_format
messages.
Both crash, but I think there is a clue here. The softpipe being slow,
allows the frame_format to be updated; but the faster nouveau does not
- so a string of calls.
The patch gets execution past XvMCCreateSurface in xvmc_set_context;
and upto XvMCPutSurface in xvmc_display_frame (past the
XvMCSyncSurface.

Can anyone help? BTW, this patch, which basically executes
XvMCCreateSurface with the display locked, I think, is needed.

Arvind R.
