[mythtv-users] My Perennial Problems with XvMC

Fri Sep 15 11:15:53 UTC 2006

Hello all on this thread,

I am having similar problems to Dylan with sub-optimal XvMXC usage.  This is my
system:

OS: FC5, running vanilla 2.6.17.13
Processor: P4-2.4Ghz
Graphics Card: NVIDIA 6200, (I think, my AGP is 4x, if that will matter here)
NVIDIA Drivers: 8774 Binary Drivers.
MythTV: 0.20 
Compiled with: --enable-proc-opt --enable-xvmc --enable-dvb --enable-lirc  (I
thinks that's all the flags I used).
Monitor: Sony flat panel LCD 1280x1024, using the analogue in (no twin-view)

Following over in the thread, I can confirm:
  * XvMC is enabled in Mythtv (actually, using the standard MPEG decoder gives
fairly smooth HDTV at around 60% CPU usage)
  * [root at localhost ~]# cat /etc/X11/XvMCConfig
libXvMCNVIDIA_dynamic.so
  * [root at localhost ~]# ls -l /usr/lib/libXv*

  * Checking with xdpyinfo has XVideo-MotionCompensation
  * Checking the xorg.conf file: it uses the "nvidia" driver
  * There are no errors in the X11 log file

The mythtv frontend output is (switching to and from XvMC):

The important bits (well, I think they are,anyway):

So yep, I'm stumped too....
This also happened for Mythtv 0.19, but I thought 0.20 may have fixed it....

Cheers
Damien.
