blue screen with mplayer -vo xv  
2003-04-30 19:35

Hi,

I was experiencing an annoying conflict between the marvel drivers and the
xvideo output mode of mplayer.  This conflict causes mplayer to only show a
blue screen if it is run after xawtv is used.

I was able to track this problem down to a conflict with the chromakey of
the bes.  I also found a simple fix:

echo 'color_key_rgb 1 1 254' > /proc/mgavideo/mga0/bes

This appears to reset the chromakey to what xvideo expects.  YMMV.
