I could imagine that a problem appears when you are moving a video window from screen 1 to screen 2. For reasons as this I think they are using blitting.
Thx for answering.
When I use the "Twinview", the XV is left video blitter only. :-(
Can I set the brightness,contrast,SATURATION,hue when I use video blitter?
BTW, what is the video blitter? I can't google for information. What I get is when I play the movie first time with mplayer, it is using video overlay. Then, I play second movie, it is using video blitter..
The gxvattr comes out nothing with NV05 video blitter. So I can't set any attribute at all.
