[Mplayer-users] Patch enabling use of multiple Xvideo ports.

[Arpi]

Hi,

> nVidia drivers (1.0-1251) now provide 2 adaptors for hardware scaling and YUV conversion:
> `Video Overlay' (1 port) and `Video Blitter' (32 ports).

> MPlayer with supplied patch will select the first available Xvideo port and locks it for
> exclusive use with XvGrabPort() to avoid conflicts with other clients.
Thank you!

X11 :)

mplayer uses 50-70% cpu, but X11 also uses some CPU for blitting, maybe the
remaining 30-50%.
