XVideo question?

[Kendall Bennett]

Hi Guys,

I am working on our XVideo implementation and am wondering what the 
offscreen video memory functions are used for. More specifically what 
applications make use of these calls and what client level API is used to 
call them.

So far with my testing of MPlayer and Xine, it appears that only end up 
going into the drivers PutImage function, and don't seem to use the 
offscreen video memory functions. This means that all video frames get 
dumped to system memory first by the player, then copied from there to 
video memory by the driver. This gets done for every frame. 

The offscreen functionality is clearly there to avoid this overhead, but 
I can't yet figure out which applications will make use of this (nor what 
client level API functions are used so I can code my own tested).

Any help would be greatly appreciated!

Regards,
