If texture is locked in DRI while rendering, the straghforward solution
is to allocate new texture for every frame or reuse old one from the ring.
The new texture will be free, one application thread can be dedicated to
push texture to AGP and than into the card, while another threads can decode

Currently, the performance when streaming video through glTexSubImage2D is
very low. In my test program and with mplayer, I get approximately 8 fps in

glDrawPixels is equally slow. I assume glTexS
