IEGD had TFP for a long time since this is a Moblin requirement. However,
what is missing is vaPutSurface() support to an X11 Pixmap. I have not
tried yet, and I doubt it would work anyway, please try:
$ ./vaapi_h264 --getimage pixmap
It's much simpler to check that way. ;-) This is available in
If this works, a way to avoid the FBO is to use the VA/GLX 'bind' API
instead of the copy.
$ ./vaapi_h264 --glx --no-vaapi-glx-use-copy
However, note that I removed that 'bind' API in my next libVA packages.
TFP is suboptimal. It was discussed to let the driver expose the
underlying Pixmap instead, but I don't think it's available yet. And, this
is quite obsolete anyway. Proper implementation of vaCopySurfaceGLX() is

Wow, I never tried that many. Is this concurrent from within the same
process or different processes?
