You've probably already received suggestions for VDPAU support, but I'll suggest it again anyways. VDPAU is a technology that Adobe has not implemented into their flash products yet. If GNASH were to add support for VDPAU, then it would hold a significant performance advantage over Adobe's offering on systems that support VDPAU.

The problem is you have to do colorspace conversion to RGB24, and this is not a free operation. I did initial testing with VA API on Intel and NVIDIA platforms. It turns out the gain was not that much, if any. I will post the patches tomorrow if this interests anybody.

A better solution would be to do composition with OpenGL, but I didn't know much about Gnash internals yet to persue this route.
