Hi,

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.
Regards,
Gwenole.
