Nope, but you can easily pre-upload all the frames to video ram if
there's a finite number of them and then only blit, in theory this
would give up to about ~80fps at 640x480. A different thing you can do
is do the resampling on the gpu.
For both these things use the xv extension, Xglamo implements it on the gpu.
