Well, one thing I was asking for/poking at was extending the XvMC API to support standard Xv surfaces, since the XvMC API separates rendering and display. That is, we could copy data to off-screen memory, and then tell XvMC when to display it (either by a page flip or a vmem blit done by the card which would hopefully be fast enough to avoid tearing). Maybe you'd be interested in helping with that? Xv can export RGB surfaces too.. :) -- Billy Biggs vektor@xxxxxxxxxxxx
