> A ´software´ sync (if at all > possible) would also be hampered by IRQ latencies. It can be done in theory. Use two offscreen yuv buffers. One which gets filled by the grabber card and one which holds the currently visible video overlay. Then flip the two for each frame. Yes, IRQ latencies are a issue here. I don't think it is worth the effort. Gerd -- Gerd Knorr <kraxel@xxxxxxxxxxx> -- SuSE Labs, Außenstelle Berlin
