Really, we need good threaded double buffering, or we'll just mess up the rest of the capture process. And for webcams, you won't notice it, because the webcam is usually the limiting factor for framerate. For capture cards, this definately isn't the case. Anyway, Billy is somewhat right, webcams are a trouble issue here. We need high-end performance during capture, and a one buffer approach just wouldn't work. It's worth supporting, but only as a fallback mechanism. I can try to add support for one buffer, but only as long as the capture process itself doesn't suffer from it. Full-rate capture is our first aim, webcams only come next. Ronald -- Ronald Bultje <rbultje@xxxxxxxxxxxxxxxxxxx>
