Hi Conrad, My only hypothesis concerning this problem is that the linux usb stack does not like that linphone makes call to it using 2 different threads (through the uvc driver). I plan to rework the grabbing component to get only one thread talking with the driver. I experience also very strange problem with that uvc driver with pictures being splitted or very unstable and ffmpeg complaning of corrupted mjpeg bitstream. I think all this is related to the threading design used in linphone. Concerning windows vista, I know there are several problems but unfortunately I could never have a try myself. A friend of mine is going to give me its PC with vista installed to get a chance to solve all those problems.
