Did you experiment with width=320:height=240 because everything works below the 640x480 resolution also the fps=30 or fps=5 options, everything stops working at correctly after the 640x480 the software scaling is just a trick like a zoom its not the real resolution :-) Best regards, Jelle _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
