You can grab frames at whatever speed you want, but it's the camera framerate that will make a difference in the usb bandwidth and not the amount of frames you get with your application. Is the 10 fps limit achieved with compressed (MJPG) or uncompressed (YUV) frames ? Using compressed frames should allow for much higher framerates when using multiple cameras. Resolution will also have an impact on the bandwidth. Another alternative is to add another usb controler to you system, (a usb pci card if you are using a standard pc). As an example using MJPG I have no problem in using 3 cameras simultaneous (800x...@20 fps) Best Regards, Paulo _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
