UVC devices that comply to the new UVC H.264 spec should work out of the box (provided the Windows UVC driver is new enough), but *only* with applications that implement support for UVC H.264. Applications that use the generic DirectShow API and try to get H.264 video from the device will fail. The only application that I know to work is Skype, as they co-designed the spec. UVC devices that implement another H.264 interface will require a custom driver and/or custom applications. -- Regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
