2015-08-17 03:22:34 -0500	answered a question	uvc_get_stream_ctrl_format_size: Invalid mode I have the same problem with you; and i have checked the source code of the libuvc_camera package, I guess it is the problem of the configure of the video_mode. In the source code it didn't set the video_mode as the launch file, but set it with a fixed value: "UVC_COLOR_FORMAT_UNCOMPRESSED". But i'm not sure.
