Laurent Pinchart 23867b2511 V4L/DVB (9661): uvcvideo: Commit streaming parameters when enabling the video stream ... Sonix-based cameras seem to require the host to commit video streaming parameters before selecting the alternate endpoint. While most applications issue a VIDIOC_S_FMT ioctl before starting streaming, this is not required by the V4L2 specification. The problem has been noticed on Ubuntu 8.10 with applications using libv4l. The library blocks VIDIOC_S_FMT calls when the requested format is identical to the currently selected format. As the driver commits video streaming parameters when initialising the device, only the first run of a libv4l-enabled application would succeed. For the sake of completeness, experiment showed that the camera keeps sending 12 bytes isochronous packets (header only, no data) without toggling the FID bit if video streaming parameters haven't been committed before selecting the alternate endpoint.
