The v4l2-ctl tool is used to control video4linux devices, either video, vbi, radio or swradio, both input and output.
--stream-to-host=<hostname[:port]> stream to this host. The default port is 8362. --stream-poll use non-blocking mode and select() to stream. --stream-mmap=<count> capture video using mmap() [VIDIOC_(D)QBUF] count: the number of buffers to allocate. The default is 3. ...
The v4l2-ctl tool is used to control video4linux devices, either video, vbi, radio or swradio, both input and output. It is able to control almost any aspect of such devices covering the full V4L2 API. OPTIONS -d,--device<dev>Use device<dev>as the V4L2 device. if<dev>starts with ...
Note two interfaces for Kurokesu C1 camera – this is dual stream output. One video device is for regular YUYV/MJPEG compressed output another is for h.264. You can open both of them at the same time with different programs (for example h.264 for live streaming, MJPG for onboard record...

Note the presence of audio & video control interfaces, and a number of different stream interfaces for both audio & video. If you runlsusb -d 046d:083f -v | grep -e Class -e Config, will you get anything similar? If thebNumConfigurationshas a value other than 1, t...
