[linux-uvc-devel] Does UVC driver supports simultaneous video streaming on device node

[Satish Ramya]

Hi ,

I am new to linux UVC driver, I connected Logitech c920 pro webcam to
qualcomm dev board through USB which is running with kernel 3.4 version.

Once it is connected , /dev/video1 is created. Logitech webcam supports
three video formats YUYV, MJPEG and H264.

Is it possible to open multiple instances of /dev/video1 ?

how to read two simultaneous video formats from the webcam, ie, one for
preview(YUYV) and another one for streaming MJPEG, so that i can avoid
encoding of yuyv for streaming.?



Thanks in advance.
