Fix "Could not find v4l2 muxer"

Browse source 
The AVOutputFormat name is a comma-separated list. In theory, possible
names for V4L2 are:

    - "video4linux2,v4l2"
    - "v4l2,video4linux2"
    - "v4l2"
    - "video4linux2"

To find the muxer in all cases, we must request exactly one muxer name
at a time.
