 Hi,

 Currently, v4l2 format outputs only support rawvideo. Some outputs support
 h264, like v4l2loopback(see here
 https://github.com/umlaeute/v4l2loopback/blob/master/v4l2loopback_formats.h)

 You currently get this error if you try the following command
 ffmpeg -f x11grab -r 30 -s 2560x1440 -i :0.0+1920,0 -vcodec libx264 -f
 v4l2 -y /dev/video0

 [v4l2 @ 0x94a6c0] V4L2 output device supports only a single raw video
 stream


 I would like the ability to output to v4l2 with h264/5 encoded video
 streams.

 I can test any patches.

 Thanks,
 Sarnex
