Description
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
