v4l2 output encoder does not support h264 (only raw)

Using tools such as v4l2loopback it's useful to create a virtual v4l2 device and write h264 video to it. Unfortunately this isn't supported by ffmpeg, this gives an error:
ffmpeg -i X -c:v h264 -f v4l2 /dev/video0
Note this is possible with other software like v4l2compress_h264.
