I've got a stream like this working from a raspberry pi 4 with 4 gigs of
ram. I'm using the hardware h264 encoder on the raspberry pi using the v4l2
encoder element. I'm not sure if the new driver is the default yet or if
you need to manually turn it on to make the encoder available from
Gstreamer. It also has some weird bugs like having blue and red swapped in
the recording. I fixed it with an extra capsfilter it shouldn't need. For
25 fps setting the monitor refresh rate to 25 or 50 fps might help
slightly.
