[valkjsaaa]

Describe The Bug:

FFMpeg throws an Error when using h264_omx
To Reproduce:

run the following command in shell

ffmpeg -re -f video4linux2 -video_size 1920x1080 -i /dev/video0 -c:v h264_omx -f rtsp -rtsp_transport tcp rtsp://localhost:8554/live.stream 

Expected behavior:

It should stream to the RTSP server.

Sadly, h264_omx is not supported anymore on the new Raspbian Bullseye.
See here: https://forums.raspberrypi.com/viewtopic.php?t=323351

Maybe you could try "h264_v4l2m2m" as suggested in the linked topic.

Thanks @crassmike - I removed the "omx" support from the README.
