I have tried your solution and here’s what I get : Unable to find a suitable output format for 'color=s=:c=black:r='
color=s=:c=black:r=: Invalid argument
The full command was : ffmpeg -re -i test.aac color=s=$outFormat:c=black:r=$videoRate -vcodec copy -vbsf h264_mp4toannexb -acodec copy -f mpegts udp://127.0.0.1:5555 <udp://127.0.0.1:5555>
