I was perfectly happy doing this  with cvlc / vlc, but now they broke rtsp,
and  since  Vetinari 3.0.12.x  it no longer works. Old version is not an

This is my vlc  syntax:
cvlc rtsp:// <ip>:<port>/live   --sout

I tried this with ffmpeg  but am getting errors ( unable to find suitable
output format, plainly i don't know wtf I am doing) :
ffmpeg -i rtsp://<ip>:<port>/live  -c:v libx264 -maxrate 1000k -bufsize
2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8081/

Can i get ffmpeg  to serve an http url as in vlc?

ffmpeg -i rtsp:// /<ip>:<port>/live  -c:v libx264 -maxrate 1000k -bufsize
2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8081/
