Usage:

Install required packages.

sudo apt-get install gstreamer-1.0 gst-rtsp-server-1.0

Execute the script

python3 video2rtsp.py -f ./videoplayback.mp4 -p 554

Receive RTSP stream from the following endpoint

rtsp://[server's ip address]:554/stream1

I ran python3 main4.py -f /tmp/foo.mp4 -p 8554

And then if I try to view the video with

ffplay rtsp://127.0.0.1:8554/stream1

I got this error:

method DESCRIBE failed: 503 Service Unavailable
rtsp://127.0.0.1:8554/stream1: Server returned 5XX Server Error reply

I researched this error without success
