Qualité du média après traitement

This is were the output stopped, instead of reading the video frame by frame, it stops here and runs indefinitely. I tried to use VLC and python script to read the rtsp url, but that didn't work.
I tried the alternative using GStreamer, but i couldn't install rtsp-server on Windows 11.


Thank you for your time, any suggestion or answers are appreciated. The end goal is to convert a video to a rtsp url.
