Ask about rtsp/rtmp/sdp!
An ongoing project aims to open a stream in Mistserver, send the video to ffmpeg, serve it from Mistserver, receive video from python/vlc via rtsp url and apply a recognition model.
It was planned to receive it from several computers, recognize it as each model, and derive a single result.
I ran into a problem here.
There seems to be a slight frame difference even when accessing Mistserver at the same time.
Because of these frame differences, it is difficult to make the recognition result into a single image.
----question ---
I wonder if it is possible to receive and use the unique ID, number, time, etc. of the frame when receiving video through rtsp/rtmp.
I wonder if it is correct that the sdp is included inside the rtsp, and if so, is there a unique frame number inside the sdp, or is it possible to output it?
This is sdp provided by Mistserver.

It seems to have been wandering for days. Any help would be greatly appreciated!
