Finding source frame in python deepstream

I have a project based on the multistream demo that gets rtsp input
I need to access the source frame rate (for each source)
how can I do that?
I don’t want to import a different tool just for this as the link can only be used once ( a different tool would need an extra connection)

Do you mean the rtsp stream fps in the stream header? Are you using deepstream sample app? If yes, which one? If not, what is your pipeline?
