After establishing a connection, Live555 creates a valid MediaSource upon receiving the first legitimate SETUP request #59
Description
The mechanism by which the Live555 library creates a MediaSource upon receiving the first legitimate SETUP request is an inherent component of its own implementation logic，but there exists a counterexample where, after establishing a connection, Live555 does not create a valid MediaSource upon receiving the first legitimate SETUP request, demonstrating a deviation from the expected behavior.
Here are some test cases/seeds that violate this property, which we hope will be helpful for improving live555!
