Getting played time in RTSP video

[Bruno Gonzalez]

Thanks for the input.

Unfortunately, I still don't have any hints as to how to get the play time
in the original source file.

Doing back-of-the-envelope calculations on the client is not an option, I
need the actual playing time, with a precision of cents of second.

Any idea?
