#9914: ffplay fails to play RTSP TCP streams
-------------------------------------+-------------------------------------

-------------------------------------+-------------------------------------
Newer ffplay versions don't fall back to TCP when playing RTSP streams.
The last tested version which did a proper fall-back was 4.2.7-0ubuntu0.1
(e.g. from Ubuntu 20.04). See attached ffplay-ubuntu20.04-works.txt
With newer versions I was unable to play the same TCP stream anymore.
Failing versions which I've tried:
- 4.4.2-0ubuntu0.22.04.1 (e.g. from Ubuntu 22.04), see attached ffplay-
ubuntu22.04-worksnot.txt
- self-compiled snapshot from Sept 9th (e.g. N-108064-gdb85e01fd7 compiled
on Ubuntu 22.04), see attached ffplay5-not-working-snapshot20220908.txt
Reproducing might be hard without having a RTSP camera with TCP stream
available. I'm happy to provide all possible details.
The IP address:port in the Log is 127.0.0.1:1554 because there is a local
SSH tunnel to the destination network. But this hasn't been a problem for
the older version of ffplay and works well on my Ubuntu System with VLC.
Adding the parameter "-rtsp_transport tcp" makes the stream playable
immediately (tested with above 4.4.2 version).
