could not find codec parameters for rtsp://

Hi there, hopefully i am on the right topic. Not sure, were to post this problem.

A short description to the background: I am using KODI 17.1 (Krypton) on different computers and mobile devices: Windows 10 (Installer, not the one from the store – it’s way too buggy), Android 5/6 and on Raspberry Pi 3.

My happens just today: I am not able to watch DVB-C iptv-streams from my FRITZ!Box 6490 Cable (Retail) with the IPTV Simple Client anymore on the Raspberry Pi’s, while the systems on Windows and Android doesn’t have any problem.

If i try to start a stream, it can’t be played back. I’ve switched the logfiles to debug and will post the content here: https://paste.ubuntu.com/24560268/

Until yesterday all were fine on the Pi’s. Only difference: Upgrade firmware of FRITZ!Box 6490 Cable from FRITZ!OS 6.63 to FRITZ!OS 6.83

This is a logfile from a windows-machine, here’s the streaming absolutely no problem: https://paste.ubuntu.com/24560276/

If i playback the url (rtsp://fritz.box:554/?freq=826&bw=8&msys=dvbc&mtype=64qam&sr=6900&specinv=1&pids=0,16,17,18,20,102,1711,1712,1714) for the above example with VLC Media Player on windows, then i’ll get the following media information:

Does anyone have a clue, what’s going on? And more important: Does anyone know, how to fix this problem?
