Firstly, please show us your command line and the complete, uncut
console output. Both contain a lot of valuable information.

Secondly, I can guess that ffmpeg inteprets your file as a sort of
playlist, which in turn contains rtp:// URLs. Or something like that.
But that's guesswork, your command and its output will tell us more.
The whitelist error message tells you that you may need to add "rtp"
to the whitelist, in case you trust your file.

Have you tried any other players?
