Does playing the rtsp stream with ffplay work?

> FFprobe tells me the following about my stream:  https://pastebin.com/15fkGeKG

> "ffmpeg -i rtsp://admin:XXXXXX@213.131.XX.XXX:554/Streaming/channels/101
> -codec:v libtheora -qscale:v 7 -codec:a libvorbis -qscale:a 5  1.ogg"

Please test the following (or similar) and provide both command line
and complete, uncut console output:
$ ffmpeg -i rtsp... -qscale 2 out.avi
