[FFmpeg-user] RTMP Input error (UDP output)

I am trying to use an RTMP source from the internet and broadcast it to my
local network over UDP.

In the console output below I am using avi as my file format which produces
the error. 

If I use flv, there is no error and output SEEMS to be ok but I cannot
receive the output through pwomxplayer on a Raspberry Pi.


Any help is greatly appreciated!
