To elaborate:
FFmpeg found the option "flags:loop" in your command line 
with the argument "-f". After opening the muxer, it will 
send the option and the argument to the muxer.
But first, it has to decide which muxer to use, so it 
tries to auto-detect which format you want by parsing 
the output file name "mpegts" but fails.

So it appears to me the error message is correct.
