I do not think there is any "udp" output format... Try "-f mpegts";
maybe this is what you want. But I did never try... I see that "TS over
RTP" in libavformat is implemented using a TS pseudo-codec
(CODEC_ID_MPEG2TS) , and I do not know how to use it.

In fact, you are asking ffmpeg to stream over rtp the video ES contained
in your .ts file (so, you are probably streaming mpeg2 video over RTP).
Copy this in your signature, if you think it is important:
N O W A R ! ! !
