It doesn't have to be MPEG-TS, the only thing receiving this stream
will be another FFmpeg instance, so it doesn't worry me whether it
conforms to any standards or not, all I need is something FFmpeg can
send to itself over UDP.
Since FFmpeg can read raw compressed video from a file in a number of
different codecs, I assumed it could do the same via UDP, but perhaps
not.
Thanks,
Adam.
