Indeed, it does dump exactly the same input as we dump in the UDP access.

A little difference is that the input ends in the demuxdump, while the
UDP-dump 'tee' the input
to a dump file, and keep the data flow to the next pipe line.

One of our use case is when our QA use VLC to test some setup, for example,

    file -> VLC streamer(PC)->  TS/UDP -> VLC(our device) -> TS/UDP ->
VLC(PC) playback

If they see some artifices on the VLC playback, they can do the first
triage based on the UDP-dump.
If they are identical, the issue will be forward to the video group,
otherwise networking/platform group
has to look into the packet drop issue first.
