For >5 years ago I used to play a lot with IPTV multicast MPEG2-TS
streams (I implemented the wireshark mp2ts drop detecting, and a
out-of-tree netfilter kernel module to detect drops[1]). The web-site
is dead, but archive.org have a copy[2].

Let me quote my own Lab-setup documentation[3].

You don't need a live IPTV MPEG2TS signal, you can simply generate your
own using VLC:

 $ vlc ~/Videos/test_video.mkv -I rc --sout '#duplicate{dst=std{access=udp,mux=ts,dst=239.254.1.1:5500}}'

Viewing your own signal: You can view your own generated signal, again,
by using VLC.

 $ vlc udp/ts://@239.254.1.1:5500

I hope the vlc syntax is still valid.  And remember to join the
multicast channels, if you don't have an application requesting the
stream, as desc in [4].
