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].
