Cannot open Stream, Webinterface available

[sekuba]

Hi! Thanks for the awesome program! I had no trouble setting everything up until i got to the streaming. I can access the web interface via both my local network and through an apache revproxy i set up on a subdomain from the outside. But i can stream from neither my local network nor the outside. I tried the vanilla streaming (without your tool) via vlc with the fritzbox-provided .m3u for magentaTV and it works fine, just sadly not through the restreaming software...

The debug log offers:

while VLC shows a neverending loading bar. I am using a ubuntu server (22) with nodejs 16 installes via the nodesource repo.

I can also speak german if that helps, didn't know whats better :D

Hey 👋🏻 That's odd indeed. The expected output when actually receiving the program should be:

# DEBUG="iptv-restream:*" npm start

> iptv-restream@1.4.7 start
> node dist/app.js

  iptv-restream:config Config loaded: HOST=127.0.0.1, PORT=3000, MCAST_IF=0.0.0.0, XSPF_PROTOCOL=, XSPF_HOST=, XSPF_PATH_PREFIX=, ALLOW_UNKNOWN=false +0ms

Are you running this with or without Docker? Can you run ffprobe "rtp://@232.0.20.234:10000?sources=87.141.215.251" on the same machine for me? This takes a few seconds (~5 sec. for me) and should show something like

[...]
Input #0, rtp, from 'rtp://@232.0.10.35:10000?sources=87.141.215.251':

  Program 28106
    Metadata:

Currently, it looks like IPTV-ReStream is not receiving any data after joining the multicast group, so I'd expect ffprobe to not receive anything as well 🤔

Feel free to reply in English or German, whatever you prefer :)

Thank you for the answer :)

After some more testing, thanks to you, i actually found the problem. (which is a weird one):

Just as you expected, ffprobe yielded nothing on the server, but returned fine on my ubuntu laptop connected to the same router (via wifi though). Out of curiosity, i checked a raspi which is connected via ethernet like the server and ffprobe timed out like on the server. So I went to the cellar and switched some cables and found out that somehow one of the switches makes rtp/multicast fail (?????).

Now, with a different switch, it works just fine. Thank you so much for helping me, although your program was not at fault at all :) Your ffprobe helped me figure everything out!

Further info only if interested: The weird switch so far is working fine for everything else except multicast/rtp? (gameservers, webservers, reverse proxy, wireguard...) It is called TL-SG116 by TP-Link. I found a Telekom hilft thread in which someone complains that this switch, although advertising IGMP-snooping, does not work for MagentaTV. That may have been my problem. The user also provided a list of reportedly Meganta-compatible hardware.

Thanks again, its super nice to get support like this, and so quickly :) And your program and you are very cool!

Great to hear that it works now! Thank you very much for your kind words! 😊 It indeed looks like that TP-Link sells these switches with IGMP Snooping support even though that (according to the Telekom hilft forum) they don't (or at least not IGMPv3 as needed for MagentaTV).
