UDP Input from OBS doesn't work

[corent1csn]

Hello, for my end-of-study project as an audiovisual engineer I have to create a broadcast channel. In order to stream to our website I want to use the Restreamer tool to create an HLS stream from a local UDP stream. This stream must be multicast because also decoded by a DVB multiplexer, it is generated via a custom FFMPEG output in OBS with the following parameters:

But when I enter the multicast address in Restreamer nothing happens. Do you have a lead?

Thanks in advance

For multicast better use udp:// directly. I tried it with OBS locally and the latest Restreamer on a Raspberry Pi in the same local network.

When starting the Restreamer docker container, you have to add the option --net host to the docker run command, additionally to the other options. This allows the docker container to acctually access the multicast addresses.

For OBS I used these settings:

For the multicast, I used a 224. address (instead of a 239. address). Use that same address in Restreamer. In the OBS main view, press on Start Recording in order to start sending the stream to the multicast address.
