PlayerEndpoint doesn't works with RTSP multicast uri
Manuel Hernández
Hi, I'm using the version of kurento media server 6.9.0 and I'm following the example of the Kurento-Player documentation (https://doc-kurento.readthedocs.io/en/6.9.0/tutorials/java/tutorial-player.html). Then i am trying to connect a playerEndpoint with an ip camera by rtsp multicast and the Kurento Media Player log returns this error:

If I enter the rtsp unicast of the ip camera I can see the video stream, but with the multicast tells me that invalid uri.
Why can I connect by unicast and not by multicast? From VLC I can connect with both rtsp uri: unicast and multicast..
I also put wireshark frames:

The camera starts to send data to the multicast address but kurento does not visualize the flow, it gives the error of invalid uri and executes the teardown..
