RTSP multicast:change client_port problem

[Manel F.]

Using RTSP protocol: When we try to change the client_port in a SETUP command, the Tobii Pro Glasses 3 firmware ignore all petitions. It always chooses a random port between 5000 to 5008.

Here there is an example of a SETUP command and the Tobii glasses’ answer:

SETUP rtsp://10.4.175.180:8554/live/all/stream=0 RTSP/1.0
CSeq: 1
Transport: RTP/AVP;multicast;client_port=7000-7001

RTSP/1.0 200 OK
CSeq: 1
Transport: RTP/AVP;multicast;destination=224.3.0.0;ttl=16;port=5000-5001;mode=”PLAY”
Server: GStreamer RTSP server
Session: BL2KLjo3q+fnVkds

What we are doing wrong?

According to the gstreamer documentation, the property is called “port-range”. I haven’t tried if this works though. The gstreamer version used on the server side (in the recording unit) is 1.16.

Thanks Jonas,
unfortunately this solution doesn’t work . We are using directly the RTSP syntax. It seems that it’s a firmware bug.
How we can report a problem to Tobii developers?
