    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:// 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=;ttl=16;port=5000-5001;mode=”PLAY”
    Server: GStreamer RTSP server

    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?
