ICE candidate negotiation process

Hi,

I'm wondering, if there would be kind of a status callback, which provides me the ICE negotiation state. I'm using the Python bindings of GStreamer.

Regards

Re: ICE candidate negotiation process

'ice-connection-state' and 'ice-gathering-state' on webrtcbin. Use the
GObject notify signal to track changes.

Re: ICE candidate negotiation process

Thanks Matthew. Are you aware of any sample code, demonstrating that for GStreamer and Python?

Re: ICE candidate negotiation process

I'm not aware of anything for this specific example, no. There are
plenty of other examples regarding GObject notify signalling for other
properties though.

Re: ICE candidate negotiation process

A bit further:

        self.webrtc.connect('notify::ice-connection-state', self.on_ice_connection_state)

and later:

    def on_ice_connection_state(self, param1, param2):

        print("***ON ICE CONNECTION STATE {} {}".format(param1, type(param2)))

***ON ICE CONNECTION STATE <__gi__.GstWebRTCBin object at 0x112639a00 (GstWebRTCBin at 0x7fe915310220)> <class 'gobject.GParamSpec'>

But I can't currently figure out, what element of the "gobject.GParamSpec" contains the value. I can access "name", "nick", "blurb", "flags", but no value...

Re: ICE candidate negotiation process

Maybe like so:

 print("***ON ICE CONNECTION STATE {} {}".format(param1, param2.default_value))

But it is not helpful, since it always just returns "STATE_NEW" on different callbacks...

***ON ICE CONNECTION STATE <__gi__.GstWebRTCBin object at 0x113cf34b0 (GstWebRTCBin at 0x7fa8c52ba220)> <enum GST_WEBRTC_ICE_CONNECTION_STATE_NEW of type GstWebRTC.WebRTCICEConnectionState> ***ON ICE CONNECTION STATE <__gi__.GstWebRTCBin object at 0x113cf34b0 (GstWebRTCBin at 0x7fa8c52ba220)> <enum GST_WEBRTC_ICE_CONNECTION_STATE_NEW of type GstWebRTC.WebRTCICEConnectionState>

Re: ICE candidate negotiation process

Well, after SDP offer and answer and all ICE candidates have been sent and received I'm getting these callbacks in a row:

2020-07-10 20:39:06,132 df.py-INFO : ***ON ICE CONNECTION STATE <enum GST_WEBRTC_ICE_CONNECTION_STATE_NEW of type GstWebRTC.WebRTCICEConnectionState>

2020-07-10 20:39:06,132 df.py-INFO : ***ON ICE GATHERING STATE <enum GST_WEBRTC_ICE_GATHERING_STATE_NEW of type GstWebRTC.WebRTCICEGatheringState>

2020-07-10 20:39:06,152 df.py-INFO : ***ON ICE CONNECTION STATE <enum GST_WEBRTC_ICE_CONNECTION_STATE_NEW of type GstWebRTC.WebRTCICEConnectionState>

2020-07-10 20:39:06,197 df.py-INFO : ***ON ICE GATHERING STATE <enum GST_WEBRTC_ICE_GATHERING_STATE_NEW of type GstWebRTC.WebRTCICEGatheringState>

Is this correct?

The handler:

    def on_ice_connection_state(self, _, param2):
        self.logger.info("***ON ICE CONNECTION STATE {}".format(param2.default_value))
    
    def on_ice_gathering_state(self, _, param2):
        self.logger.info("***ON ICE GATHERING STATE {}".format(param2.default_value))

The setup:

        self.webrtc.connect('notify::ice-connection-state', self.on_ice_connection_state)
        self.webrtc.connect('notify::ice-gathering-state', self.on_ice_gathering_state)

Re: ICE candidate negotiation process

Hi,

You have to read the value from the property on the object, so something like:

def on_ice_connection_state(self, param1, param2):
print("***ON ICE CONNECTION STATE {} {}".format(param1, self.props.ice_connection_state))

Re: ICE candidate negotiation process

In reply to this post by Neil Young

OK, solved it:

        self.logger.info("***ON ICE CONNECTION STATE {}".format(self.webrtc.get_property(param2.name)))
