Unable to record video from different network #37

Open co2nut opened 4 years ago

co2nut commented 4 years ago

Based on examples/record-audio-video-stream, when I run it on different network, it seems that it does not go through this listener

videoSink.addEventListener('frame', ({ frame: { width, height, data }}) => {

everything works fine on same network.

I tried to add below config too, but no luck

peerConnections = new RTCPeerConnection({
            sdpSemantics: 'unified-plan',
            iceServers: [
              {
                urls : 'stun:stun.l.google.com:19302'
              },
              {
                urls : 'turn:numb.viagenie.ca',
                username: "abc@hotmail.com",
                credential: "password",
              }
            ]
          }    
})

Is there anything that I could possibly miss out?

Has anyone solved this?

Refer the document here. These examples are not currently support for srflx/relay candidate. So STUN/TURN server cannot work for these example right now.

RTCPeerConnection Negotiation

RTCPeerConnections are negotiated via REST API. The Server always offers (with host candidates) and the Client always answers. In order to negotiate a new RTCPeerConnection, the Client first POSTs to /connections. The Server responds with an RTCPeerConnection ID and SDP offer. Finally, the Client POSTs an SDP answer to the RTCPeerConnection's URL.
