我已经定制了Apprtc项目。我可以从用户拨打电话,其他用户可以接听电话或拒绝电话
当我从android到web浏览器调用时,我无法在android设备中看到web浏览器的视频源但我只能在web浏览器中看到android的视频源。

通过查看你的答案SDP,它没有携带任何流/轨道 疑似问题可能是,您在浏览器中创建答案之前未添加流 您可以通过打开 chrome:// webrtc-internals /
来检查PeerConnection API调用PeerConnection API调用应该在浏览器/已解答端
中如下pc = new RTCPeerConnection({"iceServers": [{"urls": "stun:stun.l.google.com:19302"}]},
{"optional": [{"DtlsSrtpKeyAgreement": true}]
});
pc.setRemoteDescription(
new RTCSessionDescription(jsep),
function() {
console.log(' OFFER accepted ');
}, function(e) {
console.log(' OFFER Failed ', e);
});
pc.addStream(stream);
pc.createAnswer(function(answer) {
console.log('got answer', answer);
pc.setLocalDescription(answer,
function() {
console.log('set local description sucesses ');
}, function(e) {
console.log('set local description failed ', e);
});
// Send the answer to other user endpoint
}, function() {
console.log('Error: Unable to create answer');
}, {
'mandatory': {
'OfferToReceiveAudio': true,
'OfferToReceiveVideo': true,
}
});
}
因此,您的答案SDP应包含a=sendonly
行,而不是a=recvonly
。
答案 1 :(得分:1)
您的浏览器SDP具有a=recvonly
属性,这意味着本地流不会添加到您的Peerconnection中。如果您的浏览器正在向远程发送音频/视频轨道并希望接收远程流,那么它应该在AnswerSDP中有a=sendrec
。
答案 2 :(得分:0)
扩展其他答案:只有在确保已获取本地流并将其添加到RTCPeerConnection后,才应发送连接信号。
navigator.mediaDevices.getUserMedia({
audio: false, // request access to local microphone
video: true // request access to local camera
}).then(function (local_stream) {
// display preview from the local camera & microphone using local <video> MediaElement
var media_element = document.getElementById('local_video');
media_element.srcObject = local_stream;
media_element.play();
// add local camera stream to peer_connection ready to be sent to the remote peer
peer_connection.addStream(local_stream);
signal_init();
}).catch(console.log);
signal_init
是您的信令/连接回调。
