如何在webrtc中的画布流上添加音频流

标签: webrtc

我想将通过getusermedia()获得的音频流添加到画布流并将其发送到远程对等体... 所以我抬起头来,并且有addTrack()。 但是addTrack()似乎无法正常工作。我正在使用chrome。

var audioTracks;
navigator.getUserMedia({ "audio": true, "video": false }, function (stream) 
{
audioTracks = stream.getAudioTracks()[0];

}, function(error) { console.log(error);});

.

.

var sharestream = canvas2.captureStream(25); // 25 FPS
peerConn.addTrack(audioTracks,sharestream);
peerConn.addStream(sharestream);

这是我的代码的一部分。怎么了? 我的webrtc完整源代码工作正常,但它不适用于addTrack()。

已于2002年10月29日更新,将getAudioTracks替换为getTracks

var canvasStream = canvas2d.captureStream(25); // parameter is optional

// get first audio track
// var audioTrack = audioStream.getAudioTracks()[0];
var audioTrack = audioStream.getTracks().filter(function(track) {
    return track.kind === 'audio'
})[0];

// append audio track into Canvas2D stream
canvasStream.addTrack( audioTrack );

// now canvas2D stream has both audio and video tracks
// peerConnection.addStream( canvasStream );
canvasStream.getTracks().forEach(function(track) {
   peerConnection.Track( track, canvasStream );
});

// create offer or answer descriptions
peerConnection.createOffer(hints).then(success).catch(failure);
