오디오 스트림이 '스피커'에 추가 된 위치를 찾을 수 없습니다. 스트림을 수정하고 나중에 스트림을 추가 할 수 있습니까? 나는 libjingle 스트림을 처리하고 그것을 추가하는 느낌이 있습니다.오디오 스트림이 libjingle에 추가 된 위치는 어디입니까?
나는 내 코드의 libjingle 부분을 추가했습니다 :
import AVFoundation
import UIKit
let TAG = "ViewController"
let AUDIO_TRACK_ID = TAG + "AUDIO"
let LOCAL_MEDIA_STREAM_ID = TAG + "STREAM"
class ViewController: UIViewController, RTCSessionDescriptionDelegate, RTCPeerConnectionDelegate {
var mediaStream: RTCMediaStream!
var localAudioTrack: RTCAudioTrack!
var remoteAudioTrack: RTCAudioTrack!
var renderer: RTCEAGLVideoView!
var renderer_sub: RTCEAGLVideoView!
var roomName: String!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
initWebRTC();
sigConnect(wsUrl: "http://192.168.1.59:3000");
localAudioTrack = peerConnectionFactory.audioTrack(withID: AUDIO_TRACK_ID)
mediaStream = peerConnectionFactory.mediaStream(withLabel: LOCAL_MEDIA_STREAM_ID)
mediaStream.addAudioTrack(localAudioTrack)
}
var peerConnectionFactory: RTCPeerConnectionFactory! = nil
var peerConnection: RTCPeerConnection! = nil
var pcConstraints: RTCMediaConstraints! = nil
var audioConstraints: RTCMediaConstraints! = nil
var mediaConstraints: RTCMediaConstraints! = nil
var wsServerUrl: String! = nil
var peerStarted: Bool = false
func initWebRTC() {
RTCPeerConnectionFactory.initializeSSL()
peerConnectionFactory = RTCPeerConnectionFactory()
pcConstraints = RTCMediaConstraints()
audioConstraints = RTCMediaConstraints()
mediaConstraints = RTCMediaConstraints(
mandatoryConstraints: [
RTCPair(key: "OfferToReceiveAudio", value: "true"),
],
optionalConstraints: nil)
}
func prepareNewConnection() -> RTCPeerConnection {
var icsServers: [RTCICEServer] = []
icsServers.append(RTCICEServer(uri: NSURL(string: "stun:stun.l.google.com:19302") as URL!, username: "",
password: ""))
let rtcConfig: RTCConfiguration = RTCConfiguration()
rtcConfig.tcpCandidatePolicy = RTCTcpCandidatePolicy.disabled
rtcConfig.bundlePolicy = RTCBundlePolicy.maxBundle
rtcConfig.rtcpMuxPolicy = RTCRtcpMuxPolicy.require
peerConnection = peerConnectionFactory.peerConnection(withICEServers: icsServers, constraints: pcConstraints, delegate: self)
peerConnection.add(mediaStream);
return peerConnection;
}
func peerConnection(_ peerConnection: RTCPeerConnection!, signalingStateChanged stateChanged: RTCSignalingState) {
}
func peerConnection(_ peerConnection: RTCPeerConnection!, iceConnectionChanged newState: RTCICEConnectionState) {
}
func peerConnection(_ peerConnection: RTCPeerConnection!, iceGatheringChanged newState: RTCICEGatheringState) {
}
func peerConnection(_ peerConnection: RTCPeerConnection!, gotICECandidate candidate: RTCICECandidate!) {
if (candidate != nil) {
print("iceCandidate: " + candidate.description)
let json:[String: AnyObject] = [
"type" : "candidate" as AnyObject,
"sdpMLineIndex" : candidate.sdpMLineIndex as AnyObject,
"sdpMid" : candidate.sdpMid as AnyObject,
"candidate" : candidate.sdp as AnyObject
]
sigSend(msg: json as NSDictionary)
} else {
print("End of candidates. -------------------")
}
}
func peerConnection(_ peerConnection: RTCPeerConnection!, addedStream stream: RTCMediaStream!) {
if (peerConnection == nil) {
return
}
if (stream.audioTracks.count > 1) {
print("Weird-looking stream: " + stream.description)
return
}
}
func peerConnection(_ peerConnection: RTCPeerConnection!, removedStream stream: RTCMediaStream!) {
}
func peerConnection(_ peerConnection: RTCPeerConnection!, didOpen dataChannel: RTCDataChannel!) {
}
func peerConnection(onRenegotiationNeeded peerConnection: RTCPeerConnection!) {
}
}
나의 생각은 내가이 명령에 따라 기능의 오디오 스트림을 잡을 수 있다는 것입니다. 그 맞습니까? 또한 스트림을 수동으로 스피커에 추가 할 수 있습니까?
func peerConnection(_ peerConnection: RTCPeerConnection!, addedStream stream: RTCMediaStream!) {
if (peerConnection == nil) {
return
}
if (stream.audioTracks.count > 1) {
print("Weird-looking stream: " + stream.description)
return
}
}
