實(shí)現(xiàn)實(shí)時(shí)視頻聊天功能的源碼在Android平臺(tái)上可以使用WebRTC技術(shù)。下面是一個(gè)簡(jiǎn)單的示例：

  1. 添加依賴項(xiàng)

在項(xiàng)目的build.gradle文件中添加以下依賴項(xiàng)：

dependencies {
implementation 'org.webrtc:google-webrtc:1.0.32006'
}
  1. 創(chuàng)建RTC連接
PeerConnectionFactory.initialize(PeerConnectionFactory.InitializationOptions.builder(context).createInitializationOptions());
PeerConnectionFactory factory = new PeerConnectionFactory();
// 創(chuàng)建本地視頻源
VideoCapturer videoCapturer = createVideoCapturer();
VideoSource videoSource = factory.createVideoSource(videoCapturer.isScreencast());
LocalVideoTrack localVideoTrack = factory.createVideoTrack("video_track", videoSource);
// 創(chuàng)建本地音頻源
AudioSource audioSource = factory.createAudioSource(new MediaConstraints());
LocalAudioTrack localAudioTrack = factory.createAudioTrack("audio_track", audioSource);
// 創(chuàng)建本地媒體流
MediaStream localStream = factory.createLocalMediaStream("local_stream");
localStream.addTrack(localVideoTrack);
localStream.addTrack(localAudioTrack);
// 創(chuàng)建PeerConnection
PeerConnection.RTCConfiguration rtcConfig = new PeerConnection.RTCConfiguration(Collections.singletonList(new PeerConnection.IceServer("stun:stun.l.google.com:19302")));
PeerConnection.Observer pcObserver = new PeerConnection.Observer() {
// 實(shí)現(xiàn)對(duì)方視頻流的回調(diào)
@Override
public void onAddStream(MediaStream mediaStream) {
// 獲取對(duì)方的視頻軌道
VideoTrack remoteVideoTrack = mediaStream.videoTracks.getFirst();
// 顯示對(duì)方的視頻
remoteVideoTrack.addSink(remoteVideoView);
}
// 其他回調(diào)方法...
};
PeerConnection peerConnection = factory.createPeerConnection(rtcConfig, pcObserver);
peerConnection.addStream(localStream);
  1. 發(fā)起視頻通話
// 創(chuàng)建SessionDescription
SdpObserver sdpObserver = new SdpObserver() {
@Override
public void onCreateSuccess(SessionDescription sessionDescription) {
// 設(shè)置本地的SessionDescription
peerConnection.setLocalDescription(sdpObserver, sessionDescription);
// 發(fā)送本地的SessionDescription到對(duì)方
sendSessionDescription(sessionDescription);
}
// 其他回調(diào)方法...
};
peerConnection.createOffer(sdpObserver, new MediaConstraints());
  1. 接收視頻通話
// 接收對(duì)方的SessionDescription
SessionDescription remoteDescription = receiveSessionDescription();
peerConnection.setRemoteDescription(sdpObserver, remoteDescription);
// 創(chuàng)建Answer
peerConnection.createAnswer(sdpObserver, new MediaConstraints());
  1. 建立視頻連接
// 設(shè)置對(duì)方的SessionDescription
peerConnection.setRemoteDescription(sdpObserver, remoteDescription);
// 添加ICE候選
peerConnection.addIceCandidate(candidate);
// 建立連接
peerConnection.createAnswer(sdpObserver, new MediaConstraints());

這只是一個(gè)簡(jiǎn)單的示例，實(shí)際的視頻聊天功能需要處理更多的細(xì)節(jié)，例如處理ICE候選、處理連接狀態(tài)變化、處理媒體流的傳輸?shù)取Ｍ暾膶?shí)現(xiàn)可能需要更多的代碼和邏輯。
