概述
WebRTC名称源自网页实时通信(Web Real-Time Communication)的缩写，是一个支持网页浏览器进行实时语音对话或视频对话的技术，是谷歌2010年以6820万美元收购Global IP Solutions公司而获得的一项技术。Google于2011年6月3日开源的即时通讯项目，旨在使其成为客户端视频通话的标准。其实在Google将WebRTC开源之前，微软和苹果各自的通讯产品已占用很大市场份额（如Skype），Google也是为了快速扩大市场，所以将他给开源。在行业内得到了广泛的支持和应用，成为下一代视频通话的标准。更多介绍可以去官网上看。
WebRTC被誉为是web长期开源开发的一个新启元，是近年来Web开发的最重要创新。WebRTC允许Web开发者在其web应用中添加视频聊天或者点对点数据传输，不需要复杂的代码或者昂贵的配置。目前支持Chrome、Firefox和Opera，后续会支持更多的浏览器，它有能力达到数十亿的设备。
目前，WebRTC的应用已经不局限在浏览器与浏览器之间，通过官方提供的SDK，我们可以很容易的实现本地应用间的音视频传输。在Android平台上，我们也非常容易的集成WebRTC框架，用非常简洁的代码就能实现强大、可靠的音视频传输功能。
实现
说明
本文代码修改自meshenger-android
True P2P Voice- and video phone calls without the need for accounts or access to the Internet. There is no discovery mechanism, no meshing and no servers. Just scan each others QR-Code that will contain the contacts IP address. This works in many local networks such as community mesh networks, company networks or at home.
翻译如下:
真正的 P2P 语音和视频电话呼叫，无需帐户或访问互联网。 没有发现机制，没有网格化，也没有服务器。 只需相互扫描包含联系人 IP 地址的二维码即可。 这适用于许多本地网络，例如社区网状网络、公司网络或家庭网络。
版本: meshenger-android-3.0.3 最后的JAVA版本, 最新版本已经改用kotlin
基本情况:
功能满足一个局域网P2P的视频通话功能
- 二维码身份生成-----正常
- 二维码扫码添加通讯录-----正常
- 连接发起通话------异常
主要问题在于无法创建两端之间的Socket连接, 与WebRTC本身无关 - 通讯加解密 ----- 异常
- 视频通话 ---- 只显示对方视频不显示自身

一些问题
首先是源码中Socket连接的问题
Utils.java 与IPV6有关, 这里改成了IPV4.
并在后续的网络相关部分改为使用IP地址.
public static List<InetSocketAddress> getAddressPermutations(String contact_mac, int port) {
byte[] contact_mac_bytes = Utils.macAddressToBytes(contact_mac);
ArrayList<InetSocketAddress> addrs = new ArrayList<InetSocketAddress>();
try {
List<NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
for (NetworkInterface nif : all) {
if (nif.isLoopback()) {
continue;
}
for (InterfaceAddress ia : nif.getInterfaceAddresses()) {
InetAddress addr = ia.getAddress();
if (addr.isLoopbackAddress()) {
continue;
}
android.util.Log.d("Utils", "getAddressPermutations " + addr.getHostName() + "," + addr.getHostAddress() + ",");
if (addr instanceof Inet4Address) {
addrs.add(new InetSocketAddress(addr, port));
/*Inet6Address addr6 = (Inet6Address) addr;
byte[] extracted_mac = getEUI64MAC(addr6);
if (extracted_mac != null && Arrays.equals(extracted_mac, nif.getHardwareAddress())) {
// We found the interface MAC address in the IPv6 assigned to that interface in the EUI-64 scheme.
// Now assume that the contact has an address with the same scheme.
InetAddress new_addr = createEUI64Address(addr6, contact_mac_bytes);
if (new_addr != null) {
addrs.add(new InetSocketAddress(new_addr, port));
}
}*/
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
增加本地摄像头预览显示
方法是传入本地的SurfaceViewRenderer并修改getVideoTrack
private boolean enablePreview = true;
private VideoTrack getVideoTrack() {
this.capturer = createCapturer();
if(!enablePreview) {
return factory.createVideoTrack("video1", factory.createVideoSource(false));
}else {
VideoSource videoSource = factory.createVideoSource(false);
//EglBase.Context eglBaseContext = EglBase.create().getEglBaseContext();
SurfaceTextureHelper surfaceTextureHelper = SurfaceTextureHelper.create("CaptureThread", eglCtxLocal);
capturer.initialize(surfaceTextureHelper, App.getApp(), videoSource.getCapturerObserver());
//capturer.startCapture(480, 640, 30);
VideoTrack track = factory.createVideoTrack("video1", videoSource);
track.addSink(localRenderer);
return track;
}
}
初始化方式问题导致无正常回调
constraints = new MediaConstraints();
constraints.optional.add(new MediaConstraints.KeyValuePair("offerToReceiveAudio", "true"));
constraints.optional.add(new MediaConstraints.KeyValuePair("offerToReceiveVideo", "true"));
constraints.optional.add(new MediaConstraints.KeyValuePair("DtlsSrtpKeyAgreement", "true"));
//方式1:
PeerConnectionFactory.initialize(PeerConnectionFactory
.InitializationOptions.builder(context)
.createInitializationOptions());
factory = PeerConnectionFactory.builder().createPeerConnectionFactory();
//方式2:
PeerConnectionFactory.initialize(PeerConnectionFactory.InitializationOptions.builder(context).createInitializationOptions());
PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();
DefaultVideoEncoderFactory enVdf = new DefaultVideoEncoderFactory(eglCtxRemote, true, true);
VideoDecoderFactory deVdf = new DefaultVideoDecoderFactory(eglCtxRemote);
factory = PeerConnectionFactory.builder()
.setOptions(options)
.setVideoEncoderFactory(enVdf)
.setVideoDecoderFactory(deVdf)
.createPeerConnectionFactory();
方式1 会导致呼出时的错误如下
connection.createOffer(new DefaultSdpObserver() {
@Override
public void onCreateSuccess(SessionDescription sessionDescription) {
log("Outgoing.onCreateSuccess");
super.onCreateSuccess(sessionDescription);
connection.setLocalDescription(new DefaultSdpObserver(){
@Override
public void onSetFailure(String s) {
super.onSetFailure(s);
//出错时的LOG:
//onSetFailure s=
//Failed to set local offer sdp:
//Failed to set local video description recv parameters for m-section with mid='video'.
log("Outgoing.onSetFailure s=" + s);
}
}, sessionDescription);
}
}, constraints);
多次调用PeerConnection.close()会导致崩溃
