android - WebRTC - 创建 PeerConnectionFactory 对象

Question

我之前使用过 WebRTC 1.0.22672，现在我切换到最新版本 1.0.26885。之前我使用此代码创建 PeerConnectionFactory 和 VideoSource 对象，并且工作正常:

PeerConnectionFactory.InitializationOptions initializationOptions =
            PeerConnectionFactory.InitializationOptions.builder(this)
                    .createInitializationOptions();
    PeerConnectionFactory.initialize(initializationOptions);

    //Create a new PeerConnectionFactory instance - using Hardware encoder and decoder.
    PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();
    DefaultVideoEncoderFactory defaultVideoEncoderFactory = new DefaultVideoEncoderFactory(
            rootEglBase.getEglBaseContext(),  /* enableIntelVp8Encoder */true,  /* enableH264HighProfile */true);
    DefaultVideoDecoderFactory defaultVideoDecoderFactory = new DefaultVideoDecoderFactory(rootEglBase.getEglBaseContext());
    peerConnectionFactory = new PeerConnectionFactory(options, defaultVideoEncoderFactory, defaultVideoDecoderFactory);


    //Now create a VideoCapturer instance.
    VideoCapturer videoCapturerAndroid;
    videoCapturerAndroid = createCameraCapturer(new Camera1Enumerator(false));


    //Create MediaConstraints - Will be useful for specifying video and audio constraints.
    audioConstraints = new MediaConstraints();
    videoConstraints = new MediaConstraints();

    //Create a VideoSource instance
    if (videoCapturerAndroid != null) {
        videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid);
    }

但在最新版本中，我在 new PeerConnectionFactory... 上有两个错误上面写着:

'PeerConnectionFactory(long)' is not public in 'org.webrtc.PeerConnectionFactory'. Cannot be accessed from outside package

以及peerConnectionFactory.createVideoSource...

那个syas:

createVideoSource (boolean) in PeerConnectionFactory cannot be applied to (org.webrtc.VideoCapturer)  

如何解决这些错误？

有人可以告诉我为什么没有 Android 原生 WebRTC 的文档或更改日志吗？!

Answer 1

How can i solve these errors?

WebRTC 最新版本中已弃用或删除了许多 API。请执行以下步骤来解决这些错误。

第 1 步:更改代码

peerConnectionFactory = new PeerConnectionFactory(options, defaultVideoEncoderFactory, defaultVideoDecoderFactory);

至

peerConnectionFactory = PeerConnectionFactory.builder()
        .setOptions(options)
        .setVideoEncoderFactory(defaultVideoEncoderFactory)
        .setVideoDecoderFactory(defaultVideoDecoderFactory)
        .createPeerConnectionFactory();

第 2 步:更改代码

//Create a VideoSource instance
if (videoCapturerAndroid != null) {
    videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid);
}

至

//Create a VideoSource instance
if (videoCapturerAndroid != null) {
    SurfaceTextureHelper surfaceTextureHelper = SurfaceTextureHelper.create("CaptureThread", rootEglBase.getEglBaseContext());
    videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid.isScreencast());
    videoCapturerAndroid.initialize(surfaceTextureHelper, getApplicationContext(), videoSource.getCapturerObserver());
}

Can someone tell my WHY there is no documentation or change-log for android native WebRTC?
