大纲/内容

WebSocketRTCClient

这里把new出来的2个红色的对象设置到capturer(jni层实现的)

startListening

initialize

3.回调到VidoCapturer

startCapturer

createPeerConnection

CameraSession.Events

void onCameraOpening(); void onCameraError(); void onCameraDisconnected(); void onCameraClosed(); void onByteBufferFrameCaptured(); void onTextureFrameCaptured();

onTextureFrameCaptured

create

MediaStream

PeerConnectionFactory

SurfaceTextureHelper

private final Handler handler; private final EglBase eglBase; private final int oesTextureId; private OnTextureFrameAvailableListener listener;

+ operation1(params):returnType- operation2(params)- operation3()

oesTextureId = GlUtil.generateTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES); surfaceTexture = new SurfaceTexture(oesTextureId); surfaceTexture.setOnFrameAvailableListener(new SurfaceTexture.OnFrameAvailableListener() { @Override public void onFrameAvailable(SurfaceTexture surfaceTexture) { hasPendingTexture = true; tryDeliverTextureFrame(); } });

CameraEnumerator

startCall

CapturerObserver

camera = android.hardware.Camera.open(cameraId);camera.setPreviewTexture(surfaceTextureHelper.getSurfaceTexture());listenForTextureFrames()camera.startPreview();

CallActivity

initalize

createViddeoSource

CameraCapturer

cameraSessionEventsHandler attribute2:type attribute3:type

createMediaStream

1.这里是视频帧回调的起始点(helper类有一个单独的线程)

2.回调传递到session

PeerConnectionClient

AndroidVideoTrackSourceObserver

connectToRoom

onConnectedToRoom
