采集摄像头

                captureAndroid = CameraUtil.createVideoCapture(context);
                surfaceTextureHelper = SurfaceTextureHelper.create("CaptureThread", eglBase.getEglBaseContext());
                videoSource = peerConnectionFactory.createVideoSource(false);

                captureAndroid.initialize(surfaceTextureHelper, context, videoSource.getCapturerObserver());
                captureAndroid.startCapture(VIDEO_RESOLUTION_WIDTH, VIDEO_RESOLUTION_HEIGHT, FPS);

                localVideoTrack = peerConnectionFactory.createVideoTrack(VIDEO_TRACK_ID, videoSource);
                localVideoTrack.setEnabled(true);
                if (surfaceViewRenderer != null) {
                    ProxyVideoSink videoSink = new ProxyVideoSink();
                    videoSink.setTarget(surfaceViewRenderer);
                    localVideoTrack.addSink(videoSink);
                }

采集本地录制

1.开启屏幕共享服务

    private void DeviceManager(Context context) {
        AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
        BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        if (Build.VERSION.SDK_INT >= 21) {
            mediaProjectionManager = (MediaProjectionManager) context.getSystemService(Context.MEDIA_PROJECTION_SERVICE);
        } else {
            Toast.makeText(context, "您的设备不支持屏幕共享", Toast.LENGTH_SHORT).show();
        }
    }

2.获取屏幕录制的流

    public void startScreenCapture(Activity activity) {
        if (mediaProjectionManager == null) {
            Toast.makeText(this, "截屏服务不可用", Toast.LENGTH_SHORT).show();
            return;
        }
        Intent intent = null;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
            intent = mediaProjectionManager.createScreenCaptureIntent();
            activity.startActivityForResult(intent, SCREEN_CODE);
        }

    }

3.推送本地屏幕录制

                captureAndroid = new ScreenCapturerAndroid(intent, new MediaProjection.Callback() {
                    @Override
                    public void onStop() {
                        super.onStop();
                    }
                });
                videoSource = peerConnectionFactory.createVideoSource(true);
                surfaceTextureHelper = SurfaceTextureHelper.create("CaptureThread", eglBase.getEglBaseContext());
                captureAndroid.initialize(surfaceTextureHelper, context, videoSource.getCapturerObserver());
                captureAndroid.startCapture(VIDEO_RESOLUTION_WIDTH, VIDEO_RESOLUTION_HEIGHT, FPS);
                localVideoTrack = peerConnectionFactory.createVideoTrack(VIDEO_TRACK_ID, videoSource);
                localVideoTrack.setEnabled(true);
