使用以下代码设置视频和音轨：
public void setCamera() {
localMS = factory.createLocalMediaStream("ARDAMS");
if (pcParams.videoCallEnabled) {
MediaConstraints videoConstraints = new MediaConstraints();
videoConstraints.mandatory.add(new MediaConstraints.KeyValuePair("maxHeight", Integer.toString(pcParams.videoHeight)));
videoConstraints.mandatory.add(new MediaConstraints.KeyValuePair("maxWidth", Integer.toString(pcParams.videoWidth)));
videoConstraints.mandatory.add(new MediaConstraints.KeyValuePair("maxFrameRate", Integer.toString(pcParams.videoFps)));
videoConstraints.mandatory.add(new MediaConstraints.KeyValuePair("minFrameRate", Integer.toString(pcParams.videoFps)));
getVideoCapturer();
videoSource = factory.createVideoSource(videoCapturer, videoConstraints);
videoTrack = factory.createVideoTrack("ARDAMSv0", videoSource);
localMS.addTrack(videoTrack);
}
audioSource = factory.createAudioSource(new MediaConstraints());
audioTrack = factory.createAudioTrack("ARDAMSa0", audioSource);
localMS.addTrack(audioTrack);
mListener.onLocalStream(localMS, true);
}
使用下面的代码来检索 VideoCapturer：
private void createCapturer(CameraEnumerator enumerator) {
final String[] deviceNames = enumerator.getDeviceNames();
Logging.d(TAG, "Looking for front facing cameras.");
for (String deviceName : deviceNames) {
if (enumerator.isFrontFacing(deviceName)) {
Logging.d(TAG, "Creating front facing camera capturer.");
videoCapturer = enumerator.createCapturer(deviceName, null);
if (videoCapturer != null) {
System.out.println("deviceName = " + deviceName);
return;
}
}
}
// Front facing camera not found, try something else
Logging.d(TAG, "Looking for other cameras.");
for (String deviceName : deviceNames) {
if (!enumerator.isFrontFacing(deviceName)) {
Logging.d(TAG, "Creating other camera capturer.");
videoCapturer = enumerator.createCapturer(deviceName, null);
if (videoCapturer != null) {
return;
}
}
}
}
使用以下代码更新自定义 VideoRenderGui：
localStream.videoTracks.get(0).addRenderer(new VideoRenderer(localRender));
localVideoRenderGui.update(localRender,
LOCAL_X_CONNECTING, LOCAL_Y_CONNECTING,
LOCAL_WIDTH_CONNECTING, LOCAL_HEIGHT_CONNECTING,
scalingType, true);
