All Implemented Interfaces:

MediaSession.StreamHandler

public class CameraStreamHandler
extends DefaultStreamHandler

A managed camera2 MediaSession.StreamHandler using MediaCodec for encoding the Camera stream to h264 frames and uploading to MediaSession.MediaSink. A Typical use case would look like:

   
     session
         .addStream(new MediaSession.CameraStreamBuilder(CHANNEL_NAME,
             MediaSession.VideoQuality.HD, CameraSelector.DEFAULT_FRONT_CAMERA))
         .observe(this, videoHandler -> {
           if (null == videoHandler) {
             Log.w(TAG, "onCreate: unable to start the stream");
             return;
           }

           videoHandler.start();

           videoHandler.bindToLifecycle(this, this);

           binding.cameraDisable.setOnClickListener(v -> videoHandler.stop());
         });
