Java – Reduces latency when playing rtp streams with libvlc on Android

I’m using LibVLC version 3.0.0 to play incoming mpeg2ts streams over RTP on Android. The code is as follows:

SurfaceView playerView; Initialized somewhere before    

LibVLC libVlc = new LibVLC(context, arrayListOf("--file-caching=150", "--network-caching=150",
                    "--clock-jitter=0", "--live-caching=150", "--clock-synchro=0",
                    "-vvv", "--drop-late-frames", "--skip-frames"));
MediaPlayer player = new MediaPlayer(libVlc);
IVLCVout vout = player.getVLCVout();
vout.setVideoView(playerView);
vout.attachViews();
Media media = new Media(libVlc, Uri.parse("rtp://@:" + UDP_PORT + "/"));
player.setMedia(media);
player.play();

This plays the stream, but there is a delay of about 2 seconds. I’m sure the latency can be reduced to ~300ms because other players can play it with this delay. What options should I use to reduce this latency? I know I have to trade it for quality at the cost of quality, but what do I do first?

There is a way to reduce the latency from about 2 seconds to about 200 milliseconds

Workaround:

 ArrayList<String> options = new ArrayList<>();
 options.add("--file-caching=2000");
 options.add("-vvv");

LibVLC mLibVLC = new LibVLC(getApplicationContext(), options);
 MediaPlayer mMediaPlayer =  new MediaPlayer(mLibVLC);

Media media = new Media(mLibVLC, Uri.parse("rtsp://192.168.0.1:1935/myApp/myStream"));
        media.setHWDecoderEnabled(true, false);
        media.addOption(":network-caching=150");
        media.addOption(":clock-jitter=0");
        media.addOption(":clock-synchro=0");

mMediaPlayer.setMedia(media);
 mMediaPlayer.play();

Hope this helps! =)
