GoPro stream latency on android app

Problem:
I made an android apk for displaying GoPro stream, but when I start it, I have 3 or 4 seconds of latencies.
But when I change the framerate using the GoPro, it seems to reload the stream and the latency go back to 1 second or less.
So I tried using Wifi command to change framerate but it doesn't work.
I suppose the problem is coming from my settings because it keeps packets it shouldn't keep.

Details:
To receive that stream, I'm using libvlc and FFmpeg-kit :

ArrayList _Options = new ArrayList();
_Options.add("--file-caching=2000");
_Options.add("--network-caching=150");
_Options.add("--clock-jitter=0");
_Options.add("--live-caching=200");
_Options.add("--clock-synchro=0");
_Options.add("--drop-late-frames");
_Options.add("--skip-frames");
_Options.add("-vvv");
_myLibVlc = new LibVLC(findViewById(android.R.id.content).getContext(), _Options);
_myPlayer = new MediaPlayer(_myLibVlc);
_myVout = _myPlayer.getVLCVout();

private String cmd = "-an -flags low_delay -flags2 fast -fflags nobuffer -f:v mpegts -probesize 2048 -r 12 -i udp://10.5.5.100:8554 -max_delay 1000 -preset ultrafast -vcodec libx264 -tune zerolatency -f mpegts -vcodec copy udp://127.0.0.1:12345";

FFmpegKit.execute(cmd);

• GoPro Camera(s):
  GoPro HERO 5

• Firmware Version:
  Android 12
  libvlc : org.videolan.android:libvlc-all:3.1.12
  FFmpeg-kit : libs/ffmpeg-kit-full-4.5.1-1.aar

• Steps to reproduce:
  Launch GoPro stream with latency and change the video mode framerate to 24 (even if it's already 24)

• Happens every time? [Y/N]: Sometimes but not everytime

Use Exoplayer with LoadControl and set minBuffer to 900ms and maxBuffer to 1100ms. For me it works with Hero5 and Hero8 without problems.
Example: PreviewActivity.java

And by the way: ffmpeg-kit-min is enough for that. This will make the APK file smaller.

Thanks for the tip

But I kind of figured out that my options weren't working because I was declaring them like every stack overflow answer.
Though, it worked when I did it that way :

    ArrayList<String> _Options = new ArrayList<>();
    _Options.add("--file-caching=2000");
    _Options.add("-vvv");
    _myLibVlc = new LibVLC(findViewById(android.R.id.content).getContext(), _Options);
    _myPlayer = new MediaPlayer(_myLibVlc);
    _myPlayer.getVLCVout();
    _myPlayer.attachViews(_myVideoView, null, false, false);
    Media media = new Media(_myLibVlc, Uri.parse("udp://@:12345"));
    media.setHWDecoderEnabled(true, true);
    media.addOption(":file-caching=0");
    media.addOption(":network-caching=0");
    media.addOption(":live-caching=0");
    media.addOption(":clock-jitter=0");
    media.addOption(":clock-synchro=0");
    media.addOption(":drop-late-frames");
    media.addOption(":skip-frames");
    _myPlayer.setMedia(media);
    //_myPlayer.setRate(1.5f);
    _myPlayer.play();

That makes me happy!
What latencies do you have now?
I have about a second latency with my solution.

Best regards

I also have about a second (which is better than 3-4 seconds that were getting longer over time)
But if I try to set playback x2, it nearly catch up to be around 300ms, then it stop because the buffer is empty
(normal since I'm trying to play x2 with a live)
