I’m trying to implement srt subtitles into my videos but I don’t understand how make them work in the new media3

public class VideoPlayerFragment extends Fragment implements View.OnClickListener {

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

and I use

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ui.fragments.VideoPlayerFragment">

    <androidx.media3.ui.PlayerView
        android:id="@+id/videoPlayer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:animateLayoutChanges="false"
        android:background="@color/black"
        app:controller_layout_id="@layout/custom_playback_view"
        app:hide_on_touch="true"
        app:resize_mode="fit"
        app:show_timeout="3000"
        app:shutter_background_color="@color/app_background"
        app:surface_type="surface_view" />
</FrameLayout>

Can someone help me? I have tried some things online but they all use exoplayer2.
If you want help me with code improvement I’m open to suggestions.
Also, app:show_timeout="3000" hides the timebar after 3s and controls after 6 (3s the timebar and 3s for the layout) how can I change it?

P.s. I know fragment is bad for video player, I’ll change it soon
