java - 如何在 Exoplayer 中编写重复模式？

Question

我正在尝试播放 m3u8 格式的电视广播，但在某些 m3u 列表中，他们的视频时间有限，即每 50 秒暂停一次，我手动按播放以保持播放，有什么办法可以播放自动地？

我正在使用 Exoplayer 2.7.3

.xml

    app:controller_layout_id="@layout/custom_controller"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:resize_mode="fill"
    app:hide_on_touch="true"
    >
    <ProgressBar
        android:id="@+id/progress"
        android:layout_gravity="center"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="gone"
        android:layout_marginEnd="0dp"
        android:layout_marginRight="0dp"
        android:layout_marginBottom="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</com.google.android.exoplayer2.ui.SimpleExoPlayerView>

修改 onPlayerStateChanged 如下：

            if (playbackState == ExoPlayer.STATE_BUFFERING){
                progressBar.setVisibility(View.VISIBLE);
            }else if (playbackState == ExoPlayer.STATE_ENDED) {
                player.prepare(hlsMediaSource);
            }else {
                progressBar.setVisibility(View.INVISIBLE);
            }
