ExoPlayer usage

ExoPlayer can be used to play audio and video content from local files, network streaming, and other sources. ExoPlayer supports a variety of streaming protocols, including common HLS, DASH, SmoothStreaming, etc., and also supports common audio and video formats. ExoPlayer can be used to implement a customized player interface and interactive logic, and can also be extended to achieve specific functions and customized requirements. It also provides rich APIs and documentation to facilitate developers to carry out customized development and integration.

1. Add the ExoPlayer library dependency in the project's build.gradle file:

 implementation 'com.google.android.exoplayer:exoplayer-core:2.15.1' implementation 'com.google.android.exoplayer:exoplayer-dash:2.15.1' // 如果需要支持DASH协议

2. Add a SimpleExoPlayerView in the layout file to display the video:

 <com.google.android.exoplayer2.ui.SimpleExoPlayerView android:id="@+id/simpleExoPlayerView" android:layout_width="match_parent" android:layout_height="match_parent"/>

3. Initialize ExoPlayer in Activity or Fragment and set the data source:

 SimpleExoPlayerView simpleExoPlayerView = findViewById(R.id.simpleExoPlayerView); SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(this); simpleExoPlayerView.setPlayer(player); String videoUrl = "https://video.699pic.com/videos/88/66/46/a_ZViI5evHpDKS1699886646_10s.mp4"; Uri uri = Uri.parse(videoUrl); MediaSource mediaSource = new ExtractorMediaSource.Factory(new DefaultDataSourceFactory(this, "exoplayer-codelab")).createMediaSource(uri); player.prepare(mediaSource); player.setPlayWhenReady(true); player.play();

4. Other methods:

• Play video: player.play()
• Pause the video: player.pause()
• Stop playback: player.stop()
• seekTo: player.seekTo(time)

Example of using ExoPlayer's custom components to customize the player's behavior and appearance:

Use a custom layout file to define the appearance of ExoPlayer, such as the control bar, play button, etc. In the layout file, use the controls and properties provided by ExoPlayer to customize the appearance.

 <com.google.android.exoplayer2.ui.PlayerView android:id="@+id/player_view" android:layout_width="match_parent" android:layout_height="match_parent" app:use_controller="true" app:controller_layout_id="@layout/custom_controller_layout" app:fastforward_increment="10000" app:rewind_increment="10000" />

You can customize the ExoPlayer control bar behavior through a custom PlayerControlView. You can listen to various events of the control bar and handle them accordingly.

 playerView = findViewById(R.id.player_view); player = ExoPlayerFactory.newSimpleInstance(this); playerView.setPlayer(player); playerControlView = playerView.findViewById(R.id.exo_controller); playerControlView.setPlaybackPreparer(new PlaybackPreparer() { @Override public void preparePlayback() { // 在这里处理准备播放的逻辑} }); playerControlView.setControlDispatcher(new ControlDispatcher() { @Override public boolean dispatchSetPlayWhenReady(Player player, boolean playWhenReady) { // 在这里处理播放/暂停按钮的点击事件return true; } });
