我希望在我的应用中实施Google ExoPlayer
。他们的文档对我来说似乎很模糊,而我正在寻找的是从URL播放视频,没有复杂的自定义设置或类似的东西。 Haven没有找到关于如何做的任何教程。他们在git上的例子对于我需要的东西来说太复杂了,因为我不熟悉视频流,所以我并不了解。我到目前为止所做的就是显示com.google.android.exoplayer.AspectRatioFrameLayout
。
基本上,我有一个URL。我需要播放视频,并在用户翻转屏幕时处理onConfigurationChanged
。
有人可以帮忙吗?

ExoMedia库将exoplayer包装在更简单的api中,并提供用于布局的视频视图。请参阅github上的用法示例:https://github.com/brianwernick/ExoMedia/

如果您只想显示视频网址,VideoView会更好。 ExoPlayer需要一些开发工作,即使是调用它的简单实例也是如此。但是,有一个优点是更快,更有效的播放,由活跃的开源社区支持。 This link为实现提供了很好的理由,提供了切换到ExoPlayer的充分理由。 当然,检查official developer guide,更新版本有拆分模块,以便更简单的实施。

Exoplayer是一个非常高级的库。即使编写最少的代码也需要40至50行代码。因此,如果您真的想用剑将洋葱切碎,请直接复制意大利面:
//manifest.xml
<manifest ...>
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:usesCleartextTraffic="true"
...>
...
</application>
</manifest>
//app/build.gradle
apply plugin: 'com.android.application'
android {
...
compileOptions {
sourceCompatibility = 1.8
targetCompatibility = 1.8
}
}
dependencies {
...
implementation 'com.google.android.exoplayer:exoplayer:2.10.4'
}
protected void onCreate(Bundle savedInstanceState) {
...
Context ctx =this;
String CONTENT_URL = "https://www.radiantmediaplayer.com/media/bbb-360p.mp4";
int playerID=R.id.pv_main;
int appNameStringRes = R.string.app_name;
startPlayingVideo(this,CONTENT_URL,playerID,appNameStringRes);
}
//
private void startPlayingVideo(Context ctx , String CONTENT_URL, int playerID, String appNameRes) {
PlayerView pvMain = ctx.findViewById(playerID);
//BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
//TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
//TrackSelector trackSelectorDef = new DefaultTrackSelector(videoTrackSelectionFactory);
TrackSelector trackSelectorDef = new DefaultTrackSelector();
SimpleExoPlayer absPlayerInternal = ExoPlayerFactory.newSimpleInstance(ctx, trackSelectorDef);
String userAgent = Util.getUserAgent(ctx, ctx.getString(appNameRes));
DefaultDataSourceFactory defdataSourceFactory = new DefaultDataSourceFactory(ctx,userAgent);
Uri uriOfContentUrl = Uri.parse(CONTENT_URL);
MediaSource mediaSource = new ProgressiveMediaSource.Factory(defdataSourceFactory).createMediaSource(uriOfContentUrl);
absPlayerInternal.prepare(mediaSource);
absPlayerInternal.setPlayWhenReady(true);
pvMain.setPlayer(absPlayerInternal);
}
private void stopPlayer(PlayerView pv,SimpleExoPlayer absPlayer){
pv.setPlayer(null);
absPlayer.release();
absPlayer = null;
}
只需在活动布局中添加player view
,在startPlayingVideo(...)
中调用onCreate()
并在stopPlayer()
中调用onStop()
即可。我不是专家,但是如果您愿意,我可以尝试解释一下,但是您没有要求任何复杂的内容,因此这里只是代码
