Exoplayer播放m3u8文件
Exoplayer播放m3u8文件
提问于 2015-07-14 22:00:12
在尝试了多种使用m3u8文件的方式使用、videoview和mediaplayer后，我决定放弃。每次我播放m3u8文件时，我只听到声音。(请不要写堆栈溢出的urls，回答我的问题。)我已经问过他们了，我终于知道的外星可能就是我要找的那个。然而，系外玩家似乎是一个新手，我找不到任何适当的教程。有人说我自己是个新手，所有关于追踪器和布拉贝拉的话题对我来说都太复杂了。我只希望能够从我的应用程序中的不同urls打开所有的文件，而不需要将它们传递给vlc或任何外部意图。
为了记录在案，我使用KitKat和更高版本。所以系外玩家应该是可实现的。
因此，我迫切需要的是一个简单教程，说明我如何使用外挂播放器或其他方式播放m3u8文件，显示视频，播放音频和，而不仅仅是播放其中的一个。请不要将我链接到google dev上的系外玩家页面。我也去过那里。
(预先谢谢:)

在Android 4.1+上，您可以使用这个库https://github.com/brianwernick/ExoMedia/。在Read页面上提到的示例应该足以让您入门。我已经复制了该代码片段，并进行了一些添加/修改。
private void setupVideoView() {
EMVideoView emVideoView = (EMVideoView)findViewById(R.id.video_play_activity_video_view);
emVideoView.setOnPreparedListener(this);
//Enter your m3u8 URL below
emVideoView.setVideoURI(Uri.parse("http://SOMESERVER/playlist.m3u8"));
}
@Override
public void onPrepared(MediaPlayer mp) {
//Starts the video playback as soon as it is ready
emVideoView.start();
}
@Override
public void onPause() {
super.onPause();
//Pause Video Playback
emVideoView.pause();

我创建了一个演示应用程序来播放m3u8媒体文件
首先，将gradle依赖项添加到文件中
compile 'com.google.android.exoplayer:exoplayer:r2.4.0'创建一个简单的布局文件，以存储master.m3u8路径作为输入和SimpleExoPlayerView视图来播放下载的文件。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout mlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<android.support.design.widget.TextInputEditText
android:layout_marginTop="15dp"
android:layout_width="match_parent"
android:id="@+id/mediaPath"
android:layout_height="56dp" />
<android.support.v7.widget.AppCompatButton
android:id="@+id/play"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:layout_below="@+id/mediaPath"
android:background="@color/colorAccent"
android:layout_width="match_parent"
android:text="Play"
android:layout_height="56dp" />
<com.google.android.exoplayer2.ui.SimpleExoPlayerView
android:layout_below="@+id/play"
android:id="@+id/video_view"
android:layout_marginTop="5dp"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>创建一个简单的ExoPlayer活动来播放文件。

这是使用m3u8 Lib (希望帮助https://github.com/karim23/SimpleStreamPlayer/tree/master )流ExoPlayer文件的最简单方法
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = getApplicationContext();
setContentView(R.layout.activity_main);
//change the live streaming URL with yours.
contentUri = "http://abclive.abcnews.com/i/abc_live4@136330/index_1200_av-b.m3u8?sd=10&b=1200&rebase=on";
// contentType = DemoUtil.TYPE_HLS;
final Intent intent = new Intent(context, VideoPlayerActivity.class).setData(Uri.parse(contentUri))
.putExtra(VideoPlayerActivity.CONTENT_ID_EXTRA, -1)
//Change the type according to the live streaming extension.
.putExtra(VideoPlayerActivity.CONTENT_TYPE_EXTRA, DemoUtil.TYPE_HLS);
liveStreamingTv =(TextView)findViewById(R.id.mainActivity_liveStreamingTv);
liveStreamingTv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startActivity(intent);
}
});
