我正在尝试使用 android mediaplayer 类播放存储在我的 sdcard 中的本地 m3u8 文件。m3u8 文件和 .ts 文件位于同一目录中。当我从中打开 m3u8 时，像 MXPlayer 这样的第三方播放器会加入 ts 文件并播放视频。但是使用 android mediaplayer 类会抛出以下错误`

Unable to to create media player error: setDataSourceFD failed.: status=0x80000000 java.io.IOException: setDataSourceFD failed.: status=0x80000000 at android.media.MediaPlayer.setDataSource(Native Method) at android.media.MediaPlayer.setDataSource(MediaPlayer.java:1204) at com.tcs.hlsvideo.StreamingPlayer.playVideo(StreamingPlayer.java:87) at com.tcs.hlsvideo.StreamingPlayer.surfaceCreated(StreamingPlayer.java:148) at android.view.SurfaceView.updateWindow(SurfaceView.java:609) at android.view.SurfaceView.access$000(SurfaceView.java:86) at android.view.SurfaceView$3.onPreDraw(SurfaceView.java:178) at android.view.ViewTreeObserver.dispatchOnPreDraw(ViewTreeObserver.java:707) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1981) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1143) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:4667) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:725) at android.view.Choreographer.doCallbacks(Choreographer.java:555) at android.view.Choreographer.doFrame(Choreographer.java:525) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:711) at android.os.Handler.handleCallback(Handler.java:615) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4960) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1038) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:805) at dalvik.system.NativeStart.main(Native Method) setDataSourceFD failed.: status=0x80000000

我用过的代码是

private static final String TAG = StreamingPlayer.class.getSimpleName();

private String formatedIpAddress;

private int mVideoWidth;
private int mVideoHeight;
private MediaPlayer mMediaPlayer;
private SurfaceView mPreview;
private SurfaceHolder holder;
private String path;

//private boolean mIsVideoSizeKnown = false;
private boolean mIsVideoReadyToBePlayed = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mPreview = new SurfaceView(this);
    holder = mPreview.getHolder();
    holder.addCallback(this);
    setContentView(mPreview);

    WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
    int ipAddress = wifiManager.getConnectionInfo().getIpAddress();
    formatedIpAddress = String.format("%d.%d.%d.%d", (ipAddress & 0xff),
            (ipAddress >> 8 & 0xff), (ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));

    Log.d(TAG, formatedIpAddress);

}

private void playVideo() {
    doCleanUp();
    try {

        //local m3u8 file
        path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/ts/prog_index.m3u8";

        if (path == "") {

最佳答案

我不确定，但看起来 M3U8 文件不是媒体文件。它是一种播放列表文件格式。这意味着您必须解析它，从中获取媒体文件的路径并播放您获得的文件之一。

这是格式的简短描述 http://www.gravlab.com/2013/07/05/what-is-an-m3u8-file/ .

要了解如何解析它，请查看此答案:Parsing HLS m3u8 file using regular expressions
