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 类会引发以下错误`
无法创建媒体播放器错误：setDataSourceFD 失败。：status=0x80000000 java.io.IOException：setDataSourceFD 失败。：android.media.MediaPlayer.setDataSource 的 status=0x80000000（Native Method）在 android.media.MediaPlayer.setDataSource（MediaPlayer .java:1204) 在 com.tcs.hlsvideo.StreamingPlayer.playVideo(StreamingPlayer.java:87) 在 com.tcs.hlsvideo.StreamingPlayer.surfaceCreated(StreamingPlayer.java:148) 在 android.view.SurfaceView.updateWindow(SurfaceView. java:609) 在 android.view.SurfaceView.access$000(SurfaceView.java:86) 在 android.view.SurfaceView$3.onPreDraw(SurfaceView.java:178) 在 android.view.ViewTreeObserver.dispatchOnPreDraw(ViewTreeObserver.java:707 ) 在 android.view.ViewRootImpl 的 android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1981)。doTraversal(ViewRootImpl.java:1143) 在 android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:4667) 在 android.view.Choreographer$CallbackRecord.run(Choreographer.java:725) 在 android.view.Choreographer.doCallbacks (Choreographer.java:555) 在 android.view.Choreographer.doFrame(Choreographer.java:525) 在 android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:711) 在 android.os.Handler.handleCallback(Handler. java:615) 在 android.os.Handler.dispatchMessage(Handler.java:92) 在 android.os.Looper.loop(Looper.java:137) 在 android.app.ActivityThread.main(ActivityThread.java:4960) 在java.lang.reflect.Method.invokeNative(Native Method) 在 com.android.internal.os.ZygoteInit$MethodAndArgsCaller 的 java.lang.reflect.Method.invoke(Method.java:511)。在 dalvik.system.NativeStart.main（本机方法）的 com.android.internal.os.ZygoteInit.main（ZygoteInit.java:805）处运行（ZygoteInit.java:1038） setDataSourceFD 失败。：状态 = 0x80000000
我使用的代码是
