如何播放本地m3u8文件？

Question

My task is to download some part of HLS stream from server and play it locally in android app.

I've download required .ts chunks and formed playlist:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:10.000000,
/storage/emulated/0/Android/data/com.example.myapp/files/savedMovies/chunk0.ts
#EXTINF:10.000000,
/storage/emulated/0/Android/data/com.example.myapp/files/savedMovies/chunk1.ts
#EXTINF:10.000000,
/storage/emulated/0/Android/data/com.example.myapp/files/savedMovies/chunk2.ts
#EXTINF:10.000000,
/storage/emulated/0/Android/data/com.example.myapp/files/savedMovies/chunk3.ts
#EXT-X-ENDLIST

Next, I've passed the link to playlist to android.media.MediaPlayer instance:

String fileLink = "/storage/emulated/0/Android/data/com.example.myapp/files/savedMovies/savedPlaylist.ts";
mediaPlayer.setDataSource(fileLink);

As result I've received such exception:

The same thing is happening if I pass to player file's path with original server's playlist saved locally (with http links to chunks)

I've tried to play local file in VLC player:

intent.setDataAndType(Uri.parse(fileUrl), "video/m3u8");

But causes an error too (both with local and http links)

Can anyone help me with this?

I've already checked permissions:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

My code:

private void playVideo(String fileUrl) {
    surfaceView.setVisibility(View.VISIBLE);

    this.fileUrl = fileUrl;

    holder = surfaceView.getHolder();
    holder.addCallback(this);
}

@Override
public void onPrepared(MediaPlayer player) {
    mediaPlayer.start();
}


@Override
public void surfaceCreated(SurfaceHolder holder) {
    try {
        mediaPlayer = new MediaPlayer();

        File file = new File(fileUrl);
        FileInputStream inputStream = new FileInputStream(file);
        mediaPlayer.reset();
        mediaPlayer.setDataSource(inputStream.getFD());
        inputStream.close();

        mediaPlayer.setDisplay(holder);

        mediaPlayer.prepare();

        mediaPlayer.setOnErrorListener(this);
        mediaPlayer.setOnBufferingUpdateListener(this);
        mediaPlayer.setOnCompletionListener(this);
        mediaPlayer.setOnPreparedListener(this);
        mediaPlayer.setOnVideoSizeChangedListener(this);
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    } catch (IOException e) {
        e.printStackTrace();
    }
}


@Override
public void onPrepared(MediaPlayer player) {
    mediaPlayer.start();
}

Answer 1

As I understand MediaPlayer is unable to play local m3u8 files.

I used ExoPlayer instead, works well now
