存储在 Firebase 存储中的 m3u8 文件无法在网络播放器上播放

Question

我已将 m3u8 文件存储在 firebase 云存储中，这是 URL 用于 m3u8 文件

[https://firebasestorage.googleapis.com/v0/b/testing-musicoi.appspot.com/o/MediaContent%2F240p%2F240_out.m3u8?alt=media&token=0f81947b-1df0-4333-ae67-bdf21b4c49cc]

当我在我的计算机上使用 VLC 播放器时，这个 URL 工作得很好，但是当我尝试使用同样的 link 网络播放器时，像这样 HLS media player 它不起作用。此外，我想知道这个 m3u8 URL 不能与 Android Exoplayer 一起使用吗？

Answer 1

网络播放器依赖于 Cross-Origin Resource Sharing，它允许一个域中的脚本访问另一个域中的数据。这会失败，因为您的源域不允许从其他域访问。

您需要配置 Access-Control-Allow-Origin header 以允许 bitmovin.com（和其他域）访问您的文件。

编辑您的 firebase.json 并添加或更改 hosting 部分：

"hosting": {
  "headers": [ {
    "source": "**/*.*",
    "headers": [ {
      "key": "Access-Control-Allow-Origin",
      "value": "*"
    } ]
  } ]
}

见Firebase documentation。

我找到了一个类似的 question，您可能会感兴趣：

First create an exoplayer in your xml file

<com.google.android.exoplayer2.ui.PlayerView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="0sp"
        android:layout_marginStart="20dp"
        android:layout_marginTop="20dp"
        android:layout_marginEnd="20dp"
        android:visibility="gone"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.0" />

"I have set the height as 0 cuz im gonna fix the height programmatically later then declare simple SimpleExoPlayer in your activity as player."

 SimpleExoPlayer player;

"Then in you follow these steps"

//declare your PlayerView 

final PlayerView playerView = mview.findViewById(R.id.video_view);

//your database ref

        final StorageReference storageReference =
                FirebaseStorage.getInstance().getReference("/Post_Video/"+ video + ".mp4");


 player = ExoPlayerFactory.newSimpleInstance(MainActivity.this);
        playerView.setPlayer(player);

        playerView.setVisibility(View.VISIBLE);

        playerView.getLayoutParams().height=550;
        playerView.getLayoutParams().width=950;

        storageReference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
            @Override
            public void onSuccess(Uri uri) {


                BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter.Builder(MainActivity.this).build();
                TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
                ExoPlayer exoPlayer = (SimpleExoPlayer) ExoPlayerFactory.newSimpleInstance(MainActivity.this);
                Uri video = Uri.parse(uri.toString());
                DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("video");
                ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
                MediaSource mediaSource = new ExtractorMediaSource(video,dataSourceFactory,extractorsFactory,null,null);
                playerView.setPlayer(exoPlayer);
                exoPlayer.prepare(mediaSource);
                exoPlayer.setPlayWhenReady(false);

            }
        });
