ExoPlayer-奇怪的阿拉伯语/波斯语字幕格式

Question

我正在尝试创建一个带有字幕的视频播放器。除了一件事，一切都设置好了，工作正常。我的阿拉伯语字幕显示不正确。他们用符号之类的东西看起来很奇怪。。比如：

以下是我的ExoPlayer设置和子倾斜：

Uri srt = Uri.parse("http://download1651.mediafire.com/titdvyxje25g/j5wpodffdhn005r/Thor+3+.WEB+%28NoColored%29.srt");
    
    Handler mainHandler = new Handler();
    BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    TrackSelection.Factory videoTrackSelectionFactory =
            new AdaptiveTrackSelection.Factory(bandwidthMeter);
    TrackSelector trackSelector =
            new DefaultTrackSelector(videoTrackSelectionFactory);
    player =
            ExoPlayerFactory.newSimpleInstance(this, trackSelector);
    DefaultBandwidthMeter bandwidthMeter2 = new DefaultBandwidthMeter();
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
            Util.getUserAgent(this, "yourApplicationName"), bandwidthMeter2);
    Format textFormat = Format.createTextSampleFormat(null, MimeTypes.APPLICATION_SUBRIP,
            null, Format.NO_VALUE, Format.NO_VALUE, "ar", null, Format.OFFSET_SAMPLE_RELATIVE);
    MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory)
            .createMediaSource(Uri.parse(getVideoUri()));
    MediaSource textMediaSource = new SingleSampleMediaSource.Factory(dataSourceFactory)
            .createMediaSource(srt, textFormat, C.TIME_UNSET);
    MediaSource mediaSource = new MergingMediaSource(videoSource, textMediaSource);


    player.prepare(mediaSource);

有什么解决办法吗？

该文件的编码为windows-1256。您应该先将其更改为Unicode，然后才能正确地看到它。

BufferedReader reader = new BufferedReader(
        new InputStreamReader(new FileInputStream("arabic sub.srt"), "windows-1256")
    );
String line = null;
BufferedWriter writer = new BufferedWriter(
    new OutputStreamWriter(new FileOutputStream("new.srt"), "UTF-8")
);
while((line = reader.readLine())!= null){        
    writer.write(line);
    writer.write("\r\n");
}
writer.close();
