我想在基于osmf的grind播放器上显示字幕。我做了以下事情

Question

我从（https://github.com/kutu/GrindPlayer）下载了grind player的源代码，然后按照该页面上给出的步骤操作。在我安装nginx并创建一个html页面以运行Grind播放器之后。来自grind player site（http://osmfhls.kutu.ru/docs/grind/#embed）我使用swfobject在html页面中嵌入了grind player。现在播放器被添加到我的页面，我能够在研磨播放器中运行视频，但问题是我不知道如何添加.srt文件以在grind中运行。作为我的html页面的以下代码的参考，我添加了'subtitle'变量并将其传递给变量'parameter'，该参数在swfobject中传递。请指导我哪里出错了？

        // Collect query parameters in an object that we can
        // forward to SWFObject:
       var subtitles = JSON.stringify({
    subtitles: [
        {
              src: "Closedcaption_atsc_rollup.srt"   // url to .srt file
            , label: "English"          // label for subtitles, will show in menu
            , language:"en"             // optional
        }

    ]

    // optinal, configuration to display subtitles
    // all properties by default, you can change only what you need
    , config: {
        // fontSize, in percentage of available width
        // for GrindPlayer available width for subtitles is 70% of player width
        // ex: if player width is 1280px, then real fontSize will be
        // Math.floor(1280 * 0.7 * 0.035) = 31
         fontSize: 0.035
        , minFontSize: 20
        , maxFontSize: 36
        , textColor: 0xDFDFDF
        , bgColor: 0x101010
        , bgAlpha: 0.8
    }
});

            var parameterNames = pqs.params(false);
