Question

我正在尝试在Django上构建视频播放器。我正在使用MPEG-DASH自适应地传输视频文件。一开始我选择了一个示例视频。然后，使用ffmpeg命令，将视频编码为240p，360p，480p和720p视频。也有单独编码的音频。

然后，使用mp4box生成了.mpd文件。我已经读过mpd文件无法从本地文件系统运行，而需要托管在服务器上。我的破折号播放器设置如下：

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title>player</title>
    <script src="https://cdn.dashjs.org/latest/dash.all.min.js"></script>
    <style>
    video {
       width: 640px;
       height: 360px;
    }
</style>
  </head>
  <body>
    <div>
       <video data-dashjs-player autoplay src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd" controls></video>
   </div>
  </body>
</html>

src字段中的url是我用来测试播放器的随机清单文件。很好。

然后，在我的Django项目中，我创建了一个媒体文件夹，该文件夹存储通过表单（settings.py中包含的根）上传的媒体文件。我的问题是，我在哪里存储视频，音频和.mpd文件，以便可以使用模板文件夹中的html代码播放它们。我已经尝试在源文件中使用.mpd文件的媒体网址，但无法播放视频。

以下是生成的mpd文件以供参考：

哪里将.mpd文件存储在Django上，以便在破折号播放器上播放？
