如何从隔离存储中打开媒体播放器WebVTT字幕
我有mp4+vtt字幕视频播放器项目在Wp8 c#上。我来看看Microsoft.PlayerFramework.MediaPlayer和WebVTTPlugin，它们的工作原理是完美的：https://playerframework.codeplex.com/wikipage?title=Closed%20Captions%3a%20WebVTT im使用了这段代码，并且工作得很完美。但我运气不好，我的项目.vtt标题文件有"，“十进制分隔符，这意味着我的应用程序，我需要下载副标题，并替换所有"，”。并且保存独立存储，我处理它，但我不能设置标题源为隔离存储，因为隔离存储没有uri。我知道我说得不好，我举个例子说：

我在Windows UWP中也遇到了同样的问题。player.Source允许绝对本地URI，但webvtt插件不允许。
最后，我找到了如何让它发挥作用：
using System.IO;
var caption = new Caption
{
Description = "whatever",
Source = new Uri(Path.Combine("ms-appdata:///Local/", "test.vtt"))
};
Player.AvailableCaptions.Add(caption);
Player.SelectedCaption = Player.AvailableCaptions.FirstOrDefault();Stack Overflow用户

不确定这是否有效，但是在这篇文章中，您可以尝试一下
string fullpath = "";
using (IsolatedStorageFile kayitliDepo = IsolatedStorageFile.GetUserStoreForApplication())
{
IsolatedStorageFileStream stream = kayitliDepo.OpenFile("altyazi.vtt", FileMode.Open,FileAccess.Read);
fullpath = stream.Name;
}
caption.Source = new Uri(Name,Urikind.Absolute); // url points to sample.vtt file
caption.Description = "Türkçe";
player.AvailableCaptions.Add(caption);
player.SelectedCaption = player.AvailableCaptions.FirstOrDefault();https://stackoverflow.com/questions/27769778
