如何通过 NPAPI 插件读取音乐文件并使用
我正在考虑从硬盘读取 MP3 文件并在浏览器中播放它。我知道一种方法 - 从<获取文件对象列表code> 标签，然后获取其对象 URL 并将其分配给 的 src。然而，这种技术也有一些缺点（其中之一，必须在每次页面刷新时重复）。
因此，我正在探索是否可以使用 NPAPI 插件从 HDD 读取音乐文件，然后以某种方式将其提供给 元素。但是，我不知道如何将图块的二进制内容转换为 javascript 可以使用的 File 对象。有什么建议吗？
I am playing with the idea of reading an MP3 file from the hard drive and playing it in the browser. I know one way of doing it - get list of File objects from <input> tag, then get their object URL and assign it to src of <audio>. However there are some drawbacks of this technique (for one, it has to be repeated on every page refresh).
Therefore I am exploring if I can use an NPAPI plugin to read the music file from the HDD and then give it to <audio> element somehow. However, I can't figure out how to convert the binary contents of the tile into a File object that javascript can use. Any suggestions?

我能想到的唯一选择是使用 data: url。我不确定音频标签是否支持这些，但 img 标签肯定支持它们。
顺便说一句，您知道 NPAPI 插件必须先通过对象标记注入页面，然后才能执行任何操作，对吧？确保您知道扩展和插件之间的区别，因为您所说的听起来更像是扩展问题。
另请查看 FireBreath；如果您决定使用 NPAPI 插件，那将大大简化您的生活。
The only option I can think of would be to use a data: url. I don't know for sure if these are supported in audio tags or not, but they are definitely supported in img tags.
BTW, you are aware that a NPAPI plugin has to be injected into the page in an object tag before it does anything, right? Make sure you know the difference between an extension and a plugin, because what you're talking about sounds more like an extension problem.
Also take a look at FireBreath; if you do decide to use a NPAPI plugin, that'll simplify your life a lot.
