Question

我正在尝试使用VLC媒体播放器流式传输在线视频。但是我收到的URL是随机的，因此该URL需要链接到VLC媒体播放器在线流。是否有任何API可以播放随机在线视频？

对我正在构建的项目有一点了解...

我有一台将从服务器接收URL并将在屏幕上播放的设备。
我以前是通过网络浏览器播放它的。但是这一次我希望它使用媒体播放器来实现。因此，我的问题是，是否有用于VLC媒体播放器的API可以用于流传输在线视频？

***顺便说一句，我正在使用python编写脚本。

Answer 1

如果该URL指向流/视频文件，则可以像其他任何操作一样直接在VLC中打开它。如果是HTML文档，则需要提取实际流的URL。

正如wizzwizz4所说，vlc.py程序可在https://wiki.videolan.org/Python_bindings处使用，以及wxpython，pyQt和pyGtk的示例代码

这是从命令行运行的大致代码，为您提供一个开始
