VLC播放器

为了将多个视频放在一个窗口，最开始想用的是windows media player ，6个视频，把整个电脑卡得不动了（显卡太弱，是多输出口的，没法换），于是又想把视频压缩成一个，网上的大部分软件要收费，还是研究播放，就弄了VLC。

代码网上基本都一样的，但我调试了很久才走通。

主要是在调用，以及库的问题上，总结成3点，

一、关于库的问题，不要纠结，直接在网上搜索VLC media player 下载，国内站的也可以，(官网有可能要FQ)

安装后，可以看到三个需要的，plugins目录 ，libvlc.dll，libvlccore.dll ，放到你的debug目录

二、关于调用

string p = System.Environment.CurrentDirectory + "\\plugins\\";
VlcPlayer v = new VlcPlayer(p);
v.SetRenderWindow(pictureBox1.Handle.ToInt32());
v.PlayFile(@"1.mp4");

类是下面代码封装好的，大概就是这样

三、如果出现其它一些状况，请新建一个工程，不要在原工程上纠结。
