vlcPlayer是一款免费开源的播放器项目，可以播放几乎所有的视频格式。
第一步：获取dll
安装vlcplayer视频播放器，在安装目录下面获取所需的dll。
dll文件夹：plugins
还有2个dll：libvlc.dll，libvlccore.dll
第二步：获取播放器对象基类VlcPlayerBase

第三步：写代码实现
string pluginPath = Environment.CurrentDirectory + "\\plugins\\"; //插件目录
player = new VlcPlayerBase(pluginPath);
player.SetRenderWindow((int)pnlVideo.Handle);//panel
player.LoadFile(videoName[]);//视频文件路径
设置音量：
int volume = this.player.GetVolume();
volume--;
if (volume <0) volume = 0;
this.player.SetVolume(volume);
还有播放状态设置：
this.player.Play();
this.player.Pause();
this.player.Stop();
其他设置：
int durationSecond = (int)this.player.Duration;
int playTimeSecond = (int)this.player.GetPlayTime();
this.player.SetPlayTime(this.tkbProgress.Value);
