VLC播放器
最近在做WPF项目,需要做个本地的离线播放器,基本网上常用的有两种播放器,一种是 MediaElement方式的播放器,另一种就是Vlc的播放器,那么话不多说直接上代码!
1.先将Vlc播放器下载到本地进行安装,(官网地址:https://www.videolan.org/vlc/index.zh.html),注意下载是64位的,还是32位的,由于我的工程项目是x86的,所以我下的32位的
2.将安装后的路径(C:\Program Files (x86)\VideoLAN)下的VLC文件夹整体拷贝到项目的根目录下(\bin\x86\Debug)
3.然后在项目的NuGet管理包中安装需要用到的三个包:Vlc.DotNet.Core,Vlc.DotNet.Core.Interops,Vlc.DotNet.Wpf
4,介绍一下常用的API和Event
//暂停 this.vlcControl.SourceProvider.MediaPlayer.Pause();
//播放 this.vlcControl.SourceProvider.MediaPlayer.Play();
//音量控制 this.vlcControl.SourceProvider.MediaPlayer.Audio.Volume = 100;
//倍数控制 this.vlcControl.SourceProvider.MediaPlayer.Rate = 1.5f;
//视频长度 单位:ms var len = this.vlcControl.SourceProvider.MediaPlayer.Length;
//全屏 this.vlcControl.SourceProvider.MediaPlayer.Video.FullScreen = true;
//进度变化事件 this.vlcControl.SourceProvider.MediaPlayer.PositionChanged += MediaPlayer_PositionChanged;
5.上实例环节,鼓掌
