应用场景
1. 播放 海康 或者 大华 监控的 rtsp 实时视频流。
2. 有跨多个系统平台的视频播放需求。
准备材料
1. vlcj程序包，下载地址：
2. vlc软件，下载地址：
3. rtsp视频流：海康或者大华的摄像头账号，并设置rtsp视频流为开启状态。
操作步骤（以windows系统为例）
1. 下载vlc软件；
2. 安装vlc-3.0.16-win32.exe文件到系统中，安装路径为C:\Program Files\VideoLAN\VLC；
3. 下载vlcj程序包；
4. 复制程序包中的jar包到Java项目中，将jar包添加到项目运行环境中。
5. 编写播放器实现程序；
程序实现步骤
第一步，开启vlcj的自动发现本地库。
第二步，指定加载VLC的路径。
第三步，根据摄像头参数配置，拼装rtsp协议请求字符串。
第四步，创建播放窗体。
第五步，获取vlcj的播放器，将rstp参数传入播放器，调用播放方法。
