网易云从集成到多人视频会议（3）～中间的坑～～

本地视频

远程视频

这也是坑。。。
以一般人的思维，创建完会议室，然后加入房间，就跳转到视频页面，，显示本地自己的视频图像，，然后有人加进来的话再把对方的视频图像显示出来。
然而。。。不能这么做。就是在这里我卡了两天。。。。。。。真想打人。

创建加入会议房间必须在同一个页面完成，否则会出现本地视频代理方法不走。。然后你就获取不到本地流，显示不出来。。。

首先需要

           #import "NTESGLView.h"

这个东西（ijkl)这也是坑啊。。。倒入的时候报错。。相对路径和绝对路径的错
解决方法就是直接把相对路径去掉
#include "ijksdl_vout.h" 这样子。 就可以了。
