在发布模式下崩溃，在调试模式下遇到错误

这是我关于堆栈溢出的第一个问题，所以请回答我。

我正在使用 libvlc 库 2.1.5win64 用于窗口 7 和 Qt 4.8.5、C++ 和 Cmake 2.8 来构建一个以 rtsp 协议从 VLC 服务器捕获流视频的项目。我非常严重地面临两个问题。

1：我的程序在发布模式下.exe文件膨胀，但是当我们打开（双击）此.exe文件时崩溃，而它在调试模式下正常工作。

2：我的程序在调试模式下也无法正常工作，当我打开.exe文件时，它显示一个小部件，但视频没有流式传输

它遇到错误

[0000000001c96b20] main input error: open of 'rtsp"//192.168.1.101:8554/' failed 
[0000000001bcce90] main input error: your input can't be opened
[0000000001bcce90] main input error: VLC is unable to open the MRL 'rtsp://192.168.1.101:8554/'. check the log for details.

请有人回答我的问题...

我还在为我的源代码提供 cmakelist......

如果可能的话，请编辑我的代码，因为我是Qt，Cmake，LibVlc的新手
