C++ 在视频结束或调用libvlc_media_player_stop后退出程序

我使用vlc-3.0.0将视频帧读入内存。问题是，当我调用libvlc_media_player_stop函数或它到达视频末尾时，程序会退出。我使用的是windows 7和Visual Studio 2012。也使用夜间构建来测试

以下是我的资料来源：

{

核心流输出调试：使用sout chain=`transcode{vcodec=I420，acodec=s16l}:smem{video prerender callback=18236016，video postreder callback=18235968，audio prerender callback=0，audio postreder callback=0，audio data=0，video data=0，time sync}，'
核心流输出调试：流=`smem'
核心流输出调试：寻找与“smem”匹配的源流模块：22个候选
核心流输出调试：设置配置选项：sout smem视频预渲染回调到18236016
核心流输出调试：设置配置选项：sout smem video postrender回调至18235968
core stream out调试：设置配置选项：sout smem音频预渲染回调到0
core stream out调试：设置配置选项：sout smem audio postrender回调为0
core stream out调试：设置配置选项：将smem音频数据设置为0
core stream out调试：设置配置选项：将smem视频数据设置为0
核心流输出调试：设置配置选项：sout smem时间同步到（null）
核心流输出调试：使用sout流模块“smem”
核心流输出调试：流=`transcode'
core stream out调试：查找与“transcode”匹配的源流模块：22 candid
