主管叫我看tcpmp播放器，求求你帮我，下面这句代码看了半年了555555 [复制链接]

主管叫我看tcpmp播放器，找出解码代码的接口！！
该如何去找关于音视频解码部分接口呢？

它是由14个项目组成的，其中主工程是一个叫player的，里面代码如下：

#include "../common/common.h"

#else

#endif

// don't want to use common.dll, but don't want to collide with DLL import function either
#define tcscpy_s _tcscpy_s

#if !defined(NO_PLUGINS) || defined(NDEBUG)
static void tcscpy_s(tchar_t* Out,int OutLen,const tchar_t* In)

}
}
#endif

从TCPMP的结构组成下手。

wzl999

把每个功能看成一个窗体类的对象，在窗体上贴图画图实现点击功能并加入TCPMP的实际对照功能即可，这个只是简单的界面制作了。个人感觉TCPMP的难点还是在他的解码上。还有如何使用所带的库，如何使用能让播放的效果更好，整个播放器运行的更流畅。也是个需要研究的东西。。
