AVI API

打开AVI文件，并且返回地址，主要获得打开的次数，但是不释放，释放要用到AVIFileRelease;

STDAPI AVIFileOpen(   PAVIFILE *ppfile,   //缓冲区，接受IAVIFILE指针   LPCTSTR  szFile,  //要打开的文件名   UINT     mode,    //打开文件的权限模式，磨人的是OF_READ；   CLSID    pclsidHandler   //NULL,默认为从注册表中获取定义的Handler指针);

Returns zero if successful or an error otherwise

The AVIFileCreateStream function creates a new stream in an existing file and creates an interface to the new stream.

STDAPI AVIFileCreateStream(   PAVIFILE       pfile,//要打开的文件   PAVISTREAM     *ppavi,    //新的接口流的指针   AVISTREAMINFO  *psi    //包含新数据流的结构体指针);

Returns zero if successful or an error otherwise

设置流的格式和指定的位置

STDAPI AVIStreamSetFormat(   PAVISTREAM pavi,    //要打开的流   LONG       lPos,  //要接受这个格式流的位置   LPVOID     lpFormat,  //新的流的结构体指针   LONG       cbFormat   //size, in bytes, of the block of memory referenced by lpFormat);

The AVIStreamWrite function writes data to a stream.

STDAPI AVIStreamWrite(   PAVISTREAM pavi,     //Handle to an open stream.   LONG       lStart,  //First sample to write   LONG       lSamples,  //Number of samples to write.   LPVOID     lpBuffer,   //Pointer to a buffer containing the data to write   LONG       cbBuffer,  //Size of the buffer referenced by lpBuffer.   DWORD      dwFlags,   LONG       *plSampWritten,  //Pointer to a buffer that receives the number of samples written. This can be set to NULL.   LONG       *plBytesWritten  //Pointer to a buffer that receives the number of bytes written. This can be set to NULL.);

Returns zero if successful or an error otherwise.
