<P> 類廠對(duì)象是用來生成Filter對(duì)象的，用的模板類定義了一個(gè)全局的模板類對(duì)象數(shù)組，一般格式如下：</P>
<P> <CODE>CFactoryTemplate g_Templates[1] =<BR>{<BR> {<BR> L"my
filter", // Name<BR> &CLSID_MYFilter, //
CLSID<BR> CMyFilter::CreateInstance, // Method to create an instance of
MyComponent<BR> NULL, // Initialization
function<BR> &sudInfTee // Set-up information (for
filters)<BR> }<BR>};<BR>int g_cTemplates = sizeof(g_Templates) /
sizeof(g_Templates[0]); </CODE>
<P> 4、關(guān)于你自己定義的Filter以及Pin的信息</P>
<P> 這些是一個(gè)全局的結(jié)構(gòu)變量，用于描述你的Filter和你定義的pin，在注冊(cè)Filter的時(shí)候會(huì)用到，如下：</P><CODE>AMOVIESETUP_FILTER
描述一個(gè)Filter<BR>AMOVIESETUP_PIN 描述pin<BR>AMOVIESETUP_MEDIATYPE 描述數(shù)據(jù)類型</CODE>
<P> 下面的代碼描述了一個(gè)Filter帶有一個(gè)output PIN：</P>
<P> <CODE>static const WCHAR g_wszName[] = L"Some
Filter";<BR>AMOVIESETUP_MEDIATYPE sudMediaTypes[] = {<BR> {
&MEDIATYPE_Video, &MEDIASUBTYPE_RGB24 },<BR> { &MEDIATYPE_Video,
&MEDIASUBTYPE_RGB32 },<BR>};<BR>AMOVIESETUP_PIN sudOutputPin =
{<BR> L"", // Obsolete, not used.<BR> FALSE, // Is this pin
rendered?<BR> TRUE, // Is it an output pin?<BR> FALSE, // Can the
filter create zero instances?<BR> FALSE, // Does the filter create multiple
instances?<BR> &GUID_NULL, // Obsolete.<BR> NULL, //
Obsolete.<BR> 2, // Number of media types.<BR> sudMediaTypes // Pointer
to media types.<BR>};<BR>AMOVIESETUP_FILTER sudFilterReg =
{<BR> &CLSID_SomeFilter, // Filter CLSID.<BR> g_wszName, // Filter
name.<BR> MERIT_NORMAL, // Merit.<BR> 1, // Number of pin
types.<BR> &sudOutputPin // Pointer to pin information.<BR>};</CODE>
<P> 最后如果你還是調(diào)試通不過，看看你是否包含了下面的頭文件：</P>
<P></P><CODE>#include <streams.h><BR>#include
<initguid.h><BR>#include <tchar.h><BR>#include
<stdio.h></CODE>
