主要是压缩用什么filter 啊? XviD 是处理视频的吧,音频怎么办呢,然后两路怎么合成写入文件,有mpeg4 mux 吗? 小弟新手,各位大侠不吝赐教啊,:)

修改Xvid源代码
把它去掉是直接的方式

楼上的兄弟,你在哪下的XviD Codec 呀,我装的这个每次编码总弹出一个"XviD Status"对话框

我是这样加到graph里的。
ICreateDevEnum *pSysDevEnum = NULL;
hr = CoCreateInstance(CLSID_SystemDeviceEnum, NULL, CLSCTX_INPROC_SERVER,
IID_ICreateDevEnum, (void **)&pSysDevEnum);
if (FAILED(hr))
return hr;
// Obtain a class enumerator for the video compressor category.
IEnumMoniker *pEnumCat = NULL;
hr = pSysDevEnum->CreateClassEnumerator(CLSID_VideoCompressorCategory, &pEnumCat, 0);
if (hr == S_OK)
{
// Enumerate the monikers.
IMoniker *pMoniker = NULL;
ULONG cFetched;
while(pEnumCat->Next(1, &pMoniker, &cFetched) == S_OK)
{
IPropertyBag *pPropBag;
hr = pMoniker->BindToStorage(0, 0, IID_IPropertyBag,
(void **)&pPropBag);
if (SUCCEEDED(hr))
{
// To retrieve the filter's friendly name, do the following:
VARIANT varName;
VariantInit(&varName);
hr = pPropBag->Read(L"FriendlyName", &varName, 0);
if (SUCCEEDED(hr))
{
if(COleVariant(varName) == COleVariant("XviD MPEG-4 Codec"))
{
hr = pMoniker->BindToObject(NULL, NULL, IID_IBaseFilter,
(void**)&m_pXvidvfw);
// Now add the filter to the graph.
hr = m_pGraph->AddFilter(m_pXvidvfw, L"XviD MPEG-4 Codec");
if (!SUCCEEDED(hr))
m_pXvidvfw->Release();
break;
}

}
VariantClear(&varName);

// To create an instance of the filter, do the following:
//Remember to release pFilter later.
pPropBag->Release();
}
pMoniker->Release();
}
pEnumCat->Release();
}
pSysDevEnum->Release();
