問題(Question)：
從camera 讀取畫面後轉成 AVI 寫入
實測試無法把影像存成AVI 程式會自動結束
如何同時把聲音寫入?
程式碼(Code)：(請善用置底文網頁, 記得排版)
hr = pGraph->AddFilter(pCap,L"Vid Capture Filter");
IBaseFilter *pMux = 0;
hr =
pBuild->SetOutputFileName(&MEDIASUBTYPE_Avi,L"c:\\video.avi",&pMux,NULL);
if( FAILED(hr) )
{
printf("ERROR - SetOutputFileName () failed \n");
return ;
}
hr =
pBuild->RenderStream(&PIN_CATEGORY_CAPTURE,&MEDIATYPE_Video,pCap,NULL,pMux);
if( FAILED(hr) )
{
printf("ERROR - RenderStream () failed \n");
return ;
}
IConfigAviMux *pConfigMux = NULL;
hr = pMux->QueryInterface(IID_IConfigAviMux, (void**)&pConfigMux );
if(SUCCEEDED(hr))
{
pConfigMux->Release();
}
//設定輸出camera 畫面
hr = pBuild->RenderStream(&PIN_CATEGORY_PREVIEW, &MEDIATYPE_Video, pCap,
NULL, NULL);
if(FAILED(hr))
{
printf("ERROR - RenderStream() failed.\n");
return;
}
printf("SUCCESS - RenderStream() succeeded.\n");
