在Media Encoder SDK 如何设置视频输出的分辨率
我这样设置怎么不行啊？
IWMEncProfile2* pProFile2;
IWMEncAudienceObj* pAudience;
long lCount;
long lVWith ;
long lVheight;
CString strResolution;
hr =CoCreateInstance( CLSID_WMEncProfile2,
NULL,
CLSCTX_INPROC_SERVER,
IID_IWMEncProfile2,
(void ** ) &pProFile2);
IFS( hr );
hr = pProFile2->LoadFromIWMProfile( pPro );
IFS( hr );
hr = pProFile2->put_VBRMode( WMENC_VIDEO, 0, WMENC_PVM_NONE );
hr = pProFile2->get_Audience( 0, &pAudience );
hr = pAudience->put_VideoWidth( 0, 640 );
hr = pAudience->put_VideoHeight( 0, 240 );
请指教．．．．．
