The example shows how to access the mosaic filter that was inserted as the first filter to the play object in the Programmatically Inserting a Processor Filter tutorial.
Call the play object to retrieve the first selected video processor as follows:
IUnknown *pUnk;IltmmPlay_GetSubObject(pPlay, ltmmPlay_Object_SelVideoProcessor, &pUnk);
IUnknown *pUnk;pPlay->GetSubObject(ltmmPlay_Object_SelVideoProcessor, &pUnk);
Retrieve the mosaic interface as follows:
ILMVMosaic *pVMF;IUnknown_QueryInterface(pUnk, &IID_ILMVMosaic, (void**) &pVMF);IUnknown_Release(pUnk);
ILMVMosaic *pVMF;pUnk->QueryInterface(&IID_ILMVMosaic, (void**) &pVMF);pUnk->Release();
Access the mosaic filter. For example, set the mosaic filter effect area rectangle.
CROP_ATTRIBUTES CropAttrib;CropAttrib.lLeft = 0;CropAttrib.lTop = 0;CropAttrib.lRight = 0;CropAttrib.lBottom = 0;CropAttrib.bEnabled = TRUE;ILMVMosaic_SetCropAttributes(pVMF, CropAttrib);IUnknown_Release(pVMF);
CROP_ATTRIBUTES CropAttrib;CropAttrib.lLeft = 0;CropAttrib.lTop = 0;CropAttrib.lRight = 0;CropAttrib.lBottom = 0;CropAttrib.bEnabled = TRUE;pVMF->SetCropAttributes(CropAttrib);pVMF->Release();
Clean up the play object.
IUnknown_Release(pPlay); pPlay->Release(); Help Collections
