Hi,

i try to use the rotation filter, but when i use GetAttributs or SetAttribute function i have exeption or happen nothing.

Something other, when i try to read the settings, i see that in my structure not have a changes after GetAtr... function, but if i put the GetAtr... function after the structure inicialization, again i have exeption.

   long nIndex;
        ILMVRotate* LMVRotate;
         ROTATION_ATTRIBUTES rot_atrr;
        BSTR bstr;
//The string below is retrieved from the Filters List utility

       bstr = SysAllocString(L"@device:sw:{E526D606-22E7-494C-B81E-AC0A94BFE603}\\{E2B7DCDB-38C5-11D5-91F6-00104BDB8FF9}");
        nIndex = ltmmPlayCtrl1->VideoProcessors->Find(bstr);
        ltmmPlayCtrl1->SelectedVideoProcessors->Add(ltmmPlayCtrl1->VideoProcessors->Item (nIndex),0);
// Getting the the Emboss object
        LMVRotate = (ILMVRotate*)ltmmPlayCtrl1->GetSubObject((ltmmPlay_Object_SelVideoProcessor)+0);

// Fill our options
LMVRotate->GetRotationAttributes(&rot_atrr);

       rot_atrr.lRotationAngle=90;
        rot_atrr.bReverse=0;
        rot_atrr.bFlip=0;
        rot_atrr.bAutoStop=0;
        rot_atrr.lDRotationAngle=0;
        rot_atrr.bDReverse=0;
        rot_atrr.bDFlip=0;

// Set our options

LMVRotate->SetRotationAttributes(rot_atrr);
}

this is the events on filter button click. Somebody can help me? I am not sure that all is correct, i am a embedded engineer but now must made soft for PC, and want to buy component like this but first i want to test it .. but can't do this :(

p.s. i use the BCB6.0

Here's modified code:
void __fastcall TForm1::Button1Click(TObject *Sender)
{
   long nIndex;
   ILMVRotate* LMVRotate;
   ROTATION_ATTRIBUTES rot_atrr;
   BSTR bstr;
   //The string below is retrieved from the Filters List utility

   bstr = SysAllocString(L"@device:sw:{E526D606-22E7-494C-B81E-AC0A94BFE603}\\{E2B7DCDB-38C5-11D5-91F6-00104BDB8FF9}");
   nIndex = ltmmPlayCtrl1->VideoProcessors->Find(bstr);
   ltmmPlayCtrl1->SelectedVideoProcessors->Add(ltmmPlayCtrl1->VideoProcessors->Item (nIndex),0);
   // Getting the the Rotate object
   LPUNKNOWN pRotate = ltmmPlayCtrl1->GetSubObject((ltmmPlay_Object_SelVideoProcessor)+0);
   pRotate->QueryInterface(IID_ILMVRotate, (void **)&LMVRotate);
   pRotate->Release();

   // Fill our options
   LMVRotate->GetRotationAttributes(&rot_atrr);

   rot_atrr.lRotationAngle=90;
   rot_atrr.bReverse=0;
   rot_atrr.bFlip=0;
   rot_atrr.bAutoStop=0;
   rot_atrr.lDRotationAngle=0;
   rot_atrr.bDReverse=0;
   rot_atrr.bDFlip=0;

   // Set our options

   LMVRotate->SetRotationAttributes(rot_atrr);
   LMVRotate->Release();
}
