BRAW SDK 1.1 : using GetClipProcessingAttributeList ?

Hello,

The 1.1 update to the Blackmagic RAW SDK doesn't contain any example of how to use some new functions the update brought. For example GetClipProcessingAttributeList : it seems that the third argument (/* [out] */ VARIANT *array) is not returning a list but a BSTR alone , see this code :

Code: Select all

VARIANT value;
unsigned int length = 0;
HRESULT res = constants->GetClipProcessingAttributeList(
         L"Blackmagic URSA Mini Pro 4.6K",
         blackmagicRawClipProcessingAttributeGamut, // BSTR according to the documentation
         &value,
         &length
      );
// now length = 7
// res = S_OK
// value.vt = 8 = VT_BSTR
// value.bstrVal = L"Blackmagic Design"
// unable to read memory value.pbstrVal...


Any idea ?

Thanks in avance

Hi, you want to pass an array, using your code as example:

Code: Select all

std::vector<VARIANT> value;
uint32_t length;

HRESULT res = constants->GetClipProcessingAttributeList(
         "Blackmagic URSA Mini Pro 4.6K",
         blackmagicRawClipProcessingAttributeGamut,
         &value,
         &length
      );
