The GetVideoAcceleratorGUIDs method retrieves a list of the GUIDs for the video accelerator formats accepted.
Syntax
HRESULT GetVideoAcceleratorGUIDs(
LPDWORD pdwNumGuidsSupported,
LPGUID pGuidsSupported
);
Parameters
pdwNumGuidsSupported
[in] [out] If pGuidsSupported is NULL, pdwNumGuidsSupported returns with the number of video accelerator format GUIDs supported. Otherwise, this parameter is a pointer to the maximum number of GUIDs to return in pGuidsSupported. If fewer than this number are supported, pdwNumGuidsSupported is updated to be the number of GUIDs actually returned.
pGuidsSupported
[in] [out] If this parameter is not NULL, the GUIDs supported are returned in this array, whose size in bytes is at least sizeof(GUID) * (*pdwNumGuidsSupported).
Return Values
Returns an HRESULT value that depends on the implementation of the interface. HRESULT can include one of the following standard constants, or other values not listed.
| Return code | Description |
| E_FAIL | Failure. |
| E_INVALIDARG | Argument is invalid. |
| E_NOTIMPL | Method is not supported. |
| E_POINTER | Null pointer argument. |
