  • pamvpSize
    [in, out] Pointer to an AMVPSIZE structure containing the desired width and height. The structure receives the final dimensions upon return.
  • pdwMaxPixelsPerSecond
    [out] Pointer to the retrieved maximum pixels per second rate.

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.

Value Description
E_FAIL Failure.
E_POINTER NULL pointer argument.
E_INVALIDARG Invalid argument.
NOERROR The maximum pixel rate was retrieved.


This method retrieves the maximum pixels per second rate expected for a given format and a given scaling factor. If the decoder does not support those scaling factors, then it returns the rate and the nearest scaling factors it supports.
