IAMVideoControl::GetCurrentActualFrameRate (Windows Embedded CE 6.0)

  • Article

1/6/2010

This method retrieves the actual frame rate, expressed as a frame duration in 100-nanosecond units. USB (Universal Serial Bus) and IEEE 1394 cameras may provide lower frame rates than requested because of bandwidth availability. This is only available during video streaming.

Syntax

HRESULT GetCurrentActualFrameRate (
  IPin*     pPin,
  LONGLONG* ActualFrameRate
);

Parameters

  • pPin
    [in] A pointer to the IPin interface to retrieve the frame rate from.
  • ActualFrameRate
    [out] Pointer to a LONGLONG value that will contain the frame rate in terms of 100-nanosecond units.

Return Value

Returns an HRESULT value that depends on the implementation of the interface.

Remarks

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.
