CBaseAllocator::ReleaseBuffer (Compact 2013)

  • Article

3/26/2014

Releases the object back to the list of free objects.

Syntax

HRESULT ReleaseBuffer(
  IMediaSample* pSample
);

Parameters

  • pSample
    Pointer to the IMediaSample interface of the media sample object.

Return Value

None.

Remarks

This member function implements the IMemAllocator::ReleaseBuffer method.

It adds the sample to the free list (represented by m_lFree) and calls CBaseAllocator::NotifySample to notify any blocked thread waiting for a free sample.

If there is a pending CBaseAllocator::Decommit call (indicated by m_bDecommitInProgress), the pure virtual CBaseAllocator::Free member function is called to decommit memory when the last buffer is placed on the free list.

Requirements

dshow.h,
