CMediaSample::m_pAllocator

Pointer to the allocator that created this sample.

Syntax

  CBaseAllocator *m_pAllocator;

Remarks

Although the sample keeps a pointer to the allocator, it does not hold a reference count. Instead, the allocator increments its own reference count in the IMemAllocator::GetBuffer method, and releases itself in the IMemAllocator::ReleaseBuffer method. This guarantees that the allocator will be available as long as another object is using the sample.

Requirements

**  Header:** Declared in Amfilter.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
