PFNKSDEFAULTFREE callback function

Description

An AVStream minidriver's AVStrMiniAllocatorFreeFrame routine frees the specified frame.

Parameters

Context [in]

Pointer to the allocator's context structure created in AVStrMiniInitializeAllocator.

Buffer [in]

Pointer to the frame to be freed.

Remarks

The minidriver specifies this routine's address in the Free member of its KSALLOCATOR_DISPATCH structure. The minidriver passes this structure to the class driver in KSPIN_DISPATCH.

AVStream calls AVStrMiniFree to free a frame, passing as parameters the context structure set in the initialization dispatch and a pointer to the frame to free.

For more information, see KS Allocators.
