CBaseAllocator.Free method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Free method releases all of the buffer memory. This method is called when the owning filter decommits the allocator, after the last media sample is released.
Syntax
virtual void Free() = 0;
Parameters
This method has no parameters.
Return value
This method does not return a value.
Remarks
After the Decommit method is called, the allocator calls this method when it releases the last media sample. The derived class must implement this method.
