Detailed Description
Implementation of a default memory allocator.
The default memory allocator uses the routine malloc from the standard C library, but decoder implementations are free to replace the default allocator with an algorithm that implements a better memory allocation policy.
See the discussion in the file documentation for allocator.h
Some memory allocation schemes may choose to ignore a request to free memory and subsequent calls to Alloc may reuse blocks that were previously allocated for decoding an earlier sample.
Memory allocation by the decoder follows a simple pattern. Blocks that are allocated during decoder initialization are used during the decoding of all samples in the video stream until the decoder is reinitialized, while a block that is allocated during decoding is always freed by the same routine that allocated the block and a block of the same size will be allocated and freed again by the same routine.
