Data Fields
void *(*	alloc_large )(size_t size)
	big buffers: decoders, readahead, caches (PSRAM)
void *(*	alloc_fast )(size_t size)
	small hot buffers (internal RAM)
void *(*	realloc_large )(void *ptr, size_t size)
	grows memory from either allocator
void(*	free )(void *ptr)
	frees memory from either allocator

Detailed Description

Memory.

On ESP32 the platform routes "large" allocations to PSRAM and "fast" allocations to internal RAM. On the host both map to malloc.
