void* AVFilterPic::priv

private data to be used by a custom free function

Definition at line 61 of file avfilter.h.

void(* AVFilterPic::free)(struct AVFilterPic *pic)

A pointer to the function to deallocate this image if the default function is not sufficient. This could, for example, add the memory back into a memory pool to be reused later without the overhead of reallocating it from scratch.
