uint8_t* AVFilterPic::data[4]

enum PixelFormat AVFilterPic::format

colorspace

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.
