A reference counted buffer type. More...

#include <buffer_internal.h>

Data Fields

uint8_t * data

data described by this buffer

size_t size

size of data in bytes

atomic_uint refcount

number of existing AVBufferRef instances referring to this buffer

void(* free )(void *opaque, uint8_t *data)

a callback for freeing the data

void * opaque

an opaque pointer, to be used by the freeing callback

int flags

A combination of AV_BUFFER_FLAG_*.

int flags_internal

A combination of BUFFER_FLAG_*.

Detailed Description

A reference counted buffer type.

It is opaque and is meant to be used through references (AVBufferRef).
