int av_buffer_make_writable(AVBufferRef **buf)
Create a writable reference from a given buffer reference, avoiding data copy if possible.
void av_buffer_unref(AVBufferRef **buf)
Free a given reference and automatically free the buffer if there are no more references to it...
ptrdiff_t const GLvoid * data
void av_buffer_default_free(void *opaque, uint8_t *data)
Default free callback, which calls av_free() on the buffer data.
AVBufferRef * av_buffer_create(uint8_t *data, int size, void(*free)(void *opaque, uint8_t *data), void *opaque, int flags)
Create an AVBuffer from an existing array.
int av_buffer_realloc(AVBufferRef **buf, int size)
Reallocate a given buffer.
int av_buffer_is_writable(const AVBufferRef *buf)
AVBufferRef * av_buffer_alloc(int size)
Allocate an AVBuffer of the given size using av_malloc().
uint8_t * data
The data buffer.
int av_buffer_get_ref_count(const AVBufferRef *buf)
AVBufferRef * av_buffer_allocz(int size)
Same as av_buffer_alloc(), except the returned buffer will be initialized to zero.
void * av_buffer_get_opaque(const AVBufferRef *buf)
void av_buffer_pool_uninit(AVBufferPool **pool)
Mark the pool as being available for freeing.
A reference counted buffer type.
int size
Size of data in bytes.
A reference to a data buffer.
AVBufferPool * av_buffer_pool_init(int size, AVBufferRef *(*alloc)(int size))
Allocate and initialize a buffer pool.
AVBufferRef * av_buffer_ref(AVBufferRef *buf)
Create a new reference to an AVBuffer.
AVBufferRef * av_buffer_pool_get(AVBufferPool *pool)
Allocate a new AVBuffer, reusing an old buffer from the pool when available.
AVBufferRef *(* alloc)(int size)
