static AVBufferRef * | buffer_create (AVBuffer *buf, uint8_t *data, size_t size, void(*free)(void *opaque, uint8_t *data), void *opaque, int flags) |
AVBufferRef * | av_buffer_create (uint8_t *data, size_t size, void(*free)(void *opaque, uint8_t *data), void *opaque, int flags) |
Create an AVBuffer from an existing array. More... | |
void | av_buffer_default_free (void *opaque, uint8_t *data) |
Default free callback, which calls av_free() on the buffer data. More... | |
AVBufferRef * | av_buffer_alloc (size_t size) |
Allocate an AVBuffer of the given size using av_malloc(). More... | |
AVBufferRef * | av_buffer_allocz (size_t size) |
Same as av_buffer_alloc(), except the returned buffer will be initialized to zero. More... | |
AVBufferRef * | av_buffer_ref (const AVBufferRef *buf) |
Create a new reference to an AVBuffer. More... | |
static void | buffer_replace (AVBufferRef **dst, AVBufferRef **src) |
void | av_buffer_unref (AVBufferRef **buf) |
Free a given reference and automatically free the buffer if there are no more references to it. More... | |
int | av_buffer_is_writable (const AVBufferRef *buf) |
void * | av_buffer_get_opaque (const AVBufferRef *buf) |
int | av_buffer_get_ref_count (const AVBufferRef *buf) |
int | av_buffer_make_writable (AVBufferRef **pbuf) |
Create a writable reference from a given buffer reference, avoiding data copy if possible. More... | |
int | av_buffer_realloc (AVBufferRef **pbuf, size_t size) |
Reallocate a given buffer. More... | |
int | av_buffer_replace (AVBufferRef **pdst, const AVBufferRef *src) |
Ensure dst refers to the same data as src. More... | |
AVBufferPool * | av_buffer_pool_init2 (size_t size, void *opaque, AVBufferRef *(*alloc)(void *opaque, size_t size), void(*pool_free)(void *opaque)) |
Allocate and initialize a buffer pool with a more complex allocator. More... | |
AVBufferPool * | av_buffer_pool_init (size_t size, AVBufferRef *(*alloc)(size_t size)) |
Allocate and initialize a buffer pool. More... | |
static void | buffer_pool_flush (AVBufferPool *pool) |
static void | buffer_pool_free (AVBufferPool *pool) |
void | av_buffer_pool_uninit (AVBufferPool **ppool) |
Mark the pool as being available for freeing. More... | |
static void | pool_release_buffer (void *opaque, uint8_t *data) |
static AVBufferRef * | pool_alloc_buffer (AVBufferPool *pool) |
AVBufferRef * | av_buffer_pool_get (AVBufferPool *pool) |
Allocate a new AVBuffer, reusing an old buffer from the pool when available. More... | |
void * | av_buffer_pool_buffer_get_opaque (const AVBufferRef *ref) |
Query the original opaque parameter of an allocated buffer in the pool. More... | |
