typedef struct AVFifoBuffer AVFifoBuffer |
AVFifoBuffer* av_fifo_alloc | ( | unsigned int | size | ) |
Initialize an AVFifoBuffer.
size | of FIFO |
AVFifoBuffer* av_fifo_alloc_array | ( | size_t | nmemb, |
size_t | size | ||
) |
Initialize an AVFifoBuffer.
nmemb | number of elements |
size | size of the single element |
void av_fifo_drain | ( | AVFifoBuffer * | f, |
int | size | ||
) |
Read and discard the specified amount of data from an AVFifoBuffer.
f | AVFifoBuffer to read from |
size | amount of data to read in bytes |
void av_fifo_free | ( | AVFifoBuffer * | f | ) |
Free an AVFifoBuffer.
f | AVFifoBuffer to free |
void av_fifo_freep | ( | AVFifoBuffer ** | f | ) |
Free an AVFifoBuffer and reset pointer to NULL.
f | AVFifoBuffer to free |
int av_fifo_generic_peek | ( | AVFifoBuffer * | f, |
void * | dest, | ||
int | buf_size, | ||
void(*)(void *, void *, int) | func | ||
) |
Feed data from an AVFifoBuffer to a user-supplied callback. Similar as av_fifo_gereric_read but without discarding data.
f | AVFifoBuffer to read from |
buf_size | number of bytes to read |
func | generic read function |
dest | data destination |
int av_fifo_generic_peek_at | ( | AVFifoBuffer * | f, |
void * | dest, | ||
int | offset, | ||
int | buf_size, | ||
void(*)(void *, void *, int) | func | ||
) |
Feed data at specific position from an AVFifoBuffer to a user-supplied callback. Similar as av_fifo_gereric_read but without discarding data.
f | AVFifoBuffer to read from |
offset | offset from current read position |
buf_size | number of bytes to read |
func | generic read function |
dest | data destination |
int av_fifo_generic_read | ( | AVFifoBuffer * | f, |
void * | dest, | ||
int | buf_size, | ||
void(*)(void *, void *, int) | func | ||
) |
Feed data from an AVFifoBuffer to a user-supplied callback.
f | AVFifoBuffer to read from |
buf_size | number of bytes to read |
func | generic read function |
dest | data destination |
int av_fifo_generic_write | ( | AVFifoBuffer * | f, |
void * | src, | ||
int | size, | ||
int(*)(void *, void *, int) | func | ||
) |
Feed data from a user-supplied callback to an AVFifoBuffer.
f | AVFifoBuffer to write to |
src | data source; non-const since it may be used as a modifiable context by the function defined in func |
size | number of bytes to write |
func | generic write function; the first parameter is src, the second is dest_buf, the third is dest_buf_size. func must return the number of bytes written to dest_buf, or <= 0 to indicate no more data available to write. If func is NULL, src is interpreted as a simple byte array for source data. |
int av_fifo_grow | ( | AVFifoBuffer * | f, |
unsigned int | additional_space | ||
) |
Enlarge an AVFifoBuffer. In case of reallocation failure, the old FIFO is kept unchanged. The new fifo size may be larger than the requested size.
f | AVFifoBuffer to resize |
additional_space | the amount of space in bytes to allocate in addition to av_fifo_size() |
int av_fifo_realloc2 | ( | AVFifoBuffer * | f, |
unsigned int | size | ||
) |
Resize an AVFifoBuffer. In case of reallocation failure, the old FIFO is kept unchanged.
f | AVFifoBuffer to resize |
size | new AVFifoBuffer size in bytes |
void av_fifo_reset | ( | AVFifoBuffer * | f | ) |
Reset the AVFifoBuffer to the state right after av_fifo_alloc, in particular it is emptied.
f | AVFifoBuffer to reset |
int av_fifo_size | ( | const AVFifoBuffer * | f | ) |
Return the amount of data in bytes in the AVFifoBuffer, that is the amount of data you can read from it.
f | AVFifoBuffer to read from |
int av_fifo_space | ( | const AVFifoBuffer * | f | ) |
Return the amount of space in bytes in the AVFifoBuffer, that is the amount of data you can write into it.
f | AVFifoBuffer to write into |
