Global av_fifo_freep (AVFifoBuffer **f)

use the AVFifo API with av_fifo_freep2()

Global av_fifo_generic_peek (AVFifoBuffer *f, void *dest, int buf_size, void(*func)(void *, void *, int))

use the new AVFifo-API with av_fifo_peek() when func == NULL, av_fifo_peek_to_cb() otherwise

Global av_fifo_generic_peek_at (AVFifoBuffer *f, void *dest, int offset, int buf_size, void(*func)(void *, void *, int))

use av_fifo_can_write() with the new AVFifo-API

Global av_fopen_utf8 (const char *path, const char *mode)

Avoid using it, as on Windows, the FILE* allocated by this function may be allocated with a different CRT than the caller who uses the FILE*. No replacement provided in public API.

File dict.h

AVDictionary is provided for compatibility with libav. It is both in implementation as well as API inefficient. It does not scale and is extremely slow with large dictionaries. It is recommended that new code uses our tree container from tree.c/h where applicable, which uses AVL trees to achieve O(log n) performance.
