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))

Global av_fifo_grow (AVFifoBuffer *f, unsigned int additional_space)

use the new AVFifo-API with av_fifo_grow2(); note that unlike this function it adds to the allocated size, rather than to the used size

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.

Global av_get_channel_description (uint64_t channel)

use av_channel_description()

Global av_get_channel_layout (const char *name)

use av_channel_layout_describe()

Global av_get_channel_name (uint64_t channel)

use av_channel_layout_standard()

Global av_mallocz_array (size_t nmemb, size_t size) av_malloc_attrib

use av_calloc()

Global av_tempfile (const char *prefix, char **filename, int log_offset, void *log_ctx)

as fd numbers cannot be passed saftely between libs on some platforms

Global avcodec_get_frame_class (void)

This function should not be used.

Global AVCodecContext::channel_layout

use ch_layout

Global AVCodecContext::channels

use ch_layout.nb_channels

Global AVCodecContext::debug_mv

unused

Global AVCodecContext::request_channel_layout

use "downmix" codec private option

Global AVCodecContext::sub_text_format

unused

Global AVCodecContext::thread_safe_callbacks

the custom get_buffer2() callback should always be thread-safe. Thread-unsafe get_buffer2() implementations will be invalid starting with LIBAVCODEC_VERSION_MAJOR=60; in other words, libavcodec will behave as if this field was always set to 1. Callers that want to be forward compatible with future libavcodec versions should wrap access to this field in #if LIBAVCODEC_VERSION_MAJOR < 60

Global avfilter_pad_count (const AVFilterPad *pads)

Use avfilter_filter_pad_count() instead.

Global AVFrame::channel_layout

use ch_layout instead

Global AVFrame::channels

use ch_layout instead

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.
