Global avcodec_get_context_defaults3 (AVCodecContext *s, const AVCodec *codec): This function should not be used, as closing and opening a codec context multiple time is not supported. A new codec context should be allocated for each new use.
Global avcodec_get_edge_width (void): CODEC_FLAG_EMU_EDGE is deprecated, so this function is no longer needed
Global avcodec_get_pix_fmt_loss (enum AVPixelFormat dst_pix_fmt, enum AVPixelFormat src_pix_fmt, int has_alpha): see av_get_pix_fmt_loss()

Global AVFrame::pkt_pts: use the pts field instead
Global AVFrame::reordered_opaque: in favor of pkt_pts
Global AVPacket::convergence_duration: Same as the duration field, but as int64_t. This was required for Matroska subtitles, whose duration values could overflow when the duration field was still an int.

Global CODEC_FLAG_NORMALIZE_AQP: use the flag "naq" in the "mpv_flags" private option of the mpegvideo encoders
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.
