Use av_pix_fmt_get_chroma_sub_sample

Член 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.

Член avcodec_get_pix_fmt_loss (enum AVPixelFormat dst_pix_fmt, enum AVPixelFormat src_pix_fmt, int has_alpha)

Файл 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.
