- Global CODEC_FLAG_GMC
- use the "gmc" private option of the libxvid encoder
- Global CODEC_FLAG_INPUT_PRESERVED
- passing reference-counted frames to the encoders replaces this flag

- 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.
