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.

Global FF_LEVEL_UNKNOWN

The following define is deprecated; use AV_LEVEL_UNKOWN in defs.h instead.

Global FF_PROFILE_UNKNOWN

The following defines are deprecated; use AV_PROFILE_* in defs.h instead.
