ffmpeg | branch: master | Anton Khirnov <anton@khirnov.net> | Sun Jan 29 22:13:33 2023 +0100| [5c36f4ef8410008d508b9ca348441903a15a6f7c] | committer: Anton Khirnov lavu/opt: use AV_DICT_MULTIKEY in av_opt_set_dict2() If the dictionary provided on input contains multiple entries for an option (relevant for flags modifying the previous value with '+' or '-') and the option is not found in the target object, only the last entry would be returned to the caller. Pass AV_DICT_MULTIKEY to av_dict_set() to make sure all such entries are returned.
