stdarg.h has been included in780d7897a9for ff_url_join(). This header became unnecessary when this function was moved into a separate file indf9f22d42b. libavutil/pixdesc.h has been included for av_get_pix_fmt_name() in603b8bc2a1and is unused since commit2fb7501938that removed the stuff belonging to FF_API_FORMAT_PARAMETERS. Notice that this file still uses AV_PIX_FMT_NONE and that therefore the header libavutil/pixfmt.h has been included (this header is included in pixdesc.h as well as also in libavutil/internal.h which is also included). libavutil/time_internal.h has been included for gmtime_r() in commit e7dd97b5d8cd6ea150446591f37a5946e8ab7cfb; it is unused since commitb72a7b96f8which basically moved the code making use of gmtime_r() to libavutil/dict.c to use in avpriv_dict_set_timestamp(). audiointerleave.h has been added inc26e58e32cbecause of ff_interleave_compare_dts() (at that time the muxing code was not split from utils.c yet); said function became static in commit101e1f6ff9, making this header redundant. metadata.h has been mostly included for what now resides in libavutil/dict.h. The stuff that now resides in metadata.h has only been used briefly: From commitsed7694d8cftod60a9f52eb. riff.h has been added in45da8124a0because riff.h once contained declarations for (ff_)codec_get_tag(). This was changed inbfe5454cd2. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
