by a user application

That makes the concat demuxer usable with MPEG-PS streams,
even when the streams in the different parts are detected
in different order.

ff_make_absolute_url() recognizes the "://" pattern usual
in HTTP-like protocols, but consider relative URLs starting
with just the protocol name or using the comma syntax for
options.

security concerns, as it allows a possibly hostile file to
access any file on the system. Guessing the format based on
the file name extension does not allow to enable the safe
mode designed to avoid it.

Use av_realloc instead of av_realloc_f to keep the original
