Keeps the existing
heif_check_filetype
behaviour since that is public API. Adds a new function to check both the major version and the compatible_brands list. Switches the heif-convert example to use that new function.I have put an arbitrary 512 byte limit on how long we expect the
ftyp
box could be. That seems reasonable, but could be higher or lower.The goal of this is to support files that are both video and images (sharing data), where the major_brand is something like
mp41
butheic
is listed in thecompatible_brands[]
.
