This sums up the situation
IANAL, and I know basically nothing about codec patents, but it might be
worth noting that there are a whole bunch of video coding techniques that
are presumably completely unnecessary for decoding video *stills*, i.e.
I-frames. Things like motion compensation are irrelevant if there's no
So it's at least slightly plausible that any patents in question wouldn't
apply to a heavily stripped down decoder that only implemented the parts of
the spec needed to decode HEIF.
