Yes, this patch only supports still HEIC images that don't have alpha
and grids (tiles).

Tiles and Alpha support will be possible only after AVStreamGroup is
implemented. I will look into HEIC sequences in a follow-up.

I tested it from the files in
https://github.com/nokiatech/heif/tree/gh-pages/content/images. I am
not sure about HEVC licensing and if we are allowed to copy some of
those files in the ffmpeg fate server. Would generating a random image
with ffmpeg and encoding it as HEIC be good enough?
