convert heif/heic to jpg using gpac

I'm trying to convert HEIC to JPG using GPAC/MP4Box. I have been able to get small JPG "tiles" for a single HEIC file but I can't figure out how to get one large JPG.

Commands are like:

% MP4Box -dump-item 1:path=tile1.hevc iphonesample.heic
% ffmpeg -i tile1.hevc -frames:v 1 -q:v 1 -an tile1.jpg

Once you have all HEVC files extracted, create a text file

file file1.hevc

file file2.hevc

file file3.hevc

...

file file48.hevc

then run,

ffmpeg -f concat -i list.txt -vf tile=8x6 -vframes 1 -q:v 1 grid.jpg
