FFmpeg accepts such streams as input, other programs may fail.

Hi
FFmpeg doesn't have ability to create avif image files (yet).
I have used FFmpeg to re-size png files then convert them with cavif program.
(Releases of cavif are here ---> https://github.com/kornelski/cavif-rs/releases)
Like this...
ffmpeg -i infile.png -vf scale="424:-1" temp.png; cavif
