A sample: 636kb, 9sec, 320x240@15fps

Aves plays that one in ~11s instead of ~9s.

I also noticed that some webp loop and some don't. Not sure where the responsibility lies, image or player.

Edit: added some Flutter issues with multi-frame decoding.

Speed issues:

Rendering issues:

Should not worry about it. Webp sets loop times itself. Can be one time, can be several times, can be endless.
