Safari is supposed to support animated AVIF images since version 16, but the ones I've tested perform very poorly, even on an M4 Mac Mini running Sequoia 15.1.1.
I believe Safari delegates decoding to the operating system itself, so this issue also happens in Live Preview in the finder, when I try to preview a file.
Sample file here: https://s3.us-west-2.amazonaws.com/cdn.paintera.org/test/sample.avif
322KB file, 5 seconds long, 12fps
This plays perfectly on Chrome on Mac OS, but is slow and laggy on Safari and Live Preview (it takes about 6.5 seconds to finish the 5 second video).
Does anyone know how to fix this or workaround this issue?
