Actually, right now I'm thinking about whether cold pizza is still edible.
mjpeg streams are still popular in machine-vision use-cases. And you can be fairly certain your webcam has that codec built-in if the device was made in the past 15 years. Note most media/gpu hardware is now integrated into modern browsers. =)
Is hardware avif decoding done anywhere? The only example I can think of where this is done is HEIF on iOS devices, maybe.
Some cloud GPUs have jpeg decoding blocks for ingesting tons of images, but that'd not really the same thing.
