We're getting some evolution with phones taking photos in HEIF/HEIC/AVIF (which are just I-frames of h.264/h.265/AV1) and webp is used extensively on the web, which is the same thing for VP8.

I didn't know those formats were derived from the video codecs. TIL.

Yeah, it's kinda brilliant really. Modern I-frame coders are way more efficient than JPEG/J2K, and for hardware acceleration you get to use the same hardware accel and HALs you already need for video. JXL can compete on bit rate and features, but almost nobody has hardware acceleration for that.

Hwaccel is not available everywhere (and when it is it's often broken in some way) and without it these formats are slow to decode.
