Have you tried libheif? According to https://github.com/joedrago/avif/issues/11, it's a bit faster. Probably will need CPU/GPU chips that can accelerate the codecs more efficiently before the encode times really start coming down.

Recent notes are all about HEIF (~= iOS HEIC). It seems alarming to me that so many devices (Canon and iPhone at least) are putting out patent-encumbered HEIF/HEIC files while the available decoders are so incredibly slow. Last I looked, libHEIF is >50x slower than the built-in iOS decoders, which makes the format hundreds of times slower to decode than JPEG. With JPEG, the differences between free decoders and the "best" ones has been 2-3x in speed, but 50x slower is a huge cost that makes these formats unworkable for a whole lot of things, like most webservers. Does anyone know if things are getting better here? As an example, here are some 2019 benchmarks of Apple's HEIC decoder vs. libHEIF: https://github.com/joedrago/avif/issues/11
