Canon CR3 Fileformat
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:
