While the basic idea of using HVEC for still image compression is good, I'm somewhat concerned on how complex the whole format, especially the container, for HEIF is. It is kinda cute and from one viewpoint pragmatic to reuse existing container format, but I'm afraid the flexibility might have unforeseen and undesirable side-effects. And of course there is the problem of different implementations supporting different subsets and extensions of the format.

They've already specified three different codec mappings - JPEG, AVC, and HEVC - so to open all HEIF files, you presumably need to implement all of the decoders.

Worse, there is a financial incentive to implement only a subset of the decoders - HEVC is more expensive than AVC which is more expensive than JPEG. Even things like 4:4:4 color are more expensive than 4:2:0 color for HEVC.

If PSD's have shown us anything: it's that complexity of the container doesn't matter to adoption, software support does.

It's a standard format, it's faster than the competition, it has just as good (or better) quality vs compression metrics...

... all it needs is support and it'll take off. Apple is a good start for that.

like usb-c and thunderbolt compatibility, I am worried there will be a lot of confusion and what works with what. Less in the area of devices that attach to your hw direction, but more when it comes to consumer devices with HW decoder support and getting these formats to display.
