what we get is more x265 and more Closed source shit.
I would disagree that people want AV1, people want something that is compatible across a wide range of devices and uses, which is why MPEG-2 is still used in many places, and why H264 is still so popular.
HEVC is still a beast to work with, in terms of editing and hardware playback support is still not ubiquitous.
VP9 is completely open, with open source implementations and is very high quality, yet it hasn't taken over.
JPEG2000 came out in, wait for it, 2000, and it's still widely used as both an acquisition format, RED cameras capture in JPEG2000 natively and ProRes and DNxHD with third party add ons.

Maybe it hasn't taken over due to its slower encoding?

Originally posted by tildearrow View PostI agree. I feel it's mostly designed with hardware accelerators in mind, and some are inconsistent. I tried decoding HEVC video with my AMD card, and saw a few differences when compared to CPU decoding.
Anyway, what happens if decoders are allowed to produce a different output is that the differences between the expected output & actual output will accumulate between decoder refreshes, leading to some sort of creeping picture corruption.
Originally posted by tildearrow View PostApparently professionals prefer proprietary formats... I don't see the reason though...
Anyway, here's what wikipedia says about JPEG 2000:
JPEG 2000 is covered by patents, but the contributing companies and organizations agreed that licenses for its first part—the core coding system—can be obtained free of charge from all contributors.
...
However, the JPEG committee has acknowledged that undeclared submarine patents may still present a hazard
