“Access Advance and Avanci have published rates for a pool asserting content royalties across AVC, HEVC, VP9, VVC, and AV1 that could push major platforms toward nine-figure annual exposure.”

Yes, they've made claims on AV1, claims that have never been tested in court.
You need to understand that these are parasitic businesses. They didn't develop AV1. They didn't contribute to AV1. But they will make any claim they think they can get away with.
Show me the court case they've won that validates their claims on AV1.

AV1 was created by a consortium of some of the biggest tech companies in the world, and "all technology was vetted in a rigorous patent review process before being integrated into the final spec."[0]
On the other side, you've got patent trolls who are upset that their shitty business model is coming to an end. They're just being loud as they're losing.
From what I can find, seems opus only supports audio. ogg also has a video format (ogv), odd it is suggested ogg was superseded by opus. Maybe I am missing something ?
Ogg is the container, Vorbis is the audio codec, and colloquially people just called Vorbis-encoded audio "ogg" because of the ogg container.
Vorbis was hit-or-miss. In some cases it did better on same or lower bitrate than MP3 encoded by LAME, in some cases worse. It also suffered an entirely new category of "chirpy/tweety" artefacts similar to what MP3 exhibits at very low bitrates, but with Vorbis they showed up even at nominal bitrates during certain complex spectral patterns. I was a vocal propononent of Vorbis back when it surfaced, but soon changed stance when realizing how unreliable it was quality-wise.

I would bet that the primary reason wasn't the container format, which nobody really cares about and most users wouldn't have been aware of, but rather the fact that the file extension was '.ogg'.

AV1 / Opus where we can. But H264 is far better supported. For example, Safari doesn't include a software AV1 decoder. So AV1 videos only work in safari on M3 or later laptops, and iPhone 15 or later phones.
Safari, or better, macOS and iOS include a software AV1 decoder (libdav1d), but it's used only to decode avif, and to generate file previews in Finder.

Dolby just sued Snapchat over patents for using AV1:
> You can comfortably play AV1 video in software on your phone
Maybe for about 15 minutes before your battery is drained to 20%. I'm not aware of any software video decoder at all that won't unacceptably heat up your phone and kill your battery.

Why say maybe? Why not simply try it for yourself?
petcat•19m ago
I don't need to try it myself to know that software video decoding on the CPU is not a viable solution on mobile phones.
daneel_w•14m ago
You really are underestimating just how far e.g. Apple's mobile CPUs have come in terms of raw performance and power-efficiency.
Also decoding on a reasonably powerful (non-accelerated) cpu is fast enough for 1080p, not ideal for battery life but still.

Patent free video is in a strange space. I recently looked into just using old formats. To be super safe. With audio we have mp3 which is good enough for a lot of cases and seems to be patent free.
But for mpeg2 (used on DVD) even though it is really old (1995?) it is still patent encumbered in some places until 2035?

This author has worked on behalf of the patent parasite companies before so if you are left feeling "I need to pay these people" that may not be accurate.

Relevant: Have the patents for H.264 MPEG-4 AVC expired yet?

I never heard of Opus, so some links:
