The Qualcomm marketing spec sheet mentions AV1 decoding: https://www.qualcomm.com/content/dam/qcomm-martech/dm-assets...

Maybe that part of the driver isn't finished yet?

Yes. It is on the mailing list: https://lore.kernel.org/all/20251001-av1_irisdecoder-v1-0-9f...

It actually introduces new things into the UAPI because no one else did fully-stateful AV1 decode before.

Or licensed.

Isn't the whole point of AV1 that it's royalty free, as opposed to H264/265/etc?

For the codec, sure. But there can always be more restrictions on the IP block, driver code, etc.

Yeah, and the main problem with HEVC/H265 is the patent encumbrance. Very odd, but hopefully it's just coming a bit later.

It started like that. But now there are at least 2 different patent pools that want rent.

Have they successfully gotten any?

AV1 is designed to be license free, so unless they outsourced their driver development to another company I don't think there's anything to license.
