> Hardware-accelerated video playback of H.264 (AVC), H.265 (HEVC) and VP9 video streams > Hardware-accelerated video recording into H.264 (AVC) and H.265 (HEVC) formats no mention of AV1? Surprised since most websites including YT uses it heavily.

The Qualcomm marketing spec sheet mentions AV1 decoding: https://www.qualcomm.com/content/dam/qcomm-martech/dm-assets/documents/Snapdragon-8-Elite-Gen-5-product-brief.pdf https://www.qualcomm.com/content/dam/qcomm-martech/dm-assets... Maybe that part of the driver isn't finished yet?

  Or licensed.

    Isn't the whole point of AV1 that it's royalty free, as opposed to H264/265/etc?
    - saagarjha 11mo ago
      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.
      - Dylan16807 11mo ago
        Have they successfully gotten any?
  - jeroenhd 11mo ago
    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.

  Yes. It is on the mailing list: https://lore.kernel.org/all/20251001-av1_irisdecoder-v1-0-9fb08f3b96a0@oss.qualcomm.com/ 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.
