AV1 is the next-gen open-source royalty-free video codec created by the Alliance for Open Media (AOM), a group founded by Google, Mozilla, Cisco, Microsoft, Netflix, Amazon, and Intel. Apple is also a member.
We are finally seeing more hardware support for this codec. The new M3 chips from Apple support AV1 decode. The iPhone 15 Pro and iPhone 15 Pro Max also feature an AV1 hardware decoder.
The official Android 14 Compatibility Definition makes support for AV1 mandatory. The Snapdragon 8 Gen 2 chipset, widely used by Android phones released in 2023, supports AV1.
With the exception of Microsoft Edge, all browsers support AV1.
