Apple has acquiesced to demands from companies such as Google and Netflix by announcing the release of Safari 16.4 beta with support for AV1 video decoding. It is not yet clear whether this will affect the mobile version of the browser, which has a much larger number of users. For example, the mobile version of the Safari browser still does not fully support the VP9 codec.
The AV1 video codec is developed by the Open Media Alliance (AOMedia), which includes companies such as Mozilla, Google, Microsoft, Intel, ARM, NVIDIA, IBM, Cisco, Amazon, Netflix, AMD, VideoLAN, Apple, CCN, and Realtek. AV1 is positioned as a royalty-free, open-source video encoding format that is well ahead of H.264 and VP9 in terms of compression.
