Right, when we launched devices with hardware HEVC we did provide a software video decoder for devices without it (for non-protected content only).

I’ve got nothing to announce on that score regarding AV1, though. iOS 17 will support software AV1 decode, but only for still images (AVIF).

If you wish, you can use the SCORE attribute to make the client prefer AV1 over other encodings (but please continue to provide renditions encoded with AVC and/or HEVC for compatibility with earlier devices and AirPlay).
