What are the Mac hardware and software requirements to decode and encode MV-HEVC video with AVFoundation?
Many of the new MV-HEVC-related keys require macOS 14.0+, so I'm guessing that macOS Sonoma or later is required on the software side.
What about processor architectures? I can read an MV-HEVC source on my Apple Silicon M1. But when I run the same code on my Intel Mac mini (2018) running Sonoma 14.3, AVAssetReader's startReading() returns false.
Similarly, when I try to create an AVAssetWriterInput with MV-HEVC output settings, I receive:
-[AVAssetWriterInput initWithMediaType:outputSettings:sourceFormatHint:] Compression property MVHEVCVideoLayerIDs is not supported for video codec type hvc1'
Is this because Intel-based Macs don't support MV-HEVC? Or am I missing something else?
