macOS and iOS have native support for HEVC video, but only with hvc1 tagging instead of hev1 tagging. This snippet "fixes" it "in place" without reencoding anything, so it's almost instant. I use it to make direct-to-disk recordings from my CCTV cameras playable in browser/QuickTime/QuickLook without needing VLC.
