Encoding with hevc_videotoolbox (hardware) using Mac OS Sonoma 14.3.1 on M1 fails with error

[D Holo]

hevc_videotoolbox encoding fails after update to Mac OS Sonoma on Apple M1 hardware.

The same ffmpeg binary worked on previous Mac OS, for example on Venture or Big Sur.

Below are two logs.

The first log shows it failing on Sonoma and the second log working on Macs OS Big Sur.

I've used the latest and greatest static build (N-113723-g80131321c4-tessus) for the purposes of demonstrating.

The input and output file can be substituted as required as it does not appear to be related to the media.

The error given is "error: cannot create compression session: -12908"

Thank-You very much.
