Issues with FFmpeg (and Movie Maker) - need chmod and the binary is the wrong CPU type

Most appropriate sub-area of Processing 4?

Utilities

Processing version

4.4.4

Operating system

MacOS 11.7.10 (Big Sur)

Steps to reproduce this

1.Install 'Movie Maker II' via Tools > Manage Tools.
2.Run Movie Maker.
3. Movie Maker gives the error 'Creating the QuickTime movie failed. Cannot run program "... frmpeg": error=13, Permission denied'
4. Use 'ls' in Terminal to view ffmpeg's permissions. They are '-rw-r--r--'.
5. Use 'chmod' in Terminal to change ffmpeg's permissions to '-rwxr--r-'.
6. Run Movie Maker again.
7. Movie Maker gives the error 'Creating the QuickTime movie failed. Cannot run program "... frmpeg": error=86, bad CPU type in executable.'
8. If I download the 'static FFmpeg binary for macOS 64-bit Intel' from https://evermeet.cx/ffmpeg/ and replace the existing 'ffmpeg', Movie Maker works okay.

No

Commencez par reproduire l’installation de Movie Maker II et la création d’un film sur macOS 11.7.10, puis examinez les permissions et l’architecture du processeur de ffmpeg installé. C’est terminé lorsque l’exécutable inclus peut s’exécuter sans chmod manuel ni remplacement et que Movie Maker crée correctement un film QuickTime.
