[Libav-user] FFmpeg and Apple's transition to ARM/Apple Silicon

[Info || Non-Lethal Applications]

With Apple’s recent announcement of moving from Intel to their own (ARM based) processors, I’m wondering what this means for FFmpeg users.
I’m using the FFmpeg libraries as base for a - currently Mac-only - video player so it is crucial for me that things will still work after the switch.

I have ordered a Developer Kit and will get it next week so I’ll be able to conduct some tests myself.
I was really just wondering what to expect. 

Will re-compiling the libraries on the new architecture be enough to make everything work "as before"?
As FFmpeg makes a fair use of assembler and I think also some processor specific optimizations as far as I know that may not be available on ARM, will the performance likely be worse?

Sorry for my lack of knowledge on the low-level side of things and thanks for sharing your thoughts in advance!

Best regards,

Flo
