Description

When using the FFmpeg native AAC encoder, it will produce audio/video files that are not playable on macOS.
You need to add -aac_pred 1 to make it work (read: movies are then playable on macOS).

So it is advisable to enable this by default when using the native AAC encoder.

But that just does AAC Main profile... It is a bug in MacOS.

Replying to Balling:

Yes, that's true.

I tried with OSX10.6 up to macOS 12.5 and it never worked when encoding with the native AAC encoder. It does work when using LibFAAC or AudioToolBox aac_at. Both also produces AAC(LS) and do playback fine on macOS.

So, my guess is that the native AAC encoder is doing (something) wrong when creating AAC(LS).
