Opus CAF audios no longer working with newer ffmpeg and ShareX

I’m using ShareX to capture Opus audio, which I then use ffmpeg to convert store in a caf container, then name as .ogg for compatibility. However, it seems that with the update to ShareX 16.0 and or using newer versions of ffmpeg than in ShareX 15.0, the audios stopped working in AnkiMobile, but work on PC. They play, but no audio can be heard.

Apparently, iOS supports opus since iOS 17, so is it possible to add opus support?

AnkiMobile uses iOS’s media playing tools. If certain formats are not playing in AnkiMobile, I’m afraid that implies that iOS does not currently support them.
