macOS Seconds into time format

[i.yalovecky]

I'm getting info about file duration by kMDItemDurationSeconds of MDItem, so i want to expose its to user in readable format. How i can do it? Thanks.

And may be somebody already has any code what grab info from audio-video files?

According to the docs, kMDItemDurationSeconds is stored as a CFNumber (NSNumber if in Cocoa). Once you pull out the primitive value, it's just a few math operations to format it. But you need to choose a format option first (for example HH:MM:SS).

And may be somebody already has any code what grab info from audio-video files?

What kind of info?

What kind of info?

When iTunes firstly opened audio-cd, it downloads data for it from internet. Where it stores it and how i can access to this data?
