Chapter titles not appearing on iOS 11 Videos app

[Mazhar Hussain]

Titles for chapters are not appearing in the videos app. I'm on iOS 11.1.1 on an iphone 8. Here is an example:

This only affects movies created with subler and not movies downloaded from the iTunes store.

Here is the movie subler makes:

Here is a movie downloaded from the store:

The only difference is that the chapter track for the movie downloaded from the store is in tx3g format, whereas the one that subler creates is in text format.

I can't test if this is the reason since I don't know how to create a chapter track in tx3g format.

Could you add a toggle so a user can choose from either text or tx3g formats when adding a chapter track.

Thanks.

I tested this years ago, and it wasn't that the issue.
