Inspecting with mp4chaps, it turns out the chapter mark produced by
ffmpeg for mp4 files are of Nero format. It is easy to convert it to
quicktime format with mp4chaps, often found in mp4v2-utils package.

The quicktime chapter format is recognized in iOS 7 if it is
categorized as "Movie" instead of "Home Video". This is a very unusual
case, where categorization decided whether or not chapter marks are
For Android, neither chapter mark formats are natively supported.
Simple players App like "Simple Cinema" can use Nero format. It may be
able to use Quitcktime format too, against which I haven't tested.
