[Development] Qt Multimedia API to get chapter information from audio/video file

[Wang Gary]

Hi,

Currently Qt's Multimedia API lack the ability to retrieve chapter/TOC
information from media files, although both Gstreamer and FFmpeg
backend support such functionality. I've created a report for this
suggestion: QTBUG-130320

I'm not sure if someone already start working on such feature. I'm
interested to work on this personally and upstream such feature, but
not sure if it's acceptable, and if so, what the final API should look
like. I described one of the possible approach in that bugreport. Any
recommendations and/or suggestions?

Thanks!
Gary
