Support chaptering in bluray

[ixian]

Summary of the bug:

I am trying to extract chapter markers from a bluray mounted on my file system with ffprobe. Using

ffprobe -i bluray:/mnt/bluray -show_chapters

The output does not contain any chapter information. See below:

[clover@hexapod ~]$ ffprobe bluray:/mnt/bluray -show_chapters 2>&1

I am sure the bluray contains chapter markers, which I have succesfully extracted with eac3to. But, because of platform compatibility, I would like to use ffmpeg for this.

[Clément Bœsch]

Exporting chapters can be done through avpriv_new_chapter() which takes a AVFormatContext. Unfortunately we support BluRay through our protocol layer instead of format, and as such has no access to that format context. This will probably require some some sort of design change.

You should treat things like bluray support as demuxers (with a "slave" mpeg-ts demuxer). Worked for me in mpv.
