Support Publisher metadata in MP4 tags

Crissov commented 1 year ago

In File_Mpeg4.cpp, there is no support for the ©pub and ©nrt boxes holding publisher and narrator information, respectively. Other less common fields are probably unsupported, too.

PS: It would be nice if MP4 tag support was properly documented on the homepage as well. Also, that page (like the source code repo) is too hard to find there.

We definitely don't have an exhaustive list, and we add items when we have files with that and time. We already need first to scan all the unsupported field names in the files we have.

This page is a lot outdated and would deserve more work, but this is not the priority of our sponsors so for when we have time for free work (not soon). Help would be appreciated there (the website is also open source).
