I've nearly got a perfect setup to encode my videos that I have. I have
the matroska format and metadata tags all set for languages,titles and
such for each track. I also have finally sorted out chapters... but:
When I input my ffmetadata file, I then go to mkvinfo and check my work;
what I find is that under the chapter display it shows the chapterstring
(as it terms it - title in other words), but under language it says und
(undetermined).
Pedantic as it may sound, it does bug me a bit. How do I change it?
The chapter stream is 0 (first input), and I've tried setting
chapterlanguage in the ffmetdata file, -metadata:s:m[:0] (both
iterations that is), -metadata:m, -metadata:i:0 all to no effect. What
is the method for this madness?
My ffmpeg is version 2.3.6.
Cheers
