Thanks for the speedy reply. As mentioned in my email my questions aren't
about getting it to work. I can write the metadata just fine (ex: my most
recent one was ffmpeg -i input.mp4 -metadata media_type="10" -metadata
show="Law & Order" -metadata season_number="1" -metadata
title="Prescription For Death" -metadata episode_id="66209" -metadata
episode_sort="1" -metadata:s:a:0 language=eng -c:v libx264 -c:a aac
output.mp4). This writes fine and gives me the results I expect.
My questions are about finding the full scope of keys that can be written
with ffmpeg because the sites I reference give varying sets of keys. I
would like to find a comprehensive list of keys for all files in general
(video and audio) but for mp4 in particular. I would also like to know
about writing custom tags/keys. Is this possible for mp4 in general but
more importantly mp4 with ffmpeg. :-D
