[FFmpeg-user] concat muxer: Preserve embedded metadata?

[Peter B.]

Hello everyone :)

I just realized that when using the concat muxer (with a list of 
filenames in a textfile), embedded metadata (title, date, etc) of the 
source files is left behind and not copied through to the created output.

I understand that it's not trivial/clear to decide *which* metadata from 
which source file(s) to keep, but is there any way to at least say "use 
metadata from the 1st file"?
(which may probably satisfy a lot of use-cases, as the descriptive 
metadata will probably match the rest too?)


Grateful for any suggestions :)


Thanks,
Peter
