Dired; Is it possible, to show video duration as column in dired view?

Question

i want to let dired show the duration of multimedia files as a column inside the dired buffer detail view.

Is it possible? Any third-party extensions for dired?

Currently i use exiftool -T -ImageSize -XResolution -YResolution -VideoFrameRate -AvgBitRate -Duration as shell command run on marked files. But this produce only output. I don't know how to insert this result as columns.

My short answer is no. Depending on what you really want, it's not possible - not without more or less redesigning Dired. Dired is essentially about ls listings.

But you might try setting variable insert-directory-program to a program that produces the kind of listing you want - that should be possible. But you might not then be able to use some Dired features. Worth a try anyway.

And you might find some Dired 3rd-party library that tries to add additional, arbitrary columns, so you could make use of that. Perhaps someone else will let you know here about such a library.
