web based media manager

I’ve got a lot of local media stored, and some of them have the incorrect audio track selected as the default audio track.

I’ve fixed some of them manually with various incantations of command line tools, but I’m looking for a web based tool to do this for me.

Does anyone have a suggestion? I’m looking to change the default audio track and fix incorrect languages on the audio tracks primarily, and I’d like to avoid building something from scratch
