The files have multiple tracks, the standard audio and video and 3 metadata tracks. I'm using the command line option -map 0:m:handler_name:"" to identify the tracks to copy. Given a single file this works as expected, but as soon as concat has multiple files the track metadata is lost and the handler_name match fails due to this early return. Each of the tracks I'm selected are able to be concatenated just fine, much like the a/v tracks. It's not about the file metadata, it's the track metadata which is needed for track identification which I'm looking to preserve. Does that make sense?
