I’m looking for a way to batch analyse dozens of mkv files and getting a full list of all audio tracks per file. Is that something I can do with MKVToolNix? I’m not really finding anything online
Welcome!
You can use mkvmerge’s JSON identification mode for any kind of custom scripting, e.g. mkvmerge --identification-mode json --identify "your file.mkv"
or its shortcut mkvmerge -J "your file.mkv"
