ffprobe -hide_banner Outlander.S04E13.Man.of.Worth.mkv Change container without re-encoding (fast, no quality loss):

ffmpeg -i Outlander.S04E13.Man.of.Worth.mkv -vn -acodec mp3 -ab 192k Outlander.S04E13.mp3 Get duration first:

ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 Outlander.S04E13.Man.of.Worth.mkv Then extract last 5 minutes (assuming total duration 2700 seconds):
