Is it possible to check if a video file has a subtitle using bash and get a simple answer like "yes" or "no". I don't need to know any details about the subtitles.
Maybe using ffmpeg?
This should display a 0 if subtitles are found, and any other value if not found.
ffmpeg -i video -c copy -map 0:s:0 -frames:s 1 -f null - -v 0 -hide_banner; echo $?
