#
# Get basic info about audio / video file (MP4, MP3, WAV, WEBM, ...) by ffprobe
#   - Usually you should have ffmpeg on your system, including ffprobe
#   - ffprobe gives you MUCH MUCH (MUCH) information
#   - this little helper script reduces ffprobe's info hell to typical core information
#     - use this script as a template for personal information interests 
#       - don't get mislead by "-v error" - it means "don't get verbose WITHOUT errors"
#   - information is given as JSON for readability & easy automated consumptione
