probe is a small command-line utility which prints JSON-formatted information about a video or audio file fed via stdin, with the help of the excellent ffmpeg/libav framework(s).
It produces the following report for the theatrical trailer for Wes Anderson's Grand Budapest Hotel:

You'll be good to go if pkg-config --print-errors --exists libavcodec libavformat libavutil
runs without complaining. Otherwise, install either ffmpeg or libav using
your favourite package manager.
