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:
{
"streams": [

"index": 0,
"type": "video",
"codec": "h264",
"start_time": 0.041708,

},
{

"codec": "aac",

}
]
}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.
