mediaprobe

Parsing media files using bindings for getting information about codec, bitrate, dimensions, etc.

Prerequisites

It uses github.com/rakyll/magicmime for detect mimetypes and github.com/3d0c/gmf for parsing audio and video. See these packages for installation info.

TL;DR Installing on Ubuntu

1. You need go version 1.10 or higher
2. You need libmagic-dev

   sudo apt-get install libmagic-dev

3. You need ffmpeg libraries version 4.x or higher. You may compile it from sources, or use PPA. For example, ppa:jonathonf/ffmpeg-4

   sudo add-apt-repository ppa:jonathonf/ffmpeg-4
   sudo apt-get update
   sudo apt-get install libavcodec-dev libavdevice-dev libavfilter-dev \
                         libavformat-dev libavresample-dev libavutil-dev \
                         libpostproc-dev libswresample-dev libswscale-dev

Usage

See godoc examples.

Caveats

Detecting mimetype by magic number may not be accurate enough, bindings in Go often cause unexpected memory leaks.
