video_dimensions

Quick and easy video attributes -- width, height, bitrate, codec, duration, framerate. Inspired by Sam Stephenson's Dimensions gem.

Features

Seamlessly supports multiple "backends" for sussing out video attributes, so it will try to find whatever utility the system has available (see Supported Backends) and use that.

Examples

require 'video_dimensions'

VideoDimensions.dimensions('~/Movies/720p.wmv') # => [1280, 720]
VideoDimensions.width('~/Movies/720p.wmv')      # => 1280
VideoDimensions.height('~/Movies/720p.wmv')     # => 720
VideoDimensions.bitrate('~/Movies/720p.wmv')    # => 5904
VideoDimensions.codec('~/Movies/720p.wmv')      # => "WMV3"
VideoDimensions.duration('~/Movies/720p.wmv')   # => "00:00:02"
VideoDimensions.framerate('~/Movies/720p.wmv')  # => 21.83

v = VideoDimensions('~/Movies/720p.wmv')
v.dimensions # => [1280, 720]
v.width      # => 1280
v.height     # => 720
v.bitrate    # => 5904
v.codec      # => "WMV3"
v.duration   # => "00:00:02"
v.framerate  # => 21.83

Requirements

One of the supported backends available in the system's $PATH.
