Overview

AviGlitch provides the ways to glitch AVI formatted video files.

Synopsis:

You can manipulate each frame, like:

avi = AviGlitch.open '/path/to/your.avi'
avi.frames.each do |frame|
  if frame.is_keyframe?
    frame.data = frame.data.gsub(/\d/, '0')
  end
end
avi.output '/path/to/broken.avi'

Using the method glitch, it can be written like:

avi = AviGlitch.open '/path/to/your.avi'
avi.glitch(:keyframe) do |data|
  data.gsub(/\d/, '0')
end
avi.output '/path/to/broken.avi'

Since v0.2.2, it allows to specify the temporary directory. This library duplicates and processes a input file in the temporary directory, which by default is Dir.tmpdir. To specify the custom temporary directory, use tmpdir: option, like:

avi = AviGlitch.open '/path/to/your.avi', tmpdir: '/path/to/tmpdir'
