# 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'
#
