I got mine to work with the following code, incase future devs stumble
across a similar situation:
module Paperclip
class ProcessAudio < Processor
attr_accessor :geometry, :whiny
def initialize(file, options = {}, attachment = nil)
super
@file = file
unless options[:geometry].nil?
if options[:geometry] == 'full'
@geometry = ''
elsif options[:geometry] == '30'
@geometry = '-t 30'
elsif options[:geometry] == '90'
@geometry = '-t 90'
end
end
@whiny = options[:whiny].nil? ? true : options[:whiny]
@basename = File.basename(@file.path, File.extname(@file.path))
end
def make
dst = Tempfile.new([ @basename, 'mp3' ].compact.join("."))
dst.binmode
cmd = "ffmpeg -i #[email protected]} #...@geometry} -acodec copy -y
#{File.expand_path(dst.path)}"
begin
success = Paperclip.run(cmd)
rescue PaperclipCommandLineError
raise PaperclipError, "There was an error processing the
preview for #...@basename}" if whiny
end
dst
end
end
end
