thx for the answers guys!

but still, i cant get the output into my array. below is the code im
using - what am i doing wrong?

cheers, chris

	def do_convert
		#testcode
		#convert file
		puts "STARTING CONVERSION..."
		op = ["ffmpeg result/output:".upcase, " "]
		
		#using ls instead of ffmpeg, so everyone can test this
		IO.popen("ls") do |l|
			op.insert(-1, l)				
		end

		#i also tried "p = IO.popen('ls')" and then
		#my_array = p.readlines, but with the same result
		
		#display output
		op.each do |line|
			puts line
		end
		
	end
