Displaying transcoding progress using string stone

I am using Rails Streamio gem to transcode a video file to .webm format. I can display the progress of the transcoding on the console using:

movie.transcode("public/uploads/#{current_user.id}/#{@userfile.name}.webm") { |progress| puts progress }

      

        
        
        
      

    

It shows progress on the console as follows:

My question is, how do I display this in the browser? Where can the user see the progress of the transcoding?
