  • Running a 2-pass video conversion using Python's subprocess module and ffmpeg

    22 novembre 2012, par ensnare

    I'm trying to convert a bunch of videos to play on my iPad. I'm using the subprocess module, which from what I understand launches a binary in a separate process from my script. I'm not sure how to handle 2-pass encoding which requires that the first process terminate before the second begin.

    Here is my code :

    def convert(filename):
    
  extension = filename[-3:]
    

    
  destination_filename_720 = filename[-4:] + '-a720p' + '.mp4'
    
  destination_filename_1080 = filename[-4:] + '-a1080p' + '.mp4'
    

    
  p = subprocess.Popen(['ffmpeg','-i', str(filename) ,
    
                        '-acodec' , 'aac' ,
    
                        '-ab' , '160k' ,
    
                        '-ac' , '2' ,
    
                        '-vcodec' , 'libx264' ,
    
                        '-strict' , '-2' ,
    
                        '-vpre' , 'ipod640' ,
    
                        '-threads' , '8' ,
    
                        '-s' , '1280x720' ,
    
                        '-b:v' , '2000k' ,
    
                        '-pass' , '1' ,
    
                        '-y' ,
    
                        destination_filename_720])
    

    
  p = subprocess.Popen(['ffmpeg','-i', str(filename) ,
    
                        '-acodec' , 'aac' ,
    
                        '-ab' , '160k' ,
    
                        '-ac' , '2' ,
    
                        '-vcodec' , 'libx264' ,
    
                        '-strict' , '-2' ,
    
                        '-vpre' , 'ipod640' ,
    
                        '-threads' , '8' ,
    
                        '-s' , '1280x720' ,
    
                        '-b:v' , '2000k' ,
    
                        '-pass' , '2' ,
    
                        '-y' ,
    
                        destination_filename_720])

    As soon as the convert() function is called, both processes are spawned immediately.

    The second process fails because the first process hasn't yet finished.

    How can I fix this ? Or, is there a better way ?
