Solve the following python programming problem given the following code:
def main(argv) : 
    import optparse 
    def _check_fraction(option, opt, value) : 
        try : 
            return Fraction (value) 
except ValueError : 
            raise optparse.OptionValueError (('option %s: invalid rational value: %r' % (opt, value))) 
optparse.Option.TYPES += ('Fraction',) 
    optparse.Option.TYPE_CHECKER ['Fraction'] = _check_fraction 
    default_streamname = 'livestream' 
    usage = '%prog [options] URL [STREAM-NAME]' 
    epilog = ('URL should be of the form: rtmp://host[:port]/app, STREAM-NAME defaults to "%s".' % (default_streamname,)) 
    parser = optparse.OptionParser (usage = usage, epilog = epilog) 
    audio_choices = sorted (audio_codecs.keys ()) 
    video_choices = sorted (video_codecs.keys ()) 
    parser.add_option ('-a', '--audio-codec', action = 'store', dest = 'acodec', default = 'aac', choices = audio_choices, help = ('one of: %s.
(default: %%default)' % ', '.join (audio_choices))) 
    parser.add_option ('-v', '--video-codec', action = 'store', dest = 'vcodec', default = 'h264', choices = video_choices, help = ('one of: %s.
(default: %%default)' % ', '.join (video_choices))) 
    parser.add_option ('-r', '--audio-bitrate', action = 'store', dest = 'arate', type = 'float', help = 'audio bitrate in kbit/s (default: %default)', default = 64.0) 
    parser.add_option ('-R', '--video-bitrate', action = 'store', dest = 'vrate', type = 'float', help = 'video bitrate in kbit/s (default: %default)', default = 400.0) 
    parser.add_option ('-s', '--sample-rate', action = 'store', dest = 'srate', type = 'int', help = 'audio sample rate in Hz (default: speex: 32000, other codecs: 44100)') 
    parser.add_option ('-f', '--frame-rate', action = 'store', dest = 'frate', type = 'Fraction', help = 'video frame rate in frames/sec (default: %default)', default = '15/1') 
    parser.add_option ('-c', '--channels', action = 'store', dest = 'channels', type = 'int', help = 'number of audio channels (default: %default)', default = 1) 
    parser.add_option ('-W', '--width',...

    
    

    Fix the buggy line: run (url, stream_name, audio_codec = audio_codec, video_codec = video_codec, audio_bitrate = options.arate, video_bitrate = options.vrate, samplerate = options.srate, framerate = options.frate, channels = video_codec.channels, width = options.width, height = options.height, keyframe_interval = options.keyint, view = options.view)

#Here is Python code to fix the buggy line: run (url, stream_name, audio_codec = audio_codec, video_codec = video_codec, audio_bitrate = options.
