Usage

For an audio source, a typical OptionParser option and it's use looks like:

    parser.add_option("-O", "--audio-output", type="string", default="",
                       help="pcm device name.  E.g., hw:0,0 or surround51 or /dev/dsp")
    audio_rate = 32e3
    audio_sink = audio.sink (int (audio_rate), options.audio_output)

Similarly, an audio sink would have a typical OptionParser option and its use would look like:

    parser.add_option("-I", "--audio-input", type="string", default="",
                      help="pcm input device name.  E.g., hw:0,0 or /dev/dsp")
    audio_rate = 32e3
    audio_source = audio.source(int(audio_rate), audio_input)
