    # format: We don't set a default format. Youtube-dl will choose the best option for us automatically.
    # Since the end of April 2015 and version 2015.04.26 youtube-dl uses -f bestvideo+bestaudio/best as default format selection (see #5447, #5456). 
    # If ffmpeg or avconv are installed this results in downloading bestvideo and bestaudio separately and muxing them together into a single file giving the best overall quality available. 
    # Otherwise it falls back to best and results in downloading best available quality served as a single file.
    # best is also needed for videos that don't come from YouTube because they don't provide the audio and video in two different files.
