    """YoutubeDL class.
 | 
						|
 | 
						|
    YoutubeDL objects are the ones responsible of downloading the
 | 
						|
    actual video file and writing it to disk if the user has requested
 | 
						|
    it, among some other tasks. In most cases there should be one per
 | 
						|
    program. As, given a video URL, the downloader doesn't know how to
 | 
						|
    extract all the needed information, task that InfoExtractors do, it
 | 
						|
    has to pass the URL to one of them.
 | 
						|
 | 
						|
    For this, YoutubeDL objects have a method that allows
 | 
						|
    InfoExtractors to be registered in a given order. When it is passed
 | 
						|
    a URL, the YoutubeDL object handles it to the first InfoExtractor it
 | 
						|
    finds that reports being able to handle it. The InfoExtractor extracts
 | 
						|
    all the information about the video or videos the URL refers to, and
 | 
						|
    YoutubeDL process the extracted information, possibly using a File
 | 
						|
    Downloader to download the video.
 | 
						|
 | 
						|
    YoutubeDL objects accept a lot of parameters. In order not to saturate
 | 
						|
    the object constructor with arguments, it receives a dictionary of
 | 
						|
    options instead. These options are available through the params
 | 
						|
    attribute for the InfoExtractors to use. The YoutubeDL also
 | 
						|
    registers itself as the downloader in charge for the InfoExtractors
 | 
						|
    that are added to it, so this is a "mutual registration".
 | 
						|
 | 
						|
    Available options:
 | 
						|
