class YoutubeDL:
    """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:

    username:          Username for authentication purposes.
    password:          Password for authentication purposes.
    videopassword:     Password for accessing a video.

                       items in utils.POSTPROCESS_WHEN.

                       Must only be used along with sleep_interval.
                       Actual sleep time will be a random float from range
                       [sleep_interval; max_sleep_interval].
    sleep_interval_subtitles: Number of seconds to sleep before each subtitle download
    listformats:       Print an overview of available video formats and exit.
    list_thumbnails:   Print a table of all thumbnails and exit.
    match_filter:      A function that gets called for every video with the signature
                       (info_dict, *, incomplete: bool) -> Optional[str]
                       For backward compatibility with youtube-dl, the signature
                       (info_dict) -> Optional[str] is also allowed.
                       - If it returns a message, the video is ignored.
                       - If it returns None, the video is downloaded.
                       - If it returns utils.NO_DEFAULT, the user is interactively
                         asked whether to download the video.
                       match_filter_func in utils.py is one example for this.
    no_color:          Do not emit color codes in output.

                       HTTP header

                       X-Forwarded-For HTTP header
    geo_bypass_ip_block:
                       IP range in CIDR notation that will be used similarly to
                       geo_bypass_country
    external_downloader: A dictionary of protocol keys and the executable of the
                       external downloader to use for it. The allowed protocols
                       are default|http|ftp|m3u8|dash|rtsp|rtmp|mms.
                       Set the value to 'native' to use the native downloader
    compat_opts:       Compatibility options. See "Differences in default behavior".
                       The following options do not work when used through the API:
                       filename, abort-on-error, multistreams, no-live-chat, format-sort

                       'download-title' (console title) and 'postprocess-title'.
                       The template is mapped on a dictionary with keys 'progress' and 'info'
    retry_sleep_functions: Dictionary of functions that takes the number of attempts
                       as argument and returns the time to sleep in seconds.
                       Allowed keys are 'http', 'fragment', 'file_access'
    download_ranges:   A callback function that gets called for every video with
                       the signature (info_dict, ydl) -> Iterable[Section].
                       Only the returned sections will be downloaded.
                       Each Section is a dict with the following keys:

                       * end_time: End time of the section in seconds
                       * title: Section title (Optional)
                       * index: Section number (Optional)

    noprogress:        Do not print the progress bar
    live_from_start:   Whether to download livestreams videos from the start

    The following parameters are not used by YoutubeDL itself, they are used by
    the downloader (see yt_dlp/downloader/common.py):
    nopart, updatetime, buffersize, ratelimit, throttledratelimit, min_filesize,
    max_filesize, test, noresizebuffer, retries, file_access_retries, fragment_retries,
    continuedl, xattr_set_filesize, hls_use_mpegts, http_chunk_size,
    external_downloader_args, concurrent_fragment_downloads.

    The following options are used by the post processors:
    ffmpeg_location:   Location of the ffmpeg/avconv binary; either the path
                       to the binary or its containing directory.
    postprocessor_args: A dictionary of postprocessor/executable keys (in lower case)
                       and a list of additional command-line arguments for the
                       postprocessor/executable. The dict can also have "PP+EXE" keys
                       which are used when the given exe is used by the given PP.
                       Use 'default' as the name for arguments to passed to all PP
                       For compatibility with youtube-dl, a single list of args
                       can also be used

    The following options are used by the extractors:
    extractor_retries: Number of times to retry for known errors
    dynamic_mpd:       Whether to process dynamic DASH manifests (default: True)
    hls_split_discontinuity: Split HLS playlists to different formats at
                       discontinuities such as ad breaks (default: False)
    extractor_args:    A dictionary of arguments to be passed to the extractors.
                       See "EXTRACTOR ARGUMENTS" for details.
                       E.g. {'youtube': {'skip': ['dash', 'hls']}}
    mark_watched:      Mark videos watched (even with --simulate). Only for YouTube

    The following options are deprecated and may be removed in the future:

    force_generic_extractor: Force downloader to use the generic extractor

                       You can reduce network I/O by disabling it if you don't
