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 acces a video. usenetrc: Use netrc for authentication instead. verbose: Print additional info to stdout. quiet: Do not print messages to stdout. forceurl: Force printing final URL. forcetitle: Force printing title. forceid: Force printing ID. forcethumbnail: Force printing thumbnail URL. forcedescription: Force printing description. forcefilename: Force printing final filename. forceduration: Force printing duration. forcejson: Force printing info_dict as JSON. simulate: Do not download the video files. format: Video format code. format_limit: Highest quality format to try. outtmpl: Template for output names. restrictfilenames: Do not allow "&" and spaces in file names ignoreerrors: Do not stop on download errors. nooverwrites: Prevent overwriting files. playliststart: Playlist item to start at. playlistend: Playlist item to end at. matchtitle: Download only matching titles. rejecttitle: Reject downloads for matching titles. logger: Log messages to a logging.Logger instance. logtostderr: Log messages to stderr instead of stdout. writedescription: Write the video description to a .description file writeinfojson: Write the video description to a .info.json file writeannotations: Write the video annotations to a .annotations.xml file writethumbnail: Write the thumbnail image to a file writesubtitles: Write the video subtitles to a file writeautomaticsub: Write the automatic subtitles to a file allsubtitles: Downloads all the subtitles of the video (requires writesubtitles or writeautomaticsub) listsubtitles: Lists all available subtitles for the video subtitlesformat: Subtitle format [srt/sbv/vtt] (default=srt) subtitleslangs: List of languages of the subtitles to download keepvideo: Keep the video file after post-processing daterange: A DateRange object, download only if the upload_date is in the range. skip_download: Skip the actual download of the video file cachedir: Location of the cache files in the filesystem. None to disable filesystem cache. noplaylist: Download single video instead of a playlist if in doubt. age_limit: An integer representing the user's age in years. Unsuitable videos for the given age are skipped. min_views: An integer representing the minimum view count the video must have in order to not be skipped. Videos without view count information are always downloaded. None for no limit. max_views: An integer representing the maximum view count. Videos that are more popular than that are not downloaded. Videos without view count information are always downloaded. None for no limit. download_archive: File name of a file where all downloads are recorded. Videos already present in the file are not downloaded again. cookiefile: File name where cookies should be read from and dumped to. nocheckcertificate:Do not verify SSL certificates proxy: URL of the proxy server to use socket_timeout: Time to wait for unresponsive hosts, in seconds bidi_workaround: Work around buggy terminals without bidirectional text support, using fridibi debug_printtraffic:Print out sent and received HTTP traffic The following parameters are not used by YoutubeDL itself, they are used by the FileDownloader: nopart, updatetime, buffersize, ratelimit, min_filesize, max_filesize, test, noresizebuffer, retries, continuedl, noprogress, consoletitle """ params = None _ies = [] _pps = [] _download_retcode = None _num_downloads = None _screen_file = None def __init__(self, params=None): """Create a FileDownloader object with the given options.""" if params is None: params = {} self._ies = [] self._ies_instances = {} self._pps = [] self._progress_hooks = [] self._download_retcode = 0 self._num_downloads = 0 self._screen_file = [sys.stdout, sys.stderr][params.get('logtostderr', False)] self._err_file = sys.stderr self.params = params if params.get('bidi_workaround', False): try: import pty master, slave = pty.openpty() width = get_term_width() if width is None: width_args = [] else: width_args = ['-w', str(width)] sp_kwargs = dict( stdin=subprocess.PIPE, stdout=slave, stderr=self._err_file) try: self._output_process = subprocess.Popen( ['bidiv'] + width_args, **sp_kwargs ) except OSError: self._output_process = subprocess.Popen( ['fribidi', '-c', 'UTF-8'] + width_args, **sp_kwargs) self._output_channel = os.fdopen(master, 'rb') except OSError as ose: if ose.errno == 2: self.report_warning('Could not find fribidi executable, ignoring --bidi-workaround .
