+class FileDownloader(object):
+ """File Downloader class.
+
+ File downloader 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, file downloader objects have a method that allows
+ InfoExtractors to be registered in a given order. When it is passed
+ a URL, the file downloader 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
+ asks the FileDownloader to process the video information, possibly
+ downloading the video.
+
+ File downloaders 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 FileDownloader 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.
+ usenetrc: Use netrc for authentication instead.
+ quiet: Do not print messages to stdout.
+ forceurl: Force printing final URL.
+ forcetitle: Force printing title.
+ forcethumbnail: Force printing thumbnail URL.
+ forcedescription: Force printing description.
+ forcefilename: Force printing final filename.
+ simulate: Do not download the video files.
+ format: Video format code.
+ format_limit: Highest quality format to try.
+ outtmpl: Template for output names.
+ ignoreerrors: Do not stop on download errors.
+ ratelimit: Download speed limit, in bytes/sec.
+ nooverwrites: Prevent overwriting files.
+ retries: Number of times to retry for HTTP error 5xx
+ continuedl: Try to continue downloads if possible.
+ noprogress: Do not print the progress bar.
+ playliststart: Playlist item to start at.
+ playlistend: Playlist item to end at.
+ matchtitle: Download only matching titles.
+ rejecttitle: Reject downloads for matching titles.
+ logtostderr: Log messages to stderr instead of stdout.
+ consoletitle: Display progress in console window's titlebar.
+ nopart: Do not use temporary .part files.
+ updatetime: Use the Last-modified header to set output file timestamps.
+ writedescription: Write the video description to a .description file
+ writeinfojson: Write the video description to a .info.json file
+ writesubtitles: Write the video subtitles to a .srt file
+ subtitleslang: Language of the subtitles to download
