-
- File downloader objects are the ones responsible of downloading the

- 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.
- 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.
