- """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 returns
- all the information to the FileDownloader and the latter downloads the
- file or does whatever it's instructed to do.
-
- 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 get_params()
- method 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.
- format: Video format code.
- outtmpl: Template for output names.
