+
+ 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.

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

- 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.
