"""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. |
|
simulate: Do not download the video files. |
|
format: Video format code. |
|
outtmpl: Template for output names. |
|
ignoreerrors: Do not stop on download errors. |
|
ratelimit: Download speed limit, in bytes/sec. |

nooverwrites: Prevent overwriting files. |
