"""YoutubeDL class.
|
|
|
|
YoutubeDL 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, YoutubeDL objects have a method that allows
|
|
InfoExtractors to be registered in a given order. When it is passed
|
|
a URL, the YoutubeDL object 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
|
|
YoutubeDL process the extracted information, possibly using a File
|
|
Downloader to download the video.
|
|
|
|
YoutubeDL objects 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 YoutubeDL also
|
|
registers itself as the downloader in charge for the InfoExtractors
|
|
that are added to it, so this is a "mutual registration".
