56 class YoutubeDL(object):
59 YoutubeDL objects are the ones responsible of downloading the
60 actual video file and writing it to disk if the user has requested
61 it, among some other tasks. In most cases there should be one per
62 program. As, given a video URL, the downloader doesn't know how to
63 extract all the needed information, task that InfoExtractors do, it
64 has to pass the URL to one of them.
66 For this, YoutubeDL objects have a method that allows
67 InfoExtractors to be registered in a given order. When it is passed
68 a URL, the YoutubeDL object handles it to the first InfoExtractor it
69 finds that reports being able to handle it. The InfoExtractor extracts
70 all the information about the video or videos the URL refers to, and
71 YoutubeDL process the extracted information, possibly using a File
72 Downloader to download the video.
74 YoutubeDL objects accept a lot of parameters. In order not to saturate
75 the object constructor with arguments, it receives a dictionary of
76 options instead. These options are available through the params
77 attribute for the InfoExtractors to use. The YoutubeDL also
78 registers itself as the downloader in charge for the InfoExtractors
79 that are added to it, so this is a "mutual registration".
