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