87 class YoutubeDL(object):
90 YoutubeDL objects are the ones responsible of downloading the
91 actual video file and writing it to disk if the user has requested
92 it, among some other tasks. In most cases there should be one per
93 program. As, given a video URL, the downloader doesn't know how to
94 extract all the needed information, task that InfoExtractors do, it
95 has to pass the URL to one of them.
97 For this, YoutubeDL objects have a method that allows
98 InfoExtractors to be registered in a given order. When it is passed
99 a URL, the YoutubeDL object handles it to the first InfoExtractor it
100 finds that reports being able to handle it. The InfoExtractor extracts
101 all the information about the video or videos the URL refers to, and
102 YoutubeDL process the extracted information, possibly using a File
103 Downloader to download the video.
105 YoutubeDL objects accept a lot of parameters. In order not to saturate
106 the object constructor with arguments, it receives a dictionary of
107 options instead. These options are available through the params
108 attribute for the InfoExtractors to use. The YoutubeDL also
109 registers itself as the downloader in charge for the InfoExtractors
110 that are added to it, so this is a "mutual registration".
