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