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