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