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