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