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