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

265 noresizebuffer, retries, continuedl, noprogress, consoletitle,
266 xattr_set_filesize, external_downloader_args, hls_use_mpegts.
