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

250 external_downloader: Executable of the external downloader to call.
251 None or unset for standard (built-in) downloader.
252 hls_prefer_native: Use the native HLS downloader instead of ffmpeg/avconv.
