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

249 If it returns None, the video is downloaded.
250 match_filter_func in utils.py is one example for this.
251 no_color: Do not emit color codes in output.
253 The following options determine which downloader is picked:
254 external_downloader: Executable of the external downloader to call.
255 None or unset for standard (built-in) downloader.
256 hls_prefer_native: Use the native HLS downloader instead of ffmpeg/avconv.

261 noresizebuffer, retries, continuedl, noprogress, consoletitle,
262 xattr_set_filesize, external_downloader_args.
