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

255 match_filter_func in utils.py is one example for this.
256 no_color: Do not emit color codes in output.
258 The following options determine which downloader is picked:
259 external_downloader: Executable of the external downloader to call.
260 None or unset for standard (built-in) downloader.
261 hls_prefer_native: Use the native HLS downloader instead of ffmpeg/avconv.

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