113 class YoutubeDL(object):
114 """YoutubeDL class.
115
116 YoutubeDL objects are the ones responsible of downloading the
117 actual video file and writing it to disk if the user has requested
118 it, among some other tasks. In most cases there should be one per
119 program. As, given a video URL, the downloader doesn't know how to
120 extract all the needed information, task that InfoExtractors do, it
121 has to pass the URL to one of them.
122
123 For this, YoutubeDL objects have a method that allows
124 InfoExtractors to be registered in a given order. When it is passed
125 a URL, the YoutubeDL object handles it to the first InfoExtractor it
126 finds that reports being able to handle it. The InfoExtractor extracts
127 all the information about the video or videos the URL refers to, and
128 YoutubeDL process the extracted information, possibly using a File
129 Downloader to download the video.
130
131 YoutubeDL objects accept a lot of parameters. In order not to saturate
132 the object constructor with arguments, it receives a dictionary of
133 options instead. These options are available through the params
134 attribute for the InfoExtractors to use. The YoutubeDL also
135 registers itself as the downloader in charge for the InfoExtractors
136 that are added to it, so this is a "mutual registration".

228 youtube_dl/postprocessor/__init__.py for a list.
229 as well as any further keyword arguments for the
230 postprocessor.
231 progress_hooks: A list of functions that get called on download
232 progress, with a dictionary with the entries
233 * status: One of "downloading", "error", or "finished".

235
236 If status is one of "downloading", or "finished", the

290 IP range in CIDR notation that will be used similarly to
291 geo_bypass_country
292
293 The following options determine which downloader is picked:
294 external_downloader: Executable of the external downloader to call.
295 None or unset for standard (built-in) downloader.
296 hls_prefer_native: Use the native HLS downloader instead of ffmpeg/avconv
297 if True, otherwise use ffmpeg/avconv if False, otherwise
298 use downloader suggested by extractor if None.
299
300 The following parameters are not used by YoutubeDL itself, they are used by
301 the downloader (see youtube_dl/downloader/common.py):
302 nopart, updatetime, buffersize, ratelimit, min_filesize, max_filesize, test,
303 noresizebuffer, retries, continuedl, noprogress, consoletitle,
304 xattr_set_filesize, external_downloader_args, hls_use_mpegts,
305 http_chunk_size.
306
307 The following options are used by the post processors:
308 prefer_ffmpeg: If False, use avconv instead of ffmpeg if both are available,
309 otherwise prefer ffmpeg.
310 postprocessor_args: A list of additional command-line arguments for the
311 postprocessor.
312
313 The following options are used by the Youtube extractor:
314 youtube_include_dash_manifest: If True (default), DASH manifests and related
315 data will be downloaded and processed by extractor.
316 You can reduce network I/O by disabling it if you don't
317 care about DASH.
