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

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

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

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