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

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

238
239 If status is one of "downloading", or "finished", the

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