class YoutubeDL:
"""YoutubeDL class.
YoutubeDL objects are the ones responsible of downloading the
actual video file and writing it to disk if the user has requested
it, among some other tasks. In most cases there should be one per
program. As, given a video URL, the downloader doesn't know how to
extract all the needed information, task that InfoExtractors do, it
has to pass the URL to one of them.
For this, YoutubeDL objects have a method that allows
InfoExtractors to be registered in a given order. When it is passed
a URL, the YoutubeDL object handles it to the first InfoExtractor it
finds that reports being able to handle it. The InfoExtractor extracts
all the information about the video or videos the URL refers to, and
YoutubeDL process the extracted information, possibly using a File
Downloader to download the video.
YoutubeDL objects accept a lot of parameters. In order not to saturate
the object constructor with arguments, it receives a dictionary of
options instead. These options are available through the params
attribute for the InfoExtractors to use. The YoutubeDL also
registers itself as the downloader in charge for the InfoExtractors
that are added to it, so this is a "mutual registration".
Available options:
username: Username for authentication purposes.
password: Password for authentication purposes.
videopassword: Password for accessing a video.
ap_mso: Adobe Pass multiple-system operator identifier.
ap_username: Multiple-system operator account username.
ap_password: Multiple-system operator account password.
usenetrc: Use netrc for authentication instead.
netrc_location: Location of the netrc file. Defaults to ~/.netrc.
netrc_cmd: Use a shell command to get credentials
verbose: Print additional info to stdout.
quiet: Do not print messages to stdout.
no_warnings: Do not print out anything for warnings.
forceprint: A dict with keys WHEN mapped to a list of templates to
print to stdout. The allowed keys are video or any of the
items in utils.POSTPROCESS_WHEN.
For compatibility, a single list is also accepted
print_to_file: A dict with keys WHEN (same as forceprint) mapped to
a list of tuples with (template, filename)
forcejson: Force printing info_dict as JSON.
dump_single_json: Force printing the info_dict of the whole playlist
(or video) as a single JSON line.
force_write_download_archive: Force writing download archive regardless
of 'skip_download' or 'simulate'.
simulate: Do not download the video files. If unset (or None),
simulate only if listsubtitles, listformats or list_thumbnails is used
format: Video format code. see "FORMAT SELECTION" for more details.
You can also pass a function. The function takes 'ctx' as
argument and returns the formats to download.
See "build_format_selector" for an implementation
allow_unplayable_formats: Allow unplayable formats to be extracted and downloaded.
ignore_no_formats_error: Ignore "No video formats" error. Usefull for
extracting metadata even if the video is not actually
available for download (experimental)
format_sort: A list of fields by which to sort the video formats.
See "Sorting Formats" for more details.
format_sort_force: Force the given format_sort. see "Sorting Formats"
for more details.
prefer_free_formats: Whether to prefer video formats with free containers
over non-free ones of same quality.
allow_multiple_video_streams: Allow multiple video streams to be merged
into a single file
allow_multiple_audio_streams: Allow multiple audio streams to be merged
into a single file
check_formats Whether to test if the formats are downloadable.
Can be True (check all), False (check none),
'selected' (check selected formats),
or None (check only if requested by extractor)
paths: Dictionary of output paths. The allowed keys are 'home'
'temp' and the keys of OUTTMPL_TYPES (in utils.py)
outtmpl: Dictionary of templates for output names. Allowed keys
are 'default' and the keys of OUTTMPL_TYPES (in utils.py).
For compatibility with youtube-dl, a single string can also be used
outtmpl_na_placeholder: Placeholder for unavailable meta fields.
restrictfilenames: Do not allow "&" and spaces in file names
trim_file_name: Limit length of filename (extension excluded)
windowsfilenames: Force the filenames to be windows compatible
ignoreerrors: Do not stop on download/postprocessing errors.
Can be 'only_download' to ignore only download errors.
Default is 'only_download' for CLI, but False for API

- If it returns None, the video is downloaded.
- If it returns utils.NO_DEFAULT, the user is interactively

downloads when a video is rejected.
match_filter_func in utils.py is one example for this.
color: A Dictionary with output stream names as keys

which are used when the given exe is used by the given PP.
Use 'default' as the name for arguments to passed to all PP
For compatibility with youtube-dl, a single list of args
can also be used
The following options are used by the extractors:
extractor_retries: Number of times to retry for known errors (default: 3)

for each video file, after all postprocessors have been
called. The filename will be passed as the only argument.
hls_prefer_native: - Use external_downloader = {'m3u8': 'native'} or {'m3u8': 'ffmpeg'}.
Use the native HLS downloader instead of ffmpeg/avconv

otherwise prefer ffmpeg.
