"""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 acces a video.
|
|
usenetrc: Use netrc for authentication instead.
|
|
verbose: Print additional info to stdout.
|
|
quiet: Do not print messages to stdout.
|
|
forceurl: Force printing final URL.
|
|
forcetitle: Force printing title.
|
|
forceid: Force printing ID.
|
|
forcethumbnail: Force printing thumbnail URL.
|
|
forcedescription: Force printing description.
|
|
forcefilename: Force printing final filename.
|
|
simulate: Do not download the video files.
|
|
format: Video format code.
|
|
format_limit: Highest quality format to try.
|
|
outtmpl: Template for output names.
|
|
restrictfilenames: Do not allow "&" and spaces in file names
|
|
ignoreerrors: Do not stop on download errors.
|
|
nooverwrites: Prevent overwriting files.
|
|
playliststart: Playlist item to start at.
|
|
playlistend: Playlist item to end at.
|
|
matchtitle: Download only matching titles.
|
|
rejecttitle: Reject downloads for matching titles.
|
|
logtostderr: Log messages to stderr instead of stdout.
|
|
writedescription: Write the video description to a .description file
|
|
writeinfojson: Write the video description to a .info.json file
|
|
writeannotations: Write the video annotations to a .annotations.xml file
|
|
writethumbnail: Write the thumbnail image to a file
|
|
writesubtitles: Write the video subtitles to a file
|
|
writeautomaticsub: Write the automatic subtitles to a file
|
|
allsubtitles: Downloads all the subtitles of the video
|
|
(requires writesubtitles or writeautomaticsub)
|
|
listsubtitles: Lists all available subtitles for the video
|
|
subtitlesformat: Subtitle format [srt/sbv/vtt] (default=srt)
|
|
subtitleslangs: List of languages of the subtitles to download
|
|
keepvideo: Keep the video file after post-processing

None to disable filesystem cache.

downloadarchive: File name of a file where all downloads are recorded.
|
|
Videos already present in the file are not downloaded
|
|
again.
|
|
|
|
The following parameters are not used by YoutubeDL itself, they are used by
