"""File Downloader class.
|
||||
|
||||
File downloader 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, file downloader objects have a method that allows
|
||||
InfoExtractors to be registered in a given order. When it is passed
|
||||
a URL, the file downloader 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
|
||||
asks the FileDownloader to process the video information, possibly
|
||||
downloading the video.
|
||||
actual video file and writing it to disk.
|
||||
|
||||
File downloaders 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 FileDownloader also
|
||||
registers itself as the downloader in charge for the InfoExtractors
|
||||
that are added to it, so this is a "mutual registration".

|
||||
|
||||
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.
|
||||
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
|
||||
writethumbnail: Write the thumbnail image to a file
|
||||
writesubtitles: Write the video subtitles to a file
|

allsubtitles: Downloads all the subtitles of the video
|

listsubtitles: Lists all available subtitles for the video
