"""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".
+ options instead.
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.
- 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.
ratelimit: Download speed limit, in bytes/sec.
- nooverwrites: Prevent overwriting files.
retries: Number of times to retry for HTTP error 5xx
buffersize: Size of download buffer in bytes.
noresizebuffer: Do not automatically resize the download buffer.
continuedl: Try to continue downloads if possible.
noprogress: Do not print the progress bar.
- 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.
consoletitle: Display progress in console window's titlebar.
nopart: Do not use temporary .part files.
updatetime: Use the Last-modified header to set output file timestamps.
- writedescription: Write the video description to a .description file
- writeinfojson: Write the video description to a .info.json file
- writesubtitles: Write the video subtitles to a .srt file
- subtitleslang: Language of the subtitles to download
test: Download only first bytes to test the downloader.
+ min_filesize: Skip files smaller than this size
+ max_filesize: Skip files larger than this size
