21 class YoutubeDL(object):
24 YoutubeDL objects are the ones responsible of downloading the
25 actual video file and writing it to disk if the user has requested
26 it, among some other tasks. In most cases there should be one per
27 program. As, given a video URL, the downloader doesn't know how to
28 extract all the needed information, task that InfoExtractors do, it
29 has to pass the URL to one of them.
31 For this, YoutubeDL objects have a method that allows
32 InfoExtractors to be registered in a given order. When it is passed
33 a URL, the YoutubeDL object handles it to the first InfoExtractor it
34 finds that reports being able to handle it. The InfoExtractor extracts
35 all the information about the video or videos the URL refers to, and
36 YoutubeDL process the extracted information, possibly using a File
37 Downloader to download the video.
39 YoutubeDL objects accept a lot of parameters. In order not to saturate
40 the object constructor with arguments, it receives a dictionary of
41 options instead. These options are available through the params
42 attribute for the InfoExtractors to use. The YoutubeDL also
43 registers itself as the downloader in charge for the InfoExtractors
44 that are added to it, so this is a "mutual registration".
48 username: Username for authentication purposes.
49 password: Password for authentication purposes.
50 videopassword: Password for acces a video.
51 usenetrc: Use netrc for authentication instead.
52 verbose: Print additional info to stdout.
53 quiet: Do not print messages to stdout.
54 forceurl: Force printing final URL.
55 forcetitle: Force printing title.
56 forceid: Force printing ID.
57 forcethumbnail: Force printing thumbnail URL.
58 forcedescription: Force printing description.
59 forcefilename: Force printing final filename.
60 simulate: Do not download the video files.
61 format: Video format code.
62 format_limit: Highest quality format to try.
63 outtmpl: Template for output names.
64 restrictfilenames: Do not allow "&" and spaces in file names
65 ignoreerrors: Do not stop on download errors.
66 nooverwrites: Prevent overwriting files.
67 playliststart: Playlist item to start at.
68 playlistend: Playlist item to end at.
69 matchtitle: Download only matching titles.
70 rejecttitle: Reject downloads for matching titles.
71 logtostderr: Log messages to stderr instead of stdout.
72 writedescription: Write the video description to a .description file
73 writeinfojson: Write the video description to a .info.json file
74 writeannotations: Write the video annotations to a .annotations.xml file
75 writethumbnail: Write the thumbnail image to a file
76 writesubtitles: Write the video subtitles to a file
77 writeautomaticsub: Write the automatic subtitles to a file
78 allsubtitles: Downloads all the subtitles of the video
79 (requires writesubtitles or writeautomaticsub)
80 listsubtitles: Lists all available subtitles for the video
81 subtitlesformat: Subtitle format [srt/sbv/vtt] (default=srt)
82 subtitleslangs: List of languages of the subtitles to download
83 keepvideo: Keep the video file after post-processing
84 daterange: A DateRange object, download only if the upload_date is in the range.
85 skip_download: Skip the actual download of the video file
86 cachedir: Location of the cache files in the filesystem.
87 None to disable filesystem cache.
88 noplaylist: Download single video instead of a playlist if in doubt.
89 age_limit: An integer representing the user's age in years.
90 Unsuitable videos for the given age are skipped.
91 downloadarchive: File name of a file where all downloads are recorded.
92 Videos already present in the file are not downloaded
