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. verbose: Print additional info to stdout. quiet: Do not print messages to stdout. no_warnings: Do not print out anything for warnings. 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. forceduration: Force printing duration. 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. simulate: Do not download the video files. format: Video format code. See options.py for more information. outtmpl: Template for output names. outtmpl_na_placeholder: Placeholder for unavailable meta fields. restrictfilenames: Do not allow "&" and spaces in file names ignoreerrors: Do not stop on download errors. force_generic_extractor: Force downloader to use the generic extractor nooverwrites: Prevent overwriting files. playliststart: Playlist item to start at. playlistend: Playlist item to end at. playlist_items: Specific indices of playlist to download. playlistreverse: Download playlist items in reverse order. playlistrandom: Download playlist items in random order. matchtitle: Download only matching titles. rejecttitle: Reject downloads for matching titles. logger: Log messages to a logging.Logger instance. 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 write_all_thumbnails: Write all thumbnail formats to files thumbnailformat: Thumbnail format ID writesubtitles: Write the video subtitles to a file writeautomaticsub: Write the automatically generated 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: The format code for subtitles subtitleslangs: List of languages of the subtitles to download keepvideo: Keep the video file after post-processing daterange: A DateRange object, download only if the upload_date is in the range. skip_download: Skip the actual download of the video file cachedir: Location of the cache files in the filesystem. False to disable filesystem cache. noplaylist: Download single video instead of a playlist if in doubt. age_limit: An integer representing the user's age in years. Unsuitable videos for the given age are skipped. min_views: An integer representing the minimum view count the video must have in order to not be skipped. Videos without view count information are always downloaded. None for no limit. max_views: An integer representing the maximum view count. Videos that are more popular than that are not downloaded. Videos without view count information are always downloaded. None for no limit. download_archive: File name of a file where all downloads are recorded. Videos already present in the file are not downloaded again. cookiefile: File name where cookies should be read from and dumped to. nocheckcertificate:Do not verify SSL certificates prefer_insecure: Use HTTP instead of HTTPS to retrieve information. At the moment, this is only supported by YouTube. proxy: URL of the proxy server to use geo_verification_proxy: URL of the proxy to use for IP address verification on geo-restricted sites. socket_timeout: Time to wait for unresponsive hosts, in seconds bidi_workaround: Work around buggy terminals without bidirectional text support, using fridibi debug_printtraffic:Print out sent and received HTTP traffic include_ads: Download ads as well default_search: Prepend this string if an input url is not valid. 'auto' for elaborate guessing encoding: Use this encoding instead of the system-specified. extract_flat: Do not resolve URLs, return the immediate result. Pass in 'in_playlist' to only show this behavior for playlist items. postprocessors: A list of dictionaries, each with an entry * key: The name of the postprocessor. See youtube_dl/postprocessor/__init__.py for a list. as well as any further keyword arguments for the postprocessor. progress_hooks: A list of functions that get called on download progress, with a dictionary with the entries * status: One of "downloading", "error", or "finished". Check this first and ignore unknown values. If status is one of "downloading", or "finished", the following properties may also be present: * filename: The final filename (always present) * tmpfilename: The filename we're currently writing to * downloaded_bytes: Bytes on disk * total_bytes: Size of the whole file, None if unknown * total_bytes_estimate: Guess of the eventual file size, None if unavailable. * elapsed: The number of seconds since download started. * eta: The estimated time in seconds, None if unknown * speed: The download speed in bytes/second, None if unknown * fragment_index: The counter of the currently downloaded video fragment. * fragment_count: The number of fragments (= individual files that will be merged) Progress hooks are guaranteed to be called at least once (with status "finished") if the download is successful. merge_output_format: Extension to use when merging formats. fixup: Automatically correct known faults of the file. One of: - "never": do nothing - "warn": only emit a warning - "detect_or_warn": check whether we can do anything about it, warn otherwise (default) source_address: Client-side IP address to bind to. call_home: Boolean, true iff we are allowed to contact the youtube-dl servers for debugging. sleep_interval: Number of seconds to sleep before each download when used alone or a lower bound of a range for randomized sleep before each download (minimum possible number of seconds to sleep) when used along with max_sleep_interval. max_sleep_interval:Upper bound of a range for randomized sleep before each download (maximum possible number of seconds to sleep). Must only be used along with sleep_interval. Actual sleep time will be a random float from range [sleep_interval; max_sleep_interval]. listformats: Print an overview of available video formats and exit. list_thumbnails: Print a table of all thumbnails and exit. match_filter: A function that gets called with the info_dict of every video. If it returns a message, the video is ignored. If it returns None, the video is downloaded. match_filter_func in utils.py is one example for this. no_color: Do not emit color codes in output. geo_bypass: Bypass geographic restriction via faking X-Forwarded-For HTTP header geo_bypass_country: Two-letter ISO 3166-2 country code that will be used for explicit geographic restriction bypassing via faking X-Forwarded-For HTTP header geo_bypass_ip_block: IP range in CIDR notation that will be used similarly to geo_bypass_country The following options determine which downloader is picked: external_downloader: Executable of the external downloader to call. None or unset for standard (built-in) downloader. hls_prefer_native: Use the native HLS downloader instead of ffmpeg/avconv if True, otherwise use ffmpeg/avconv if False, otherwise use downloader suggested by extractor if None. The following parameters are not used by YoutubeDL itself, they are used by the downloader (see youtube_dl/downloader/common.py): nopart, updatetime, buffersize, ratelimit, min_filesize, max_filesize, test, noresizebuffer, retries, continuedl, noprogress, consoletitle, xattr_set_filesize, external_downloader_args, hls_use_mpegts, http_chunk_size. The following options are used by the post processors: prefer_ffmpeg: If False, use avconv instead of ffmpeg if both are available, otherwise prefer ffmpeg. ffmpeg_location: Location of the ffmpeg/avconv binary; either the path to the binary or its containing directory. postprocessor_args: A list of additional command-line arguments for the postprocessor. The following options are used by the Youtube extractor: youtube_include_dash_manifest: If True (default), DASH manifests and related data will be downloaded and processed by extractor. You can reduce network I/O by disabling it if you don't care about DASH.
