- Created this fork
youtube-dl currently have over 700 open pull requests and 3100 open issues. The project has very few maintainers and considering their very strict policies on merges, it makes sense that they are not able to look into and fix this massive amount of backlog. However, there are some of these pull requests that I really want to use. So I created this fork and am pulling all the things I need into it. If anyone else wants to use this fork, feel free to do so. I personally use youtube-dl quite a lot, so expect the fork to be frequently updated.
I am not accepting any feature requests. You probably better off making the request on the original repository or youtube-dlc.
If you already have the code, it's a different story. Make the pull request, and I will merge it as long as it doesn't break anything else.
I don't plan on making any releases. If anyone wants to create and maintain releases for this fork, please contact me.
You can clone / download this repository and run it with python youtube_dl/__main__.py <args>. Alternatively, you can install the fork using pip install --upgrade https://github.com/pukkandan/youtube-dl/archive/master.zip and run it with python -m youtube_dl <args>.
In order to update, simply repeat the process.
youtube-dl is a command-line program to download videos from YouTube.com and a few more sites. It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is not platform specific. It should work on your Unix box, on Windows or on macOS. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.
youtube-dl [OPTIONS] [--] URL [URL...]
-h, --help Print this help text and exit
--version Print program version and exit
-U, --update (Doesn't work since there is no release)
Update this program to latest version. Make
sure that you have sufficient permissions
(run with sudo if needed)
-i, --ignore-errors Continue on download errors, for example to
skip unavailable videos in a playlist (default)

example "gvsearch2:" downloads two videos
from google videos for youtube-dl "large
apple". Use the value "auto" to let
youtube-dl guess ("auto_warning" to emit a
warning when guessing). "error" just throws
an error. The default value "fixup_error"
repairs broken URLs, but emits an error if
this is not possible instead of searching.
--ignore-config, --no-config Do not read configuration files. When given

> 12", also works with >=, <, <=, !=, =) to
compare against a number, key = 'LITERAL'
(like "uploader = 'Mike Smith'", also works
with !=) to match against a string literal
and & to require multiple matches. Values
which are not known are excluded unless you
put a question mark (?) after the operator.
For example, to only match videos that have
been liked more than 100 times and disliked

Note that the OS caches the URL based on the file path.
-S, --format-sort SORTORDER Sort the formats by the fields given.
Default order: avoid_bad, has_video, extractor, language,
height, width, proto, fps, codec, filesize, filesize_approx,
tbr, vbr, has_audio, abr, audio_codec, quality, source, format_id.
Prefix the field (except format_id) by a + to
perform the sort in reverse. Suffix the field with
:NUMBER to give highest preference to "NUMBER".
Examples: 1)
"-f bestvideo --format-sort +height:720,fps,+filesize"
gets the video with the smallest filesize with the
largest fps with the smallest height>=720 (or
largest height available if there is no such format).
2) "-f bestvideo --format-sort height:720,tbr" gets the
video with largest bitrate with the largest height<=720
(or smallest height available if there is no such format)
--format-sort-force User specified sort order takes priority even over
avoid_bad, has_video, extractor and language.
These fields normally filter out the undesirable formats.
So use this option with caution.

You can configure youtube-dl by placing any supported command line option to a configuration file. On Linux and macOS, the system wide configuration file is located at /etc/youtube-dl.conf and the user wide configuration file at ~/.config/youtube-dl/config. On Windows, the user wide configuration file locations are %APPDATA%\youtube-dl\config.txt or C:\Users\<user name>\youtube-dl.conf. Note that by default configuration file may not exist so you may need to create it yourself.
For example, with the following configuration file youtube-dl will always extract the audio, not copy the mtime, use a proxy and save all videos under Movies directory in your home directory:
# Lines starting with # are comments
# Always extract audio
-x
# Do not copy the mtime
--no-mtime
# Use this proxy
--proxy 127.0.0.1:3128
# Save all videos under Movies directory in your home directory
-o ~/Movies/%(title)s.%(ext)s
Note that options in configuration file are just the same options aka switches used in regular command line calls thus there must be no whitespace after - or --, e.g. -o or --proxy but not - o or -- proxy.
You can use --ignore-config if you want to disable the configuration file for a particular youtube-dl run.
You can also use --config-location if you want to use custom configuration file for a particular youtube-dl run.
You may also want to configure automatic credentials storage for extractors that support authentication (by providing login and password with --username and --password) in order not to pass credentials as command line arguments on every youtube-dl execution and prevent tracking plain text passwords in the shell command history. You can achieve this using a .netrc file on a per extractor basis. For that you will need to create a .netrc file in your $HOME and restrict permissions to read/write by only you:
touch $HOME/.netrc
chmod a-rwx,u+rw $HOME/.netrc
After that you can add credentials for an extractor in the following format, where extractor is the name of the extractor in lowercase:
machine <extractor> login <login> password <password>
For example:
machine youtube login [email protected] password my_youtube_password
machine twitch login my_twitch_account_name password my_twitch_password
To activate authentication with the .netrc file you should pass --netrc to youtube-dl or place it in the configuration file.
On Windows you may also need to setup the %HOME% environment variable manually. For example:
set HOME=%USERPROFILE%
The -o option allows users to indicate a template for the output file names.
tl;dr: navigate me to examples.
The basic usage is not to set any template arguments when downloading a single file, like in youtube-dl -o funny_video.flv "https://some/video". However, it may contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to python string formatting operations. For example, %(NAME)s or %(NAME)05d. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations. Allowed names along with sequence type are:
id(string): Video identifiertitle(string): Video titleurl(string): Video URLext(string): Video filename extensionalt_title(string): A secondary title of the videodisplay_id(string): An alternative identifier for the videouploader(string): Full name of the video uploaderlicense(string): License name the video is licensed undercreator(string): The creator of the videorelease_date(string): The date (YYYYMMDD) when the video was releasedtimestamp(numeric): UNIX timestamp of the moment the video became availableupload_date(string): Video upload date (YYYYMMDD)uploader_id(string): Nickname or id of the video uploaderchannel(string): Full name of the channel the video is uploaded onchannel_id(string): Id of the channellocation(string): Physical location where the video was filmedduration(numeric): Length of the video in secondsview_count(numeric): How many users have watched the video on the platformlike_count(numeric): Number of positive ratings of the videodislike_count(numeric): Number of negative ratings of the videorepost_count(numeric): Number of reposts of the videoaverage_rating(numeric): Average rating give by users, the scale used depends on the webpagecomment_count(numeric): Number of comments on the videoage_limit(numeric): Age restriction for the video (years)is_live(boolean): Whether this video is a live stream or a fixed-length videostart_time(numeric): Time in seconds where the reproduction should start, as specified in the URLend_time(numeric): Time in seconds where the reproduction should end, as specified in the URLformat(string): A human-readable description of the formatformat_id(string): Format code specified by--formatformat_note(string): Additional info about the formatwidth(numeric): Width of the videoheight(numeric): Height of the videoresolution(string): Textual description of width and heighttbr(numeric): Average bitrate of audio and video in KBit/sabr(numeric): Average audio bitrate in KBit/sacodec(string): Name of the audio codec in useasr(numeric): Audio sampling rate in Hertzvbr(numeric): Average video bitrate in KBit/sfps(numeric): Frame ratevcodec(string): Name of the video codec in usecontainer(string): Name of the container formatfilesize(numeric): The number of bytes, if known in advancefilesize_approx(numeric): An estimate for the number of bytesprotocol(string): The protocol that will be used for the actual downloadextractor(string): Name of the extractorextractor_key(string): Key name of the extractorepoch(numeric): Unix epoch when creating the fileautonumber(numeric): Five-digit number that will be increased with each download, starting at zeroplaylist(string): Name or id of the playlist that contains the videoplaylist_index(numeric): Index of the video in the playlist padded with leading zeros according to the total length of the playlistplaylist_id(string): Playlist identifierplaylist_title(string): Playlist titleplaylist_uploader(string): Full name of the playlist uploaderplaylist_uploader_id(string): Nickname or id of the playlist uploader

Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. Note that some of the sequences are not guaranteed to be present since they depend on the metadata obtained by a particular extractor. Such sequences will be replaced with NA.
For example for -o %(title)s-%(id)s.%(ext)s and an mp4 video with title youtube-dl test video and id BaW_jenozKcj, this will result in a youtube-dl test video-BaW_jenozKcj.mp4 file created in the current directory.
For numeric sequences you can use numeric related formatting, for example, %(view_count)05d will result in a string with view count padded with zeros up to 5 characters, like in 00042.
Output templates can also contain arbitrary hierarchical path, e.g. -o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s' which will result in downloading each video in a directory corresponding to this path template. Any missing directory will be automatically created for you.
To use percent literals in an output template use %%. To output to stdout use -o -.
The current default template is %(title)s-%(id)s.%(ext)s.
In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the --restrict-filenames flag to get a shorter title:
If you are using an output template inside a Windows batch file then you must escape plain percent characters (%) by doubling, so that -o "%(title)s-%(id)s.%(ext)s" should become -o "%%(title)s-%%(id)s.%%(ext)s". However you should not touch %'s that are not plain characters, e.g. environment variables for expansion should stay intact: -o "C:\%HOMEPATH%\Desktop\%%(title)s.%%(ext)s".
Note that on Windows you may need to use double quotes instead of single.

$ youtube-dl -o - BaW_jenozKcNote: Also see --format-sort. It significantly simplifies complex format selections.
TODO: Rewrite with examples using --format-sort
By default youtube-dl tries to download the best available quality, i.e. if you want the best quality you don't need to pass any special options, youtube-dl will guess it for you by default.
But sometimes you may want to download in a different format, for example when you are on a slow or intermittent connection. The key mechanism for achieving this is so-called format selection based on which you can explicitly specify desired format, select formats based on some criterion or criteria, setup precedence and much more.
The general syntax for format selection is --format FORMAT or shorter -f FORMAT where FORMAT is a selector expression, i.e. an expression that describes format or formats you would like to download.
tl;dr: navigate me to examples.
The simplest case is requesting a specific format, for example with -f 22 you can download the format with format code equal to 22. You can get the list of available format codes for particular video using --list-formats or -F. Note that these format codes are extractor specific.
You can also use a file extension (currently 3gp, aac, flv, m4a, mp3, mp4, ogg, wav, webm are supported) to download the best quality format of a particular file extension served as a single file, e.g. -f webm will download the best quality format with the webm extension served as a single file.
You can also use special names to select particular edge case formats:
best: Select the best quality format represented by a single file with video and audio.worst: Select the worst quality format represented by a single file with video and audio.bestvideo: Select the best quality video-only format (e.g. DASH video). May not be available.worstvideo: Select the worst quality video-only format. May not be available.bestaudio: Select the best quality audio only-format. May not be available.worstaudio: Select the worst quality audio only-format. May not be available.
For example, to download the worst quality video-only format you can use -f worstvideo.
If you want to download multiple videos and they don't have the same formats available, you can specify the order of preference using slashes. Note that slash is left-associative, i.e. formats on the left hand side are preferred, for example -f 22/17/18 will download format 22 if it's available, otherwise it will download format 17 if it's available, otherwise it will download format 18 if it's available, otherwise it will complain that no suitable formats are available for download.
If you want to download several formats of the same video use a comma as a separator, e.g. -f 22,17,18 will download all these three formats, of course if they are available. Or a more sophisticated example combined with the precedence feature: -f 136/137/mp4/bestvideo,140/m4a/bestaudio.
You can also filter the video formats by putting a condition in brackets, as in -f "best[height=720]" (or -f "[filesize>10M]").
The following numeric meta fields can be used with comparisons <, <=, >, >=, = (equals), != (not equals):
filesize: The number of bytes, if known in advancewidth: Width of the video, if knownheight: Height of the video, if knowntbr: Average bitrate of audio and video in KBit/sabr: Average audio bitrate in KBit/svbr: Average video bitrate in KBit/sasr: Audio sampling rate in Hertzfps: Frame rate
Also filtering work for comparisons = (equals), ^= (starts with), $= (ends with), *= (contains) and following string meta fields:
ext: File extensionacodec: Name of the audio codec in usevcodec: Name of the video codec in usecontainer: Name of the container formatprotocol: The protocol that will be used for the actual download, lower-case (http,https,rtsp,rtmp,rtmpe,mms,f4m,ism,http_dash_segments,m3u8, orm3u8_native)format_id: A short description of the format
Any string comparison may be prefixed with negation ! in order to produce an opposite comparison, e.g. !*= (does not contain).
Note that none of the aforementioned meta fields are guaranteed to be present since this solely depends on the metadata obtained by particular extractor, i.e. the metadata offered by the video hoster.
Formats for which the value is not known are excluded unless you put a question mark (?) after the operator. You can combine format filters, so -f "[height <=? 720][tbr>500]" selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 KBit/s.
You can merge the video and audio of two formats into a single file using -f <video-format>+<audio-format> (requires ffmpeg or avconv installed), for example -f bestvideo+bestaudio will download the best video-only format, the best audio-only format and mux them together with ffmpeg/avconv.
Format selectors can also be grouped using parentheses, for example if you want to download the best mp4 and webm formats with a height lower than 480 you can use -f '(mp4,webm)[height<480]'.
Since the end of April 2015 and version 2015.04.26, youtube-dl uses -f bestvideo+bestaudio/best as the default format selection (see #5447, #5456). If ffmpeg or avconv are installed this results in downloading bestvideo and bestaudio separately and muxing them together into a single file giving the best overall quality available. Otherwise it falls back to best and results in downloading the best available quality served as a single file. best is also needed for videos that don't come from YouTube because they don't provide the audio and video in two different files. If you want to only download some DASH formats (for example if you are not interested in getting videos with a resolution higher than 1080p), you can add -f bestvideo[height<=?1080]+bestaudio/best to your configuration file. Note that if you use youtube-dl to stream to stdout (and most likely to pipe it to your media player then), i.e. you explicitly specify output template as -o -, youtube-dl still uses -f best format selection in order to start content delivery immediately to your player and not to wait until bestvideo and bestaudio are downloaded and muxed.
If you want to preserve the old format selection behavior (prior to youtube-dl 2015.04.26), i.e. you want to download the best available quality media served as a single file, you should explicitly specify your choice with -f best. You may want to add it to the configuration file in order not to type it every time you run youtube-dl.
Note that on Windows you may need to use double quotes instead of single.
# Download best mp4 format available or any other best if no mp4 available
$ youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best'
# Download best format available but no better than 480p
$ youtube-dl -f 'bestvideo[height<=480]+bestaudio/best[height<=480]'
# Download best video only format but no bigger than 50 MB
$ youtube-dl -f 'best[filesize<50M]'
# Download best format available via direct link over HTTP/HTTPS protocol
$ youtube-dl -f '(bestvideo+bestaudio/best)[protocol^=http]'
# Download the best video format and the best audio format without merging them
$ youtube-dl -f 'bestvideo,bestaudio' -o '%(title)s.f%(format_id)s.%(ext)s'Note that in the last example, an output template is recommended as bestvideo and bestaudio may have the same file name.
