# DESCRIPTION
2011-08-05 23:14:13 +00:00
**youtube-dl** is a small command-line program to download videos from
YouTube.com and a few more sites. It requires the Python interpreter, version
2014-11-26 12:08:42 +00:00
2.6, 2.7, or 3.2+, and it is not platform specific. It should work on
2013-01-10 22:20:26 +00:00
your Unix box, on Windows or on Mac OS X. It is released to the public domain,
2011-08-05 23:14:13 +00:00
which means you can modify it, redistribute it or use it however you like.

# CONFIGURATION
2016-05-12 14:48:12 +00:00
You can configure youtube-dl by placing any supported command line option to a configuration file. On Linux and OS X, 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`.
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:
```
-x
--no-mtime
--proxy 127.0.0.1:3128
-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`.
2015-12-10 12:45:53 +00:00
You can use `--ignore-config` if you want to disable the 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](http://stackoverflow.com/tags/.netrc/info) on per extractor basis. For that you will need to create a`.netrc` file in your `$HOME` and restrict permissions to read/write by you only:
```
touch $HOME/.netrc
chmod a-rwx,u+rw $HOME/.netrc
```
After that you can add credentials for extractor in the following format, where *extractor* is the name of extractor in lowercase:
```
machine <extractor> login <login> password <password>
```
For example:
```
machine youtube login myaccount@gmail.com password my_youtube_password
machine twitch login my_twitch_account_name password my_twitch_password
```
2015-12-10 12:45:53 +00:00
To activate authentication with the `.netrc` file you should pass `--netrc` to youtube-dl or place it in the [configuration file](#configuration).
On Windows you may also need to setup the `%HOME%` environment variable manually.
# OUTPUT TEMPLATE
The `-o` option allows users to indicate a template for the output file names.
**tl;dr:** [navigate me to examples](#output-template-examples).
The basic usage is not to set any template arguments when downloading a single file, like in `youtube-dl -o funny_video.flv "http://some/video"`. However, it may contain special sequences that will be replaced when downloading each video. The special sequences have the format `%(NAME)s`. To clarify, that is a percent symbol followed by a name in parentheses, followed by a lowercase S. Allowed names are:
- `id`: Video identifier
- `title`: Video title
- `url`: Video URL
- `ext`: Video filename extension
- `alt_title`: A secondary title of the video
- `display_id`: An alternative identifier for the video
- `uploader`: Full name of the video uploader
- `license`: License name the video is licensed under
2016-05-02 15:32:57 +00:00
- `creator`: The creator of the video
- `release_date`: The date (YYYYMMDD) when the video was released
- `timestamp`: UNIX timestamp of the moment the video became available
- `upload_date`: Video upload date (YYYYMMDD)
- `uploader_id`: Nickname or id of the video uploader
- `location`: Physical location where the video was filmed
- `duration`: Length of the video in seconds
- `view_count`: How many users have watched the video on the platform
- `like_count`: Number of positive ratings of the video
- `dislike_count`: Number of negative ratings of the video
- `repost_count`: Number of reposts of the video
- `average_rating`: Average rating give by users, the scale used depends on the webpage
- `comment_count`: Number of comments on the video
- `age_limit`: Age restriction for the video (years)
- `format`: A human-readable description of the format
- `format_id`: Format code specified by `--format`
- `format_note`: Additional info about the format
- `width`: Width of the video
- `height`: Height of the video
- `resolution`: Textual description of width and height
- `tbr`: Average bitrate of audio and video in KBit/s
- `abr`: Average audio bitrate in KBit/s
- `acodec`: Name of the audio codec in use
- `asr`: Audio sampling rate in Hertz
- `vbr`: Average video bitrate in KBit/s
- `fps`: Frame rate
- `vcodec`: Name of the video codec in use
- `container`: Name of the container format
- `filesize`: The number of bytes, if known in advance
- `filesize_approx`: An estimate for the number of bytes
- `protocol`: The protocol that will be used for the actual download
- `extractor`: Name of the extractor
- `extractor_key`: Key name of the extractor
- `epoch`: Unix epoch when creating the file
- `autonumber`: Five-digit number that will be increased with each download, starting at zero
- `playlist`: Name or id of the playlist that contains the video
- `playlist_index`: Index of the video in the playlist padded with leading zeros according to the total length of the playlist
2016-02-06 16:36:30 +00:00
Available for the video that belongs to some logical chapter or section:
- `chapter`: Name or title of the chapter the video belongs to
- `chapter_number`: Number of the chapter the video belongs to
- `chapter_id`: Id of the chapter the video belongs to
Available for the video that is an episode of some series or programme:
- `series`: Title of the series or programme the video episode belongs to
- `season`: Title of the season the video episode belongs to
- `season_number`: Number of the season the video episode belongs to
- `season_id`: Id of the season the video episode belongs to
- `episode`: Title of the video episode
- `episode_number`: Number of the video episode within a season
- `episode_id`: Id of the video episode
Available for the media that is a track or a part of a music album:
- `track`: Title of the track
- `track_number`: Number of the track within an album or a disc
- `track_id`: Id of the track
- `artist`: Artist(s) of the track
- `genre`: Genre(s) of the track

- `album_type`: Type of the album
- `album_artist`: List of all artists appeared on the album
- `disc_number`: Number of the disc or other physical medium the track belongs to
- `release_year`: Year (YYYY) when the album was released
Each aforementioned sequence when referenced in 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 particular extractor, such sequences will be replaced with `NA`.
For example for `-o %(title)s-%(id)s.%(ext)s` and 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.
Output template can also contain arbitrary hierarchical path, e.g. `-o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s'` that will result in downloading each video in a directory corresponding to this path template. Any missing directory will be automatically created for you.
To specify percent literal in 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:
#### Output template examples
Note on Windows you may need to use double quotes instead of single.
```bash
$ youtube-dl --get-filename -o '%(title)s.%(ext)s' BaW_jenozKc
youtube-dl test video ''_ä↭𝕐.mp4 # All kinds of weird characters
$ youtube-dl --get-filename -o '%(title)s.%(ext)s' BaW_jenozKc --restrict-filenames
youtube-dl_test_video_.mp4 # A simple file name
# Download YouTube playlist videos in separate directory indexed by video order in a playlist
$ youtube-dl -o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s' https://www.youtube.com/playlist?list=PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re
# Download all playlists of YouTube channel/user keeping each playlist in separate directory:
$ youtube-dl -o '%(uploader)s/%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s' https://www.youtube.com/user/TheLinuxFoundation/playlists
# Download Udemy course keeping each chapter in separate directory under MyVideos directory in your home
$ youtube-dl -u user -p password -o '~/MyVideos/%(playlist)s/%(chapter_number)s - %(chapter)s/%(title)s.%(ext)s' https://www.udemy.com/java-tutorial/
# Download entire series season keeping each series and each season in separate directory under C:/MyVideos
$ youtube-dl -o "C:/MyVideos/%(series)s/%(season_number)s - %(season)s/%(episode_number)s - %(episode)s.%(ext)s" http://videomore.ru/kino_v_detalayah/5_sezon/367617
# Stream the video being downloaded to stdout
$ youtube-dl -o - BaW_jenozKc
```
# FORMAT SELECTION
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](#format-selection-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 best quality format of particular file extension served as a single file, e.g. `-f webm` will download best quality format with `webm` extension served as a single file.
You can also use special names to select particular edge case format:
- `best`: Select best quality format represented by single file with video and audio
- `worst`: Select worst quality format represented by single file with video and audio
- `bestvideo`: Select best quality video only format (e.g. DASH video), may not be available
- `worstvideo`: Select worst quality video only format, may not be available
- `bestaudio`: Select best quality audio only format, may not be available
- `worstaudio`: Select worst quality audio only format, may not be available
For example, to download 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 comma as a separator, e.g. `-f 22,17,18` will download all these three formats, of course if they are available. Or more sophisticated example combined with 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 advance
- `width`: Width of the video, if known
- `height`: Height of the video, if known
- `tbr`: Average bitrate of audio and video in KBit/s
- `abr`: Average audio bitrate in KBit/s
- `vbr`: Average video bitrate in KBit/s
- `asr`: Audio sampling rate in Hertz
- `fps`: Frame rate
Also filtering work for comparisons `=` (equals), `!=` (not equals), `^=` (begins with), `$=` (ends with), `*=` (contains) and following string meta fields:
- `ext`: File extension
- `acodec`: Name of the audio codec in use
- `vcodec`: Name of the video codec in use
- `container`: Name of the container format
- `protocol`: The protocol that will be used for the actual download, lower-case. `http`, `https`, `rtsp`, `rtmp`, `rtmpe`, `m3u8`, or `m3u8_native`
- `format_id`: A short description of the format
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 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 best video only format, 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 default format selection (see [#5447](https://github.com/rg3/youtube-dl/issues/5447), [#5456](https://github.com/rg3/youtube-dl/issues/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.
2015-12-10 12:45:53 +00:00
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](#configuration) in order not to type it every time you run youtube-dl.
#### Format selection examples
Note on Windows you may need to use double quotes instead of single.
```bash
# 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 not better that 480p
$ youtube-dl -f 'bestvideo[height<=480]+bestaudio/best[height<=480]'
# Download best video only format but no bigger that 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]'
```
# VIDEO SELECTION
Videos can be filtered by their upload date using the options `--date`, `--datebefore` or `--dateafter`. They accept dates in two formats:
- Absolute dates: Dates in the format `YYYYMMDD`.
- Relative dates: Dates in the format `(now|today)[+-][0-9](day|week|month|year)(s)?`
Examples:
```bash
# Download only the videos uploaded in the last 6 months
$ youtube-dl --dateafter now-6months
2014-02-17 13:58:39 +00:00
# Download only the videos uploaded on January 1, 1970
$ youtube-dl --date 19700101
2014-02-17 13:58:39 +00:00
$ # Download only the videos uploaded in the 200x decade
$ youtube-dl --dateafter 20000101 --datebefore 20091231
```
# FAQ
2011-09-04 09:41:54 +00:00
### How do I update youtube-dl?
If you've followed [our manual installation instructions](http://rg3.github.io/youtube-dl/download.html), you can simply run `youtube-dl -U` (or, on Linux, `sudo youtube-dl -U`).
If you have used pip, a simple `sudo pip install -U youtube-dl` is sufficient to update.
2015-12-10 12:45:53 +00:00
If you have installed youtube-dl using a package manager like *apt-get* or *yum*, use the standard system update mechanism to update. Note that distribution packages are often outdated. As a rule of thumb, youtube-dl releases at least once a month, and often weekly or even daily. Simply go to http://yt-dl.org/ to find out the current version. Unfortunately, there is nothing we youtube-dl developers can do if your distribution serves a really outdated version. You can (and should) complain to your distribution in their bugtracker or support forum.
As a last resort, you can also uninstall the version installed by your package manager and follow our manual installation instructions. For that, remove the distribution's package, with a line like
sudo apt-get remove -y youtube-dl
Afterwards, simply follow [our manual installation instructions](http://rg3.github.io/youtube-dl/download.html):
```
sudo wget https://yt-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+x /usr/local/bin/youtube-dl
hash -r
```
Again, from then on you'll be able to update with `sudo youtube-dl -U`.
### I'm getting an error `Unable to extract OpenGraph title` on YouTube playlists
2015-12-10 12:45:53 +00:00
YouTube changed their playlist format in March 2014 and later on, so you'll need at least youtube-dl 2014.07.25 to download all YouTube videos.
2015-12-10 12:45:53 +00:00
If you have installed youtube-dl with a package manager, pip, setup.py or a tarball, please use that to update. Note that Ubuntu packages do not seem to get updated anymore. Since we are not affiliated with Ubuntu, there is little we can do. Feel free to [report bugs](https://bugs.launchpad.net/ubuntu/+source/youtube-dl/+filebug) to the [Ubuntu packaging guys](mailto:ubuntu-motu@lists.ubuntu.com?subject=outdated%20version%20of%20youtube-dl) - all they have to do is update the package to a somewhat recent version. See above for a way to update.
### I'm getting an error when trying to use output template: `error: using output template conflicts with using title, video ID or auto number`
Make sure you are not using `-o` with any of these options `-t`, `--title`, `--id`, `-A` or `--auto-number` set in command line or in a configuration file. Remove the latter if any.
2015-04-25 13:14:16 +00:00
### Do I always have to pass `-citw`?
2015-12-10 12:45:53 +00:00
By default, youtube-dl intends to have the best options (incidentally, if you have a convincing case that these should be different, [please file an issue where you explain that](https://yt-dl.org/bug)). Therefore, it is unnecessary and sometimes harmful to copy long option strings from webpages. In particular, the only option out of `-citw` that is regularly useful is `-i`.
2015-10-05 20:30:05 +00:00
### Can you please put the `-b` option back?
2011-09-04 09:41:54 +00:00
2015-12-10 12:45:53 +00:00
Most people asking this question are not aware that youtube-dl now defaults to downloading the highest available quality as reported by YouTube, which will be 1080p or 720p in some cases, so you no longer need the `-b` option. For some specific videos, maybe YouTube does not report them to be available in a specific high quality format you're interested in. In that case, simply request it with the `-f` option and youtube-dl will try to download it.

### I get HTTP error 402 when trying to download a video. What's this?
2011-09-04 09:41:54 +00:00
2015-12-10 12:45:53 +00:00
Apparently YouTube requires you to pass a CAPTCHA test if you download too much. We're [considering to provide a way to let you solve the CAPTCHA](https://github.com/rg3/youtube-dl/issues/154), but at the moment, your best course of action is pointing a webbrowser to the youtube URL, solving the CAPTCHA, and restart youtube-dl.
2011-09-04 09:41:54 +00:00
### Do I need any other programs?
2015-12-10 12:45:53 +00:00
youtube-dl works fine on its own on most sites. However, if you want to convert video/audio, you'll need [avconv](https://libav.org/) or [ffmpeg](https://www.ffmpeg.org/). On some sites - most notably YouTube - videos can be retrieved in a higher quality format without sound. youtube-dl will detect whether avconv/ffmpeg is present and automatically pick the best option.
Videos or video formats streamed via RTMP protocol can only be downloaded when [rtmpdump](https://rtmpdump.mplayerhq.hu/) is installed. Downloading MMS and RTSP videos requires either [mplayer](http://mplayerhq.hu/) or [mpv](https://mpv.io/) to be installed.
2011-09-04 09:41:54 +00:00
### I have downloaded a video but how can I play it?
2016-04-26 18:22:08 +00:00
Once the video is fully downloaded, use any video player, such as [mpv](https://mpv.io/), [vlc](http://www.videolan.org) or [mplayer](http://www.mplayerhq.hu/).
2011-09-04 09:41:54 +00:00

### I extracted a video URL with `-g`, but it does not play on another machine / in my webbrowser.
2011-09-04 09:41:54 +00:00
2015-12-10 12:45:53 +00:00
It depends a lot on the service. In many cases, requests for the video (to download/play it) must come from the same IP address and with the same cookies. Use the `--cookies` option to write the required cookies into a file, and advise your downloader to read cookies from that file. Some sites also require a common user agent to be used, use `--dump-user-agent` to see the one in use by youtube-dl.
It may be beneficial to use IPv6; in some cases, the restrictions are only applied to IPv4. Some services (sometimes only for a subset of videos) do not restrict the video URL by IP address, cookie, or user-agent, but these are the exception rather than the rule.
2015-10-05 20:30:05 +00:00
Please bear in mind that some URL protocols are **not** supported by browsers out of the box, including RTMP. If you are using `-g`, your own downloader must support these as well.
2015-12-10 12:45:53 +00:00
If you want to play the video on a machine that is not running youtube-dl, you can relay the video content from the machine that runs youtube-dl. You can use `-o -` to let youtube-dl stream a video to stdout, or simply allow the player to download the files written by youtube-dl in turn.
