NEW FEATURES


The major new features from the latest release of blackjack4494/yt-dlc
are:

-   SPONSKRUB INTEGRATION: You can use SponSkrub to mark/remove sponsor
    sections in youtube videos by utilizing the SponsorBlock API

-   FORMAT SORTING: The default format sorting options have been changed
    so that higher resolution and better codecs will be now preferred
    instead of simply using larger bitrate. Furthermore, you can now
    specify the sort order using -S. This allows for much easier format
    selection that what is possible by simply using --format (examples)

        of content
    -   Youtube search works correctly (ytsearch:, ytsearchdate:) along
        with Search URLs
    -   Redirect channel's home URL automatically to /video to preserve
        the old behaviour
-   NEW EXTRACTORS: AnimeLab, Philo MSO, Rcs, Gedi, bitwave.tv, mildom

-   FIXED EXTRACTORS: archive.org, roosterteeth.com, skyit, instagram,
    itv, SouthparkDe, spreaker, Vlive, tiktok, akamai, ina

-   PLUGIN SUPPORT: Extractors can be loaded from an external file. See
    plugins for details

-   MULTIPLE PATHS: You can give different paths for different types of
    files. You can also set a temporary path where intermediary files
    are downloaded to. See --paths for details

-   PORTABLE CONFIGURATION: Configuration files are automatically loaded
    from the home and root directories. See configuration for details

-   OTHER NEW OPTIONS: --list-formats-as-table, --write-link,
    --force-download-archive, --force-overwrites, --break-on-reject etc

    --version                        Print program version and exit
    -U, --update                     [BROKEN] 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) (Alias: --no-abort-on-error)
    --abort-on-error                 Abort downloading of further videos if an
                                     error occurs (Alias: --no-ignore-errors)
    --dump-user-agent                Display the current browser identification
    --list-extractors                List all supported extractors
    --extractor-descriptions         Output descriptions of all supported
                                     extractors
    --force-generic-extractor        Force extraction to use the generic
                                     extractor
    --default-search PREFIX          Use this prefix for unqualified URLs. For
                                     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

                                     also be used. The parsed parameters replace
                                     existing values. Example: --metadata-from-
                                     title "%(artist)s - %(title)s" matches a
                                     title like "Coldplay - Paradise". Example

SponSkrub (SponsorBlock) Options:

    SponSkrub (https://github.com/pukkandan/SponSkrub) is a utility to
    mark/remove sponsor segments from downloaded YouTube videos using
    SponsorBlock API (https://sponsor.ajay.app)

    --sponskrub                      Use sponskrub to mark sponsored sections.
                                     This is enabled by default if the sponskrub
                                     binary exists (Youtube only)
    --no-sponskrub                   Do not use sponskrub
    --sponskrub-cut                  Cut out the sponsor sections instead of
                                     simply marking them
    --no-sponskrub-cut               Simply mark the sponsor sections, not cut
                                     them out (default)
    --sponskrub-force                Run sponskrub even if the video was already
                                     downloaded
    --no-sponskrub-force             Do not cut out the sponsor sections if the
                                     video was already downloaded (default)
    --sponskrub-location PATH        Location of the sponskrub binary; either
                                     the path to the binary or its containing
                                     directory


Extractor Options:

    --allow-dynamic-mpd              Process dynamic DASH manifests (default)
                                     (Alias: --no-ignore-dynamic-mpd)
    --ignore-dynamic-mpd             Do not process dynamic DASH manifests
                                     (Alias: --no-allow-dynamic-mpd)



CONFIGURATION


You can configure youtube-dlc by placing any supported command line
option to a configuration file. The configuration is loaded from the
following locations:

1.  MAIN CONFIGURATION: The file given by --config-location
2.  PORTABLE CONFIGURATION: yt-dlp.conf or youtube-dlc.conf in the same
    directory as the bundled binary. If you are running from source-code
    (<root dir>/youtube_dlc/__main__.py), the root directory is used
    instead.
3.  HOME CONFIGURATION: yt-dlp.conf or youtube-dlc.conf in the home path
    given by -P "home:<path>", or in the current directory if no such
    path is given
4.  USER CONFIGURATION:
    -   %XDG_CONFIG_HOME%/yt-dlp/config (recommended on Linux/macOS)
    -   %XDG_CONFIG_HOME%/yt-dlp.conf
    -   %APPDATA%/yt-dlp/config (recommended on Windows)
    -   %APPDATA%/yt-dlp/config.txt
    -   ~/yt-dlp.conf
    -   ~/yt-dlp.conf.txt

    If none of these files are found, the search is performed again by
    replacing yt-dlp with youtube-dlc. Note that ~ points to
    C:\Users\<user name> on windows. Also, %XDG_CONFIG_HOME% defaults to
    ~/.config if undefined
5.  SYSTEM CONFIGURATION: /etc/yt-dlp.conf or /etc/youtube-dlc.conf

For example, with the following configuration file youtube-dlc will
always extract the audio, not copy the mtime, use a proxy and save all
videos under YouTube 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 YouTube directory in your home directory
    -o ~/YouTube/%(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 all configuration
files for a particular youtube-dlc run. If --ignore-config is found
inside any configuration file, no further configuration will be loaded.
For example, having the option in the portable configuration file
prevents loading of user and system configurations. Additionally, (for
backward compatibility) if --ignore-config is found inside the system
configuration file, the user configuration is not loaded.

Authentication with .netrc file

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-dlc 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 myaccount@gmail.com 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-dlc 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%



OUTPUT TEMPLATE


The -o option is used to indicate a template for the output file names
while -P option is used to specify the path each type of file should be
saved to.

TL;DR: navigate me to examples.

The basic usage is not to set any template arguments when downloading a
single file, like in
youtube-dlc -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:

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 placeholder value provided with
--output-na-placeholder (NA by default).

For example for -o %(title)s-%(id)s.%(ext)s and an mp4 video with title
youtube-dlc test video and id BaW_jenozKcj, this will result in a
youtube-dlc 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:

Output template and Windows batch files

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".

Output template examples

Note that on Windows you may need to use double quotes instead of
single.

    # Stream the video being downloaded to stdout
    $ youtube-dlc -o - BaW_jenozKc



FORMAT SELECTION


By default, youtube-dlc tries to download the best available quality if
you DON'T pass any options. This is generally equivalent to using
-f bestvideo*+bestaudio/best. However, if multiple audiostreams is
enabled (--audio-multistreams), the default format changes to
-f bestvideo+bestaudio/best. Similarly, if ffmpeg and avconv are
unavailable, or if you use youtube-dlc to stream to stdout (-o -), the
default becomes -f best/bestvideo+bestaudio.

The general syntax for format selection is --f FORMAT (or
--format 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:

-   b*, best*: Select the best quality format irrespective of whether it
    contains video or audio.
-   w*, worst*: Select the worst quality format irrespective of whether
    it contains video or audio.
-   b, best: Select the best quality format that contains both video and
    audio. Equivalent to best*[vcodec!=none][acodec!=none]
-   w, worst: Select the worst quality format that contains both video
    and audio. Equivalent to worst*[vcodec!=none][acodec!=none]
-   bv, bestvideo: Select the best quality video-only format. Equivalent
    to best*[acodec=none]
-   wv, worstvideo: Select the worst quality video-only format.
    Equivalent to worst*[acodec=none]
-   bv*, bestvideo*: Select the best quality format that contains video.
    It may also contain audio. Equivalent to best*[vcodec!=none]
-   wv*, worstvideo*: Select the worst quality format that contains
    video. It may also contain audio. Equivalent to worst*[vcodec!=none]
-   ba, bestaudio: Select the best quality audio-only format. Equivalent
    to best*[vcodec=none]
-   wa, worstaudio: Select the worst quality audio-only format.
    Equivalent to worst*[vcodec=none]
-   ba*, bestaudio*: Select the best quality format that contains audio.
    It may also contain video. Equivalent to best*[acodec!=none]
-   wa*, worstaudio*: Select the worst quality format that contains
    audio. It may also contain video. Equivalent to worst*[acodec!=none]

For example, to download the worst quality video-only format you can use
-f worstvideo. It is however recomended to never actually use worst and
related options. When your format selector is worst, the format which is
worst in all respects is selected. Most of the time, what you actually
want is the video with the smallest filesize instead. So it is generally
better to use -f best -S +size,+br,+res,+fps instead of -f worst. See
sorting formats for more details.

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 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 merge the video and audio of multiple formats into a single file
using -f <format1>+<format2>+... (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. If --no-video-multistreams is used, all formats with a
video stream except the first one are ignored. Similarly, if
--no-audio-multistreams is used, all formats with an audio stream except
the first one are ignored. For example, -f bestvideo+best+bestaudio will
download and merge all 3 given formats. The resulting file will have 2
video streams and 2 audio streams. But
-f bestvideo+best+bestaudio --no-video-multistreams will download and
merge only bestvideo and bestaudio. best is ignored since another format
containing a video stream (bestvideo) has already been selected. The
order of the formats is therefore important.
-f best+bestaudio --no-audio-multistreams will download and merge both
formats while -f bestaudio+best --no-audio-multistreams will ignore best
and download only bestaudio.


Filtering Formats

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), ^= (starts 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, mms, f4m, ism,
    http_dash_segments, m3u8, or m3u8_native)
-   format_id: A short description of the format
-   language: Language code

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. Any other
field made available by the extractor can also be used for filtering.

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.

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]'.


Sorting Formats

You can change the criteria for being considered the best by using -S
(--format-sort). The general format for this is
--format-sort field1,field2.... The available fields are:

-   hasvid: Gives priority to formats that has a video stream
-   hasaud: Gives priority to formats that has a audio stream
-   ie_pref: The format preference as given by the extractor
-   lang: Language preference as given by the extractor
-   quality: The quality of the format. This is a metadata field
    available in some websites
-   source: Preference of the source as given by the extractor
-   proto: Protocol used for download (https/ftps > http/ftp >
    m3u8-native > m3u8 > http-dash-segments > other > mms/rtsp >
    unknown > f4f/f4m)
-   vcodec: Video Codec (vp9 > h265 > h264 > vp8 > h263 > theora >
    other > unknown)
-   acodec: Audio Codec (opus > vorbis > aac > mp4a > mp3 > ac3 > dts >
    other > unknown)
-   codec: Equivalent to vcodec,acodec
-   vext: Video Extension (mp4 > webm > flv > other > unknown). If
    --prefer-free-formats is used, webm is prefered.
-   aext: Audio Extension (m4a > aac > mp3 > ogg > opus > webm > other >
    unknown). If --prefer-free-formats is used, the order changes to
    opus > ogg > webm > m4a > mp3 > aac.
-   ext: Equivalent to vext,aext
-   filesize: Exact filesize, if know in advance. This will be
    unavailable for mu38 and DASH formats.
-   fs_approx: Approximate filesize calculated from the manifests
-   size: Exact filesize if available, otherwise approximate filesize
-   height: Height of video
-   width: Width of video
-   res: Video resolution, calculated as the smallest dimension.
-   fps: Framerate of video
-   tbr: Total average bitrate in KBit/s
-   vbr: Average video bitrate in KBit/s
-   abr: Average audio bitrate in KBit/s
-   br: Equivalent to using tbr,vbr,abr
-   asr: Audio sample rate in Hz

Note that any other NUMERICAL field made available by the extractor can
also be used. All fields, unless specified otherwise, are sorted in
decending order. To reverse this, prefix the field with a +. Eg: +res
prefers format with the smallest resolution. Additionally, you can
suffix a prefered value for the fields, seperated by a :. Eg: res:720
prefers larger videos, but no larger than 720p and the smallest video if
there are no videos less than 720p. For codec and ext, you can provide
two prefered values, the first for video and the second for audio. Eg:
+codec:avc:m4a (equivalent to +vcodec:avc,+acodec:m4a) sets the video
codec preference to h264 > h265 > vp9 > vp8 > h263 > theora and audio
codec preference to mp4a > aac > vorbis > opus > mp3 > ac3 > dts. You
can also make the sorting prefer the nearest values to the provided by
using ~ as the delimiter. Eg: filesize~1G prefers the format with
filesize closest to 1 GiB.

The fields hasvid, ie_pref, lang, quality are always given highest
priority in sorting, irrespective of the user-defined order. This
behaviour can be changed by using --force-format-sort. Apart from these,
the default order used is:
res,fps,codec,size,br,asr,proto,ext,hasaud,source,id. Note that the
extractors may override this default order, but they cannot override the
user-provided order.

If your format selector is worst, the last item is selected after
sorting. This means it will select the format that is worst in all
repects. Most of the time, what you actually want is the video with the
smallest filesize instead. So it is generally better to use
-f best -S +size,+br,+res,+fps.

TIP: You can use the -v -F to see how the formats have been sorted
(worst to best).


Format Selection examples

Note that on Windows you may need to use double quotes instead of
single.

    # Download and merge the best best video-only format and the best audio-only format,
    # or download the best combined format if video-only format is not available
    $ youtube-dlc -f 'bv+ba/b'

    # Download best format that contains video,
    # and if it doesn't already have an audio stream, merge it with best audio-only format
    $ youtube-dlc -f 'bv*+ba/b'

    # Same as above
    $ youtube-dlc

    # Download the best video-only format and the best audio-only format without merging them
    # For this case, an output template should be used since
    # by default, bestvideo and bestaudio will have the same file name.
    $ youtube-dlc -f 'bv,ba' -o '%(title)s.f%(format_id)s.%(ext)s'



    # The following examples show the old method (without -S) of format selection
    # and how to use -S to achieve a similar but better result

    # Download the worst video available (old method)
    $ youtube-dlc -f 'wv*+wa/w'

    # Download the best video available but with the smallest resolution
    $ youtube-dlc -S '+res'

    # Download the smallest video available
    $ youtube-dlc -S '+size,+br'



    # Download the best mp4 video available, or the best video if no mp4 available
    $ youtube-dlc -f 'bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4] / bv*+ba/b'

    # Download the best video with the best extension
    # (For video, mp4 > webm > flv. For audio, m4a > aac > mp3 ...)
    $ youtube-dlc -S 'ext'



    # Download the best video available but no better than 480p,

    $ youtube-dlc -S 'height:480'

    # Download the best video available with the largest resolution but no better than 480p,
    # or the best video with the smallest resolution if there is no video under 480p
    # Resolution is determined by using the smallest dimension.
    # So this works correctly for vertical videos as well
    $ youtube-dlc -S 'res:480'



    # Download the best video (that also has audio) but no bigger than 50 MB,
    # or the worst video (that also has audio) if there is no video under 50 MB
    $ youtube-dlc -f 'b[filesize<50M] / w'

    # Download largest video (that also has audio) but no bigger than 50 MB,
    # or the smallest video (that also has audio) if there is no video under 50 MB

    $ youtube-dlc -f 'b' -S 'filesize~50M'



    # Download best video available via direct link over HTTP/HTTPS protocol,
    # or the best video available via any protocol if there is no such video
    $ youtube-dlc -f '(bv*+ba/b)[protocol^=http][protocol!*=dash] / (bv*+ba/b)'

    # Download best video available via the best protocol
    # (https/ftps > http/ftp > m3u8_native > m3u8 > http_dash_segments ...)
    $ youtube-dlc -S 'proto'



    # Download the best video with h264 codec, or the best video if there is no such video
    $ youtube-dlc -f '(bv*+ba/b)[vcodec^=avc1] / (bv*+ba/b)'

    # Download the best video with best codec no better than h264,

    # Download the best video with worst codec no worse than h264,
    # or the best video with best codec if there is no such video
    $ youtube-dlc -S '+codec:h264'



    # More complex examples

    # Download the best video no better than 720p prefering framerate greater than 30,
    # or the worst video (still prefering framerate greater than 30) if there is no such video
    $ youtube-dlc -f '((bv*[fps>30]/bv*)[height<=720]/(wv*[fps>30]/wv*)) + ba / (b[fps>30]/b)[height<=720]/(w[fps>30]/w)'
