一般オプション:

-h, --help                      Print this help text and exit
--version                       Print program version and exit
-U, --update                    Update this program to the latest version
--no-update                     Do not check for updates (default)
-i, --ignore-errors             Ignore download and postprocessing errors.
                                The download will be considered successful
                                even if the postprocessing fails
--no-abort-on-error             Continue with next video on download errors;
                                e.g. to skip unavailable videos in a
                                playlist (default)
--abort-on-error                Abort downloading of further videos if an
                                error occurs (Alias: --no-ignore-errors)
--dump-user-agent               Display the current user-agent and exit
--list-extractors               List all supported extractors and exit
--extractor-descriptions        Output descriptions of all supported
                                extractors and exit
--use-extractors NAMES          Extractor names to use separated by commas.
                                You can also use regexes, "all", "default"
                                and "end" (end URL matching); e.g. --ies
                                "holodex.*,end,youtube". Prefix the name
                                with a "-" to exclude it, e.g. --ies
                                default,-generic. Use --list-extractors for
                                a list of extractor names. (Alias: --ies)
--default-search PREFIX         Use this prefix for unqualified URLs. E.g.
                                "gvsearch2:python" downloads two videos from
                                google videos for the search term "python".
                                Use the value "auto" to let yt-dlp 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                 Don't load any more configuration files
                                except those given by --config-locations.
                                For backward compatibility, if this option
                                is found inside the system configuration
                                file, the user configuration is not loaded.
                                (Alias: --no-config)
--no-config-locations           Do not load any custom configuration files
                                (default). When given inside a configuration
                                file, ignore all previous --config-locations
                                defined in the current file
--config-locations PATH         Location of the main configuration file;
                                either the path to the config or its
                                containing directory ("-" for stdin). Can be
                                used multiple times and inside other
                                configuration files
--flat-playlist                 Do not extract the videos of a playlist,
                                only list them
--no-flat-playlist              Extract the videos of a playlist
--live-from-start               Download livestreams from the start.
                                Currently only supported for YouTube
                                (Experimental)
--no-live-from-start            Download livestreams from the current time
                                (default)
--wait-for-video MIN[-MAX]      Wait for scheduled streams to become
                                available. Pass the minimum number of

--no-wait-for-video             Do not wait for scheduled streams (default)
--mark-watched                  Mark videos watched (even with --simulate)
--no-mark-watched               Do not mark videos watched (default)
--no-colors                     Do not emit color codes in output (Alias:
                                --no-colours)
--compat-options OPTS           Options that can help keep compatibility
                                with youtube-dl or youtube-dlc
                                configurations by reverting some of the
                                changes made in yt-dlp. See "Differences in
                                default behavior" for details
--alias ALIASES OPTIONS         Create aliases for an option string. Unless
                                an alias starts with a dash "-", it is
                                prefixed with "--". Arguments are parsed
                                according to the Python string formatting
                                mini-language. E.g. --alias get-audio,-X
                                "-S=aext:{0},abr -x --audio-format {0}"
                                creates options "--get-audio" and "-X" that
                                takes an argument (ARG0) and expands to
                                "-S=aext:ARG0,abr -x --audio-format ARG0".
                                All defined aliases are listed in the --help
                                output. Alias options can trigger more
                                aliases; so be careful to avoid defining
                                recursive options. As a safety measure, each
                                alias may be triggered a maximum of 100
                                times. This option can be used multiple times

--geo-verification-proxy URL    Use this proxy to verify the IP address for
                                some geo-restricted sites. The default proxy
                                specified by --proxy (or none, if the option
                                is not present) is used for the actual

-I, --playlist-items ITEM_SPEC  Comma separated playlist_index of the videos
                                to download. You can specify a range using
                                "[START]:[STOP][:STEP]". For backward
                                compatibility, START-STOP is also supported.
                                Use negative indices to count from the right
                                and negative STEP to download in reverse
                                order. E.g. "-I 1:3,7,-5::2" used on a
                                playlist of size 15 will download the videos
                                at index 1,2,3,7,11,13,15
--min-filesize SIZE             Do not download any videos smaller than

                                e.g. 50k or 44.6M
--date DATE                     Download only videos uploaded on this date.
                                The date can be "YYYYMMDD" or in the format 
                                [now|today|yesterday][-N[day|week|month|year]].
                                E.g. --date today-2weeks
--datebefore DATE               Download only videos uploaded on or before
                                this date. The date formats accepted is the

--match-filters FILTER          Generic video filter. Any "OUTPUT TEMPLATE"
                                field can be compared with a number or a
                                string using the operators defined in
                                "Filtering Formats". You can also simply
                                specify a field to match if the field is
                                present, use "!field" to check if the field
                                is not present, and "&" to check multiple
                                conditions. Use a "\" to escape "&" or
                                quotes if needed. If used multiple times,
                                the filter matches if atleast one of the
                                conditions are met. E.g. --match-filter
                                !is_live --match-filter "like_count>?100 &
                                description~='(?i)\bcats \& dogs\b'" matches
                                only videos that are not live OR those that
                                have a like count more than 100 (or the like
                                field is not available) and also has a
                                description that contains the phrase "cats &
                                dogs" (caseless). Use "--match-filter -" to
                                interactively ask whether to download each
                                video

--no-split-chapters             Do not split video based on chapters (default)
--remove-chapters REGEX         Remove chapters whose title matches the
                                given regular expression. The syntax is the
                                same as --download-sections. This option can
                                be used multiple times
--no-remove-chapters            Do not remove any chapters from the file
                                (default)
--force-keyframes-at-cuts       Force keyframes at cuts when
                                downloading/splitting/removing sections.
                                This is slow due to needing a re-encode, but
                                the resulting video may have fewer artifacts
                                around the cuts
--no-force-keyframes-at-cuts    Do not force keyframes around the chapters
                                when cutting/splitting (default)
--use-postprocessor NAME[:ARGS]
                                The (case sensitive) name of plugin
                                postprocessors to be enabled, and
                                (optionally) arguments to be passed to it,
                                separated by a colon ":". ARGS are a
                                semicolon ";" delimited list of NAME=VALUE.
                                The "when" argument determines when the
                                postprocessor is invoked. It can be one of
                                "pre_process" (after video extraction),
                                "after_filter" (after video passes filter),
                                "before_dl" (before each video download),
                                "post_process" (after each video download;
                                default), "after_move" (after moving video
                                file to it's final locations), "after_video"
                                (after downloading and processing all
                                formats of a video), or "playlist" (at end
                                of playlist). This option can be used
                                multiple times to add different postprocessors

                                fields are start_time, end_time, category,
                                categories, name, category_names. Defaults
                                to "[SponsorBlock]: %(category_names)l"
--no-sponsorblock               Disable both --sponsorblock-mark and
                                --sponsorblock-remove
--sponsorblock-api URL          SponsorBlock API location, defaults to
                                https://sponsor.ajay.app

抽出器オプション:

--extractor-retries RETRIES     Number of retries for known extractor errors
                                (default is 3), or "infinite"
--allow-dynamic-mpd             Process dynamic DASH manifests (default)

                                discontinuities such as ad breaks
--no-hls-split-discontinuity    Do not split HLS playlists to different
                                formats at discontinuities such as ad breaks
                                (default)
--extractor-args IE_KEY:ARGS    Pass ARGS arguments to the IE_KEY extractor.
                                See "EXTRACTOR ARGUMENTS" for details. You
                                can use this option multiple times to give
                                arguments for different extractors

構成

yt-dlp を構成するには、サポートされているコマンドラインオプションを構成ファイルに配置します。構成は、次の場所からロードされます。

1. メイン構成: によって指定されたファイル

   --config-location

2. ポータブル構成:バンドルされたバイナリと同じディレクトリ内。ソースコード()から実行している場合は、代わりにルートディレクトリが使用されます。

   yt-dlp.conf

   <root dir>/yt_dlp/__main__.py

3. ホーム設定: によって指定されたホームパス内、またはそのようなパスが指定されていない場合は現在のディレクトリ内

   yt-dlp.conf

   -P

4. ユーザー構成:

   • $XDG_CONFIG_HOME/yt-dlp/config

     (Linux/macOSで推奨)

   • $XDG_CONFIG_HOME/yt-dlp.conf

   • $APPDATA/yt-dlp/config

     (ウィンドウズで推奨)

   • $APPDATA/yt-dlp/config.txt

   • ~/yt-dlp.conf

   • ~/yt-dlp.conf.txt

   $XDG_CONFIG_HOME

   デフォルトは未定義の場合です。ウィンドウでは、通常、 を指し、存在する場合は (通常は)、または を指します。

   ~/.config

   $APPDATA

   C:\Users\<user name>\AppData\Roaming

   ~

   $HOME

   $USERPROFILE

   C:\Users\<user name>

   ${HOMEDRIVE}${HOMEPATH}

5. システム構成:

   /etc/yt-dlp.conf

たとえば、次の設定ファイルを使用すると、yt-dlpは常にオーディオを抽出し、mtimeをコピーし、プロキシを使用してホームディレクトリのディレクトリにすべてのビデオを保存します。

YouTube

# 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

設定ファイルのオプションは、通常のコマンドライン呼び出しで使用されるスイッチと同じオプションであることに注意してください。したがって、 または の後に空白があってはなりません。 または、または.また、必要に応じて、UNIXシェルの場合と同様に引用符で囲む必要があります。

-o

--proxy

-- proxy

特定の yt-dlp 実行のすべての構成ファイルを無効にする場合に使用できます。が設定されている場合、それ以上の設定はロードされません。たとえば、ポータブル構成ファイルにこのオプションを指定すると、ホーム、ユーザー、およびシステム構成の読み込みが防止されます。さらに、(下位互換性のために) システム構成ファイル内で見つかった場合、ユーザー構成はロードされません。

--ignore-config

--ignore-config

--ignore-config

設定ファイルのエンコーディング

設定ファイルは、UTF BOM が存在する場合はそれに従ってデコードされ、それ以外の場合はシステムロケールからのエンコーディングでデコードされます。

ファイルのデコード方法を異なる方法で行う場合は、ファイルの先頭に追加します (例: )。その前には、スペースやBOMでさえも文字があってはなりません。

# coding: ENCODING

# coding: shift-jis

ファイルによる認証

.netrc

また、認証をサポートするエクストラクター用に自動資格情報ストレージを構成することもできます (login とパスワードを指定することにより、 と を指定することによって)、すべての yt-dlp 実行時に資格情報をコマンド行引数として渡さず、シェル・コマンド・ヒストリーでプレーン・テキスト・パスワードを追跡できないようにすることもできます。これは、エクストラクターごとに .netrc ファイルを使用して実現できます。そのためには、ファイルを作成し、あなただけが読み取り/書き込みする権限を制限する必要があります。

--username
