yt-dlpの使い方備忘録 1
yt-dlpはPython 3.7以上の環境で動作します。つまりyoutube-dlとは異なり古いPythonでは動作しません。youtube-dlと同じくffmpegもインストールしておきます。
python3 -m pip install -U yt-dlp (インストール/更新共に)


$ yt-dlp 動画URL
$ yt-dlp 動画ID
$ yt-dlp プレイリストID   (プレイリストIDの前に -i を追加するとエラーを無視するのでオススメ)

YouTubeだと のようなのが動画URL、そのv=の後の00000000000が動画ID。 のlist=の後のAAAAAAAAAAAAAがプレイリストID。

    -U, --update                                            Check if updates are available. You installed yt-dlp with pip or using the
                                                            wheel from PyPi; Use that to update
    --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)

    --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
    --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-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

    --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
    --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
                                                            seconds (or range) to wait between retries
    --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

  Network Options:
    --proxy URL                                             Use the specified HTTP/HTTPS/SOCKS proxy. To enable SOCKS proxy, specify a
                                                            proper scheme, e.g. socks5://user:pass@ Pass in an empty
                                                            string (--proxy "") for direct connection
    --socket-timeout SECONDS                                Time to wait before giving up, in seconds
    --source-address IP                                     Client-side IP address to bind to
    -4, --force-ipv4                                        Make all connections via IPv4
    -6, --force-ipv6                                        Make all connections via IPv6
    --enable-file-urls                                      Enable file:// URLs. This is disabled by default for security reasons.

    --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 downloading
    --geo-bypass                                            Bypass geographic restriction via faking X-Forwarded-For HTTP header
    --no-geo-bypass                                         Do not bypass geographic restriction via faking X-Forwarded-For HTTP
    --geo-bypass-country CODE                               Force bypass geographic restriction with explicitly provided two-letter
                                                            ISO 3166-2 country code
    --geo-bypass-ip-block IP_BLOCK                          Force bypass geographic restriction with explicitly provided IP block in
                                                            CIDR notation

  Video Selection:
    -I, --playlist-items ITEM_SPEC                          Comma separated playlist_index of the items 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 items at index 1,2,3,7,11,13,15
    --min-filesize SIZE                                     Abort download if filesize is smaller than SIZE, e.g. 50k or 44.6M
    --max-filesize SIZE                                     Abort download if filesize is larger than SIZE, 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" downloads only videos uploaded on the same day two weeks ago
    --datebefore DATE                                       Download only videos uploaded on or before this date. The date formats
                                                            accepted is the same as --date
    --dateafter DATE                                        Download only videos uploaded on or after this date. The date formats
                                                            accepted is the same as --date
    --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 &

                                                            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 &

  Download Options:
    -N, --concurrent-fragments N                            Number of fragments of a dash/hlsnative video that should be downloaded
                                                            concurrently (default is 1)

フォーマットリストを見るのが面倒な場合、 -f bestvideo+bestaudio (最高動画+最高音声)や -f bv.2;ba.2 (2番めに良い動画+2番めに良い音声)のような指定もできますが、最高動画+最高音声ならオプションなしと実質同じですし、2番めに良いというのは使い方としてはちょっと指定する動機がわかりません。
-f "best[height=720]" (HD解像度の最高動画)のような指定は動機として理解できます。
