YouTube/ORF-Download

Bei Recherchen über den „Böhmischen Prater“ im Jahr 2019 zitierte ich das Lied „Zwischen Simmering und Favoriten“ von Maria von Schmedes und gab als Quelle eine YouTube-Version dieses Musikstücks an. So schaute damals die YouTube-Seite aus:

https://www.youtube.com/watch?v=QRFMJkWcrc8

Bei einer kürzlichen Überarbeitung dieser Dokumentation stellte ich fest, dass dieses Lied nicht mehr frei verfügbar ist, sondern nur mehr im Rahmen eines Bezahlabos hörbar ist.

Es gibt zwar mit einer Version Charlotte Ludwig einen Ersatz,

aber es ist eine Cover-Version – und Original ist eben Original.

Hätte ich mir doch damals das Lied heruntergeladen! Man sieht, dass ich das nicht oft mache – YouTube-Dateien downloaden – daher suchte ich nach einer verlässlichen Lösung.

youtube-dl https://youtube-dl.org/

Einen Praxis-Tipp bekam ich in Twitter, dort wurde das Kommandozeilen-Programm youtube-dl empfohlen. Es gibt eine saubere Homepage mit einem Download-Button. Man speichert die .exe.Datei in einem Ordner des Pfads und ruft das Programm im Arbeitsverzeichnis – bei mir ist es der Desktop – in einem Terminal-Fenster auf. Der folgende Ablauf zeigt den Download von zwei YouTube-Videos:

Diese neue Version des YouTube-Downloader funktioniert also auch für die neueren Uploads. Die mächtige Liste der Optionen ist weiter hinten abgedruckt.

Download von Sendungen aus der ORF-TvThek

Ein interessanter Nebeneffekt ist, dass das Programm keineswegs nur Videos aus YouTube, sondern auch etwa solche aus der ORF-TvThek downloaden kann – und wahrscheinlich viele andere auch. Einfach die verpasste Sendung auswählten, den Url kopieren und mit

    --update-to [CHANNEL]@[TAG]     Upgrade/downgrade to a specific version.
                                    CHANNEL and TAG defaults to "stable" and
                                    "latest" respectively if omitted; See

    -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)

    --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

    --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
                                    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@127.0.0.1:1080/.
                                    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-restriction:
    --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 (default)
    --no-geo-bypass                 Do not bypass geographic restriction via
                                    faking X-Forwarded-For HTTP header
    --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 &
                                    description~='(?i)\bcats \& dogs\b'" matches

                                    the video/audio codec, remuxing will fail.
                                    You can specify multiple rules; e.g.
                                    "aac>m4a/mov>mp4/mkv" will remux aac to m4a,
                                    mov to mp4 and anything else to mkv
    --recode-video FORMAT           Re-encode the video into another format if

                                    FFmpeg and FFprobe. You can also specify
                                    "PP+EXE:ARGS" to give the arguments to the
                                    specified executable only when being used by
                                    the specified postprocessor. Additionally,
                                    for ffmpeg/ffprobe, "_i"/"_o" can be
                                    appended to the prefix optionally followed

                                    "Merger+ffmpeg_i1:-v quiet". You can use
                                    this option multiple times to give different
                                    arguments to different postprocessors.

                                    show). All the video files must have same
                                    codecs and number of streams to be
                                    concatable. The "pl_video:" prefix can be
                                    used with "--paths" and "--output" to set
                                    the output filename for the concatenated

                                    Supported values of "WHEN" are the same as
                                    that of --use-postprocessor (default:
                                    after_move). Same syntax as the output
                                    template can be used to pass any field as
                                    arguments to the command. After download, an
                                    additional field "filepath" that contains
                                    the final path of the downloaded file is
                                    also available, and if no fields are passed,
                                    %(filepath,_filename|)q is appended to the
                                    end of the command. This option can be used
                                    multiple times

    --split-chapters                Split video into multiple files based on
                                    internal chapters. The "chapter:" prefix can
                                    be used with "--paths" and "--output" to set
                                    the output filename for the split files. See
                                    "OUTPUT TEMPLATE" for details
    --no-split-chapters             Do not split video based on chapters

                                    be used multiple times
    --no-remove-chapters            Do not remove any chapters from the file
                                    (default)

                                    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]

                                    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),
                                    "video" (after --format; before
                                    --print/--output), "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
