yt-dlp下载方式
简介
yt-dlp是开源项目youtube-dl的一个分支，相当于是plus版，它的下载功能更加强大。
其实youtube-dl的下载功能曾因触动了某些公司的利益而遭到投诉，声称该软件违反了千年数字法案，侵犯了他们的版权，因此GitHub曾经将该项目下架，但是GitHub的CEO得知了这件事后表示反对并表态支持开发者，马上要求重新评估该项目并在联系youtube-dl的原作者后恢复了项目仓库。
受此事件影响，GitHub官方决定建立100万美元的“开发者防御基金”，以保护开发者免于受到“无理的版权投诉”。
下载yt-dlp
yt-dlp项目地址：https://github.com/yt-dlp/yt-dlp
进入后点击右侧的Releases，然后下载对应平台的软件，我下载Linux版，
安装ffmpeg
yt-dlp有许多功能需要依赖于ffmpeg，安装方法可以看我的这篇文章：https://www.hash070.top/archives/ffmpeg-install-win.html
ffmpeg使用方法
找到你想要下载的Youtube视频，这里我以这个视频为例，先复制视频上方的链接
下载方法：
yt-dlp_ -F https://www.youtube.com/watch?v=SzwXWwXCscM
执行完该命令后会看到如下表格
注意看VCODEC和ACODEC两列，如果某行的值为audio only或video only，则表示该行所代表的流是仅音频或仅视频的。
挑选好你需要下载的音频流或视频流的ID，然后就可以下载了
下载命令的格式如下：
yt-dlp_x86.exe -f [ID] [视频地址]
如果想下载音频格式为m4a纯音频文件，则应该输入命令
yt-dlp -f 140 https://www.youtube.com/watch?v=SzwXWwXCscM
如果想下载格式为mp4的纯视频文件，则应该输入命令
yt-dlp -f 137 https://www.youtube.com/watch?v=SzwXWwXCscM
如果想同时下载音频和视频并在下载后将它们合并，则应输入命令
可以在命令中通过 音频id+视频id 的方式时实现
yt-dlp -f 140+137 https://www.youtube.com/watch?v=SzwXWwXCscM
PIP安装方式
#安装依赖

1、简单用法（一个参数URL） yt-dlp.exe 视频URL
yt-dlp https://www.youtube.com/watch?v=u3LJVu8jNfM
选择格式：
yt-dlp --merge-output-format mp4 https://www.youtube.com/watch?v=u3LJVu8jNfM
[options]可用选项
General Options（全局选项）:
-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)
--update-to [CHANNEL]@[TAG] Upgrade/downgrade to a specific version.
CHANNEL and TAG defaults to "stable" and
"latest" respectively if omitted; See
"UPDATE" for details. Supported channels:
stable, nightly
-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
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（网络选项）:
--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（网络代理）
--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
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-match-filter Do not use any --match-filter (default)
--break-match-filters FILTER Same as "--match-filters" but stops the
download process when a video is rejected
--no-break-match-filters Do not use any --break-match-filters (default)

--break-match-filter, and autonumber to
reset per input URL
--no-break-per-input --break-on-existing and similar options
terminates the entire download queue
--skip-playlist-after-errors N Number of allowed failures until the rest of
the playlist is skipped
Download Options:
-N, --concurrent-fragments N Number of fragments of a dash/hlsnative
video that should be downloaded concurrently
(default is 1)

e.g. 50K or 4.2M
--throttled-rate RATE Minimum download rate in bytes per second
below which throttling is assumed and the
video data is re-extracted, e.g. 100K
-R, --retries RETRIES Number of retries (default is 10), or
"infinite"
--file-access-retries RETRIES Number of times to retry on file access
error (default is 3), or "infinite"
--fragment-retries RETRIES Number of retries for a fragment (default is
10), or "infinite" (DASH, hlsnative and ISM)
