+### Differences in default behavior
+
+Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc.
+
+* The options `--id`, `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
+* `avconv` is not supported as as an alternative to `ffmpeg`
+* The default [output template](#output-template) is `%(title)s [%(id)s].%(ext)s`. There is no real reason for this change. This was changed before yt-dlp was ever made public and now there are no plans to change it back to `%(title)s.%(id)s.%(ext)s`. Instead, you may use `--compat-options filename`
+* The default [format sorting](sorting-formats) is different from youtube-dl and prefers higher resolution and better codecs rather than higher bitrates. You can use the `--format-sort` option to change this to any order you prefer, or use `--compat-options format-sort` to use youtube-dl's sorting order
+* The default format selector is `bv*+ba/b`. This means that if a combined video + audio format that is better than the best video-only format is found, the former will be prefered. Use `-f bv+ba/b` or `--compat-options format-spec` to revert this
+* Unlike youtube-dlc, yt-dlp does not allow merging multiple audio/video streams into one file by default (since this conflicts with the use of `-f bv*+ba`). If needed, this feature must be enabled using `--audio-multistreams` and `--video-multistreams`. You can also use `--compat-options multistreams` to enable both
+* `--ignore-errors` is enabled by default. Use `--abort-on-error` or `--compat-options abort-on-error` to abort on errors instead
+* When writing metadata files such as thumbnails, description or infojson, the same information (if available) is also written for playlists. Use `--no-write-playlist-metafiles` or `--compat-options no-playlist-metafiles` to not write these files
+* `--add-metadata` attaches the `infojson` to `mkv` files in addition to writing the metadata when used with `--write-infojson`. Use `--compat-options no-attach-info-json` to revert this
+* `playlist_index` behaves differently when used with options like `--playlist-reverse` and `--playlist-items`. See [#302](https://github.com/yt-dlp/yt-dlp/issues/302) for details. You can use `--compat-options playlist-index` if you want to keep the earlier behavior
+* The output of `-F` is listed in a new format. Use `--compat-options list-formats` to revert this
+* Youtube live chat (if available) is considered as a subtitle. Use `--sub-langs all,-live_chat` to download all subtitles except live chat. You can also use `--compat-options no-live-chat` to prevent live chat from downloading
+* Youtube channel URLs are automatically redirected to `/video`. Append a `/featured` to the URL to download only the videos in the home page. If the channel does not have a videos tab, we try to download the equivalent `UU` playlist instead. Also, `/live` URLs raise an error if there are no live videos instead of silently downloading the entire channel. You may use `--compat-options no-youtube-channel-redirect` to revert all these redirections
+* Unavailable videos are also listed for youtube playlists. Use `--compat-options no-youtube-unavailable-videos` to remove this
+* If `ffmpeg` is used as the downloader, the downloading and merging of formats happen in a single step when possible. Use `--compat-options no-direct-merge` to revert this
+* Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
+
+For ease of use, a few more compat options are available:
+* `--compat-options all`: Use all compat options
+* `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams`
+* `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect`
+
# INSTALLATION

You can install yt-dlp using one of the following methods:
* Download the binary from the [latest release](https://github.com/yt-dlp/yt-dlp/releases/latest) (recommended method)
-* Use [PyPI package](https://pypi.org/project/yt-dlp): `python -m pip install --upgrade yt-dlp`
-* Use pip+git: `python -m pip install --upgrade git+https://github.com/yt-dlp/yt-dlp.git@release`
-* Install master branch: `python -m pip install --upgrade git+https://github.com/yt-dlp/yt-dlp`
+* Use [PyPI package](https://pypi.org/project/yt-dlp): `python3 -m pip install --upgrade yt-dlp`
+* Use pip+git: `python3 -m pip install --upgrade git+https://github.com/yt-dlp/yt-dlp.git@release`
+* Install master branch: `python3 -m pip install --upgrade git+https://github.com/yt-dlp/yt-dlp`
+
+Note that on some systems, you may need to use `py` or `python` instead of `python3`
UNIX users (Linux, macOS, BSD) can also install the [latest release](https://github.com/yt-dlp/yt-dlp/releases/latest) one of the following ways:
sudo chmod a+rx /usr/local/bin/yt-dlp
```
-### DEPENDENCIES
-Python versions 2.6, 2.7, or 3.2+ are currently supported. However, 3.2+ is strongly recommended and python2 support will be deprecated in the future.
-
-Although there are no required dependencies, `ffmpeg` and `ffprobe` are highly recommended. Other optional dependencies are `sponskrub`, `AtomicParsley`, `mutagen`, `pycryptodome` and any of the supported external downloaders. Note that the windows releases are already built with the python interpreter, mutagen and pycryptodome included.

```
It may however also contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to [python string formatting operations](https://docs.python.org/2/library/stdtypes.html#string-formatting). For example, `%(NAME)s` or `%(NAME)05d`. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations.
The field names themselves (the part inside the parenthesis) can also have some special formatting:
-1. **Date/time Formatting**: Date/time fields can be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it separated from the field name using a `>`. Eg: `%(duration>%H-%M-%S)s` or `%(upload_date>%Y-%m-%d)s`
-2. **Offset numbers**: Numeric fields can have an initial offset specified by using a `+` separator. Eg: `%(playlist_index+10)03d`. This can also be used in conjunction with the date-time formatting. Eg: `%(epoch+-3600>%H-%M-%S)s`
-3. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a `.` (dot) separator. Eg: `%(tags.0)s` or `%(subtitles.en.-1.ext)`. Note that the fields that become available using this method are not listed below. Use `-j` to see such fields
+1. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a `.` (dot) separator. You can also do python slicing using `:`. Eg: `%(tags.0)s`, `%(subtitles.en.-1.ext)`, `%(id.3:7:-1)s`. Note that the fields that become available using this method are not listed below. Use `-j` to see such fields
+1. **Addition**: Addition and subtraction of numeric fields can be done using `+` and `-` respectively. Eg: `%(playlist_index+10)03d`, `%(n_entries+1-playlist_index)d`
+1. **Date/time Formatting**: Date/time fields can be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it separated from the field name using a `>`. Eg: `%(duration>%H-%M-%S)s`, `%(upload_date>%Y-%m-%d)s`, `%(epoch-3600>%H-%M-%S)s`
+1. **Default**: A default value can be specified for when the field is empty using a `|` seperator. This overrides `--output-na-template`. Eg: `%(uploader|Unknown)s`
To summarize, the general syntax for a field is:
```
-%(name[.keys][+offset][>strf])[flags][width][.precision][length]type
+%(name[.keys][addition][>strf][|default])[flags][width][.precision][length]type
```
-Additionally, you can set different output templates for the various metadata files separately from the general output template by specifying the type of file followed by the template separated by a colon `:`. The different file types supported are `subtitle`, `thumbnail`, `description`, `annotation`, `infojson`, `pl_description`, `pl_infojson`, `chapter`. For example, `-o '%(title)s.%(ext)s' -o 'thumbnail:%(title)s\%(title)s.%(ext)s'` will put the thumbnails in a folder with the same name as the video.

Available for the video that belongs to some logical chapter or section:
- `section_start` (numeric): Start time of the chapter in seconds
- `section_end` (numeric): End time of the chapter in seconds
+Available only when used in `--print`:
+
+ - `urls` (string): The URLs of all requested formats, one in each line
+ - `filename` (string): Name of the video file. Note that the actual filename may be different due to post-processing. Use `--exec echo` to get the name after all postprocessing is complete
+
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 `yt-dlp test video` and id `BaW_jenozKcj`, this will result in a `yt-dlp test video-BaW_jenozKcj.mp4` file created in the current directory.
- `lang`: Language preference as given by the extractor
- `quality`: The quality of the format as given by the extractor
- `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`)

Note that any field created by this can be used in the [output template](#output-template) and will also affect the media file's metadata added when using `--add-metadata`.
-You can also use this to change only the metadata that is embedded in the media file. To do this, set the value of the corresponding field with a `meta_` prefix. For example, any value you set to `meta_description` field will be added to the `description` field in the file. You can use this to set a different "description" and "synopsis", for example.
+This option also has a few special uses:
+* You can use this to change the metadata that is embedded in the media file. To do this, set the value of the corresponding field with a `meta_` prefix. For example, any value you set to `meta_description` field will be added to the `description` field in the file. You can use this to set a different "description" and "synopsis", for example
+* You can download an additional URL based on the metadata of the currently downloaded video. To do this, set the field `additional_urls` to the URL that you want to download. Eg: `--parse-metadata "description:(?P<additional_urls>https?://www\.vimeo\.com/\d+)` will download the first vimeo video found in the description
## Modifying metadata examples
#### Not recommended
While these options still work, their use is not recommended since there are other alternatives to achieve the same
+ --get-description --print description
+ --get-duration --print duration_string
+ --get-filename --print filename
+ --get-format --print format
+ --get-id --print id
+ --get-thumbnail --print thumbnail
+ -e, --get-title --print title
+ -g, --get-url --print urls
--all-formats -f all
--all-subs --sub-langs all --write-subs
--autonumber-size NUMBER Use string formatting. Eg: %(autonumber)03d
--metadata-from-title FORMAT --parse-metadata "%(title)s:FORMAT"
--hls-prefer-native --downloader "m3u8:native"
--hls-prefer-ffmpeg --downloader "m3u8:ffmpeg"
+ --list-formats-old --compat-options list-formats (Alias: --no-list-formats-as-table)
+ --list-formats-as-table --compat-options -list-formats [Default] (Alias: --no-list-formats-old)
--sponskrub-args ARGS --ppa "sponskrub:ARGS"
--test Used by developers for testing extractors. Not intended for the end user
+ --youtube-print-sig-code Used for testing youtube signatures
#### Old aliases
--no-call-home Default
--include-ads No longer supported
--no-include-ads Default
- --youtube-print-sig-code No longer supported
+
+#### Removed
+These options were deprecated since 2014 and have now been entirely removed
+
--id -o "%(id)s.%(ext)s"
-A, --auto-number -o "%(autonumber)s-%(id)s.%(ext)s"
-t, --title -o "%(title)s-%(id)s.%(ext)s"
-l, --literal -o accepts literal names
-#### Removed
-Currently, there are no options that have been completely removed. But there are plans to remove the old output options `-A`,`-t`, `-l`, `--id` (which have been deprecated since 2014) in the near future. If you are still using these, please move to using `--output` instead
