* [MORE](#more)
* **[Format Sorting](#sorting-formats)**: The default format sorting options have been changed so that higher resolution and better codecs will be now preferred instead of simply using larger bitrate. Furthermore, you can now specify the sort order using `-S`. This allows for much easier format selection that what is possible by simply using `--format` ([examples](#format-selection-examples))

# INSTALLATION
You can install yt-dlp using one of the following methods:
-* Use [PyPI package](https://pypi.org/project/yt-dlp/): `python -m pip install --upgrade yt-dlp`
-* Download the binary from the [latest release](https://github.com/pukkandan/yt-dlp/releases/latest)
+* Download the binary from the [latest release](https://github.com/pukkandan/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/pukkandan/yt-dlp.git@release`
* Install master branch: `python -m pip install --upgrade git+https://github.com/pukkandan/yt-dlp`
### UPDATE
-`-U` does not work. Simply repeat the install process to update.
+Starting from version `2021.02.09`, you can use `youtube-dlc -U` to update if you are using the provided release.
+If you are using `pip`, simply re-run the same command that was used to install the program.
### COMPILE
**For Windows**:
-To build the Windows executable yourself (without version info!)
+To build the Windows executable, you must have pyinstaller (and optionally mutagen and pycryptodome)
- python -m pip install --upgrade pyinstaller
- pyinstaller.exe youtube_dlc\__main__.py --onefile --name youtube-dlc
-
-Or simply execute the `make_win.bat` if pyinstaller is installed.
-There will be a `youtube-dlc.exe` in `/dist`
+ python -m pip install --upgrade pyinstaller mutagen pycryptodome
-New way to build Windows is to use `python pyinst.py` (please use python3 64Bit)
-For 32Bit Version use a 32Bit Version of python (3 preferred here as well) and run `python pyinst32.py`
+Once you have all the necessary dependancies installed, just run `py pyinst.py`. The executable will be built for the same architecture (32/64 bit) as the python used to build it. It is strongly reccomended to use python3 although python2.6+ is supported.
+
+You can also build the executable without any version info or metadata by using:
+
+ pyinstaller.exe youtube_dlc\__main__.py --onefile --name youtube-dlc
**For Unix**:
You will need the required build tools
make
+**Note**: In either platform, `devscripts\update-version.py` can be used to automatically update the version number

You can configure youtube-dlc by placing any supported command line option to a configuration file. The configuration is loaded from the following locations:
-1. The file given by `--config-location`
+1. **Main Configuration**: The file given by `--config-location`
1. **Portable Configuration**: `yt-dlp.conf` or `youtube-dlc.conf` in the same directory as the bundled binary. If you are running from source-code (`<root dir>/youtube_dlc/__main__.py`), the root directory is used instead.
+1. **Home Configuration**: `yt-dlp.conf` or `youtube-dlc.conf` in the home path given by `-P "home:<path>"`, or in the current directory if no such path is given
1. **User Configuration**:
* `%XDG_CONFIG_HOME%/yt-dlp/config` (recommended on Linux/macOS)
* `%XDG_CONFIG_HOME%/yt-dlp.conf`
# OUTPUT TEMPLATE
-The `-o` option allows users to indicate a template for the output file names.
+The `-o` option is used to indicate a template for the output file names while `-P` option is used to specify the path each type of file should be saved to.
**tl;dr:** [navigate me to examples](#output-template-examples).
-The basic usage is not to set any template arguments when downloading a single file, like in `youtube-dlc -o funny_video.flv "https://some/video"`. However, it may 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. Allowed names along with sequence type are:

To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations. Date/time fields can also be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it inside the parantheses seperated from the field name using a `>`. For example, `%(duration>%H-%M-%S)s`.
+
+Additionally, you can set different output templates for the various metadata files seperately from the general output template by specifying the type of file followed by the template seperated by a colon ":". The different filetypes supported are `subtitle|thumbnail|description|annotation|infojson|pl_description|pl_infojson`. 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.
+
+The available fields are:
- `id` (string): Video identifier
- `title` (string): Video title
- `is_live` (boolean): Whether this video is a live stream or a fixed-length video
- `start_time` (numeric): Time in seconds where the reproduction should start, as specified in the URL
- `end_time` (numeric): Time in seconds where the reproduction should end, as specified in the URL
- - `format` (string): A human-readable description of the format
+ - `format` (string): A human-readable description of the format
- `format_id` (string): Format code specified by `--format`
- `format_note` (string): Additional info about the format
- `width` (numeric): Width of the video
- `disc_number` (numeric): Number of the disc or other physical medium the track belongs to
- `release_year` (numeric): Year (YYYY) when the album was released
-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 `NA`.
+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 `youtube-dlc test video` and id `BaW_jenozKcj`, this will result in a `youtube-dlc test video-BaW_jenozKcj.mp4` file created in the current directory.

# FORMAT SELECTION
By default, youtube-dlc tries to download the best available quality if you **don't** pass any options.
-This is generally equivalent to using `-f bestvideo*+bestaudio/best`. However, if multiple audiostreams is enabled (`--audio-multistreams`), the default format changes to `-f bestvideo+bestaudio/best`. Similarly, if ffmpeg and avconv are unavailable, or if you use youtube-dlc to stream to `stdout` (`-o -`), the default becomes `-f best/bestvideo+bestaudio`.
+This is generally equivalent to using `-f bestvideo*+bestaudio/best`.

Similarly, if ffmpeg is unavailable, or if you use youtube-dlc to stream to `stdout` (`-o -`), the default becomes `-f best/bestvideo+bestaudio`.
The general syntax for format selection is `--f FORMAT` (or `--format FORMAT`) where `FORMAT` is a *selector expression*, i.e. an expression that describes format or formats you would like to download.
If you want to download several formats of the same video use a comma as a separator, e.g. `-f 22,17,18` will download all these three formats, of course if they are available. Or a more sophisticated example combined with the precedence feature: `-f 136/137/mp4/bestvideo,140/m4a/bestaudio`.
-You can merge the video and audio of multiple formats into a single file using `-f <format1>+<format2>+...` (requires ffmpeg or avconv installed), for example `-f bestvideo+bestaudio` will download the best video-only format, the best audio-only format and mux them together with ffmpeg/avconv. If `--no-video-multistreams` is used, all formats with a video stream except the first one are ignored. Similarly, if `--no-audio-multistreams` is used, all formats with an audio stream except the first one are ignored. For example, `-f bestvideo+best+bestaudio` will download and merge all 3 given formats. The resulting file will have 2 video streams and 2 audio streams. But `-f bestvideo+best+bestaudio --no-video-multistreams` will download and merge only `bestvideo` and `bestaudio`. `best` is ignored since another format containing a video stream (`bestvideo`) has already been selected. The order of the formats is therefore important. `-f best+bestaudio --no-audio-multistreams` will download and merge both formats while `-f bestaudio+best --no-audio-multistreams` will ignore `best` and download only `bestaudio`.
+You can merge the video and audio of multiple formats into a single file using `-f <format1>+<format2>+...` (requires ffmpeg installed), for example `-f bestvideo+bestaudio` will download the best video-only format, the best audio-only format and mux them together with ffmpeg. If `--no-video-multistreams` is used, all formats with a video stream except the first one are ignored. Similarly, if `--no-audio-multistreams` is used, all formats with an audio stream except the first one are ignored. For example, `-f bestvideo+best+bestaudio` will download and merge all 3 given formats. The resulting file will have 2 video streams and 2 audio streams. But `-f bestvideo+best+bestaudio --no-video-multistreams` will download and merge only `bestvideo` and `bestaudio`. `best` is ignored since another format containing a video stream (`bestvideo`) has already been selected. The order of the formats is therefore important. `-f best+bestaudio --no-audio-multistreams` will download and merge both formats while `-f bestaudio+best --no-audio-multistreams` will ignore `best` and download only `bestaudio`.
## Filtering Formats
You can change the criteria for being considered the `best` by using `-S` (`--format-sort`). The general format for this is `--format-sort field1,field2...`. The available fields are:
- - `video`, `has_video`: Gives priority to formats that has a video stream
- - `audio`, `has_audio`: Gives priority to formats that has a audio stream
- - `extractor`, `preference`, `extractor_preference`: The format preference as given by the extractor
- - `lang`, `language_preference`: Language preference as given by the extractor
+ - `hasvid`: Gives priority to formats that has a video stream
+ - `hasaud`: Gives priority to formats that has a audio stream
+ - `ie_pref`: The format preference as given by the extractor
+ - `lang`: Language preference as given by the extractor
- `quality`: The quality of the format. This is a metadata field available in some websites
- - `source`, `source_preference`: Preference of the source as given by the extractor
- - `proto`, `protocol`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8-native` > `m3u8` > `http-dash-segments` > other > `mms`/`rtsp` > unknown > `f4f`/`f4m`)
- - `vcodec`, `video_codec`: Video Codec (`vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other > unknown)
- - `acodec`, `audio_codec`: Audio Codec (`opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac3` > `dts` > other > unknown)
+ - `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`)
+ - `vcodec`: Video Codec (`av01` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other > unknown)
+ - `acodec`: Audio Codec (`opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac3` > `dts` > other > unknown)
- `codec`: Equivalent to `vcodec,acodec`
- - `vext`, `video_ext`: Video Extension (`mp4` > `webm` > `flv` > other > unknown). If `--prefer-free-formats` is used, `webm` is prefered.
- - `aext`, `audio_ext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other > unknown). If `--prefer-free-formats` is used, the order changes to `opus` > `ogg` > `webm` > `m4a` > `mp3` > `aac`.
- - `ext`, `extension`: Equivalent to `vext,aext`
+ - `vext`: Video Extension (`mp4` > `webm` > `flv` > other > unknown). If `--prefer-free-formats` is used, `webm` is prefered.
+ - `aext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other > unknown). If `--prefer-free-formats` is used, the order changes to `opus` > `ogg` > `webm` > `m4a` > `mp3` > `aac`.
+ - `ext`: Equivalent to `vext,aext`
- `filesize`: Exact filesize, if know in advance. This will be unavailable for mu38 and DASH formats.
- - `filesize_approx`: Approximate filesize calculated from the manifests
- - `size`, `filesize_estimate`: Exact filesize if available, otherwise approximate filesize
+ - `fs_approx`: Approximate filesize calculated from the manifests
+ - `size`: Exact filesize if available, otherwise approximate filesize
- `height`: Height of video
- `width`: Width of video
- - `res`, `dimension`: Video resolution, calculated as the smallest dimension.
- - `fps`, `framerate`: Framerate of video
- - `tbr`, `total_bitrate`: Total average bitrate in KBit/s
- - `vbr`, `video_bitrate`: Average video bitrate in KBit/s
- - `abr`, `audio_bitrate`: Average audio bitrate in KBit/s
- - `br`, `bitrate`: Equivalent to using `tbr,vbr,abr`
- - `samplerate`, `asr`: Audio sample rate in Hz
+ - `res`: Video resolution, calculated as the smallest dimension.
+ - `fps`: Framerate of video
+ - `tbr`: Total average bitrate in KBit/s
+ - `vbr`: Average video bitrate in KBit/s
+ - `abr`: Average audio bitrate in KBit/s

+ - `asr`: Audio sample rate in Hz
Note that any other **numerical** field made available by the extractor can also be used. All fields, unless specified otherwise, are sorted in decending order. To reverse this, prefix the field with a `+`. Eg: `+res` prefers format with the smallest resolution. Additionally, you can suffix a prefered value for the fields, seperated by a `:`. Eg: `res:720` prefers larger videos, but no larger than 720p and the smallest video if there are no videos less than 720p. For `codec` and `ext`, you can provide two prefered values, the first for video and the second for audio. Eg: `+codec:avc:m4a` (equivalent to `+vcodec:avc,+acodec:m4a`) sets the video codec preference to `h264` > `h265` > `vp9` > `vp8` > `h263` > `theora` and audio codec preference to `mp4a` > `aac` > `vorbis` > `opus` > `mp3` > `ac3` > `dts`. You can also make the sorting prefer the nearest values to the provided by using `~` as the delimiter. Eg: `filesize~1G` prefers the format with filesize closest to 1 GiB.
-The fields `has_video`, `extractor`, `lang`, `quality` are always given highest priority in sorting, irrespective of the user-defined order. This behaviour can be changed by using `--force-format-sort`. Apart from these, the default order used is: `res,fps,codec,size,br,asr,proto,ext,has_audio,source,format_id`. Note that the extractors may override this default order, but they cannot override the user-provided order.

If your format selector is `worst`, the last item is selected after sorting. This means it will select the format that is worst in all repects. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-f best -S +size,+br,+res,+fps`.
$ youtube-dlc -S '+res'
# Download the smallest video available
-$ youtube-dlc -S '+size,+bitrate'
+$ youtube-dlc -S '+size,+br'
# Download best video available via the best protocol
# (https/ftps > http/ftp > m3u8_native > m3u8 > http_dash_segments ...)
-$ youtube-dlc -S 'protocol'
+$ youtube-dlc -S 'proto'
$ youtube-dlc -S '+res:480,codec,br'
```
+# PLUGINS
+Plugins are loaded from `<root-dir>/ytdlp_plugins/<type>/__init__.py`. Currently only `extractor` plugins are supported. Support for `downloader` and `postprocessor` plugins may be added in the future. See [ytdlp_plugins](ytdlp_plugins) for example.
