Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:
+* yt-dlp supports only [Python 3.7+](## "Windows 7"), and *may* remove support for more versions as they [become EOL](https://devguide.python.org/versions/#python-release-cycle); while [youtube-dl still supports Python 2.6+ and 3.2+](https://github.com/ytdl-org/youtube-dl/issues/30568#issue-1118238743)
* The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
* `avconv` is not supported as an alternative to `ffmpeg`
* yt-dlp stores config files in slightly different locations to youtube-dl. See [CONFIGURATION](#configuration) for a list of correct locations
For other third-party package managers, see [the wiki](https://github.com/yt-dlp/yt-dlp/wiki/Installation#third-party-package-managers) or refer their documentation
+<a id="update-channels"/>
+
+There are currently two release channels for binaries, `stable` and `nightly`.
+`stable` releases are what the program will update to by default, and have had many of their changes tested by users of the master branch.
+`nightly` releases are built after each push to the master branch, and will have the most recent fixes and additions, but also have the potential for bugs.
+The latest `nightly` is available as a [pre-release from this repository](https://github.com/yt-dlp/yt-dlp/releases/tag/nightly), and all `nightly` releases are [archived in their own repo](https://github.com/yt-dlp/yt-dlp-nightly-builds/releases).
+
+When using `--update`/`-U`, a release binary will only update to its current channel.
+This release channel can be changed by using the `--update-to` option. `--update-to` can also be used to upgrade or downgrade to specific tags from a channel.
+
+Example usage:
+* `yt-dlp --update-to nightly` change to `nightly` channel and update to its latest release
+* `yt-dlp --update-to stable@2023.02.17` upgrade/downgrade to release to `stable` channel tag `2023.02.17`
+* `yt-dlp --update-to 2023.01.06` upgrade/downgrade to tag `2023.01.06` if it exists on the current channel

+### Forking the project
+If you fork the project on GitHub, you can run your fork's [build workflow](.github/workflows/build.yml) to automatically build the selected version(s) as artifacts. Alternatively, you can run the [release workflow](.github/workflows/release.yml) or enable the [nightly workflow](.github/workflows/release-nightly.yml) to create full (pre-)releases.

* `yt-dlp.conf` in the home path given by `-P`
* If `-P` is not given, the current directory is searched
1. **User Configuration**:
+ * `${XDG_CONFIG_HOME}/yt-dlp.conf`
* `${XDG_CONFIG_HOME}/yt-dlp/config` (recommended on Linux/macOS)
* `${XDG_CONFIG_HOME}/yt-dlp/config.txt`
- * `${XDG_CONFIG_HOME}/yt-dlp.conf`
+ * `${APPDATA}/yt-dlp.conf`
* `${APPDATA}/yt-dlp/config` (recommended on Windows)
* `${APPDATA}/yt-dlp/config.txt`
* `~/yt-dlp.conf`
- `source`: The preference of the source
- `proto`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8_native`/`m3u8` > `http_dash_segments`> `websocket_frag` > `mms`/`rtsp` > `f4f`/`f4m`)
- `vcodec`: Video Codec (`av01` > `vp9.2` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other)
- - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` `ac4` > > `eac3` > `ac3` > `dts` > other)
+ - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac4` > `eac3` > `ac3` > `dts` > other)
- `codec`: Equivalent to `vcodec,acodec`
- `vext`: Video Extension (`mp4` > `mov` > `webm` > `flv` > other). If `--prefer-free-formats` is used, `webm` is preferred.
- `aext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other). If `--prefer-free-formats` is used, the order changes to `ogg` > `opus` > `webm` > `mp3` > `m4a` > `aac`
Some extractors accept additional arguments which can be passed using `--extractor-args KEY:ARGS`. `ARGS` is a `;` (semicolon) separated string of `ARG=VAL1,VAL2`. E.g. `--extractor-args "youtube:player-client=android_embedded,web;include_live_dash" --extractor-args "funimation:version=uncut"`
+Note: In CLI, `ARG` can use `-` instead of `_`; e.g. `youtube:player-client"` becomes `youtube:player_client"`
+
The following extractors use this feature:
#### youtube
* `${XDG_CONFIG_HOME}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Linux/macOS)
* `${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
* `${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Windows)
+ * `${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
* `~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/`
* `~/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
* **System Plugins**
All public classes with a name ending in `IE`/`PP` are imported from each file for extractors and postprocessors repectively. This respects underscore prefix (e.g. `_MyBasePluginIE` is private) and `__all__`. Modules can similarly be excluded by prefixing the module name with an underscore (e.g. `_myplugin.py`).
-To replace an existing extractor with a subclass of one, set the `plugin_name` class keyword argument (e.g. `MyPluginIE(ABuiltInIE, plugin_name='myplugin')` will replace `ABuiltInIE` with `MyPluginIE`). Since the extractor replaces the parent, you should exclude the subclass extractor from being imported separately by making it private using one of the methods described above.

**Tip**: If you are porting your code from youtube-dl to yt-dlp, one important point to look out for is that we do not guarantee the return value of `YoutubeDL.extract_info` to be json serializable, or even be a dictionary. It will be dictionary-like, but if you want to ensure it is a serializable dictionary, pass it through `YoutubeDL.sanitize_info` as shown in the [example below](#extracting-information)
