* **[SponsorBlock Integration](#sponsorblock-options)**: You can mark/remove sponsor sections in YouTube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API
* When `--embed-subs` and `--write-subs` are used together, the subtitles are written to disk and also embedded in the media file. You can use just `--embed-subs` to embed the subs and automatically delete the separate file. See [#630 (comment)](https://github.com/yt-dlp/yt-dlp/issues/630#issuecomment-893659460) for more info. `--compat-options no-keep-subs` can be used to revert this
* `certifi` will be used for SSL root certificates, if installed. If you want to use system certificates (e.g. self-signed), use `--compat-options no-certifi`
* yt-dlp's sanitization of invalid characters in filenames is different/smarter than in youtube-dl. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
-* yt-dlp tries to parse the external downloader outputs into the standard progress output if possible (Currently implemented: `aria2c`). You can use `--compat-options no-external-downloader-progress` to get the downloader output as-is
+* yt-dlp tries to parse the external downloader outputs into the standard progress output if possible (Currently implemented: [~~aria2c~~](https://github.com/yt-dlp/yt-dlp/issues/5931)). You can use `--compat-options no-external-downloader-progress` to get the downloader output as-is
For ease of use, a few more compat options are available:
--prefer-insecure Use an unencrypted connection to retrieve
information about the video (Currently
supported only for YouTube)
- --add-header FIELD:VALUE Specify a custom HTTP header and its value,
+ --add-headers FIELD:VALUE Specify a custom HTTP header and its value,
separated by a colon ":". You can use this
option multiple times
--bidi-workaround Work around terminals that lack
* `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.

-Most likely, you'll want to use various options. For a list of options available, have a look at [`yt_dlp/YoutubeDL.py`](yt_dlp/YoutubeDL.py#L180).

**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)
