All public classes with a name ending in `IE` are imported from each file. 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`)
|
||||
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`).
|
||||
Due to the mechanics behind this, you should exclude the subclass extractor from being imported separately by making it private using one of the methods described above.

If you are a plugin author, add [yt-dlp-plugins](https://github.com/topics/yt-dlp-plugins) as a topic to your repository for discoverability
