# EXTRACTOR ARGUMENTS
Some extractors accept additional arguments which can be passed using `--extractor-args KEY:ARGS`. `ARGS` is a `;` (colon) seperated string of `ARG=VAL1,VAL2`. Eg: `--extractor-args youtube:skip=dash,hls`
The following extractors use this feature:
* **youtube**
* `skip`: `hls` or `dash` (or both) to skip download of the respective manifests
# 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.
