-Plugins provide elements that you can use in your pipeline. Each plugin lives in a `membrane_X_plugin` repository, where X can be a protocol, codec, container or functionality, for example [mebrane_opus_plugin](https://github.com/membraneframework/membrane_opus_plugin). Plugins wrapping a tool or library are named `membrane_X_LIBRARYNAME_plugin` or just `membrane_LIBRARYNAME_plugin`, like [membrane_mp3_mad_plugin](https://github.com/membraneframework/membrane_mp3_mad_plugin). Plugins are published on [hex.pm](https://hex.pm), for example [hex.pm/packages/membrane_opus_plugin](https://hex.pm/pakcages/membrane_opus_plugin) and docs are at [hexdocs](https://hexdocs.pm), like [hexdocs.pm/membrane_opus_plugin](https://hexdocs.pm/membrane_opus_plugin). Some plugins require native libraries installed in your OS. Those requirements, along with usage examples are outlined in each plugin's readme.
