### Install required codecs
In this example, we'll be using x264 and opus as our video and audio codecs. Therefore, we need to make sure that these codecs are installed within our system.
Installation steps:
* [x264](https://github.com/pion/mediadevices#x264)
* [opus](https://github.com/pion/mediadevices#opus)
