Reply To: What is Video Player Inputs Stream Adaptive add-on?

I’m not sure. But, I do know that it’s in the official Kodi add-on repository, so it’s safe. It looks like it’s a dependency for streaming add-ons so they can handle “adaptive streams”.

Adaptive streaming (also known as adaptive bitrate streaming) is a technology designed to deliver video to the user in the most efficient way possible and in the highest usable quality for each specific user.
