Mediabunny is a library for reading, writing, and converting video and audio files using the WebCodecs API. I think it would be a great fit for Etro and could open up a lot of very cool possibilities. It would be a solution for offline recording #115 and could be used to improve seeking performance and frame accuracy. As I'm building web based video editing tools that could benefit from this integration, I'm very interested in contributing to getting this work done.
