I want audio/ogg support in Media Source Extensions

Browsers can currently play audio/ogg; codec=opus files natively with audio elements, but that MIME is not consistently supported for Media Source Extensions (MSE). MSE can solve the problem of low-latency audio playback, and the Opus audio codec is one of best performing low-latency codecs available to us. Unfortunately, Ogg containers are the ones officially used for Opus files, and MSE does not support them.

The current work-around is to use third-party tools like FFMPEG to create WebM Opus files, which does not align with the Opus file standards and current Opus tools.
