Topic: Opus support in SVPtube?

I just noticed that SVPtube uses Vorbis audio for VP9 video streams rather than Opus.  For the last year or so, YouTube will use Opus audio by default (fmt251 for HD videos) and will only use Vorbis as a fallback.

Seeing how YouTube's Opus encodes are of better audio quality and is even the default audio format, I hope it isn't blasphemous to suggest implementing support for it.
