Opus is a great format made for streaming. Please start supporting streaming in opus or at least convert to mp3 or other format. As it is now just won't play individual tracts or play webm video with opus audio. Also run Plex on same server and it will either convert and play audio or stream directly depending on device. Plex always converts webm video. Emby unfortunately wont stream either format or convert them to another.   Thank you.
