Subject: [PATCH] Small updates for Opus and metadata

Forcibly add the track and title metadata to the audio stream.  Fixes missing meta-data with Plex and possibly other programs.
Use the .opus file extension and ogg container for opus files to match recommended practice, and correct detection of opus files in Plex and other programs
