...and I guessed wrong: Simply adding build-dependency makes autotools 
detect it but isn't really used for anything, apparently.

A patch exist to implement Opus transcoding support.  That patch is not 
adopted upstream due to fear of patent trolls.

Please apply it for Debian redistribution, where we evidently do not 
have same concerns¹ (we distribute Opus encoders already).

Patch attached.  Patch also attached from same source (but can be 
applied independently) for read/write support for vp8 codec.
