Same should work with opus because ogg is also an opus file container ( check
this link: http://en.wikipedia.org/wiki/Opus_(audio_format):   "Opus data
can be encapsulated in Ogg containers. The content of such Ogg Opus streams
should be specified as audio/ogg; codecs=opus and for Ogg Opus files the
.opus filename extension is recommended.[1] Support for encapsulation of
Opus in Matroska containers has been completed.[9] Opus is also allowed as a
registered format in MPEG-TS.[10]")

For me, with following commands, for example, I can record and playback opus
files:

RECORD:
gst-launch-1.0 autoaudiosrc ! audioconvert !
"audio/x-raw,rate=24000,channels=1" ! opusenc !  oggmux  ! filesink
location=input.opus

PLAYBACK:
gst-launch-1.0 filesrc location=input.opus ! oggdemux ! opusdec !
audioconvert ! alsasink
