Issue with the end of the pipeline using rtpopuspay

Jack
Hello,

I have this pipeline working well now :

gst-launch-1.0 -v filesrc location=17seconds48000D.wav ! wavparse !
deinterleave name=d
d.src_0 ! queue ! volume name="vol0" volume=0.5 ! audiopanorama
name="pan0" panorama=-1 ! audio/x-raw,channels=2 ! deinterleave name=d0
d.src_1 ! queue ! volume name="vol1" volume=0.5 ! audiopanorama
name="pan1" panorama=-1 ! audio/x-raw,channels=2 ! deinterleave name=d1
d0.src_0 ! queue ! mix0.
d0.src_1 ! queue ! mix1.
d1.src_0 ! queue ! mix0.
d1.src_1 ! queue ! mix1.
audiomixer name=mix0 ! i.sink_0
audiomixer name=mix1 ! i.sink_1
interleave name=i ! opusenc ! oggmux ! filesink location=output.ogg


And this one failed :

gst-launch-1.0 -v filesrc location=17seconds48000D.wav ! wavparse !
deinterleave name=d
d.src_0 ! queue ! volume name="vol0" volume=0.5 ! audiopanorama
name="pan0" panorama=-1 ! audio/x-raw,channels=2 ! deinterleave name=d0
d.src_1 ! queue ! volume name="vol1" volume=0.5 ! audiopanorama
name="pan1" panorama=-1 ! audio/x-raw,channels=2 ! deinterleave name=d1
d0.src_0 ! queue ! mix0.
d0.src_1 ! queue ! mix1.
d1.src_0 ! queue ! mix0.
d1.src_1 ! queue ! mix1.
audiomixer name=mix0 ! i.sink_0
audiomixer name=mix1 ! i.sink_1
interleave name=i ! opusenc ! rtpopuspay pt=96 ! fakesink


As you can see, only the end of the pipeline change "rtpopuspay pt=96 !
fakesink" instead of "oggmux ! filesink location=output.ogg".

A recommandation to make the pipeline with rtpopuspay working ?
