How to use splitmuxsink with multiple pipelines?

[pisymbol .]

Here is what I was using:

matroskamux name=muxer streamable=true ! multifilesink name=mfsink
post-messages=true next-file=5 max-file-duration=\"{}\" location=\"{}\"
.. ! h264parse ! queue ! muxer.video_0
.. ! h264parse ! queue ! muxer.video_1

Which works fine. But If I translate this to splitmuxsink, gst-launch
complains that it can't connect queue to muxer:

splitmuxsink name=muxer send-keyframe-requests=10000000000
muxer=matroskamux muxer-properties="properties,streamable=true"
max-size-time=\"{}\" location=\"{}\"
.. ! h264parse ! queue ! muxer.video_0
.. ! h264parse ! queue ! muxer.video_1

I've Googled extensively but I can't find an example of using splitmuxsink
with two different pipelines (this thread came the closest:

)
