Well, if they're running in the same process then they will modify the
default debug threshold of all things in that process.

Yes, the problem is that your pipeline sends a BYTE segment to opusdec,
but opusdec requires a TIME segment. You need to add some payloading
format before sending Opus over the network, also not just because of
GStreamer reasons.

Try adding oggmux before your tcpserversink and oggdemux after your
tcpcliensrc. Alternatively you could also use RTP, but to do that over
TCP (and not just UDP) you need to use the rtpstreampay/depay elements
from 1.3.
