Neat!

The codec is to encode then? Are you teeing out after it then, and thus
saving lossy data via the decoding arm of the pipeline?

In any case what I think you want is to keep everything in the pipeline,
and just relink the tee connections to the muxer and decoder (why not a
direct raw sink?). You want to do a gst_pad_set_blocked while doing the
link, and I think you'll have to push out a newsegment event on the
sinks as well -- not sure. But yes, it is possible.
