I assume mainpipeline is a GstPipeline while pipeline1 and pipeline2 are
plain bins?

Sending the event to a pipeline/bin will send the event to all sinks (or
bins with sinks in them) so both pipelines should receive the event.

The best way to do this is to simply put the two separate pipelines into
two separate GstPipeline objects and work from there.
