You should probably also combine those two separate pipelines into one.
Just set an appsink caps=video/x-raw-whatever,...  on playbin, and use
appsink instead of fakesink, or make a little GstBin with capsfilter
caps=... ! fakesink and a sink ghost pad, if you prefer to use fakesink.
Then the converters in playbin will do the right thing and you'll save
the overhead/delay of feeding things into the second pipeline.
