Restart recording tee branch

[Maobuff]

I'm trying to implement splitting record files with such a pipeline
source->tee->queue1->encoder->filesink
->queue2->visualization
Previously I used add_probe on the src pad of tee with GST_PAD_PROBE_TYPE_IDLE to unlink it from sinkpad of queue1 and send eos to the encoder. Then i have to catch element msg on the bus from filesink to properly close the queue1 branch.
I can't see a way to pass the encoder element to add_probe callback. How to properly implement such a task in rust.
