Queues empty even when stream is inactive

[Steve W]

Hello all

I’m trying to switch between two queues using input-selector:

input-selector name=i sync-streams=true sync-mode=clock cache-buffers=true
… ! queue max-size-time=0 name=q1 ! i.
… ! queue max-size-time=0 name=q2 ! i.
i. ! fakesink

I’ve added buffer probes to the sources of q1 and q2. Even when the input-selector has the active pad set to one stream, both of the buffer probes are triggered. Regardless of the duration rolled, current-level-buffers is always 0 for both q1 and q2. It seems to suggest that both queues are consumed even when the active pad is set to only one stream. Does anyone know why this might be the case?

Thanks
