In your implementation as mentioned above, there will be one queue for the OUTPUT buffer type and another queue for the CAPTURE buffer type right?
So if we have two Resizer outputs, then we would need two queues of the CAPTURE buffer type. When application calls QBUF, on the node, which queue will be used for the buffer? So this makes me believe we need to two capture nodes and one output node for this driver.
