Description
When performing a decode to a file, the decode process fails with Mesa drivers because the mesa driver use 2 different queue to perform the decode and the transfer to buffer.
Need to use a process filter to perform the transfer with --enablePostProcessFilter 0

Research direction
Start with the VKVS decode-to-file path and trace how the --enablePostProcessFilter 0 option affects transfer and decode queue selection under Mesa drivers. Reproduce the failure with a decode-to-file run, then verify that transfer and decode work when separate queues are required.
