That's more or less what needs to be done, yes. Typically queued source
buffers are passed on to the hardware, and once the hardware signals that
it has parsed enough to know the source format, you would configure everything
like is done below.

You probably also have to implement the job_ready m2m_op to check if this state
has been reached. If not, the job isn't ready yet.
