Find frames in the DPB that are ready for output and either write them to the output FIFO or drop their output flag, depending on the value of discard.

Parameters

max_output	maximum number of AUs with an output-pending frame in at least one layer that can be present in the DPB before output is triggered
max_dpb	maximum number of any frames that can be present in the DPB for any layer before output is triggered
