Description[edit]

This can only be used when MVDSTD:SetupOutputBuffers was previously used.

If a certain state flag is zero, this first writes a 0x10-byte entry into the global table used by MVDSTD:SetupOutputBuffers with entry_index=total_entries, then that flag is set.

This verifies that cur_outaddrX(converted to physaddr) matches the state data for entry0 which originated from MVDSTD:SetupOutputBuffers. Then those two addrs in state are overwritten with new_outaddrX(converted to physaddr).
