a receiver configured to receive a coded video bitstream;
a processor coupled to the receiver and configured to determine:
whether a value for a first flag is set by an external input;
set the first flag equal to the value provided by the external input and a second flag equal to the first flag to prevent a gradual decoding refresh (GDR) picture from being output when the value for the first flag is provided by the external input, wherein the coded video bitstream comprises a sequence of access units (AUs) that comprise, in decoding order, a GDR AU, including the GDR picture with the second flag equal to one, and subsequent AUs; and
decode the GDR picture; and

a memory coupled to the processor and configured to store the GDR picture in a decoded picture buffer (DPB).
