Abstract
A method of decoding a coded video bitstream implemented by a video decoder is provided. The method includes the video decoder determining whether a gradual decoding refresh (GDR) picture in the coded video bitstream is an initial picture in decoding order or the initial picture following an end of sequence (EOS) network abstraction layer (NAL) unit in the decoding order; setting a flag to a value to prevent the GDR picture from being output when the GDR picture is the initial picture in decoding order or the initial picture following the EOS NAL unit in the decoding order; decoding the GDR picture; and storing the GDR picture in a decoded picture buffer (DPB).
