1. A method of decoding implemented by a video decoder, comprising:
receiving, by the video decoder, a bitstream containing an external decoder refresh (EDR) picture and a list of pictures for the EDR picture, wherein the list of pictures lists pictures referred to by entries in a first reference picture list, pictures referred to by entries in a second reference picture list, and external pictures in increasing decoding order, and wherein a difference between picture order count values for any two consecutive pictures in the list of pictures is greater than one half of a negative of maximum picture order count least significant bits and less than one half of the maximum picture order count least significant bits;
obtaining, by the video decoder, an external picture from the external pictures referred to in the list of pictures; and
decoding, by the video decoder, the EDR picture using the external picture that was obtained.
