Abstract:
An example method of decoding video data includes receiving a plurality of pictures, receiving, in a message associated with a first picture of the plurality of pictures, information indicating a picture order count (POC) value of a recovery point picture of a gradual decoder refresh (GDR) set, when a picture that follows the first picture in decoding order has the POC value that is equal to a POC value of the recovery point picture, identifying the picture having the POC value equal to the POC value of the recovery point picture, as a recovery point picture, and when none of the pictures that follow the first picture has the POC value that is equal to the POC value of the recovery point picture, identifying one of the pictures that has a POC value greater than the POC value of the recovery point picture as the recovery point picture.
