1. A method of decoding comprising:
obtaining a picture in video data, wherein the picture is associated with a 360-degree video;
determining that the picture comprises a plurality of faces;
based on the determination that the picture comprises the plurality of faces, identifying a first face in the picture to which a current sample belongs to;
determining that the current sample is located at a boundary of the first face;
based on the determination that the current sample is located at the boundary of the first face, identifying a second face in the picture, wherein the second face shares the boundary of the first face;
identifying a sample in the second face for predicting the current sample, wherein the sample in the second face is available for predicting the current sample is determined based on a coding order, wherein the coding order comprises at least one of a first coding order, a second coding order, or a third coding order, wherein the first coding order is from left to right direction relative to the current sample, wherein the second coding order is from top to bottom direction relative to the current sample, and wherein the third coding order is left to right and top to bottom direction relative to the current sample;
determining that the identified sample in the second face is available; and
based on the determination that the sample in the second face is available, predicting the current sample using the sample from the second face.
