Abstract

A device may be configured to decode video data based on information included in a generative face video information message. In one example, a generative face video information message includes a flag indicating whether coordinate information of keypoints is present in the generative face video information message. In one example, the generative face video information message conditionally includes a flag indicating whether a number of matrices for a matrix type is equal to an indicated number of keypoints. In one example, a value of the flag indicating whether a number of matrices for a matrix type is equal to the indicated number of keypoints may be inferred when not present.
