Abstract
Encoding a group of frames of a video sequence can include determining a stillness of the group of frames, in response to determining that the stillness of the group of frames meets stillness conditions, encoding the group of frames using a coding structure that is a one-layer coding structure, and, in response to determining that the stillness of the group of frames does not meet the stillness conditions, encoding the group of frames using the coding structure that is a multi-layer coding structure. Instructions for decoding a group of frames include instructions to determine, from an encoded bitstream, an indication of a coding structure used to encode the group of frames, receive the group of frames in a coding order of the coding structure, and decode the group of frames using the coding structure. The indication is one of a one-layer coding structure indication or a multi-layer coding structure indication.
