Abstract

This disclosure relates to a method (500), software and device for encoding a video sequence into an encoded video stream having a target resolution, comprising: encoding (S502) a first image frame of the video sequence using the base layer to encode the image frame in a first resolution being lower than the target resolution, and using the enhancement layer to encode at least a portion of image data of the first image frame to reach the target resolution; detecting (S504) an encoding scenario from a set of one or more predefined encoding scenarios; and encoding (S506) a second image frame of the video sequence using the base layer to encode the second image frame in the target resolution, and indicating in the encoded video stream that the second image frame is decodable in the target resolution using only the base layer.
