Abstract
There is provided a method for decoding a picture included in a coded video bitstream. The method comprises obtaining a computational complexity indicator indicating complexity of a computation needed for decoding the coded video bitstream and providing to a decoder the computational complexity indicator associated with the coded video bitstream, wherein the obtained computational complexity indicator is configured to be used for determining whether one or more coding tools is allowed to be used for decoding the picture.
