Abstract
Video coding methods, apparatuses, and non-transitory computer readable mediums are provided. The method includes: obtaining a list of reference pictures comprising a plurality of pictures stored in a buffer, where the plurality of pictures comprise at least a first picture with a first spatial resolution, and a second picture with a second spatial resolution different from the first spatial resolution; obtaining a reference picture from the list of reference pictures; predicting a current picture by using the reference picture with its original spatial resolution without ensuring the reference picture to have a same spatial resolution as the current picture; and generating a bitstream based on a predicted current picture.
