Abstract
A method for determining a sample adaptive offset mode includes: obtaining a motion vector included in a first coding tree block, and obtaining a reference frame of a video frame of the first coding tree block; obtaining a video resolution and a frame rate, calculating a threshold based on the video resolution and the frame rate; if it is determined that the motion vector is not greater than the threshold, determining a second coding tree block based on the motion vector; determining whether an offset mode is trusted; and if the offset mode is trusted, obtaining offset modes of all second coding blocks, and using obtained all types of offset modes as offset modes of the first coding tree block.
