Abstract: A video processing method is provided. In the method, at least one pair of decoded blocks to be reconstructed in a video frame is determined. Each pair of decoded blocks in the at least one pair of decoded blocks includes a first decoded block of a first resolution and a second decoded block of a second resolution. The first decoded block is adjacent to the second decoded block. The first resolution of the first decoded block is adjusted to a target resolution. The second resolution of the second decoded block is adjusted to the target resolution. A first edge pixel set in the first decoded block is determined. A second edge pixel set in the second decoded block is determined, the second edge pixel set being adjacent to the first edge pixel set. Further, the first edge pixel set and the second edge pixel set are filtered.

Abstract: A video decoding method includes obtaining a current video frame and determining a region of interest (ROI) of the current video frame. The method also includes decoding the ROI by using a first resolution, and decoding at least other regions of the current video frame than the ROI by using second resolutions, the first resolution being higher than the second resolution.

Abstract: Disclosed is a video decoding method, including: obtaining a current video frame, the current video frame being partitioned into a plurality of regions; obtaining a syntax element carried in syntax data corresponding to each of the plurality of regions, the syntax element being used for indicating a resolution used to decode the region, and a plurality of resolutions used to decode the plurality of regions including at least two different resolutions; and decoding the each of the plurality of regions by using the resolution corresponding to the region. The plurality of resolutions are determined according to a transmission bandwidth of a video stream including the current video frame from a source to a destination, e.g., by comparing the transmission bandwidth with a preset bandwidth threshold.
