Abstract: Embodiments of the present invention disclose a video decoding method, where the method includes: respectively converting a transform unit and a prediction unit that are obtained after decoding of a video compression bitstream into an M×M residual block and an M×M prediction block, where M=16, 8, or 4, and the video compression bitstream includes any one of an HEVC bitstream, a VP9 bitstream, and an AVS2.0 bitstream; obtaining a reconstructed picture block according to the residual block and the prediction block; and obtaining a decoded reconstructed picture by performing filtering on the reconstructed picture block. The embodiments of the present invention further disclose a video decoder. The present invention is used to reduce module development of a multi-protocol video decoder and reduce dimensions and power consumption of the video decoder.
