Video Encoding Decoding Method and Device and Video Codec

A video encoding decoding method and device and a video codec are provided. The video encoding method includes: the first view picture is basic layer encoded as a reference view picture, the predication information is extracted in combination with the second view picture and the second view picture is re-created; the residual value is calculated based on the re-created view picture and original second view picture; when the residual value is larger than a threshold, both residual value and predication information are enhanced layer encoded simultaneously, otherwise, only the predication information is enhanced layer encoded; the encoded information is obtained by multiplexing the enhanced layer encoding with the basic layer encoding of the first video picture. The video decoding method includes: after de-multiplex, the basic layer encoded information and the enhanced layer encoded information are decoded respectively to obtain the first view picture, prediction information and residual value, and then the second view picture is re-created. The embodiments of the invention can realize the effective compression of the stereo video data, reduce the encoding complexity and are compatible with the conventional two dimensional displaying, so as to correctly and easily re-create a stereo view picture.
