<p>The embodiments in the present invention relate to a video encoding method and device, a video decoding method and device, wherein the encoding method includes: acquiring interpolation filtering coefficients according to the video frames; performing, according to the interpolation filtering coefficients, a macro-block down sampling decomposition intra-frame encoding to the video frames, wherein in the process of the interpolation in the macro-block down sampling decomposition intra-frame encoding, the interpolation filtering coefficients are used. The video encoding method and device, the video decoding method and device provided in embodiments of the present invention acquire interpolation filtering coefficients through video frames, and perform the macro-block down sampling decomposition intra-frame encoding to the video frames according to the interpolation filtering coefficients, because each video frame has the corresponding interpolation filtering coefficients, thus in the process of performing the interpolation in the macro-block down sampling decomposition intra-frame encoding to the video frames, an adaptive interpolation to the macro-block of video frame with interpolation filtering coefficients according to the variable image content of the video frame is implemented, and the video encoding compress efficiency is increased by the method of the adaptive interpolation.</p> |
