视频编解码器的编码方法和解码方法
摘要：
本发明实施例提供了一种视频编解码器的编码方法和解码方法。所述视频编解码器的编码方法，包括：获取当前待编码图像以及所述当前待编码图像的前一帧的已编码图像对应的前一帧已编码图像对应的构建参考帧；根据所述已编码图像更新所述前一帧已编码图像对应的构建参考帧，将更新后的所述前一帧已编码图像对应的构建参考帧作为所述当前待编码图像对应的当前待编码图像对应的构建参考帧；将所述当前待编码图像对应的当前待编码图像对应的构建参考帧作为参考图像，对所述当前待编码图像进行编码。本发明能够提高编解码性能。
摘要（英）：

The invention provides a coding method and a decoding method for a video codec. The coding method comprises steps that a present to-be-coded image and a construction reference frame corresponding to a previous coded image of the present to-be-coded image are acquired; the construction reference frame corresponding to the previous coded image is updated according to the coded image, the construction reference frame corresponding to the previous coded image after update is taken as a construction reference frame corresponding to the present to-be-coded image; the construction reference frame corresponding to the present to-be-coded image is taken as a reference image, and the present to-be-coded image is coded. The coding method is advantaged in that coding and decoding performance can be improved.
