Video processing method and system and related device

摘要

A video processing method and system and a related device are disclosed, an encoder sends a method for compressing a pixel value of a video image to a decoder, the method includes a mapping between a pixel value of the video image before compression and a pixel value of the video image after the compression; compressing, by the encoder according to the method for compressing a pixel value, the pixel value of the video image to obtain a video image to be encoded; encoding, by the encoder, the video image to be encoded to obtain a video image encoded stream; and sending, by the encoder, the video image encoded stream to the decoder, the decoder receives and decodes the video image encoded stream to obtain a decoded video image, and decompresses a pixel value of the decoded video image to restore the pixel value of the video image before compression.

1. A video processing method, comprising:
sending, by an encoder, a method for compressing a pixel value of a video image to a decoder, wherein the method for compressing the pixel value comprises a mapping between a pixel value of the video image before compression and a pixel value of the video image after the compression; compressing, by the encoder, the pixel value of the video image according to the method for compressing a pixel value of the video image to obtain a video image to be encoded; encoding, by the encoder, the video image to be encoded to obtain a video image encoded stream; and sending, by the encoder, the video image encoded stream to the decoder, so that the decoder receives and decodes the video image encoded stream to obtain a decoded video image and then decompresses a pixel value of the decoded video image according to the method for compressing the pixel value of the video image to restore the pixel value of the video image before compression from the pixel value of the decoded video image, wherein the sending, by the encoder, the method for compressing the pixel value of the video image to the decoder comprises: sending, by the encoder, an identity ID of the method for compressing the pixel value of the video image to the decoder, wherein different identity IDs represent different methods for compressing the pixel value of the video image.
