Abstract
A video transcoding method includes: decoding a source video stream to obtain a first video frame and decoding information, and inserting watermark information into the first video frame to generate a second video frame; determining types of macroblocks in the second video frame based on the watermark information and the decoding information; for each macroblock, determining target encoding parameters required for encoding the macroblock based on the type of the macroblock and a rate distortion optimization (RDO) algorithm; and performing macroblock coding according to the target coding parameters of each macroblock, so as to generate a transcoded target video stream.
