Abstract
A video coding method includes: obtaining a first video file and a second video file that are different; separately decoding the first video file and the second video file to obtain first information of a first image block in the first video file and second information of a second image block in the second video file; obtaining, based on the first information and the second information, difference information indicating a difference between the first information and the second information; and encoding the difference information to obtain encoded data. The difference information may be used to replace an original decoding result in the second video file. It is equivalent to reducing storage resources for video storage and bandwidth for video transmission while ensuring that the complete second video file can be restored.
