Video encoding method, video decoding method, and related apparatuses

A video encoding method performed by an electronic device, the method comprising:

• determining a current video frame;
• determining a reference frame corresponding to the current video frame from video frames that have been encoded, and obtaining a target quantity of blocks that are encoded in a skip mode in the reference frame and a total block quantity of blocks in the reference frame;
• determining, according to a relationship between the target quantity and the total block quantity, a target resolution used for encoding the current video frame, further including:
• determining a first resolution as the target resolution for encoding the current video frame when a reciprocal of a ratio of the target quantity to the total block quantity is greater than or equal to a preset threshold;
• and
• determining a second resolution as the target resolution for encoding the current video frame when the reciprocal of the ratio of the target quantity to the total block quantity is less than the preset threshold, the second resolution being greater than the first resolution;
• and
• encoding the current video frame by using the target resolution and the reference frame.

An electronic device, comprising:

• a processor, a communication interface, a memory, and a communication bus;
• the processor, the communication interface, and the memory communicating with each other by using the communication bus, the communication interface being an interface of a communication module;
• the memory storing computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the electronic device to perform a plurality of operations including:
• determining a current video frame;
• determining a reference frame corresponding to the current video frame from video frames that have been decoded, and obtaining a target quantity of blocks that are decoded in a skip mode in the reference frame and a total block quantity of blocks in the reference frame;
