Abstract: In a video encoding method, a to-be-encoded video is obtained. The video includes at least two video frames arranged in sequence. A quantization parameter and a quantization parameter threshold of an ith video frame is calculated, where i is a positive integer greater than or equal to 2. A coding resolution of the ith video frame is determined according to the quantization parameter and the quantization parameter threshold. The coding resolution is a first coding resolution in a case that the ith video frame is sampled, and the coding resolution is a second coding resolution in a case that the ith video frame is downsampled. Then the ith video frame is encoded at the coding resolution.

Abstract: Embodiments of this application disclose a picture transmission method performed at a computer device. After obtaining a picture, the computer device generates a video sequence by replicating the picture N times, and N being a positive integer. Next the computer device obtains a resolution setting sequence and encodes the N to-be-encoded pictures in the video sequence according to the resolution setting sequence to generate N encoded pictures, each encoded picture having an associated resolution setting. Finally, the computer device sends the N encoded pictures to a decoding computer device. The decoding computer device then decodes and displays the N encoded pictures according to their respective resolution settings from low to high.
