An image encoding method and apparatus, a real-time communication method, a device, a storage medium, and a program product. The method includes: obtaining a first image frame in a video stream, encoding the first image frame into a first non-instantaneous decoding refresh (non-IDR) frame, and encoding a next image frame of the first image frame into an instantaneous decoding refresh (IDR) frame based on a determination, according to the first non-IDR frame, that a scene switch occurs.

A video encoding method includes obtaining a current image frame, performing video image enhancement on a target region in the current image frame, to generate an image-enhanced image frame, the target region including a region in which hopping occurs in a pixel value of a pixel in the current image frame, and encoding the image-enhanced image frame.

Video encoding method and apparatus, real-time communication method and apparatus, device, and storage medium

An encoding method includes pre-encoding a current video frame in a video stream, to obtain a pre-encoded current video frame, when there is no I frame in M encoded video frames that have been encoded before the current video frame, determining whether the current video frame is a scene switching frame in which scene switching has occurred relative to a previous video frame, based on the pre-encoded current video frame and a pre-encoded previous video frame to the current video frame, M being a preset positive integer, and encoding the current video frame into an I frame when the current video frame is the scene switching frame, and encoding the current video frame into a P frame when the current video frame is not the scene switching frame.

Encoding method, real-time communication method, apparatus, device, and storage medium

An image processing method and apparatus, a computer device, a storage medium and a program product, which can be applied to scenes such as image processing, game, and game basic skill. The method includes: encoding a current frame image to obtain an initial encoded image, and obtaining an encoding parameter, the encoding parameter comprising: a parameter indicating whether a scene switch exists in the current frame image; and recoding the current frame image based on a determination, according to the encoding parameter, that the current frame image needs to be recoded to obtain a target encoded image, wherein a data volume of the target encoded image is less than the data volume of the initial encoded image.
