Video encoding method, video playback method, related device, and medium

An encoding method includes capturing an original screen video to be encoded, the original screen video including frames of screen images, reading image feature parameters of the frames of screen images in the original screen video, determining video encoding parameters for the original screen video according to the image feature parameters, acquiring a screen display resolution of a screen sharing object, and encoding the original screen video according to the video encoding parameters and with reference to the screen display resolution of the screen sharing object.

Encoding method and apparatus for screen sharing, storage medium, and electronic device

This application relates to a method and an apparatus for processing encoded data, a computer device, and a storage medium. The method includes: obtaining a to-be-encoded data frame; determining a complexity of the to-be-encoded data frame, the complexity representing at least a spatial texture complexity and a temporal motion intensity; obtaining a real-time encoding bit rate, the real-time encoding bit rate being an encoding bit rate of a previous encoded data frame of the to-be-encoded data frame; and adjusting an encoding parameter according to the real-time encoding bit rate and the complexity of the to-be-encoded data frame. The encoding parameter is adjusted according to the real-time encoding bit rate and the complexity, and different real-time encoding bit rates and complexities may correspond to different encoding parameters. In this way, the encoding parameter is applicable to different scenes, thereby achieving high adaptability.

Method and apparatus for processing encoded data, computer device, and storage medium

A picture file processing method, apparatus, and computer readable medium are provided. The method includes parsing a picture file, to obtain a picture header information data segment, first stream data, and second stream data of a first image thereof. The first stream data of the first image is decoded to generate red-green-blue (RGB) data of the first image. The second stream data of the first image is decoded to generate Alpha data of the first image. Red-green-blue-alpha (RGBA) data corresponding to the first image are generated according to the RGB data and the Alpha data.

Image file processing method, system and storage medium

Embodiments of this application disclose an image transcoding method performed at a computing device. The image transcoding method includes: obtaining a source image quality parameter of a source image, the source image being a to-be-transcoded image, and the source image quality parameter being associated with a source image format and used for indicating image quality of the source image; obtaining, according to the source image quality parameter and a preset mapping relationship, a target image quality parameter that is associated with a target image format and that corresponds to the source image quality parameter of the source image; and transcoding the source image in the source image format according to the target image quality parameter to obtain a target image in the target image format.
