Transcoding method and apparatus, and electronic device

Abstract

A transcoding apparatus including a decoder and an encoder is disclosed. The decoder is configured to: receive a first bitstream output by an application; decode the first bitstream to obtain a first image and first format information of the first image; embed the first format information into the first image to obtain a second image; and send the second image to the application. The encoder is configured to: receive a third image output by the application, where the third image is the second image or an edited version of the second image that is modified by the application; determine second format information based on the third image; obtain preconfigured third format information; perform format conversion on the third image based on the second format information and the third format information to obtain a fourth image; encode the fourth image to obtain a second bitstream; and send the second bitstream to the application.

Dependencies are inferred from the claim text.
