Abstract

The invention discloses a transmission method and device for network self-adaptive video stream. Wherein, the method includes: encoding the target video stream to be transmitted to obtain a target frame sequence; determining some frames in the target frame sequence as specified frames, wherein the reference frame of the specified frame is the target frame sequence located in front of the specified frame frame and subsequent frames, the specified frame is not used as a reference frame for other frames in the target frame sequence; the target frame sequence is transmitted to the target device through the target network, wherein, when the target network is congested, the specified frame in the target frame sequence is discarded Some or all of the frames. The invention solves the technical problem that the self-adaptive scheme adopted in the related art under the condition of network transmission congestion reduces the video encoding bit rate and simultaneously reduces the user's video viewing quality and interactive experience.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and device for transmitting network adaptive video streams. Background technique [0002] Existing mainstream video coding algorithms (H.264 / H.265 / H.266 / AV1 / VP9), etc., the default video coding GOP sequence (I / P / B frame) will provide reference for other types of frames in the sequence, frame Mutual reference improves the encoding and compression efficiency. A frame only needs to save the difference between itself and the referenced frame, but the mutual reference mode will lead to error continuation propagation, that is, x frame error, refer to its y frame If there is an error, then the z frame that refers to the y frame will also have an error, and so on. If there is a frame discard during video transmission and playback, the decoding of the encoded frame with the reference discarded frame will fail, resulting in a black screen, missing blocks, and skipping. frame and ...
