Problems solved by technology

The decoded image with annotation information received by the sender has a certain loss of clarity, and the image with annotation is transmitted from the receiver to the video sender through the network. The speed of this process depends on the current network transmission Therefore, the transmission speed is affected, and there is a delay phenomenon, which is not conducive to the real-time interaction between the two parties

Abstract

The present application aims to provide a method and device for labeling video frames in real time. The method specifically comprises: sending a video stream to a second user equipment; receiving second frame related information of a second video frame intercepted by the second user equipment in the video stream; determining a first video frame corresponding to the second video frame in the video stream according to the second frame related information; receiving labeling operation information of the second video frame by the second user equipment; and displaying a corresponding labeling operation on the first video frame in real time according to the labeling operation information. According to the present application, labeling information is directly displayed in overlapping fashion on a non-coded or non-decoded video frame image sent by a video sender, and because the labeled video frame is not subjected to operations such as coding and decoding, the definition is high. Furthermore, this solution can also achieve real-time display of the label, so that the practicability is good, the interactivity is high, and the user experience and the broadband utilization rate are improved.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a technology for real-time labeling of video frames. Background technique [0002] In the current common video stream transmission method, the sender of the video stream encodes the video according to the encoding protocol and sends it to the video receiver through the network. The receiver receives the corresponding video, decodes the video, takes a screenshot of the decoded video, and Mark on the screen, encode the marked image and send it to the video sender through the network, or send the marked image to the server, and the video sender will receive the marked image added by the server. The decoded image with annotation information received by the sender has a certain loss of clarity, and the image with annotation is transmitted from the receiver to the video sender through the network. The speed of this process depends on the current network transmission Therefore, t...
