The embodiment of the application provides a video live broadcasting method. The live broadcasting method comprises the steps of acquiring a video frame image, and carrying out the live broadcasting by the video frame image; when the video frame image is not acquired within a preset time interval, obtaining a prediction image to carry out the live broadcasting, wherein the prediction image is generated in the following manners of obtaining a background image and an object contour image in the video frame image which is acquired before the current time, wherein the object contour image has the corresponding coordinate information, and generating the prediction image by the background image, the object contour image and the coordinate information of the object contour image. According to the embodiment of the application, when a server is off-line or the video frame image in the server is lost, the video frame image acquired previously is used to generate the prediction image, and the prediction image is used to carry out the live broadcasting, so that a live broadcasting picture still looks like an image changing continuously, a picture jump situation is avoided, and the watching feelings of users are guaranteed.
Description
technical field [0001] The present application relates to the technical field of live video broadcasting, and in particular, to a live video live broadcast method, a terminal video live broadcast method, a video live broadcast device, and a terminal video live broadcast device. Background technique [0002] At present, live video broadcasts are generally realized through cameras, servers, and playback boxes. The camera captures video frame images, and then the video frame images are sent to the server in video stream format, and the server forwards the video stream to each playback box, and the playback box performs live broadcast according to the video stream. [0003] When the server is offline or the video frame image in the server is lost, the live screen of the playback box will stop or display a specific offline image. When the video frame image reception resumes, the live image will change from the stopped image or a specific offline image to the restored video frame...
