The present invention provides a video mixing method, which includes: acquiring a plurality of first video frame frames from a first video terminal, acquiring a plurality of second video frame frames from a second video terminal; according to a preset alignment time length, setting Multiple picture frame alignment time stamp intervals; according to the first picture frame time stamp, determine the picture frame alignment time stamp interval of the first video picture frame; according to the second picture frame time stamp, determine the picture frame alignment time of the second video picture frame Stamp interval; align the first video frame and the second video frame in each frame alignment time stamp interval; perform video mixing on the first video frame and the second video frame after the alignment operation operate. The present invention also provides a video mixing device. The video mixing method and the video mixing device of the present invention avoid the picture asynchrony between the first video picture frame and the second video picture frame.
Description
technical field [0001] The invention relates to the field of video processing, in particular to a video mixing method, a video mixing device and a storage medium. Background technique [0002] With the development of science and technology, live video applications are favored by more and more users, among which interactive live broadcast is an important application in live video. In the interactive live broadcast, the host terminal and the mic-connected audience terminal will perform interconnection operations. If a third-party viewer wants to see the mic-connected scene, they need to perform a mixed stream operation on the video screen of the anchor terminal and the video screen of the mic-connected audience terminal. [0003] In the existing video mixing method, the server side generally performs a mixing operation on the video images of the anchor terminal and the video images of the audience terminals with mics. This mixing operation does not additionally increase the b...
