Abstract

The invention provides a video reading method, device, electronic equipment and storage medium, which are applied in the technical field of three-dimensional display. The method includes: when at least two video streams are played at the same time, obtaining the cache block number of the video to be played, wherein the at least two video streams correspond to at least two buffers respectively, and the cache blocks in the at least two buffers correspond one-to-one, and The cache blocks corresponding to each other in at least two buffers have the same cache block number; query the cache block address of each video stream corresponding to the cache block number in the cache block address list; in the buffer corresponding to each video stream , read and output the video frame from the cache block indicated by each cache block address, and the timing of the video frame stored in each cache block corresponding to the single cache block number is the same. In this way, when synchronizing at least two video streams, a large number of calculations can be avoided, processing complexity can be reduced, the synchronization process can be simplified, and the real-time performance and alignment accuracy of video synchronization can be improved.

Description

technical field [0001] The present invention is applied to the technical field of three-dimensional display, and particularly relates to a video reading method, device, electronic device and storage medium. Background technique [0002] With the maturity of 3D (Three Dimensions, three-dimensional display) display technology, 3D display technology is applied to the field of medical imaging, and the related way of viewing 3D medical images is realized by users wearing 3D endoscopes. [0003] The viewing principle of 3D endoscope is that the left and right eyes of a person receive the left and right video images played in frame order, and then the brain synthesizes the left and right video images to produce a three-dimensional effect. When watching movies, the left and right eyes need to receive video images through the 3D endoscope, so that the left-eye video frames of the left-eye video stream composed of left-eye images can only be received by the left eye, and the right-eye...
