Title:
VIDEO READING METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/103954
Kind Code:
A1
Abstract:
Provided in the present disclosure are a video reading method and apparatus, and an electronic device and a storage medium, which are applied to the technical field of three-dimensional display. The method comprises: when at least two video streams are played simultaneously, acquiring a cache block number of a video to be played, wherein the at least two video streams respectively correspond to at least two buffer areas, cache blocks in the at least two buffer areas are in one-to-one correspondence, and the cache blocks, which correspond to each other, in the at least two buffer areas have the same cache block number; querying a cache block address list for a cache block address of each video stream that corresponds to the cache block number; and in the buffer area corresponding to each video stream, reading a video frame from a cache block that is indicated by each cache block address, and outputting the video frame, wherein video frames stored in cache blocks corresponding to a single cache block number have the same timing. In this way, when at least two video streams are synchronously processed, a large amount of calculations can be avoided, such that the processing complexity is reduced, and the synchronous processing process is simplified, thereby improving the real-time performance and the alignment precision of video synchronization.
