At present, VR panoramic video generally adopts an ERP (equal distance cylindrical projection, abbreviated as ERP) projection mode to project each frame of picture as a rectangular picture.
The VR panoramic video playing process specifically comprises the following steps: the VR streaming media server sends the VR panoramic video to a user side (VR helmet and glasses, wherein sensors, processors, storage, screens and the like are integrated in the VR panoramic video, and the VR panoramic video is connected with the VR server in a wired or wireless network streaming mode to realize data transmission); the user side downloads the video file through a corresponding streaming media protocol; the method comprises the steps that a user side analyzes and decodes a video file through an internal program and a processor, and after each frame of rectangular video picture is obtained, the corresponding rectangular picture is rendered into a spherical picture according to an ERP mode; then determining an area which can be watched by a user in the spherical picture according to the watching direction of the eyes of the user, and acquiring the picture of the area from the spherical picture; and finally, performing barrel-shaped anti-distortion (a distortion phenomenon which does not influence imaging definition) processing on the acquired picture, and rendering the processed picture to a user side display screen for picture display.
The invention mainly aims to solve the technical problems that in the prior art, pictures are blocked and unsmooth in the playing process of a large-size VR panoramic video, discomfort experience of dizziness is easily caused, and safety in the transmission process of the VR panoramic video is high.
The following description will be made for the principles of the related art used in the embodiments of the present invention:
the traditional video on demand can be played only by loading the whole video source file, so that the user experience is influenced and the video resource is leaked under the condition that the network access rate of a common user is low. The streaming transmission technology is that a video source file is divided into video compression packets through special processing, a streaming media server continuously transmits data to a user client in real time, the client uses a corresponding player to gradually unpack, decode and render the file packets, and finally outputs and plays the file packets, and the subsequent compression packets are continuously downloaded in real time, so that the effect of continuously playing videos is achieved.
The HLS (HTTP Live Streaming, HTTP-based adaptive bitrate Streaming media transport Protocol, HLS for short) is a mature and excellent video Streaming network transport Protocol developed by Apple (Apple) based on HTTP (hypertext Transfer Protocol, HTTP for short). The iOS and the android system also support the HLS protocol originally, and dynamic self-adaptive code rate playing can be realized at various user terminals without secondary development.
In order to realize the HLS streaming media protocol, the invention adopts FFmpeg (fast forwarded Mpeg) technology to split a video original file into a plurality of small slice files (ts files), and simultaneously generates an index file (. m3u 8), wherein the index file is similar to a dictionary directory and is stored in the related information of the video related slice files.
Google VR SDK For Android is a complete set of VR video viewing underlying software development kit released by Google corporation, wherein two support modes are determined with respect to video playing: video playing of the local video stream and video playing based on the HLS streaming media protocol. Based on the kit, an HLS streaming media panoramic player can be developed.
Video stream playing address and video file security: generally, a video stream playing address (URL, Uniform Resource Locator) is subjected to anti-theft processing, and a common method is a timestamp anti-theft chain; in the HLS streaming media protocol, a video file needs to be downloaded progressively at a client, and then the video file is analyzed, decoded and rendered to achieve a playing effect, so that a certain file leakage risk exists in the process.
The invention uses the symmetric encryption algorithm to encrypt the video file first, and mixes the decryption algorithm in the video player program, so that the video can be played only through the appointed player, and the video security is further ensured.
