This application discloses a panoramic playback method, the method comprising: receiving a video file sent by a server, the video file including panoramic video data and at least one second-view data, wherein the second-view data refers to the video data of the panoramic video data in a second-view perspective; and when second-view playback is selected, playing the panoramic video data in a second-view perspective based on the second-view data. This application also discloses a client and a server.

This invention discloses an end-to-end verification method, system, and product for video streams based on Schnorr signatures. The sending end first encodes the audio and video streams into a continuous sequence. For each encoded transmission packet, a point in the group is calculated using random numbers as the random commitment point for the frame signature, where is the generator of the selected elliptic curve group, and the group order is a prime number. Then, a signature scalar is calculated according to the Schnorr signature algorithm. Next, the original video frame data, the random point, and the signature scalar are combined into an authentication data packet, which is pushed to the server and client in real time via a network protocol. Finally, the client performs instant authentication and cache management, while the server performs frame-by-frame verification and aggregated storage. This invention utilizes the linear aggregation characteristics of Schnorr signatures to achieve efficient authentication and traceability of real-time video streams and historical stored data while significantly reducing storage space requirements, ensuring the integrity and evidentiary value of the video data.

The embodiment of the invention discloses a video stream coding configuration method, system and device and a storage medium. According to the technical scheme provided by the embodiment of the invention, the source stream frame rate of the video source stream is determined, a plurality of set frame rate interval ranges are compared based on the source stream frame rate, the frame rate interval ranges correspond to different coding parameter settings, and the coding parameters comprise coding delay parameters; determining a corresponding coding parameter as a final coding parameter according to the frame rate interval range in which the source stream frame rate falls; and configuring encoding parameters of an encoder of the video source stream based on the final encoding parameters to encode the video source stream based on the final encoding parameters. By adopting the technical means, the introduced coding delay is reduced by adjusting the coding delay parameter, the problem of video playing lagging is avoided, and the watching fluency experience of audiences is further improved.
