Problems solved by technology
[0009] In the process of video data playback or rewinding, the video segment where the event is located may only be momentary, but it is always necessary to search the data of each frame of image through the timestamp to find the corresponding I frame. Therefore, this method is time-consuming. When When the video data is large, the efficiency is low, and the video image obtained by difference calculation will be distorted

The embodiment of the invention provides a video play method and device. According to the method, a video play request is received, and the storage position of a GOP packet corresponding to a target timestamp is searched in a database according to the target timestamp in the received video play request, wherein the timestamp of each GOP packet and the storage position of each GOP packet in electronic equipment are stored in the database; and the GOP packet corresponding to the target timestamp is acquired from the electronic equipment according to the searched storage position, and the acquired GOP packet is transmitted to a player to be played. The timestamp of each GOP packet and the storage position of each GOP packet in the electronic equipment are stored in the database so that the storage position of the corresponding GOP packet can be searched according to the target timestamp after the target timestamp is received, the inquiring efficiency of the GOP packet can be enhanced and then the video play efficiency can be enhanced. Besides, complete video image information is stored in each GOP packet so that the subsequent video play authenticity can be guaranteed.
Description
technical field [0001] The present invention relates to the technical field of video playing, in particular to a video playing method and device. Background technique [0002] Video data is usually stored in the form of I frame, P frame and B frame, where the I frame records the complete video image, and the P frame and B frame record the image change relative to the video image of the I frame. At present, the process of performing video playback on saved video data usually includes the following steps: [0003] 1. Receive video playback request; [0004] 2. According to the timestamp in the video playback request, find the I frame corresponding to the timestamp in the saved video data; [0005] 3. Determine the next I frame adjacent to the I frame; [0006] 4. Obtain the difference between two I frames in the video data, determine the image of the P frame and / or B frame between the two I frames and play it. [0007] In practical applications, such as security monitoring...
