Problems solved by technology

[0005] For the video data units that have been dumped, because they only retain the key frame images in the GOP, they are not a complete GOP, so if you need to play back the video corresponding to these video data units, the video picture you watch will jump. The picture is choppy and the quality of the video picture is not good

Embodiment Construction

[0054]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0055] An exemplary embodiment of the present disclosure provides a method of storing video data, such as figure 1 As shown, the processing flow of the method may include the following steps:

[0056] Step S110 , whenever a preset video data transfer period is reached, determine a video data unit to be transferred among the pre-stored video data units.

[0057] In implementation, such...

Abstract

The disclosure relates to a method and device for storing video data, and belongs to the technical field of data storage. The method includes: whenever a preset video data transfer period is reached, determining the video data unit to be transferred among the pre-stored video data units; for at least one image sequence GOP included in each transferred video data unit , performing dump processing on the key frame image and a preset number of non-key frame images in each GOP respectively; and deleting the dumped video data unit. With the present disclosure, when the video playback operation is performed based on the key frame images and the preset number of non-key frame images in each GOP, the viewed video images are more coherent and the quality of the video images is better.

Description

technical field [0001] The present disclosure relates to the technical field of data storage, in particular to a method and device for storing video data. Background technique [0002] In the field of video surveillance, due to the limited storage space of the storage system for storing the captured video data, not all the captured video data will be stored, only the video data captured within a preset time period will be stored. For example, you can set to store video data taken within 30 days. If the current date is 2018.9.4, only video data taken between 2018.8.5 and 2018.9.4 will be stored, and video data taken before 2018.8.5 will be stored. been deleted. [0003] If the storage duration of the video data is to be extended without increasing the storage space of the storage system, the stored video data can be compressed and dumped. Compression dump processing includes compressing video data, dumping the compressed video data to another storage area in the storage sys...
