Problems solved by technology
[0004] Assume that due to some reasons, the execution node failed to store the video data of 2017.12.13. At this time, the execution node cannot upload 2017.12.13 to the management node, but the storage task is still in progress, even though the video data corresponding to 2017.12.14 has been uploaded. Successfully stored, the management node cannot know the situation
When the execution node fails, the management node switches the storage task of the failed execution node to a new execution node. The new execution node can only know that the video data before 2017.12.12 has been successfully stored, but cannot know the video data after 2017.12.12 Whether the storage is successful, at this time, in order to ensure the integrity of the video data, the new execution node needs to store all the video data after 2017.12.12, which will result in a large amount of duplicate video data being stored during storage

Embodiments of the present invention provide a video data processing method, device, system, and electronic equipment. In the method, a storage task for acquiring video data collected by a video acquisition device is received from a management node, and the task is acquired and stored in the video acquisition device. , the acquisition date is the video data of the date included in the storage task, and the storage result for each date is sent to the management node, so that when the management node detects the failure of the first execution node, it will send the storage result for each date to Send to the second execution node that is not faulty, and instruct the second execution node to obtain and store the video data that is not completely stored by the first execution node. In the present invention, what the first execution node sends to the management node is the storage result for each date, so that when the first execution node fails, the management node can instruct the unfailed second execution node to obtain and store the incomplete The stored video data avoids storing a large amount of repeated video data.
Description
technical field [0001] The present invention relates to the technical field of video data processing, in particular to a video data processing method, device, system and electronic equipment. Background technique [0002] The video cloud storage system includes a management node and an execution node. The video cloud storage system is connected with a video acquisition device, and the management node is used to manage the execution node. [0003] Generally, the management node sends a storage task to the execution node, so that the execution node obtains and stores video data from the video collection device. After the execution node successfully executes a storage task, it will report the date corresponding to the successfully stored video data. For example, if the execution node successfully stores the video data of 2017.12.12, it will report 2017.12.12 to the management node. When the date is reached, it is known that the video data corresponding to the date has been suc...
