The partial terms that may be referred to in this application are explained first:
the video management system comprises: the system is also called a video cms system, and can upload, transcode, release and offline manage copyright videos of video websites.
OTT system: in recent years, various internet companies spread apps at television terminals to play copyright videos, and an OTT system is a background system for managing the copyright videos.
Redis set: set for Redis is an unordered Set of String types. The members of the set are unique, meaning that duplicate data cannot appear in the set. The aggregation in Redis is realized by a hash table, so the time complexity of adding, searching and deleting is O (1).
In the prior art, when a video management system changes video information, the video management system issues a video information change message as a message producer, and the content of the message is the latest video information. And the OTT system is used as a message consumer to receive the video information change message, and after the OTT system receives the video information change message each time, the OTT system updates the video information table of the database according to the latest video information aiming at the video information. However, when the video information table of the video management system is frequently changed, since the OTT system consumes the video information change messages in real time, each video information change message causes the OTT system to update the database once, which causes a lot of repeated updates of the same piece of video information by the OTT system in a short time, thereby causing waste of system resources.
Therefore, in order to solve the above problem, embodiments of the present application provide a video data updating method, apparatus, device, and readable storage medium, which can set a video information change table for filtering repeated information in advance, and obtain a video change message in the video information change table at a specific frequency to update video data, so as to avoid updating a large number of repeated video data according to the same video change message, reduce unnecessary data updates, and reduce the number of updates of video data and greatly reduce waste of system resources under the condition of ensuring data synchronization between an OTT system and a video management system.

In this embodiment, when video data stored in the video management system is changed, the video management system generates a video change message and sends the video change message to the OTT system, so that the OTT system receives the video change message sent by the video management system. Wherein the video change message includes a video ID of the video data to be updated. It is understood that the situation causing the change of the video data stored in the video management system may include: video release; video is downloaded; changing information such as video titles, brief introduction and cover drawings; video charging status changes, etc.
S102, storing the video change message in a video information change table, wherein the video information change table is used for filtering repeated video change messages.
In this embodiment, after receiving the video change message, the video change message may be stored in a video information change table, where the video information change table is used to filter repeated video change messages. It can be understood that there may be repeated data in the video change message sent by the video management system, and in order to avoid performing a large number of repeated video data updates according to the same video change message, the video change message may be stored in a preset video information change table, and the video information change table filters the repeated data in the video change message, so that only the non-repeated data in the video change message is left.
In one possible implementation, the video change message table may be a Redis set. Since duplicate data cannot occur in a Redis set, the Redis set may serve as a filter for duplicate data. In particular, the Redis set may be created in real-time according to the current timestamp. For example, if the current time is 15 points at 5/6/2022 at 02 points, then the redeseset key value is created as follows: vid _202205061500, namely the redeset key values created between point 15 and point 01 and point 15 and point 10 are all: vid _ 202205061500; the redisset key values created between points 15 and 11 and points 15 and 20 are all: vid _202205061510, and so on. The value in the corresponding redisset set is a list of video ids in the video change message.
S103, acquiring the filtered video change information in the video information change table every first preset time.

It is understood that the first preset time can be set according to actual requirements. Preferably, the first preset time may be 10 minutes.
In a possible implementation manner, before obtaining the filtered video change message in the video information change table, it may be determined whether the video information change table stores the video change message, if so, the video information change table is executed to obtain the filtered video change message in the video information change table every first preset time, and if not, no operation is performed.
S104, determining the video data to be updated corresponding to the filtered video change message from a video database, and updating the video data to be updated according to the filtered video change message.
In this embodiment, after the filtered video change message is obtained, the video data to be updated corresponding to the filtered video change message may be determined. Specifically, the video ID of the video data to be updated may be obtained according to the filtered video change message, and then the video data to be updated may be determined according to the video ID and the video database. It can be understood that the video ID to be updated can be extracted from the video change message, and the video database stores the video ID, the video data to be updated, and the corresponding relationship between the video ID and the video data to be updated.
In this embodiment, after the video data to be updated is determined, the video data to be updated may be updated according to the filtered video change message. Specifically, a video data update request may be sent to the video management system first, where the video data update request includes a video ID of the video data to be updated, then the video update data returned by the video management system is received, where the video update data is obtained by the video management system according to the video ID, and finally the video data to be updated in the video database is updated according to the video update data. It is understood that the video management system stores therein the video ID, the video update data, and the correspondence between the video ID and the video update data. After the video update data is obtained, the video update data can be stored in the storage position of the video data to be updated, and the video data to be updated is deleted, so that the update process of the video data to be updated is completed.
In a possible implementation manner, after the video data to be updated is updated according to the filtered video change message, the obtained filtered video change message can be deleted from the video information change table, so that the OTT system is prevented from repeatedly updating the same video change message for many times, unnecessary data updating is reduced, and waste of system resources is greatly reduced.
In a possible implementation manner, the video data stored in the video management system may be acquired every second preset time, and whether the video data in the video database is consistent with the video data stored in the video management system is determined, where the second preset time is greater than the first preset time; and if the video data in the video database is inconsistent with the video data stored in the video management system, updating the video data in the video database according to the video data stored in the video management system. Specifically, the second preset time may be set according to actual needs, and preferably, the second preset time may be one day. It can be understood that after the second preset time, the full amount of video data in the video management system may be acquired and compared with the full amount of video data in the video database in the OTT system, and when the data are inconsistent, the video data in the video database in the OTT system, which is inconsistent with the video management system, is synchronously updated with reference to the full amount of data in the video management system, so as to further ensure the synchronization between the video data in the video management system and the video data in the OTT system.
