It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a video data processing method according to an exemplary embodiment, and as shown in fig. 1, the video data processing method may be applied to a server that may provide a service for video data, for example, as a home platform of video data, or provide service support for the home platform of video data, the server may communicate with one or more terminals, and each terminal may upload video data to the server. In one embodiment, the home platform of the video data may be understood as a storage platform, a distribution platform, and the like of the video data.
The processing method of video data shown in fig. 1 may specifically include the following steps.
In step S11, the video data, and the video statistical information of the video data and/or the account statistical information of the home account of the video data are acquired.
In the embodiment of the disclosure, video statistical information of video data and video data is acquired, or account statistical information of a home account of the video data and the video data is acquired, or the video statistical information of the video data and the account statistical information of the home account of the video data are acquired. The home account of the video data may be an author, an uploader, a sharer, a publisher, and the like of the video data. The video data may be any video data stored in the server, or the video data may be video data satisfying a preset condition. Wherein, the preset conditions may include but are not limited to: originating from a terminal in communication with the server. The server may store the video data uploaded by the terminal locally in the server, or store the video data uploaded by the terminal in the storage server.
In the embodiment of the disclosure, the server not only stores the video data, but also records the video statistical information of each video data and/or the account statistical information of the home account of each video data. The server can establish a corresponding relationship between the statistical information of the video data acquired in real time and the identification information of the video data, wherein the statistical information of the video data at least comprises the video statistical information and account statistical information of the home account of the video data. Therefore, after the server acquires the video data, the server may acquire the video statistical information and/or the account statistical information corresponding to the identification information, that is, the video statistical information and/or the account statistical information of the video data, according to the corresponding relationship between the identification information of the video data and the video statistical information and/or the account statistical information acquired in real time. The correspondence may vary with real-time changes in the video statistics and/or account statistics. The video statistics information may indicate popularity of the video data, and the account statistics information may indicate popularity of the home account.
In step S12, when the video statistics information and/or the account statistics information satisfy a preset adding condition, adding watermark information to the video data.
In the embodiment of the disclosure, after the video statistical information and/or the account statistical information are obtained, whether the video statistical information and/or the account statistical information meet the preset adding condition may be determined. Adding watermark information to the video data when the video statistical information and/or the account statistical information meet the adding condition; and when the video statistical information and/or the account statistical information do not meet the adding condition, not adding the watermark information to the video data. The watermark information may be associated with a home account and/or a home platform. For example, the watermark information is an account name, an account number, and the like of the home account, and the watermark information may also be a name, a trademark, and the like of the home platform.
In embodiments of the present disclosure, in addition to adding watermark information to video data, the video data may be beautified, encoded, decoded, compressed, converted, and so on.
According to the video data processing scheme provided by the embodiment of the disclosure, video data and video statistical information of the video data and/or account statistical information of a home account of the video data are obtained, wherein the video statistical information represents the popularity of the video data, and the account statistical information represents the popularity of the home account. And then, judging whether the video statistical information and/or the account statistical information meet the preset adding condition, and adding watermark information to the video data when the video statistical information and/or the account statistical information meet the preset adding condition, wherein the watermark information can be associated with the attribution account of the video data and/or the attribution platform of the video data.
According to the embodiment of the disclosure, before adding the watermark information to the video data, whether the video statistical information of the video data and/or the account statistical information of the home account of the video data meet the preset adding condition is judged, and when the video statistical information and/or the account statistical information meet the preset adding condition, the watermark information is added to the video data; and when the video statistical information and/or the account statistical information do not meet the preset adding condition, not adding the watermark information to the video data. The embodiment of the disclosure can add the watermark information to the video data of which the video statistical information and/or the account statistical information meet the preset adding condition, but not to add the watermark information to each video data, thereby reducing the number of adding the watermark information to the video data and reducing the computing resource consumption of the attribution platform. Moreover, the number of the video data added with the watermark information is reduced, the storage space occupied by the video data added with the watermark information is correspondingly reduced, and the storage resource consumption of the attribution platform is also reduced.
In an exemplary embodiment of the present disclosure, in the execution of the above step S12, the video statistic information may be compared with a video statistic threshold, or the account statistic information may be compared with an account statistic threshold, or the video statistic information may be compared with a video statistic threshold and the account statistic information may be compared with an account statistic threshold. And when the video statistical information is greater than or equal to the video statistical threshold, the video statistical information is considered to meet the adding condition. Or, when the account statistical information is greater than or equal to the account statistical threshold, the account statistical information is considered to satisfy the adding condition. Or, when the video statistical information is greater than or equal to the video statistical threshold and the account statistical information is greater than or equal to the account statistical threshold, the video statistical information and the account statistical information are both considered to satisfy the adding condition. That is, when the video statistics information is greater than or equal to the video statistics threshold, or when the account statistics information is greater than or equal to the account statistics threshold, or when the video statistics information is greater than or equal to the video statistics threshold and the account statistics information is greater than or equal to the account statistics threshold, the watermark information is added to the video data.
In practical applications, the video statistics may include, but are not limited to: at least one of sharing times, playing times and downloading times. The account statistics may include an associated account number for the home account, and the like. Video statistics thresholds may include, but are not limited to: a sharing time threshold, a playing time threshold and a downloading time threshold. The account statistics threshold may comprise an associated account number threshold, and the like. The video data may be watermarked when at least one of the following conditions is met: the video statistical information is greater than or equal to a video statistical threshold, the sharing times are greater than or equal to a sharing times threshold, the playing times are greater than or equal to a playing times threshold, the downloading times are greater than or equal to a downloading times threshold, the account statistical information is greater than or equal to an account statistical threshold, and the number of the associated accounts is greater than or equal to an associated account number threshold.
The video data may not be watermarked when at least one of the following conditions is met: the sharing times are smaller than the sharing time threshold, the playing times are smaller than the playing time threshold, and the downloading times are smaller than the downloading time threshold.
The embodiment of the disclosure can judge whether the video data meets the adding condition from the aspect of the video data (such as video statistical information), judge whether the video data meets the adding condition from the aspect of the attribution account of the video data (such as account statistical information), or judge whether the video data meets the adding condition from the aspect of the video data itself (such as video statistical information) and the attribution account (such as account statistical information). A plurality of limiting conditions are set for adding watermark information to video data, so that the video data which can be added with the watermark information is screened out from a plurality of video data according to the limiting conditions, and the video data which do not need to be added with the watermark information is excluded.
In an exemplary embodiment of the present disclosure, in the execution of the above step S11, the video data may be acquired when it is determined that the video data is transmitted. The video data is transmitted, including but not limited to being shared or downloaded or transmitted. In practical applications, when a sharing instruction or a downloading instruction or a sending instruction for video data is received, the video data may be considered to be shared or downloaded or transmitted. For example, if an account of a certain terminal needs to share video data with other accounts of other terminals, the account sends a sharing instruction to the server through the terminal, where the sharing instruction may include identification information of the video data, a sharing operation identification, and the like. For another example, if an account of a terminal needs to download video data to a local area, the account sends a download instruction to the server through the terminal, and the download instruction may include identification information of the video data, a download operation identifier, and the like. After receiving the sharing instruction or the downloading instruction, the server may extract the identification information of the video data from the sharing instruction or the downloading instruction, and then obtain the video data according to the identification information.
In an exemplary embodiment of the present disclosure, when it is determined that video data is shared or downloaded or transmitted, it is also necessary to search whether there is video data corresponding to the video data to which watermark information is added. If there is video data to which watermark information is added, which corresponds to the video data, it is not necessary to add watermark information to the video data, and the searched video data may be used as the video data to which the watermark information is added. And if the video data which is corresponding to the video data and added with the watermark information does not exist, acquiring the video data, further judging whether the video statistical information and/or the account statistical information of the video data meet the adding condition, and adding the watermark information to the video data when the video statistical information and/or the account statistical information meet the adding condition.
According to the embodiment of the disclosure, the adding condition is set when judging whether the video data can be added with the watermark information, the precondition for adding the watermark information to the video data is limited from the aspect of application scenes (such as sharing, downloading and the like), and the safety of adding the watermark information to the video data is further enhanced.
In an exemplary embodiment of the present disclosure, during the execution of the step S12, a watermarking process of the server may be invoked to add watermarking information to the video data, and then the video data added with the watermarking information is stored to the storage device.
In an exemplary embodiment of the present disclosure, a Query Per Second (QPS) of the watermarking process, that is, a QPS of the video data to which the watermark information is added, and/or a storage limit value of the storage device may also be detected according to a preset period. At least one of the video statistics threshold and the account statistics threshold is then adjusted according to the QPS of the watermarking process and/or the storage limit of the storage device.
In practical application, a QPS comparison result can be obtained by comparing a QPS of the watermarking process in the current cycle with a QPS of the watermarking process in the previous cycle. When the QPS comparison result indicates that the QPS of the watermarking process of the current cycle is greater than the QPS of the watermarking process of the previous cycle, the value of at least one of the video statistics threshold and the account statistics threshold may be decreased. When the QPS comparison result indicates that the QPS of the watermarking process of the current cycle is smaller than the QPS of the watermarking process of the previous cycle, the value of at least one of the video statistics threshold and the account statistics threshold may be increased. Or comparing the storage limit value of the storage device of the current period with the storage limit value of the storage device of the previous period to obtain a storage limit value comparison result. The value of at least one of the video statistics threshold and the account statistics threshold may be decreased when the storage limit comparison indicates that the storage limit of the storage device of the current cycle is greater than the storage limit of the storage device of the previous cycle. The value of at least one of the video statistics threshold and the account statistics threshold may be increased when the storage limit comparison indicates that the storage limit of the storage device of the current cycle is less than the storage limit of the storage device of the previous cycle.
Or, comparing the QPS of the watermarking process of the current cycle with the QPS of the watermarking process of the previous cycle to obtain a QPS comparison result, and comparing the storage limit value of the storage device of the current cycle with the storage limit value of the storage device of the previous cycle to obtain a storage limit value comparison result. When the QPS comparison result indicates that the QPS of the watermarking process of the current cycle is greater than the QPS of the watermarking process of the previous cycle, and the storage limit value comparison result indicates that the storage limit value of the storage device of the current cycle is greater than the storage limit value of the storage device of the previous cycle, the value of at least one of the video statistics threshold and the account statistics threshold may be decreased. When the QPS comparison result indicates that the QPS of the watermarking process of the current cycle is less than the QPS of the watermarking process of the previous cycle, and the storage limit value comparison result indicates that the storage limit value of the storage device of the current cycle is less than the storage limit value of the storage device of the previous cycle, the value of at least one of the video statistics threshold and the account statistics threshold may be increased.
Embodiments of the present disclosure may dynamically adjust the video statistics threshold and/or the account statistics threshold in conjunction with system resources of the server of the video data (e.g., QPS of the watermarking process, storage limits of the storage device). When the system resources are relatively sufficient, the numerical value of the video counting threshold value and/or the account counting threshold value can be properly reduced, so that the number of video data meeting the adding condition is increased, watermark information is added to more video data, and the resource utilization rate of the server is improved. When the system resources are relatively short, the value of the video statistical threshold and/or the account statistical threshold can be properly increased, so that the number of video data meeting the adding condition is reduced, watermark information is added to fewer video data, and the processing pressure of a server is relieved.
Based on the above description about an embodiment of a method for processing video data, a watermarking scheme for video data is described below. When video data is propagated from a home platform to other platforms or downloaded, watermark information is usually added to the video data, so that the copyright of an author of the video data is protected by the watermark information, or the influence of the home platform is expanded. As shown in fig. 2, the watermarking scheme for video data may involve a third party platform (including a download terminal), a home platform host process, a home platform watermarking process, and a watermarked video storage device.
When an account requests to share video data to a third-party platform or download the video data by using a terminal logging in the account, the home platform main process can search whether watermark video data corresponding to the video data exist. And if the watermark video data corresponding to the video data exist, returning the watermark video data to the terminal where the account is located. If the watermark video data corresponding to the video data does not exist, judging whether the frequency of sharing the video data to the third-party platform is greater than or equal to a sharing frequency threshold value or not, or judging whether the playing frequency of the video data is greater than or equal to a playing frequency threshold value or not, or judging whether the number of fans of an author of the video data is greater than or equal to a fan number threshold value or not. And when all judgment conditions or part of judgment conditions are met, calling a home platform watermark adding process to add watermark information to the video data to obtain watermark video data, and then storing the watermark video data to a watermark video storage device.
Moreover, the values of the sharing time threshold, the playing time threshold, the fan number threshold, and the like can be adjusted according to the change condition of the resource amount (such as QPS of the watermark adding process and the storage limit value of the storage device) of the home platform. For example, if the QPS of today's watermarking process is increased by 30% compared to the QPS of yesterday's watermarking process, and the storage limit value of today's storage device is also increased by 30% compared to yesterday's storage limit value, the values of the sharing number threshold, the playing number threshold, and the fan number threshold may be modified proportionally. The purpose of modifying the values of the sharing time threshold, the playing time threshold and the fan number threshold is to make the QPS of the watermark adding process reach 130% of yesterday, or the storage limit value of the storage device reach 130% of yesterday. It should be noted that, in the process of modifying the values of the sharing time threshold, the playing time threshold, and the fan number threshold, a smaller proportion, for example, 5%, may be reduced each time, and the values of the sharing time threshold, the playing time threshold, and the fan number threshold are modified in a manner of multiple times of small proportions, so as to finally achieve the desired effect.
