Detailed Description
In the prior art, the original video data of the equipment is usually acquired during live preview and video playback, and the video resources are frequently forwarded and played, so that the risk of leakage of a confidential sensitive video is increased, and the leakage source is difficult to track. A Digital Watermark (Digital Watermark) is a mark that is embedded covertly in a noise-tolerant signal, such as audio, video or image data. Digital watermarks can be used to verify the authenticity or integrity of a carrier signal and to reveal the identity of its owner. Therefore, watermark information of forwarded classified sensitive videos, such as equipment, users and the like, is embedded in the video monitoring system, so that video point positions and leakage sources can be quickly and accurately positioned when the videos leak, and defects in video management work can be found in time.
The main process of video watermarking comprises the following steps: receiving a video stream, decoding, watermarking, encoding, and transmitting the watermarked video stream. The video coding and decoding consumes very large resources, and the performance consumption of the CPU for carrying out the video soft coding and decoding is about forty times of that of the video forwarding. Therefore, if the two flows of video forwarding and video watermarking are combined, the service stability is greatly influenced, the software specification is not well determined, and the system resources are wasted.
In order to improve the encoding and decoding efficiency without affecting the normal Video forwarding, the watermark streaming media and the forwarding streaming media need to be separated, on one hand, a special Video encoding and decoding chip (Video Processing Unit) is conveniently deployed in the watermark streaming media, the watermarking speed is improved, meanwhile, the coupling degree of the watermark and the forwarding flow can be reduced, and the system can conveniently perform function cutting, capacity expansion and capacity reduction.
However, decoupling brings a new problem: when the watermark state is switched, how to make the stream media services of live preview, video playback, etc. to have no perception. After decoupling, the watermark streaming media and the forwarding streaming media operate independently, and the streaming source address changes before and after the watermark state switching. For example, when the watermark state is changed to on, the source address is changed from the forwarding streaming media to the watermark streaming media. When the watermark state is switched, the video stream of the relevant point position is disconnected, the concealment is poor, the safety is insufficient, and the user experience needs to be improved.
In order to improve at least one of the above technical problems proposed by the present application, embodiments of the present application provide a data processing method and apparatus, a server, and a storage medium, and the following describes technical solutions of the present application through possible implementation manners.

It should be understood that, in other embodiments, the order of some steps in the data processing method of this embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted. The flow of the data processing method shown in fig. 2 is described in detail below.
Step S210, in response to the watermark state enabling signal, obtains the monitoring data sent by the monitoring device 200 by forwarding the streaming media and forwards the monitoring data to the watermark streaming media.
In detail, after the watermark state is turned on, the monitoring data can be obtained by forwarding the streaming media and sent to the watermark streaming media.
Step S220, perform watermarking on the monitoring data through the watermark streaming media to obtain watermark monitoring data and send the watermark monitoring data to the forwarding streaming media.

Step S230, sending the watermark monitoring data to the terminal device 300 by forwarding the streaming media.
In detail, after the watermark monitoring data is acquired through step S220, the watermark monitoring data may be transmitted to the terminal device 300 for processing by forwarding the streaming media.
According to the method, in the open state of the watermark state, the watermark stream media obtains the monitoring data sent by the forwarding stream media to perform watermark processing to obtain the watermark monitoring data, and the watermark monitoring data is sent to the forwarding stream media so that the forwarding stream media sends the watermark monitoring data to the terminal equipment, so that the data is sent to the terminal equipment through the forwarding stream media when the watermark state is open, and the problems of poor concealment, insufficient safety and low user experience of video forwarding caused by disconnection of video streams of related point positions when the watermark state is switched in the prior art are solved.

The point location corresponding signal that the user clicks on the client interface of the terminal device 300 to add the monitoring device 200 may be obtained, and the live request of the monitoring device 200 is sent to the streaming media scheduling service, so that the server 100 establishes connections with the monitoring device 200 and the terminal device 300, respectively.
Before step S210, when the watermark status is off, the data processing method may further include the step of acquiring monitoring data by forwarding the streaming media and sending the monitoring data to the terminal device 300.

Step S242, acquiring the monitoring data sent by the monitoring device 200 through the target forwarding streaming media.
It should be noted that, in order not to affect the forwarding of the monitoring data and the forwarding of the watermark monitoring data, the specific steps of sending the monitoring data in step S250 and sending the watermark monitoring data in step S230 are not limited, and may be set according to the actual application requirements. For example, in an alternative example, step S250 may include the step of transmitting the monitoring data through a first channel, and step S230 may include the step of transmitting the watermark monitoring data through a second channel. Therefore, on the basis of fig. 2 and fig. 3, fig. 5 is a schematic flowchart of another data processing method provided in the embodiment of the present application, and referring to fig. 5, step S250 may include:
step S251, a first channel is set by forwarding the streaming media, and the monitoring data is forwarded to the terminal device 300 through the first channel.

Step S230 may include:
step S231 sets a second channel by forwarding the streaming media, and forwards the watermark monitoring data to the terminal device 300 through the second channel.
In detail, after the streaming media scheduling service receives the watermark state change message, a request for creating a new forwarding channel may be sent to forward the streaming media, and the client of the terminal device 300 may be transferred from the forwarding channel of step S240 to the newly created forwarding channel.
According to the method, the watermark channel is created in the watermark streaming media and the new forwarding channel is created in the forwarding streaming media, the watermark channel acquires the video stream from the original forwarding channel, the video stream is watermarked and then sent to the new forwarding channel, the client side of the terminal device 300 is transferred to the new forwarding channel, the video stream of the client side is not disconnected when the watermark state is switched, the video is acquired from the same forwarding streaming media, the IP and the port are not changed, the non-perception switching can be realized, and the concealment, the safety and the user experience are improved.
For step S210, it should be noted that the specific opening mode of the watermark state is not limited, and may be set according to the actual application requirement. For example, in an alternative example, the point watermark status of the monitoring device 200 may be modified to an on state via a Web page.
As for step S220, it should be noted that the specific steps for obtaining the watermark monitoring data are not limited, and may be set according to the actual application requirements. For example, in an alternative example, when the number of the watermark streaming media is plural, step S220 may include a step of selecting a target watermark streaming media from the plural watermark streaming media. Therefore, on the basis of fig. 2, fig. 6 is a schematic flowchart of another data processing method provided in the embodiment of the present application, and referring to fig. 6, step S220 may include:
step S221, obtaining load information of the multiple watermark streaming media, and selecting a target watermark streaming media from the multiple watermark streaming media according to the load information.
In detail, the streaming media scheduling service may select the least loaded watermark streaming media as the target watermark streaming media through a load balancing policy.
Step S222, performing watermark processing on the monitoring data through the target watermark streaming media to obtain watermark monitoring data, and sending the watermark monitoring data to the forwarding streaming media.
In detail, the streaming media scheduling service may send a request for creating a watermark channel to a target watermark streaming media, where the watermark channel obtains monitoring data through a forwarding channel (a first channel) in the forwarding streaming media, and sends the monitoring data to a new forwarding channel (a second channel) in the forwarding streaming media after performing watermark processing.
As for step S220, it should be noted that the specific steps for performing the watermarking process are not limited, and may be set according to the actual application requirements. For example, in an alternative example, step S220 may include a step of performing watermarking from customer information. Therefore, on the basis of fig. 2, fig. 7 is a schematic flowchart of another data processing method provided in the embodiment of the present application, and referring to fig. 7, step S220 may include:
step S223, obtaining the client information sent by the forwarding streaming media.
In detail, when the client of the terminal device 300 obtains the monitoring data by forwarding the streaming media, the client information (which may include, for example, a login user name, an IP, requested device information, and the like) is bound to the egress side of the forwarding channel (the first channel) at the same time, so as to obtain the client information.
Step S224, the monitoring data is watermarked by the watermark stream media according to the client information, and the watermark monitoring data is obtained and sent to the forwarding stream media.
In detail, the main flow of performing the watermark processing is as follows: receiving a video stream, decoding, watermarking, encoding, and transmitting the watermarked video stream. Firstly, carrying out protocol resolution processing (a protocol layer can comprise http, rtmp, file and the like) on a video stream to obtain data with a packaging format; secondly, decapsulating the data with the encapsulated format (the encapsulated format layer may include mkv, mp4, flv, avi, etc.), so as to obtain video compressed data; then, video decoding processing is performed on the video compressed data (the pixel layer may include yuv420p, yuv422p, rgb24, etc.), resulting in video pixel data; and finally, embedding the client information as watermark content into the pixel data, and performing video coding, format packaging and protocol header adding processing to obtain watermark monitoring data.
As for step S224, it should be noted that, the specific way of performing the watermark processing according to the client information is not limited, and may be set according to the actual application requirement. For example, in an alternative example, step S224 may include the following sub-steps:
and displaying the client information in the monitoring data through the watermark streaming media to obtain watermark monitoring data and sending the watermark monitoring data to the forwarding streaming media.
That is, the client information is directly displayed in the video stream as the watermark to obtain the watermark monitoring data.
For another example, in another alternative example, the watermark monitoring data may be obtained by embedding the client information as an invisible watermark in a frame image included in the video stream by a digital watermarking algorithm.
In practical application, a video monitoring system and a storage system can be respectively deployed, a large number of front-end cameras, NVRs and other devices are accessed, and platform video plans of part of the devices are configured. In view of the huge influence of the confidential sensitive video leakage event on the society, the video monitoring system can be upgraded to a video tracing system supporting the watermark, the watermark is configured for the video of the monitoring equipment 200 in the sensitive area, and the quick positioning of the leakage source is realized.
Because the watermark stream media and the forwarding stream media are arranged in a decoupling mode, the video plan of the equipment cannot be disconnected in the process of upgrading the system. After the upgrade is completed, the Web page of the server 100 is logged in, and the point location watermark of the sensitive monitoring device 200 is configured. At this time, the storage system still obtains the original video of the monitoring device 200 from the original forwarding channel for forwarding the streaming media, and the client live preview of the terminal device 300 is switched to the newly-created forwarding channel on the same forwarding streaming media for forwarding the watermarked video. Since the live is still taken from the same forwarded streaming media, IP and port are unchanged and an agnostic handover can be achieved.
