Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for configuring a video outlet according to an embodiment of the present disclosure.
The specific steps may include:
s101: setting a video output port where an operation interface of the network video recorder is positioned as a target output port;
the network video recorder can comprise a plurality of video output ports, and each video output port can be connected with a corresponding display, so that the network video recorder can transmit specific video data to the corresponding display through the video output port to display the specific video data. In the process of outputting video data to a display by using a video output port, a worker can configure a preview strategy of each video output port on an operation interface of the network video recorder through a mouse, wherein the preview strategy can comprise a video preview mode (for example, the number of monitoring videos simultaneously displayed in the display), the resolution of the monitoring videos during previewing, the number of video frames and the like.
The operation interface of the network video recorder can comprise a user interface used for previewing the strategy and can also comprise a mouse image used for performing operations such as selection, application, cancellation and the like on the previewing strategy, and a user can control the mouse to enable the mouse image in the display to configure the previewing strategy of any video output port in the user interface. Because the operation interface of the network video recorder cannot be simultaneously displayed in a plurality of heterogeneous video output ports, the embodiment determines the video output port where the operation interface of the network video recorder is located, and sets the video output port as the target output port. The embodiment can determine the video output port where the operation interface is located by reading the operation parameters of the network video recorder, and can also perform image recognition operation on the current screen shots of all the video output ports so as to determine the operation parameters to determine the video output port where the operation interface is located.
S102: determining a video output port to be configured in the network video recorder;
the method comprises the steps that a video output port to be configured is a video output port which needs to be configured with a preview strategy currently, operation of receiving output port configuration information can also exist before the step, the output port configuration information comprises an output port identification of the video output port to be configured, and the video output port to be configured in the network video recorder can be determined according to the output port identification obtained through analysis. In this embodiment, a unique corresponding output port identifier may be set for each video output port, and the corresponding relationship between the video output port and the output port identifier may be stored in the configuration file.
In this embodiment, the number of the video outlets to be configured is not limited, and when there are more than two outlets to be configured, the operation of S103 may be executed for multiple times until all the preview policies of the video outlets to be configured are configured.
S103: and switching the operation interface to the video output port to be configured for output, and setting the target output port as a homologous output port of the video output port to be configured, so as to configure the preview strategy of the video output port to be configured through the target output port.
Wherein, this step can include the following two substeps: the substep (1) switches the video output port of the operation interface; and (2) setting the target output port as a source output port of the video output port to be configured. In this embodiment, the execution order of the above two substeps is not limited, and the substep (1) may be executed first and then the substep (2) may be executed first, or the substep (2) may be executed first and then the substep (1) may be executed, or the substep (1) and the substep (2) may be executed simultaneously.
It can be understood that the target output port and the video output port to be configured both have their corresponding image sources, and before the target output port and the video output port to be configured are not set as the same source output ports, if the operation interface is switched to the video output port to be configured for output, the image output by the target output port does not include the operation interface, and the image output by the video output port to be configured includes the operation interface. Further, before the operation interface is not switched to the video output port to be configured for output, if the target output port and the video output port to be configured are set as the same source output port, the picture output by the target output port is the picture of the picture source corresponding to the video output port to be configured, and no operation interface exists in the output pictures of the target output port and the video output port to be configured. And after the operation interface is switched to the video output port to be configured for output and the target output port is set as a homologous output port of the video output port to be configured, the target output port and the video output port to be configured output the same picture including the operation interface (namely, the picture of the picture source corresponding to the video output port to be configured).
At this time, the worker can observe the output picture of the video output port to be configured on the display corresponding to the target output port and configure the preview strategy of the video output port to be configured, and does not need to go to the display where the video output port to be configured is located to observe the output picture.
Under the premise that a plurality of video output ports to be configured exist, after the preview strategy of the current video output port to be configured is configured, the operation step of S103 is executed on other video output ports to be configured one by one until the preview strategies of all the video output ports to be configured are configured completely.
In this embodiment, a video output port where the operation interface is located is set as a target output port, and since the operation interface of the network video recorder is only displayed on a display corresponding to one video output port, after the video output port to be configured of the network video recorder is determined, the operation interface and the mouse image are switched to the video output port to be configured to be output, and the target output port is set as a homologous output port of the video output port to be configured. When the target output port is set as the homologous output port of the video output port to be configured, the content displayed in the display corresponding to the target output port is the picture corresponding to the video output port to be configured, so that the preview strategy of the video output port to be configured can be configured through the target output port, and a worker does not need to go to the position where the display corresponding to the video output port to be configured is located for observation. According to the embodiment, the target output port is temporarily set to be the same source output port as the video output port to be configured, so that the remote viewing of other output port preview strategies and interactive interfaces is realized, the effect of quick operation is achieved, and the efficiency of configuring the video output port preview strategies can be improved.
As a further introduction to the embodiment corresponding to fig. 1, before setting the video output port where the operation interface of the network video recorder is located as the target output port, all the video output ports may also be initialized, and then the video output ports are set as the same source output port or different source output ports according to the output port configuration parameters. The image sources of the video output ports of the same source output port are the same, and the image sources of the video output ports of different source output ports are different.
As a further introduction to the corresponding embodiment of fig. 1, before the operation interface is switched to the video output port to be configured for output, a preview policy of the target output port may also be configured in the operation interface. And if all the preview strategies of the video output ports to be configured are configured completely, setting the target output port as a different source output port of the video output ports to be configured, and outputting the picture corresponding to the target picture source through the target output port.
Referring to fig. 2, fig. 2 is a flowchart of a method for configuring a preview policy for multiple video outlets according to an embodiment of the present disclosure, where in this embodiment, when the number of video outlets to be configured is greater than 1, a video outlet to be configured is further described in S103 in the embodiment corresponding to fig. 1, and a further implementation manner may be obtained by combining this embodiment with the embodiment corresponding to fig. 1, where the embodiment may include the following steps:
s201: determining the strategy configuration sequence of all video output ports to be configured;
in this step, the policy configuration sequence of all the video outlets to be configured may be determined according to the picture weight of each video outlet to be configured. The picture weight is determined according to the type of the picture source corresponding to the video output port to be configured, and the picture weight of the video output port to be configured can be determined according to the type of the picture source in the embodiment. For example, the types of the picture sources may be divided according to the monitoring regions corresponding to the picture sources, and a higher picture weight may be set for the picture sources of the indoor region and a lower picture weight may be set for the outdoor region. By the method, the preview strategy can be preferentially configured for the video output port of the indoor area picture, and the flexibility of configuring the preview strategy is improved.
S202: selecting a current video output port to be configured according to the strategy configuration sequence;
in this step, the ith video output port to be configured may be selected as the current video output port to be configured according to the policy configuration sequence, i is greater than or equal to 1 and less than or equal to N, N is the total number of the video output ports to be configured, i is equal to 1 when S202 is executed for the first time, in this embodiment, the value of i is added with 1 when S202 is repeated each time subsequently, that is, the value of i is equal to the number of times of entering S202 in this embodiment.
As a feasible implementation manner, after the current video output port to be configured is selected according to the policy configuration sequence in S202, it may be further determined whether a video output port that is homologous to the current video output port to be configured and has been configured with the preview policy exists; if yes, executing the operation of selecting the current video output port to be configured according to the strategy configuration sequence in S202; if not, continuing to execute the operation of switching the operation interface to the current video output port to be configured for outputting in the step S203.
S203: switching the operation interface to a current video output port to be configured for output, and setting a target output port as a same-source output port of the current video output port to be configured, so as to configure a preview strategy of the current video output port to be configured through the target output port;
s204: judging whether all the preview strategies of all the video output ports to be configured are configured completely; if yes, go to S205; if not, the step S202 is entered;
s205: and judging that the preview strategies of all the video output ports to be configured are completely configured.
Through the method, all the video output ports to be configured can be configured one by one according to the policy configuration sequence, so that the flexibility of configuring the preview policy can be improved.

The embodiment can set the preview strategy of the second video output port through the first video output port, and simultaneously can directly observe the display effect of the second video output port on the display corresponding to the first video output port.
After the preview strategy setting of the second video output port is completed, the operation interface and the mouse image can be switched to the third video output port for output, and the first video output port is set to be the video output port which is the same as the third video output port, so that the third video output port is set. As shown in fig. 5, fig. 5 is a schematic diagram of a display result of each video outlet when the preview policy of the third video outlet is set according to the embodiment of the present application. In this embodiment, a preview policy of the third video output port may be set through the first video output port, and meanwhile, a display effect of the third video output port may also be directly observed on a display corresponding to the first video output port.
