Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of 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 apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a method for configuring a video output port according to an embodiment of the present application.
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 embodiment can be applied to a network video recorder, which is also called a network video recorder, and 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 for display through the video output port. In the process of outputting video data to a display by utilizing video output ports, a worker can configure a preview strategy of each video output port on an operation interface of a network video recorder through a mouse, wherein the preview strategy can comprise a preview mode of videos (such as the number of monitoring videos displayed in the display at the same time), the resolution of the monitoring videos during preview, the number of video frames and the like.
The operation interface of the network video recorder can comprise a user interface for previewing strategies, and can also comprise mouse images for selecting, applying, canceling and the like on the previewing strategies, and a user can control the mouse to enable the mouse images in the display to configure the previewing strategies of any video output port in the user interface. Because the operation interface of the network video recorder cannot be displayed in a plurality of heterogeneous video output ports at the same time, 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 a target output port. In this embodiment, the video output port where the operation interface is located may be determined by reading the operation parameters of the network video recorder, or the image recognition operation may be performed on the current screen shots of all the video output ports so as to determine the video output port where the operation parameter determination operation interface is located.
S102: determining a video output port to be configured in the network video recorder;
the video output port to be configured is a video output port which is required to be subjected to preview policy configuration at present, and an operation of receiving output port configuration information can be performed before the step, wherein the output port configuration information comprises output port identifiers of the video output ports to be configured, and the video output ports to be configured in the network video recorder can be determined according to the output port identifiers 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 is stored in a configuration file.
The number of the video output ports to be configured is not limited in this embodiment, and when there are more than two video output ports to be configured, the operation of S103 may be performed multiple times until all the preview policies of the video output ports to be configured are configured.
S103: and switching the operation interface to the video output port to be configured for output, setting the target output port as a homologous output port of the video output port to be configured, and configuring the preview strategy of the video output port to be configured through the target output port.
The method comprises the following two substeps: the substep (1) switches the video output port of the operation interface; and (3) setting the target output port as a homologous output port of the video output port to be configured in the substep (2). The present embodiment is not limited to the execution sequence of the above two sub-steps, and the present embodiment may execute the sub-step (1) first and then execute the sub-step (2), may execute the sub-step (2) first and then execute the sub-step (1), and may also execute the sub-step (1) and the sub-step (2) simultaneously.
It can be understood that, before the target output port and the video output port to be configured are not set as homologous output ports, if the operation interface is switched to the video output port to be configured for output, the operation interface is not included in the picture output by the target output port, and the operation interface is included in the picture output by the video output port to be configured. 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 to be homologous output ports, 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, outputting the same picture comprising the operation interface (namely, the picture of the picture source corresponding to the video output port to be configured) by the target output port and the video output port to be configured.
At this time, the staff 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.
And on the premise that a plurality of video outlets to be configured exist, after the preview strategies of the current video outlets to be configured are configured, the operation step of S103 is executed on other video outlets to be configured one by one until the preview strategies of all the video outlets to be configured are configured.
In this embodiment, the video output port where the operation interface is located is set as the target output port, and since the operation interface of the network video recorder is only displayed on the display corresponding to one video output port, after determining the video output port to be configured of the network video recorder, the operation interface and the mouse image are switched to the video output port to be configured for output, and the target output port is set as the homologous output port of the video output port to be configured. When the target output port is set as a homologous output port of the video output port to be configured, the content displayed in the display corresponding to the target output port can be 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 without the need of a worker to go to the position of the display corresponding to the video output port to be configured for observation. According to the embodiment, the target output port is temporarily set to be the homologous output port of the video output port to be configured, so that remote viewing of other output port preview strategies and interactive interfaces is realized, the effect of rapid operation is achieved, and the efficiency of configuring the video output port preview strategies can be improved.
As a further introduction to the corresponding embodiment of 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 be initialized, and then the video output ports may be set as the homologous output port or the heterologous output port according to the output port configuration parameters. The picture sources of the video outlets which are the same as each other and the picture sources of the video outlets which are different from each other.
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, the 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, setting the target output port as a heterogeneous output port of the video output port to be configured, and outputting a picture corresponding to a 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 of multiple video outlets according to an embodiment of the present application, where the embodiment is further described in S103 of the embodiment of fig. 1 by the video outlets to be configured when the number of video outlets to be configured is greater than 1, the embodiment may be combined with the embodiment of fig. 1 to obtain a further implementation, and the embodiment may include the following steps:
s201: determining the strategy configuration sequence of all video output ports to be configured;
the policy configuration sequence of all the video outlets to be configured can 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 embodiment can determine the picture weight of the video output port to be configured according to the type of the picture source. For example, the types of the picture sources may be divided according to the monitoring areas corresponding to the picture sources, and a higher picture weight may be set for the picture sources in the indoor area and a lower picture weight may be set for the outdoor area. 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;
the i-th video output port to be configured can 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 video output ports to be configured, i=1 when S202 is executed for the first time, i is added with 1 each time when S202 is repeated in the following step in this embodiment, i.e. i is equal to the number of times of entering S202 in this embodiment.
As a possible implementation manner, after selecting the video output port to be currently configured according to the policy configuration sequence in S202, it may also be determined whether there is a video output port that is homologous to the video output port to be currently configured and has been configured with a preview policy; 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 video output port to be configured currently for output in S203.
S203: switching the operation interface to the current video output port to be configured for output, and setting the target output port as a homologous output port of the current video output port to be configured so as to configure the preview strategy of the current video output port to be configured through the target output port;
s204: judging whether all the preview strategies of the video output ports to be configured are configured completely; if yes, go to S205; if not, entering S202;
s205: and judging that all the preview strategies of the video output ports to be configured are configured.
By the method, all video outlets to be configured can be configured one by one according to the strategy configuration sequence, and the flexibility of configuring the preview strategy can be improved.
