Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Fig. 1 is a flow chart of a video playing method provided in the present application, where an execution body for executing the method of the present embodiment may be located at a server side or a client side, and the method includes the following steps:

s101: when a video stream playing request of a certain mobile scene triggered by a user from an interface is received, the video stream of the certain mobile scene is obtained, the video stream is displayed, and a next video stream is obtained, wherein the obtaining of the next video comprises reading the next video stream after the execution of a preset action is completed.

In this embodiment, a user may select different mobile scenes through the visual configuration interface, so as to play a video in the mobile scene. The moving scene may be a scene involving a target object, which may be an object such as a pedestrian, a vehicle, or the like. The video stream corresponding to the mobile scene may be a surveillance video, which may be a video collected by a high-point camera disposed in each road. Further, the moving scene is often determined according to the target object, so when the target object is monitored, the moving track of the target object can be acquired first, the moving scene related to the target object can be determined according to the moving track, and when the moving scene is determined, the moving scene can be determined according to the actual scene related to the moving process according to the moving track, such as an intersection scene, a market scene and other scenes with position points can be used as the moving scene. Each mobile scene may correspond to a plurality of monitoring devices, such as cameras, through which a monitoring video in each scene is generated. It should be appreciated that the movement trajectory may be a trajectory pre-planned for the target object.

After the video stream of the mobile scene is acquired, the video stream is displayed, and the next video stream is acquired at the time of display, before the display is finished or before the display. The next video stream may be the video stream of the next moving scene or the video stream of the next time.

Further, acquiring the next video stream may be interpreted as that after the preset action is performed, the next video may be obtained, for example, if the next video stream is obtained and there is a need to perform an operation on the next mobile scene monitoring device, such as account login, verification, etc., the action is automatically performed during the presentation. It should be understood that the design of the preset actions may be made as needed according to the actual business scenario.

S102: and if the video stream display is determined to be ended, decoding the next video stream to display the next video stream, taking the next video stream as a current video stream, and acquiring the next video stream of the current video stream.

In this embodiment, after determining that the current video stream is finished, the next video stream is decoded, so that an image of the next video stream can be displayed. In the present specification, the decoding method of the video stream is not particularly limited, and may be set according to practical applications.

When the next video stream is displayed, the currently displayed video stream can be used as the current video stream, the next video stream of the current video stream is acquired, and the process is repeated.

S103: and if the current video stream is determined to be displayed and the next video stream is not available, determining that the monitoring video is displayed.

In this embodiment, if the client determines that there is no next video stream after the current video stream is displayed, it may determine that the monitoring video is displayed.

As an optional implementation manner of this embodiment, before responding to a video stream playing request of a mobile scene triggered by a user from an interface, the method includes: acquiring a moving track of a target object, and determining a moving scene related to the target object according to the moving track; after receiving a configuration request of a user for all the sequence of the mobile scenes through the visual interface, determining a scene sequence formed by all the mobile scenes according to the sequence.

In this optional implementation manner, the moving scene is often determined according to the target object, so when the target object is monitored, the moving track of the target object can be obtained first, the moving scene related to the target object can be determined according to the moving track, and when the moving scene is determined, the moving scene can be determined according to the actual scene related to the moving process according to the moving track, for example, scenes with position points, such as an intersection scene, a market scene and the like, can be used as the moving scene.

When determining the scene sequence, the sequence of each target scene can be determined as the sequence of the target scene in a default sequence, namely according to the moving track of the target object. The sequence of the user visual configuration can also be received, and the playing of the video can be flexibly controlled through the configuration.

As an optional implementation manner of this embodiment, the acquiring the next video stream includes: determining a next target moving scene of the certain moving scene according to the sequence from the scene sequence; and acquiring the video stream of the next target mobile scene.

In this optional implementation manner, before the currently played video stream is finished, a next moving scene of the current moving scene may be determined based on the sequence of the moving scenes, and after the determining, a monitoring device under the next moving scene may be called, and based on the determined monitoring device, the next played video stream is determined. And after the currently played video stream is finished, the next played video stream can be determined to be decoded. When playing the current frame, the video stream of the next frame is acquired, and when playing the image of the next frame, decoding is only needed, and the video stream of the image of the next frame is not needed to be acquired. The speed of video playing is improved.

Further, after the video stream of a mobile scene is displayed, a judgment can be made based on the sequence to judge whether the element in the sequence is the last element, and if so, the playing is finished.

As an optional implementation manner of this embodiment, the step of obtaining the video stream of a certain mobile scene after receiving the video stream playing request of the certain mobile scene triggered by the user from the interface includes parsing the request after receiving the video stream playing request of the certain mobile scene triggered by the user from the interface, to determine that the certain mobile scene belongs to a certain mobile scene or is a certain batch of mobile scenes.

In this alternative implementation, a scene sequence includes a plurality of mobile scenes, where the mobile scenes may be represented by unique identifiers, and the unique identifiers may be mapped with corresponding monitoring devices. After determining the sequence, the user can select a scene to be played, and the scene can be selected one or a batch, if the scene is selected one or a plurality of scenes according to continuous movement, or can be a moving scene with intervals, if the scene is an interval moving scene, the next moving scene is a scene which is adjacent to the last moving scene in the selected moving scenes.

Through the optional implementation mode, flexible video playing is realized.

As an optional implementation manner of this embodiment, when receiving a video stream playing request of a certain mobile scene triggered by a user from an interface, obtaining a video stream of the certain mobile scene, and displaying the video stream includes: and acquiring a plurality of monitoring videos related to the certain mobile scene, determining the video related to the certain mobile scene in all monitoring videos at the same time, and taking all monitoring videos related to the video at the same time as the video stream of the current certain mobile scene.

In this optional implementation manner, as described above, one mobile scene may correspond to one or more monitoring devices, and each monitoring device may generate a monitoring video, so when a video stream of a certain mobile scene is acquired, multiple monitoring videos may be acquired simultaneously.

According to the method, the next video stream can be acquired while the current video stream is displayed, so that when the next frame of video is played, only the video stream of the image of the next frame is needed to be decoded, the video stream of the image of the next frame is not needed to be acquired first and then decoded, and the efficiency of playing the video is improved.

The above method for playing video provided by one or more embodiments of the present application is based on the same concept, and the present application further provides a corresponding apparatus for playing video, as shown in fig. 2.

Optionally, the apparatus further comprises:

a moving scene determining unit configured to acquire a moving track of a target object and determine a moving scene related to the target object according to the moving track;

Optionally, the acquiring the next video stream includes:

and acquiring the video stream of the next target mobile scene.

The present application also provides a computer readable medium storing a computer program operable to perform the method provided in fig. 1 above.

The application also provides a schematic block diagram of the electronic device shown in fig. 3, which corresponds to fig. 1. At the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile storage, as described in fig. 3, although other hardware required by other services may be included. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the program to implement a video playing method as described in fig. 1. Of course, other implementations, such as logic devices or combinations of hardware and software, are not excluded from the present application, that is, the execution subject of the following processing flows is not limited to each logic unit, but may be hardware or logic devices.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.

The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being functionally divided into various units, respectively. Of course, the functions of each element may be implemented in the same piece or pieces of software and/or hardware when implementing the present application.
