Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict.

Unless otherwise defined, technical or scientific terms used in the disclosure of the embodiments of the present disclosure should have the ordinary meaning as understood by those having ordinary skill in the art to which the present invention belongs. The use of "first," "second," and similar terms in the embodiments of the disclosure is not intended to indicate any order, quantity, or importance, but rather to distinguish one element from another. The word "comprising" or "comprises", and the like, means that a particular element or item appears in front of the word or is detected by mistake, and that the word or item appears after the word or item and its equivalents, but does not exclude other elements or misdetections.

In this specification, for convenience, terms indicating orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like are used to explain positional relationship of constituent elements with reference to the drawings, only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. The positional relationship of the components is changed as appropriate in accordance with the direction in which each component is described. Therefore, the words described in the specification are not limited to the words described in the specification, and may be replaced as appropriate.

For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or indirectly through intervening components, or may be interconnected between two elements. To those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in conjunction with specific situations.

In the process of playing materials (pictures, videos, characters and the like), the controller controls the playing component to play the materials, the playing time of the playing component for playing the materials is calculated in advance, when the playing time calculated in advance is reached, the controller can forcibly terminate the playing of the playing component, and because the loading time of each material is uncertain, the playing time does not usually contain the loading time of the material, the problem of incomplete playing of the materials exists. In addition, when each playing component plays the material, the playing components are independently controlled by the corresponding controllers, when a plurality of playing components play the material, because the playing components are independently processed by the controllers corresponding to the playing components in the process of playing the material and the controllers are not mutually communicated, the playing material of each playing component lacks linkage, when the playing components play the material on the screen, the playing components can be divided into two situations that the playing components play simultaneously or the playing components play sequentially, no matter which playing situation, the screen playing picture is an organic whole, when one or more playing components play the material, other playing components can also play normally, and the screen playing picture can be discontinuous or not a real playing effect, resulting in a poor user experience.

In order to solve the problem of poor user experience in playing the existing material, an embodiment of the present disclosure provides a playing control method, which is applied to a playing control device, and as shown in fig. 1, the method may include:

step 1: generating a central control controller and a plurality of sub-controllers;

the sub-controller plays the material according to the instruction of the central controller, starts the timer to start timing when the material to be played starts playing, and finishes playing the material to be played currently when the timer reaches the playing duration of the material to be played.

In an exemplary embodiment, each sub-controller plays the material under the control of the central controller, as shown in fig. 2, may include:

step A3: the sub-controller obtains the next material to be played according to the own material list, and executes the step a 2.

In an exemplary embodiment, the information of the material to be played may include: the playing time, the type, the playing position and the attribute information of the material.

In an exemplary embodiment, when the type of the material to be played includes an image or a video, starting a timer to start timing when the material to be played starts to be played may include:

In an exemplary embodiment, the process of loading the material may include a process of acquiring the material to be played by the sub-controller and a process of rendering the material to be played by the sub-controller controlling the playing component.

In an exemplary embodiment, after notifying the central controller of the completion of the playing, the method may further include: and the central control controller sends a playing instruction to the sub-controller corresponding to the next material to be played according to the playing sequence of the materials played by the plurality of sub-controllers.

In an exemplary embodiment, when the central controller receives the notification of completing playing, and determines that there is no material to be played according to the material playing sequence corresponding to the sub-controllers, it indicates that all the sub-controllers complete playing of the material, and may end playing, or control one or more sub-controllers to play again according to a preset instruction and/or a user instruction.

In the embodiment of the disclosure, after each controller finishes playing all the materials, the central controller is notified, so that the central controller can effectively control the plurality of sub-controllers to play the materials in a linkage manner, and the problem that when one or more sub-controllers play the materials independently, the playing of the screen playing picture is discontinuous or not a real playing effect is avoided.

In the embodiment of the disclosure, the timer is started to time when the material to be played starts to be played, so that each material can be completely played, and the problem of incomplete playing of the material in the prior art is solved.

In an exemplary embodiment, the sub-controller obtains the material to be played, and may obtain the material to be played from the server according to the address and/or name of the material to be played in the own material list.

Optionally, the sub-controller may locally acquire the material to be played currently according to the name and/or address of the material to be played in the material list of the sub-controller.

In an exemplary embodiment, the controlling, by the sub-controller, the playback component to render the material to be played back may include: the sub-controller provides the materials to be played to the UI renderer, the UI renderer generates virtual pictures according to the materials to be played, the virtual pictures are provided to the system, the system generates display pictures, and the display pictures are displayed on a screen through the playing assembly. In an exemplary embodiment, the UI renderer generating the virtual screen from the material to be played may include: and the UI renderer generates a virtual picture according to the coordinates and the sizes of the materials in the material list.

In an exemplary embodiment, each sub-controller plays the material under the control of the central controller, and may further include: the central control controller acquires the playing state of the sub-controllers in real time and sends an operation instruction to the sub-controllers according to the playing state or an instruction from a user;

In an exemplary embodiment, the trick play state may include start, pause, complete. For example, the sub central controller may set three play states of start, pause, and complete by state values of a start sentence [ start () ], a pause sentence [ pause () ], and a complete sentence [ complete () ], respectively. In practical implementation, each sub-controller may actively provide the current play state to the central controller, and the central controller may also obtain the play state from the sub-controllers.

In an exemplary embodiment, the central controller can acquire the playing state of the sub-controllers in real time, and the sub-controllers execute corresponding operations according to the operation notification of the central controller, so that the playing state of the materials of the plurality of sub-controllers is performed under the control of the central controller, and the problem that the screen playing picture is not consistent or is not a real playing effect when one or more sub-controllers play abnormal pixels respectively and independently is avoided. For example, when the material played by one sub-controller is abnormal, the playing state is set to be paused, and when the central control controller obtains the paused playing state, the sub-controller is judged to be abnormal according to the playing duration and the playing sequence of the plurality of sub-controllers, and then the sub-controllers can be notified to pause the playing according to the paused state, or the sub-controllers which pause the playing are notified to continue the playing, so as to avoid that the playing picture is not a real playing effect.

In an exemplary embodiment, the central controller can also generate a corresponding operation notification according to an instruction from a user and send the operation notification to the sub-controllers, and the sub-controllers execute corresponding operations according to the operation notification, so that the flexibility and operability of material playing are improved.

In an exemplary embodiment, when the material to be played is a video, a thumbnail of a first frame picture of the video to be played is acquired, the thumbnail of the first frame picture of the video to be played is rendered and displayed on a screen, and after the first frame picture of the video to be played is rendered, the thumbnail of the first frame picture of the video to be played is removed, so that the phenomenon that a time interval between two playing of the material is too long due to too long time for loading the video to be played (namely, the time for acquiring and rendering the video) can be effectively avoided, and the visual effect is improved.

In an exemplary embodiment, in the method, during the playing of the current material, the method may further include: acquiring a next material to be played, and caching the next material to be played; correspondingly, when the next material to be played is played, the material to be played is obtained from the cache; therefore, the phenomenon that too long time interval exists between the playing of the two materials due to the fact that the time for obtaining the materials to be played (namely the material loading) is long is avoided, and the visual effect can be effectively improved. In practical solutions, the time for obtaining the material to be played from the buffer is between 5 ms and 20 ms, and the time interval that the human eye can distinguish is about 24 ms, so that the user cannot visually see that there is a time interval between the two played materials, i.e. the two materials are visually played continuously.

In an exemplary embodiment, the template types may include two types of fixed templates and non-fixed templates. In an exemplary embodiment, the fixed template types may include full screen (i.e., one-split screen), two-split screen, three-split screen, four-split screen, and the like; each of which may correspond to a playback component.

In an exemplary embodiment, the template types may include both fixed template and non-fixed template types.

Optionally, the fixed template types may include full screen (i.e., one split screen), two split screen, three split screen, four split screen, and the like; when the program information is edited on the webpage program editor, a user can select one of full screen, half screen, three-split screen and four-split screen in the fixed template type according to the requirement.

Optionally, the non-fixed template types may include custom template types; if the user-defined template type is selected when the webpage program editor edits the program information, the user can edit the information of the material according to the actual requirement, for example, the information of the position, the size and the like of the screen of the material can be edited. If the fixed template is selected when the program information is edited, the fixed template is directly loaded, and the material information (such as screen position, size and the like) of the fixed template does not need to be edited.

In an exemplary embodiment, the material list information may include information of the material to be played corresponding to the fixed template and information of the material to be played corresponding to the non-fixed position. The material list information comprises a plurality of material lists, and the material corresponding to each template type corresponds to the material lists in the material list information through material indexes.

Optionally, the information of the material to be played corresponding to the fixed template is information of the material corresponding to the fixed position in the fixed template. For example, when the template type is full screen, the full screen frame (i.e. one playing component) corresponds to the material list with the material index of 0; when the template type is two split screens, two split screen frames (i.e. two playing components) respectively correspond to the material list with the material indexes of 0 and 1.

Optionally, the information of the material to be played corresponding to the non-fixed position includes information of the material floating in the fixed template and information of the material of the non-fixed template. For example, the material floating in the fixed template may include text, a web page, a two-dimensional code, and the like, and during the playing process, the material corresponding to the information of the floating material may be displayed at a designated position above the fixed position material.

In an exemplary embodiment, editing program information on a web program editor may further include editing background music to generate background music information, and accordingly, the configuration file may further include the background music information. The background music information may include the size of the music file, the name of the music file, the type of the music file, the date of generation of the music file, and the address of the music file. For example, in the information of the background music, the size of the music file is 13342826 bytes, the name of the music file is Chengdu.mp 3, the type of the music file is AUDIO, the generation date of the music file is 2021-04-1213: 37:01 (13: 37: 1 second at 12.4.2021), and the address of the music file is static/images/video thread.png.

In an exemplary embodiment, the information of the material to be played in the material list includes a material type and a material playing time length; for example, the material type may be picture (IMAGE), VIDEO (VIDEO) or AUDIO (AUDIO), text, and the like. Optionally, the information of the materials contained in the materials of different types has a certain difference, for example, the material list of the text materials may further include information such as width, height, abscissa, ordinate, text size, font style, font color, background color, and scrolling direction; the material list of the two-dimension code material can comprise information such as the content, width, height, abscissa and ordinate of the two-dimension code.

In an exemplary embodiment, step 11 may further include: and acquiring a material of the program to be played. The configuration file and the materials are simultaneously issued to the local, so that the corresponding materials can be directly acquired from the local in the material playing process without being downloaded to a server, the playing efficiency can be improved, and the user experience is improved.

Step 12: generating a central control controller, generating a plurality of playing components according to the template types in the configuration file, generating a plurality of sub-controllers corresponding to the playing components in the process of generating the playing components, adding a material list corresponding to the playing components in the configuration file into the sub-controllers, and adding the sub-controllers into the central control controller.

For example, when the template type is a two-split screen, two playing components corresponding to the two-split screen are generated according to the template type in the configuration file, in the process of generating the two playing components of the two-split screen, two sub-controllers respectively corresponding to the two playing components are generated, a material list corresponding to the two playing components in the configuration file is added to the corresponding sub-controllers, and the two sub-controllers are added to the central controller.

In an exemplary embodiment, the addition of the sub-controllers to the central control controller is actually managed by adding the sub-controllers to the central control controller, so that the central control controller controls the linkage play of the materials among a plurality of sub-controllers.

As shown in fig. 4, a schematic diagram of a structure of a screen display playing component generated when the template type is two split screens, in fig. 4, view1 and view2 are playing components corresponding to the two split screens.

Fig. 5 is a schematic diagram illustrating a logical structure among the play component, the sub-controller, and the central controller when the template type is a custom template. In fig. 5, controllers 1 to ControllerN are a plurality of sub-controllers, controllers are central controllers, and views 1 to viewN are N playback elements respectively controlled by controllers 1 to ControllerN sub-controllers.

In an exemplary embodiment, the sub-controllers may include a base sub-controller and an extended sub-controller. In an exemplary embodiment, an extended sub-controller is a sub-controller that is extended on the basis of a base sub-controller.

In an exemplary embodiment, the expansion sub-controller may include one or more of a split screen sub-controller, a text sub-controller, and a PDF sub-controller. For example, a split screen (full screen) controller is FullscreenController, a text controller is TextController, and a PDF controller is PDFController; in the process of generating the split screen, a split screen material list in the configuration file is added to a Fullscreen controller, a character material list in the configuration file is added to a TextController, and a PDF material list in the configuration file is added to a PDFController.

In an exemplary embodiment, information of a play state, a play position, and the like may be contained in each sub-controller. In an exemplary embodiment, the play state may include start, pause, complete. For example, the sub central controller may set three play states of start, pause, and complete by state values of a start sentence [ start () ], a pause sentence [ pause () ], and a complete sentence [ complete () ], respectively. In an exemplary embodiment, each sub-controller may include a corresponding material list, and the play position indicates the material played the next in the material list, i.e., the material play order.

Step 13: after all the sub-controllers are added to the central control controller, the plurality of sub-controllers play the materials under the control of the central control controller; and after each sub-controller receives the playing instruction of the central control controller, the sub-controllers play the materials through the corresponding playing components according to the material lists of the sub-controllers, and after the last material is played, the central control controller is informed to finish playing.
