Detailed description of the preferred embodiments
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
In the related art, the arrangement mode of the video windows in the full-screen page of the equipment is not flexible enough, and the switching mode between the video windows is also not flexible enough, so that the video watching experience of a user is reduced. In view of this, the present invention may provide a video playing method, which may record a corresponding relationship between each video window and a full-screen page and an arrangement order of each window in the full-screen page by using a corresponding relationship table and a linked list, and generate and switch the full-screen page and the video window based on the corresponding relationship table and the linked list, so as to improve the arrangement flexibility of the video window in the full-screen page and improve the switching flexibility of the video window.
For easy understanding, the embodiment of the present invention first introduces a full screen page, a video window, a correspondence table, and a linked list. The full screen page refers to page content capable of completely covering a display interface of equipment, a plurality of video windows can be arranged in the page, and the video windows can play videos at the same time, so that the embodiment of the invention can realize the effect of simultaneously playing a plurality of videos in a single full screen page. Furthermore, a plurality of full-screen pages can be preset, the pages are provided with a plurality of video windows and can be switched randomly, and further, the embodiment of the invention can realize the fast switching of the plurality of video windows in a full-screen page switching mode so as to remarkably improve the switching flexibility among the video windows. It should be noted that, the embodiment of the present invention does not limit the number of full screen pages and the number of video windows that can be included in each full screen page, and these numbers can be set according to the actual application requirements; the embodiment of the present invention also does not limit whether the number of the video windows included in each full-screen page is the same, and can be set according to the actual application requirements, for example, convenience for setting up the promotion can be achieved, the number of the video windows included in each full-screen page can be set to the same value, for example, flexibility of display of the video windows can be improved, and the number of the video windows included in each full-screen page can also be set to different values.
Further, in order to prevent the arrangement of the video windows from being disordered, the corresponding relationship between each video window and the full-screen page and the arrangement sequence of each video window in the full-screen page should be specially recorded. Therefore, the embodiment of the invention particularly sets a corresponding relation table and a linked list. The corresponding relation table is used for recording the corresponding relation between each video window and each full screen page, namely recording which video windows belong to which full screen page. The corresponding relation table can be in a form of a table or a two-dimensional array, elements in the array are numbers of video windows, a first dimension of the array corresponds to a full-screen page, a second dimension of the array corresponds to the video windows contained in each full-screen page, and the specific form of the array can be set according to actual application requirements. The linked list is not only used for recording window information (such as the serial number of the video window, video stream information of the played video, etc.) of each video window, but also can record the arrangement sequence among each video window through the linked list structure. Specifically, a plurality of nodes which are connected in sequence are arranged in the linked list, the nodes correspond to the video windows one by one and are used for recording window information of each video window, and the arrangement sequence of the video windows in the full-screen page is recorded by the aid of the connection sequence among the linked lists. For easy understanding, please refer to fig. 1, fig. 1 is a schematic diagram of a linked list according to an embodiment of the present invention, in which a root node is a start node of the linked list, and nodes 1, 2, and 3 are respectively used to store window information of video windows 1, 2, and 3. Assuming that a full-screen page only includes video windows 1, 2, and 3, the arrangement order of the three windows in the full-screen page is, according to the node order: video window 1, video window 2, video window 3. Fig. 2 is a schematic diagram of a first full screen page provided by an embodiment of the present invention, and it can be seen that the three video windows are arranged from top to bottom according to the above sequence.
Further, it can be understood that the above correspondence table and the linked list should be initialized before generating each full screen page and video window. It should be noted that, before initializing the correspondence table and the linked list, the total number of video windows, the total number of full-screen pages, and layout information of each full-screen page should be determined, where the layout information may include, for example, the number of video windows that each full-screen page can accommodate, and then the linked list may be initialized according to the total number of video windows, each full-screen page may be determined according to the total number of full-screen pages, and the correspondence between each video window and each full-screen page may be established according to the number of video windows that each full-screen page can accommodate. The embodiment of the invention does not limit the determination mode of the total number of the video windows, the total number of the full-screen pages and the layout information, for example, the determination mode can be preset, can also be input by a user independently, and can be set according to the actual application requirements. In the embodiment of the present invention, in order to improve the initialization efficiency and reduce the use threshold of the user, the total number of the video windows, the total number of the full-screen pages, and the layout information may be preset information. It should be noted that, in the using process, the user may still modify and adjust the total number of the video windows, the total number of the full screen pages, and the layout information to meet the use requirement, for example, add video windows, full screen pages, or adjust the layout information. Further, the embodiment of the present invention does not limit the initialization order of the correspondence table and the linked list, and for example, the correspondence table may be initialized first, or the linked list may be initialized first. In order to improve the initialization efficiency, the embodiment of the invention initializes the linked list at first, and then determines the corresponding relation between each video window and the full screen page in sequence according to the determined arrangement sequence of each video window in the linked list. Specifically, when initializing the linked list, the total number of predetermined video windows may be obtained, the total number is used as the number of nodes to create the linked list, and then window information is added to each node of the linked list to complete initialization of the linked list. Then, when initializing the corresponding relationship, the corresponding relationship between each video window and each full-screen page can be determined in sequence according to the total number of the full-screen pages, the number of the video windows capable of being accommodated by each full-screen page and the sequence of the nodes of each video window in the linked list, and the corresponding relationship is recorded to the corresponding relationship table, so as to complete the initialization of the corresponding relationship table.
Furthermore, it should be noted that, in the embodiment of the present invention, it is not limited whether the preset layout information corresponding to each full screen page is the same, and the preset layout information may be set according to the actual application requirements, for example, for convenience, the same preset layout information may be set for each full screen page; for example, to improve layout flexibility, different preset layout information may be set for each full screen page. Furthermore, besides the number of video windows that can be accommodated by each full-screen page, the preset layout information may further include placeable positions where the video windows can be placed in each full-screen page, so as to further enrich the layout manner of the video windows in the full-screen page. It will be appreciated that the number of placeable locations should be the same as the number of video windows that a full screen page can accommodate. For further understanding, please refer to fig. 3, fig. 3 is a schematic diagram of a second full-screen page provided by the embodiment of the present invention, in which two full-screen pages are shown, wherein three dashed boxes in full-screen page 1 correspond to three positions where video windows can be placed, and six dashed boxes in full-screen page 2 correspond to six positions where video windows can be placed, and related information (such as coordinate information, size, and the like) of these positions can be recorded by preset layout information. Furthermore, when arranging the video windows, the video windows can be sequentially arranged to the placeable positions. For example, referring to fig. 4, fig. 4 is a schematic diagram of a third full screen page according to an embodiment of the present invention, for the placeable positions shown in fig. 3, video windows may be placed according to the sequence shown in fig. 4, where in full screen page 1, the video windows may be sequentially arranged to the three placeable positions from top to bottom; in the full screen page 2, the video windows can be sequentially arranged to the six placeable positions from left to right and then from top to bottom. Of course, the arrangement sequence shown in fig. 4 is only an example, and the actual arrangement sequence can be freely set according to the application requirements. In addition, the size of each placeable position and the specific position of the placeable position in the full-screen page are not limited in the embodiment of the invention, and can be set according to the actual application requirements, for example, the placeable positions can be flexibly set so as to place a larger window and a plurality of smaller windows in the same page, or place a plurality of rows and columns of windows with the same size in the same page, and other various arrangement modes.
Based on the above descriptions of the full screen page, the video window, the corresponding relationship table and the linked list, the video playing method provided by the embodiment of the present invention is described in detail below. Referring to fig. 5, fig. 5 is a flowchart of a video playing method according to an embodiment of the present invention, where the method includes:
s501, when a page switching event is detected to be triggered, acquiring a preset linked list and a corresponding relation table; the nodes connected in sequence in the linked list are used for sequentially storing the window information of each video window, and the corresponding relation table is used for storing the corresponding relation between each video window and the full-screen page.
In an embodiment of the present invention, the page switching event is used to switch a visible full screen page displayed by the current device, for example, to a previous full screen page, a next full screen page, or a specific full screen page. When detecting that a page switching event is triggered, the embodiment of the invention needs to perform rendering generation on a full screen page to be switched corresponding to the event so as to replace the current visible full screen page by using the full screen page to be switched. It should be noted that the embodiment of the present invention does not limit the specific triggering manner of the page switching event, for example, the specific operation (such as a screen touch operation, a physical button pressing operation, and the like) performed by the user may be detected, or the page switching event may be automatically triggered when the video playing is detected to be finished or the screen switching time is reached, and the triggering manner may be set according to the actual application requirement. Further, the chain table and the corresponding relation table are required to be used for generating the full screen page to be switched, and as described above, the chain table and the corresponding relation table should be initialized before the full screen page and the video window are generated, so that the chain table and the corresponding relation table should be initialized first before the page is generated, displayed and switched.
Based on this, before detecting that the page switching event is triggered, the method may further include:
step 11: acquiring the total number of video windows, the total number of full-screen pages and preset layout information; the preset layout information comprises the number of video windows which can be accommodated in each full-screen page;
step 12: creating a linked list by taking the total number of the video windows as the number of the nodes, and adding window information into each node of the linked list;
step 13: and according to the total number of the full-screen pages, the number of the video windows capable of being accommodated by each full-screen page and the sequence of the nodes of each video window in the linked list, sequentially determining the corresponding relationship between each video window and each full-screen page, and recording the corresponding relationship into a corresponding relationship table.
After the initialization of the corresponding relation table and the linked list is completed, the embodiment of the invention can complete the generation, display and switching of the full screen page, for example, a first full screen page is generated and output based on the corresponding relation table and the linked list, and when a page switching event is detected to be triggered, a full screen page to be switched is generated by using the corresponding relation table and the linked list, and the currently visible full screen page is replaced by using the full screen page to be switched.
S502, determining a full-screen page to be switched corresponding to the page switching event, searching a target video window corresponding to the full-screen page to be switched according to the corresponding relation table, and determining target window information and an arrangement sequence of each target video window by using a linked list.
As described above, the correspondence table is used to record the correspondence between the video windows and the full-screen pages, and the linked list is used to record the window information of each video window and the arrangement order of each video window in the full-screen pages, so that when the full-screen pages to be switched corresponding to the page switching event are determined, the corresponding target video windows can be queried in the correspondence table, and the target window information and the arrangement order of each target video window are determined by using the linked list, so as to generate and sequentially arrange each target video window according to the target window information and the arrangement order.
S503, generating a full screen page to be switched, generating target video windows according to the target window information, and arranging all the target video windows in the full screen page to be switched according to the arrangement sequence;
as described above, since the preset layout information may further include placeable positions of the video windows in the full-screen page, after the arrangement order is determined, the actual positions of the target video windows in the full-screen page may be further determined based on the placeable position order, and the target video windows may be placed in the actual positions.
Based on this, the preset layout information further includes placeable positions of the video windows in the full screen page, and the arranging of the target video windows in the full screen page to be switched according to the arrangement sequence may include:
step 21: determining the actual position of each target video window in the full screen page to be switched according to the arrangement sequence and the placeable position sequence;
step 22: and arranging the target video window to a full screen page to be switched according to the actual position.
It should be noted that the embodiment of the present invention does not limit the generation manners of the full screen page to be switched and the target video window, wherein the full screen page to be switched may be rendered in a manner of rendering a ViewGroup container, and the target video window may be rendered in a manner of rendering a TextureView layer, which may refer to related technologies of visualization interface rendering.
S504, outputting the full screen page to be switched, and playing videos in the target video windows.
It should be noted that the video information played by each target video window may be obtained from the corresponding linked list. The embodiment of the invention does not limit the setting mode of each video information and can set according to the actual application requirement.
Further, when a page switching event is triggered, the video may still be played in the currently displayed visible full-screen page, and at this time, in order to avoid wasting computing resources, the video played in the visible full-screen page may be paused. Of course, besides the pause processing, the embodiment of the invention can also buffer the last frame of image frame played by each video window in the visible full-screen page, so that when the user switches back to the page next time, the buffered image frame is displayed as the cover of each video window, the smoothness of the page when switching back and forth is improved, and the use experience of the user can be further improved. It will be appreciated that the image frames described above may be stored in nodes corresponding to video windows.
Based on this, after detecting that the page switching event is triggered, the method may further include:
step 31: determining a currently displayed visible full-screen page and a visible video window contained in the page;
step 32: pausing the video played by each visible video window, and caching the currently displayed image frame of each visible video window to a corresponding node;
correspondingly, after arranging each target video window in the full screen page to be switched according to the arrangement sequence, the method further comprises the following steps:
step 41: when the image frames are cached in the nodes of the target video window, the image frames of the target video window are set in the target video window, and the step of outputting the full screen page to be switched is executed after the setting is finished.
It can be understood that if the full-screen page to be switched has been output and displayed previously, each target video window in the page may have a corresponding image frame cached therein, so the embodiment of the present invention may attempt to extract the image frame from the node of the target video window, and if the extraction is successful, may set the image frame as a cover image of the target video window, and output and display the full-screen page after the setting is completed.
Based on the embodiment, when the page switching event is detected to be triggered, the preset linked list and the corresponding relation table can be obtained, wherein each node sequentially connected in the linked list is used for sequentially storing the window information of each video window, and the corresponding relation table is used for storing the corresponding relation between each video window and the full-screen page; then, the invention can determine the full screen page to be switched corresponding to the page switching event, determine the target video window corresponding to the full screen page to be switched according to the corresponding relation table, and can determine the target window information and the arrangement sequence of each target video window by using the linked list, in other words, the linked list is not only used for storing the window information of the video windows, but also can be used for determining the arrangement sequence of each video window in the full screen page by the sequence of the nodes of each video window in the linked list; further, the full-screen page to be switched is generated, the target video windows are generated according to the target window information, the target video windows are arranged in the full-screen page to be switched according to the previously determined arrangement sequence, and the full-screen page to be switched is finally output so as to complete the switching of the video windows. Simply speaking, the invention can flexibly set video windows in a full-screen page, can record the corresponding relation between the full-screen page and each video window by using the corresponding relation table, and can record the window information of the video windows and the arrangement sequence in the full-screen page by using the linked list; in addition, the method and the device can quickly realize the switching of the video window in a full-screen page switching mode, further can remarkably improve the arrangement flexibility and the switching flexibility of the video window in the full-screen page of the mobile equipment, and can remarkably improve the use experience of a user.
Based on the embodiment, the embodiment of the invention can realize the switching between full-screen pages in a touch operation mode; in addition, a more flexible video window control mode can be realized through a touch operation mode. The following describes three touch operation modes provided by the embodiment of the present invention in detail.
Firstly, the user can realize flexible switching between full-screen pages in a screen sliding mode. Specifically, the embodiment of the present invention may determine whether a touch point can be detected in the display device, and if the touch point can be detected, the position of the touch point in the display screen and the corresponding touch action may be further determined. Then, the embodiment of the present invention needs to determine whether the touch action corresponding to the touch point is a horizontal sliding action, for example, sliding horizontally to the left, or sliding horizontally to the right; in addition, in order to avoid misoperation, the embodiment of the present invention further needs to determine whether the sliding distance corresponding to the touch point is greater than a preset distance. In this way, if it is determined that the touch point corresponds to the horizontal sliding action and the corresponding sliding distance is greater than the preset distance, it can be determined that the user has performed the page switching operation, and the page switching event can be triggered. It can be understood that when the horizontal sliding motion is horizontal leftward sliding, the corresponding switch can be made to the previous page, and when the horizontal sliding motion is horizontal rightward sliding, the corresponding switch can be made to the next page.
Based on this, the method may further comprise:
step 51: when a touch point is detected in the display equipment, determining a position and a touch action corresponding to the touch point;
step 52: and when the touch action is determined to be a horizontal sliding action and the sliding distance is greater than a preset distance, triggering a page switching event.
For convenience of understanding, please refer to fig. 6, where fig. 6 is a schematic diagram of full screen page switching according to an embodiment of the present invention, and the embodiment of the present invention may implement switching between a current visible screen and an invisible screen by performing a horizontal sliding motion on a display device. It should be noted that, the embodiment of the present invention does not limit the specific value of the preset distance, and the preset distance may be set according to the actual application requirement.
Furthermore, the user can select a specific video window in the full screen page by a long-press mode, and can adjust the position of the window in the full screen page by a dragging mode. Specifically, in the embodiment of the present invention, if a touch point can be detected in the display device, and a pressing action (that is, a pressing action but no movement occurs) corresponding to the touch point can be determined, it can be determined whether a duration of the action holding exceeds a preset duration. If the holding time length exceeds the preset time length, the touch point corresponding to the long-time pressing action can be determined, and at this time, the embodiment of the present invention can set the target video window where the touch point is located as the main video window, which means that the window has been selected and can be moved and adjusted. Then, before the touch point is determined not to be released, the main video window can be moved according to the position of the touch point, and the arrangement sequence between the main video window and other video windows in the full-screen page can be adjusted according to the moving position of the main video window; and when the touch point is determined to be released, stopping moving the main video window, and placing the main video window at the current position. Of course, the position change means that the arrangement order of the main video window and other video windows is changed. In order to record the change, the corresponding position adjustment of the node of the main video window in the linked list is needed.
Based on this, after determining the position and the touch action corresponding to the touch point, the method may further include:
step 61: when the touch action is determined to be a pressing action and the action holding duration exceeds the preset duration, setting a target video window where the touch point is located as a main video window;
step 62: when the touch point is determined not to be released, moving the main video window according to the position of the touch point, and adjusting the arrangement sequence between the main video window and other target video windows according to the moving position of the main video window;
and step 63: and when the touch point is determined to be released, stopping moving the main video window, and adjusting the sequence of the nodes of the main video window in the linked list according to the adjusted arrangement sequence.
It should be noted that, the embodiment of the present invention may mark the video window as the main video window by adding a mark to the video window. In addition, other visual markers may be added to the main video window to specifically mark out that the window may be adjusted and moved for ease of use by the user. In addition, the embodiment of the invention does not limit the specific value of the preset duration, and can be set according to the actual application requirement.
Further, the user may also enlarge a video window by continuously clicking on the video window. Specifically, if a touch point can be detected in the display device and a click action (i.e., pressing and quickly lifting) corresponding to the touch point can be determined, the embodiment of the present invention can further determine whether the number of times that a target video window where the touch point is located is continuously clicked (i.e., the interval between adjacent click actions is short) exceeds a preset number of times. If it can be determined that the number of consecutive clicks has exceeded a preset number, the target video window may be set as a main video window, and the main video window is enlarged to a preset size.
Based on this, after determining the position and the touch action corresponding to the touch point, the method may further include:
step 71: when the touch action is determined to be a click action, judging whether the number of times of continuous clicks of a target video window where the touch point is located exceeds a preset number of times;
step 72: if so, setting the target video window where the touch point is located as a main video window, and amplifying the main video window to a preset size.
It should be noted that, the embodiment of the present invention does not limit the specific value of the preset number of times, for example, the number of times may be two; the embodiment of the invention also does not limit the specific preset size and can be set according to the actual application requirements.
Based on the above embodiments, the embodiments of the present invention can implement the switching between full-screen pages, the moving of the video window, and the size adjustment by a touch operation manner, and can further improve the flexibility of the switching and adjustment of the video window.
Based on the above embodiments, it is considered that playing multiple videos simultaneously in a single full screen page easily occupies a large amount of computing resources of the device. In order to avoid the equipment jam caused by resource occupation, the embodiment of the invention can also self-adaptively adjust the video parameters corresponding to the currently played videos according to the use condition of the equipment computing resources so as to reduce the resource occupation. In a possible case, after the video playing is performed in each target video window, the method may further include:
step 81: acquiring the CPU utilization rate, the CPU work core number and the memory utilization rate;
step 82: and adjusting the video parameters corresponding to the videos played by the target video windows according to the CPU utilization rate, the CPU work core number and the memory utilization rate.
The embodiment of the present invention does not limit specific video parameters, and the specific video parameters may be, for example, resolution, code rate, and the like. The embodiment of the present invention does not limit how to adjust the video parameters according to the CPU utilization, the CPU core count, and the memory utilization, but it can be understood that if the CPU utilization and the memory utilization are higher and the CPU core count is more, the video parameters should be adjusted downward, that is, the video quality should be reduced, so as to reduce the CPU utilization and the memory utilization, and reduce the CPU core occupied by playing the video. The following description will be made based on a specific example. If nine windows currently playing videos exist, the utilization rates of a CPU and a memory can be obtained through a system self-contained method, if the utilization rate of the CPU exceeds 50%, the working core is larger than 2 cores, the utilization rate of the memory reaches 70%, and the memory occupation reaches 2g, 5 windows are automatically switched into auxiliary code streams, namely the video quality of the 5 windows is reduced; if the CPU utilization rate exceeds 60%, the work core is larger than 2 cores, the memory utilization rate reaches 80% and the memory occupation reaches 2g, only the first window plays the main code stream at the moment, other windows are switched into the auxiliary code stream, namely, only one window is ensured to play with higher image quality, and other windows are adjusted to have lower image quality, so that the use of the mobile phone memory and the CPU is reduced.
