Detailed Description
The present invention is described below based on examples, but the present invention is not limited to only these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. The present invention will be fully understood by those skilled in the art without the details described herein. Well-known methods, procedures, and flows have not been described in detail so as not to obscure the nature of the invention. The figures are not necessarily drawn to scale.
Fig. 1 is a flowchart of a picture playing method according to an embodiment of the present invention, where the picture playing method includes:
step S102, a plurality of sub-pools of a picture pool are filled with a plurality of pictures to be played in turn in a playing task, and in the process of loading the pictures to be played in the picture pool, the following steps are executed:
step S104, a recording step, including: recording the number of pictures to be played in a picture pool; the method comprises the steps of,
step S106, a playing step, comprising: when the number of the pictures to be played is recorded to be not smaller than the play start value, the pictures to be played in each sub-pool are started to be played according to the loading sequence of the sub-pools, and the pictures to be played which are fully loaded in each sub-pool are emptied after being played, wherein the play start value is smaller than the total number of the pictures to be played of the play task.
It should be noted that, a plurality of sub-pools of a picture pool are filled with a plurality of pictures to be played in the playing task in turn, that is, after a plurality of sub-pools are filled with one another in turn, another round of loading is performed after one round of loading is performed on all sub-pools until a plurality of pictures to be played in the playing task are all loaded, it should be understood that the last loaded sub-pool cannot be filled.
In the picture playing method provided by the invention, the plurality of sub-pools of the picture pool alternately load a plurality of pictures to be played in the playing task, so that the occupation of storage resources is saved, and the storage pressure of a browser is reduced; and the play start value is smaller than the total number of pictures to be played of the play task, so that all the pictures to be played of the play task do not need to be imported at a higher speed at one time, and the play can be started without loading all the pictures to be played of the play task into the picture pool, namely, the technical effects of shortening the loading time of the pictures before playing and relieving the running pressure of the browser are achieved by reducing the loading quantity of the pictures before playing, and the technical problems that the playing start is slow and the browser is easy to crash when a large number of pictures are continuously played by the traditional picture playing method are solved.
Fig. 2 shows a flowchart of one implementation of the picture playing method in the case where a plurality of sub-pools of the picture pool are not considered, but the picture pool is taken as a loading unit. Referring to fig. 2, the picture playing method includes:
step S201, assigning zero to the initial loading index;
step S202, extracting an unextracted picture to be played in the playing task to load the extracted picture into a picture pool, and adding one to an initial loading index to obtain a current loading index;
step S203, judging whether the current loading index is not less than the play start value, wherein step S204 is executed under the condition that the current loading index is not less than the play start value;
step S204, playing the picture to be played in the picture pool; the method comprises the steps of,
step S205, judging whether the current loading index is smaller than the total number of pictures to be played, wherein the step S202 is executed after the current loading index is determined to be the initial loading index under the condition that the current loading index is smaller than the total number of the pictures to be played.
It should be noted that, after the step S203, if the current loading index is smaller than the play start value, no operation is performed; and step S205, if the current loading index is not less than (equal to) the total number of the pictures to be played after the judgment, loading is ended.
Step S204, the pictures to be played in the picture pool are played, namely, the current loading index is not less than the play start value, until all the pictures to be played in the play task are played.
In the above execution of the picture playing method, the capacity of the picture pool must not be smaller than the total capacity required by a plurality of pictures to be played in the playing task.
In an alternative embodiment, step S102, loading a plurality of sub-pools of a full picture pool with a plurality of pictures to be played in a play task in turn, includes:
acquiring a plurality of storage data corresponding to a plurality of pictures to be played in a playing task;
sequentially analyzing the plurality of storage data to sequentially obtain the reading addresses used when each picture to be played in the playing task is called; the method comprises the steps of,
after each reading address is obtained, the reading address is loaded into a picture pool so as to read a plurality of pictures to be played in the playing task through the reading address for playing.
Specifically, the storage data may be a picture storage address, for example, a local storage address: imaging/1. Png, and, network storage address: http://10.10.10.245:80/images/1.Png. It should be noted that, the storage address of the picture and the read address directly used by the calling picture are different in data format, so after the storage data of the picture is obtained, the storage data can be firstly analyzed to obtain the read address used by the calling picture, and the picture can be directly read by using the read address in the picture pool under the condition that the picture needs to be played, so that the reading speed of the picture is not affected.
The playing task can store a plurality of storage data according to a preset playing sequence through a picture address set, and the length of the picture address set is the number of the storage data in the picture address set, namely the number of a plurality of pictures to be played in the playing task. In this case, acquiring the plurality of storage data includes acquiring a set of picture addresses to acquire the plurality of storage data; and sequentially analyzing the plurality of storage data, including sequentially analyzing the plurality of storage data according to a preset playing sequence, so that a plurality of pictures to be played of the playing task can be conveniently and orderly loaded through the corresponding picture address set of the playing task.
In the embodiment of the invention, compared with the picture, the information quantity of the stored data and the read address is smaller, so that the stored data is obtained more rapidly, the read address is stored more rapidly in the picture pool, and the picture loading is conveniently and rapidly realized by obtaining the stored data and loading the read address.
In an optional embodiment, the picture playing method further includes:
judging whether the total number of pictures to be played is larger than a preset threshold value, wherein,
under the condition that the total number of the pictures to be played is not greater than a preset threshold value, after the pictures to be played in the playing task are loaded in the picture pool, starting to play the pictures to be played in the picture pool;
and under the condition that the total number of the pictures to be played is larger than a preset threshold value, executing a recording step and a playing step in the process of loading the pictures to be played in the picture pool.
It should be noted that, the preset threshold is a value that ensures that the picture loading time is less and the play is smoother when the total number of pictures to be played is greater than the preset threshold. In each example of playing a plurality of pictures, the number and the size of the pictures to be played are not completely consistent, so that in different examples, the preset threshold value can be set to different values.
After a large number of examples of playing a plurality of pictures are tested, the preset threshold value can be set to be 100, and under the condition that the total number of the pictures to be played is larger than the preset threshold value, the picture loading time is short and the playing is smooth.
In the embodiment of the invention, the demarcation is performed through the preset threshold value, wherein the total number of the pictures to be played is smaller under the condition that the total number of the pictures to be played is not greater than the preset threshold value, so that all the pictures to be played in the playing task can be rapidly loaded without adopting the recording step S104 and the playing step S106, and the playing flow is simplified; and when the total number of the pictures to be played is greater than the preset threshold, the total number of the pictures to be played is larger, so that the recording step S104 and the playing step S106 are adopted to simultaneously ensure the quick start and the no-clip playing of the picture playing.
In an optional embodiment, the plurality of sub-pools in the picture pool includes a first picture pool and a second picture pool, and the capacities of the first picture pool and the second picture pool are smaller than the total number of pictures to be played, and step S102, loading the plurality of sub-pools of the picture pool with the plurality of pictures to be played in turn in the play task, includes:
filling a first picture pool and a second picture pool with a plurality of pictures to be played in the playing task in turn; the method comprises the steps of,
and after the first picture pool plays the full picture to be played, the first picture pool is emptied, and after the second picture pool plays the full picture to be played, the second picture pool is emptied.
Fig. 3 is a flowchart of a picture playing method performed under the condition that the number of the plurality of sub-pools in the picture pool is two (i.e., the first picture pool and the second picture pool), and the capacities of the first picture pool and the second picture pool are both the preset capacity m. Referring to fig. 3, loading a plurality of pictures to be played in a playing task in turn to fill a first picture pool and a second picture pool, including:
step S301, a value assigning step, namely assigning zero to an initial loading index and assigning one to an initial recording round n.
Step S302, a loading step, in which an unextracted picture to be played in a playing task is extracted and loaded into a target picture pool, the sequence number of the target picture pool is 2-n%2 which is the difference between two target values and a first target value, and the first target value is n%2 of the remainder of the initial recording round n and two divisions; and a loading recording step, namely adding one to the initial loading index to obtain the current loading index.
For example, if the initial recording round is 1, the target picture pool is the first picture pool; if the initial recording round is 2, the target picture pool is a second picture pool; if the initial recording round is 3, the target picture pool is the first picture pool again, and so on, and as the recording round increases, the target picture pool is selected from the first picture pool and the second picture pool in turn.
Step S303, judging whether the current loading index is equal to a second target value, wherein the second target value is the product n x m of the initial recording round and the preset capacity.
Step S304, a round recording step, namely adding one to the initial recording round to obtain the current recording round under the condition that the current loading index is equal to a second target value, and determining the current recording round as the initial recording round;
step S305, returning to the step, and determining the current loading index as the initial loading index and returning to the step of loading execution until a plurality of pictures to be played in the playing task are loaded under the condition that the current loading index is not equal to the second target value or after the round recording step is completed.
It should be noted that, determining whether the plurality of pictures to be played in the playing task are loaded can be implemented by the method included in the step S205 after the step S302, that is, determining whether the current loading index is smaller than the total number of the pictures to be played, if so, indicating that the plurality of pictures to be played in the playing task are not loaded; and if the number of the pictures to be played is not less than the total number of the pictures to be played, indicating that the pictures to be played in the playing task are loaded, and ending loading.
In the embodiment of the invention, the purpose of filling the first picture pool and the second picture pool in turn is realized by combining the parameters of the initial recording round, the current recording round, the initial loading index and the current loading index and the association processing of the initial recording round and the target picture pool sequence number.
In this embodiment, the playing step may be performed after step S302, where the playing step specifically includes:
step S306, judging whether the current loading index is not less than the play start value;
step S307, sequentially playing the pictures to be played in the target picture pool according to the preset playing sequence under the condition that the current loading index is not less than the playing start value
It should be noted that, after the step S306, if the current loading index is smaller than the play start value, no operation is performed.
In an alternative embodiment, the currently loaded picture pool (i.e. the target picture pool) in the first picture pool and the second picture pool is changed to load the pictures to be played after the pictures to be played are loaded and when the playing quantity of the currently loaded pictures to be played is equal to the pool changing threshold value. Fig. 4 shows a flowchart of a picture playing method in this embodiment, and the pool-changing threshold value adopts a play start value. Referring to fig. 4, the picture playing method is to adjust the steps S301 to S307 as follows:
step S301, a value assigning step, which further comprises assigning zero to the play index;
step S307, after starting to play the pictures to be played in the picture pool, adding one to the play index per play of one picture to be played to obtain an updated play index; the method comprises the steps of,
if the current load index is equal to the second target value after the determination in step S303, no operation may be performed (i.e., step S304 shown in fig. 3 is not performed), but the following steps are performed after step S307:
step S308, judging whether a first condition and a second condition are simultaneously met, wherein the first condition is that the updated play index is not less than the sum of a third target value and a play start value, the second condition is that the current loading index is equal to the second target value, the third target value is the product of a target difference value and a preset capacity m, and the target difference value is the reduction of 1 of an initial recording round n;
step S309, in the case where the first condition and the second condition are simultaneously satisfied, the initial recording round is added by one to obtain the current recording round, and the current recording round is determined as the initial recording round and then the step S302 is executed.
