In the prior art, an Android Application Package (APK) of a terminal is often developed by adopting a hybrid development mode of embedded webview, and the APK can be applied to an advertisement design and playing system. However, in the process of playing advertisements through webview, pictures and videos are switched back and forth, and the phenomena of low fluency and even black screen occur.
In view of this, embodiments of the present invention provide a multimedia playing method and system, which are used to improve fluency of pictures and videos.
Fig. 1 is a flowchart of a method for playing multimedia according to an embodiment of the present invention, where the method includes:
s101: determining currently played materials in a multimedia stream, wherein the multimedia stream comprises a plurality of materials to be played which are sequentially arranged;
the currently played material may be any one of a plurality of sequentially arranged materials to be played included in the multimedia stream. The specific number of the plurality of materials to be played in the sequential arrangement included in the multimedia stream may be set according to the actual application requirement, and is not limited herein. The multimedia stream may be an advertisement, which may include four attributes including pictures, video, text, and web pages.
S102: preloading a next material to be played in the multimedia stream in the process of playing the material;
in the process of playing the currently played material, preloading a next material to be played in the multimedia stream, for example, the multimedia stream includes a material a, a material B, and a material C which are sequentially arranged, and in the process of playing the material a, preloading the material B, and in the process of playing the material B, preloading the material C. In addition, the next material to be played can be rendered in advance, and then the next material to be played is preloaded.
S103: and after the material is played, playing the next material to be played.
And after the material is played, playing the next material to be played. Due to the fact that the next material to be played is preloaded in the process of playing the material, the currently played material can be quickly switched to the next material to be played subsequently when the next material to be played is played, and therefore fluency in the process of playing the multimedia stream is improved when the currently played material is switched to the next material to be played, and the multimedia playing effect is guaranteed.
In the embodiment of the present invention, according to the specific attribute of the next material to be played, the following two implementation manners may be used to preload the next material to be played, but the present invention is not limited to the following two implementation manners.
It should be noted that, the playing of each material in the multimedia stream can be controlled by two video tags, i.e., video1 and video2, and two picture tags, i.e., img1 and img2, wherein each tag can have two states, i.e., a hidden state and a displayed state. For example, a video address in the multimedia stream is given to a corresponding video tag, and a video corresponding to the video address can be played, and for example, a picture address in the multimedia stream is given to a corresponding picture tag, and a picture corresponding to the picture address can be played. Therefore, the playing of each material in the multimedia stream can be realized through the video tag and the picture tag. Before playing the multimedia stream, corresponding initialization processing needs to be performed on each video tag and each picture tag, and each video tag and each picture tag are all adjusted to be in a hidden state.
In a first implementation manner, if the next material to be played is a video, step S102: in the process of playing the material, preloading a material to be played next in the multimedia stream, including:
and in the process of playing the material, associating the video address of the next material to be played with the video label in the hidden state, and rendering the next material to be played in a silent mode.
If the next material to be played is a video, in the process of playing the material, the video address of the next material to be played and the video tag in the hidden state can be associated, correspondingly, the next material to be played corresponding to the video address is placed in the video tag, and because the video tag is in the hidden state, the next material to be played can be subjected to silent rendering under the silent state which is not sensed by the user. Because the resources occupied by the video are often large, the time required for directly rendering the video is long, and the silent rendering is carried out on the next played material in the process of playing the material, so that the preloading of the next played material is realized, the fluency of the multimedia stream when the currently played material is switched to the video is improved, and the display effect is ensured.
In this embodiment of the present invention, if the currently played material is a picture and the next material to be played is a video, the silent rendering of the next material to be played includes:
and rendering the next material to be played in a silent mode according to the playing time length of the currently played material.
If the currently played material is a picture and the next material to be played is a video, the next material to be played can be rendered in a silent manner according to the playing duration of the currently played material. The silent rendering may be performed on the next material to be played in a time period during which the currently played material is played, for example, the currently played material is played in a time period a, and correspondingly, the silent rendering is performed on the next material to be played in the time period a. Because the resources occupied by the video are often large, the time required for directly rendering the video is long, and in the process of playing the currently played material, the silent rendering is performed on the next played material according to the playing time of the currently played material, so that the preloading of the next played material is realized, the fluency of the material in the multimedia stream when the video is switched from the picture is improved, and the display effect is ensured.
In this embodiment of the present invention, if the currently played material is a video and the next material to be played is a video, the silent rendering of the next material to be played includes:
and rendering the next material to be played in a silent mode according to the time length which is less than the playing time length of the next material to be played.
If the currently played material is a video and the next material to be played is a video, the next material to be played can be rendered in a silent manner according to the time length which is less than the playing time length of the next material to be played. For example, in the process of playing the currently played material, the next material to be played is loaded for only 500ms, so as to skip the flashing stage of the next material to be played, and ensure the playing effect of the next material to be played. And after 500ms of loading the material to be played next, interrupting the loading of the material to be played next. Because the time length of the silent rendering of the next material to be played is less than the playing time length of the next material to be played, the occupation of resources in the rendering process of the next material to be played is reduced, and the playing efficiency is improved.
In this embodiment of the present invention, if the next material to be played is a video, no matter whether the currently played material is a video or a picture, step S103: after the material is played, playing the next material to be played, including:
after the material is played, the video label is adjusted from the hidden state to the display state, and the material to be played next after silent rendering is played again.
After the currently played material is played, the video tag can be adjusted from the hidden state to the display state, accordingly, the sound of the next material to be played after silent rendering is opened, and the corresponding progress bar is dragged to the initial position, so that the next material to be played after silent rendering is played again.
In this embodiment of the present invention, after the next material to be played is played, the method further includes:
and releasing the association relation between the video address of the next material to be played and the video label in the display state, and adjusting the video label from the display state to the hidden state.
After the next material to be played is played, the association relationship between the video address of the next material to be played and the video tag in the display state can be released, and accordingly, the material content corresponding to the video address to be played in the next video tag can be emptied, so that the occupation of equipment resources is avoided. Besides, when the association relation is released, the mute can be kept, and the video label is adjusted from the display state to the hidden state. Therefore, the video tag adjusted to the hidden state is convenient for subsequent binding with other video addresses to control subsequent video playing.
It should be noted that, if the currently played material is a video and the next material to be played is also a video, the video tag associated with the video address of the currently played material is different from the video tag associated with the video address of the next material to be played, for example, one of the video tags is video1 and the other video tag is video 2. Therefore, even if two continuous materials to be played are videos, each material is associated with different video tags, so that the video playing of each material is respectively controlled, and the playing performance is improved.
In a second implementation manner, if the next material to be played is a picture, step S102: in the process of playing the material, preloading a material to be played next in the multimedia stream, including:
and in the process of playing the material, associating the picture address of the next material to be played with the picture tag in a hidden state, and rendering the next material to be played in a silent mode.
In the process of playing the material, whether the played material is a video or a picture, the picture address of the next material to be played and the picture tag in the hidden state can be associated, correspondingly, the next material to be played corresponding to the picture address is placed in the picture tag, and the picture tag is in the hidden state, so that in the process of playing the material, the next material to be played can be subjected to silent rendering in a state which is not sensed by a user, preloading of the next material to be played is realized, and therefore, the fluency of the multimedia stream when the current material to be played is switched to the picture is improved, and the display effect is guaranteed.
It should be noted that, if the currently played material is a picture and the next material to be played is also a picture, the picture tags associated with the picture addresses of the currently played material are different from the picture tags associated with the picture addresses of the next material to be played, for example, one of the picture tags is img1 and the other picture tag is img 2. Therefore, even if two continuous materials to be played are pictures, each material is associated with different picture labels, so that the respective control of playing the pictures of each material is realized, and the playing performance is improved.
In addition, because the resources occupied by the pictures are often small, even if the time required for direct rendering is often short, in the actual playing process, when a plurality of materials to be played continuously are all pictures, the picture addresses of the corresponding materials can be associated with the picture tags in the hidden state to realize the playing control of the corresponding materials, and even if the picture tags in the hidden state are associated with and occupied by other picture addresses, the previous picture address associated with the corresponding picture tag can be replaced by the picture address of the material to be played, so that the playing control of the corresponding material is realized.
In the embodiment of the present invention, in the second implementation manner, step S103: after the material is played, playing the next material to be played, including:
after the material is played, the picture label is adjusted from the hidden state to the display state, and the material to be played next after silent rendering is played.
After the materials are played, the picture labels can be adjusted from the hidden state to the display state, so that the next material to be played after the previous silent rendering can be played.
In the embodiment of the present invention, as shown in fig. 2, if the currently played material is a video and the material is the first material in the multimedia stream, in step S101: after determining the currently played material in the multimedia stream, the method further comprises:
s201: determining a thumbnail of the material and a thumbnail address of the thumbnail;
s202: associating the thumbnail address with a picture label in a hidden state, rendering the thumbnail, adjusting the picture label from the hidden state to a display state, and displaying the rendered thumbnail;
s203: in the process of displaying the thumbnail, associating the video address of the material with the video label in the hidden state, and rendering the material in a silent mode;
s204: and replaying the material subjected to silent rendering.
In the specific implementation process, the specific implementation process from step S201 to step S204 is as follows:
if the currently played material is a video and the material is the first material in the multimedia stream, that is, the currently played material is the first material to be played in the multimedia stream and the material is the video. After determining a material currently played in the multimedia stream, determining a thumbnail of the material and a thumbnail address of the thumbnail, where when the material is a video, the thumbnail of the material may be a first frame image in the video, or may be a key frame image in the video, which is not limited herein. And then, associating the thumbnail address with the picture label in the hidden state, rendering the thumbnail, adjusting the picture label from the hidden state to the display state, and displaying the rendered thumbnail. And then, in the process of displaying the thumbnail, associating the video address of the material with the video label in the hidden state, and rendering the material in a silent mode. In addition, in an initial state, when the first material in the multimedia stream in the related technology is a video, the video often carries a triangle symbol, and if the video is directly played, the use experience of a user is seriously influenced.
In the process of displaying the thumbnail, associating the video address of the material with the video tag in the hidden state, and accordingly, placing the material in the video tag, wherein the video tag is in the hidden state, so that the material can be silently rendered in the process of displaying the thumbnail, and the silently rendering of the material in the silent state can be controlled. That is to say, in the process of shielding by the thumbnail, the video material to be played is subjected to silent rendering, so that the video material to be played is preloaded. After hundreds of milliseconds, the picture tag is adjusted from the display state to the hidden state, and the video tag associated with the video address of the material is adjusted from the hidden state to the display state, accordingly, the sound of the video tag is turned on, the corresponding progress bar is restored to the initial position, and the video material subjected to silent rendering is replayed, so that the black screen phenomenon caused when the first video material in the multimedia stream is directly played in the initial state is avoided, and the playing effect of the video is ensured.
Next, when an advertisement is played, a page has two video tags including video1 and video2 and two picture tags including img1 and img2, where each tag may have two states of a hidden state and a displayed state, the currently played material is, for example, the first material in the multimedia stream, and fig. 3 is a schematic flow chart of a method for controlling playing of the corresponding material. Since the whole process has been described in detail in the foregoing, it is not described herein again.
It should be noted that the multimedia playing method described above may be applied to android mixed playing, and the webview calls the relevant playing component to play each material in the multimedia stream, or may be applied to android native playing, and directly calls the relevant playing component to play each material in the multimedia stream. In practical applications, the material in the multimedia stream can be played in a corresponding manner by combining with the preloading method mentioned in the embodiments of the present invention, which is not described in detail herein.
Based on the same inventive concept, as shown in fig. 4, an embodiment of the present invention further provides a multimedia playing apparatus, including:
the device comprises a determining unit 1, a playing unit and a playing control unit, wherein the determining unit is used for determining currently played materials in a multimedia stream, and the multimedia stream comprises a plurality of materials to be played which are sequentially arranged;
the preloading unit 2 is used for preloading a next material to be played in the multimedia stream in the process of playing the material;
and the playing unit 3 is used for playing the next material to be played after the material is played.
Since the principle of the multimedia playing apparatus for solving the problem is similar to the multimedia playing method, the implementation of the multimedia playing apparatus can refer to the implementation of the multimedia playing method, and repeated details are not repeated.
The multimedia playing device provided by the embodiment of the invention can be an advertisement pushing machine and can also be a roadside indicator, correspondingly, the multimedia stream can be an advertisement which needs to be pushed to a user by a corresponding device, and the multimedia playing device can also be any product or part with a multimedia playing function, such as a mobile phone, a tablet personal computer, a television, a notebook computer, a navigator and the like.
