Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
In the description that follows, embodiments of the invention are described with reference to steps and symbols of operations performed by one or more computers, unless otherwise indicated. It will thus be appreciated that those steps and operations, which are referred to herein several times as being computer-executed, include being manipulated by a computer processing unit in the form of electronic signals representing data in a structured form. This manipulation transforms the data or maintains it at locations in the computer's memory system, which may reconfigure or otherwise alter the computer's operation in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific details shown, since one skilled in the art will recognize that various steps and operations described below may be implemented in hardware.
Referring to fig. 1, fig. 1 is a scene diagram of a play control method according to an embodiment of the present invention. The playing control method is mainly applied to terminals such as mobile phones and PADs. For example, taking a mobile phone as an example, when a user plays a television play with the mobile phone, the user suddenly needs to watch an XX map, so as to facilitate traveling or just to view a certain place mentioned in the television play, so that the playing application is switched from foreground running to background running, and the XX map is opened, and during switching, the playing of the video data of the video file is paused, and the audio data of the video file is played. When the application is switched back to play, the video data and the audio data are played synchronously.
Referring to fig. 2, fig. 2 is a flowchart of a play control method according to an embodiment of the present invention, in which the play control method includes the following steps:
s101, in the process of playing the audio-video file, when the situation that the playing application is switched from foreground operation to background operation is detected, the playing of the video data of the audio-video file is paused, and the playing of the audio data of the audio-video file is continued.
The playing application can be a Tencent player, a Youku player, a potato player and the like, and can be played not only online but also locally.
The video file can be a common television play, a movie, a comprehensive program, a sports event and the like. The video and audio file comprises video data and audio data. The video data provides image information for users during playing, the audio data provides audio information during playing, and the video data and the audio data are played synchronously without the dislocation of sound and images.
In this step, when it is detected that the playback application is switched from foreground operation to background operation, for example, when the user plays a tv play with a mobile phone's youth player, the playback application continues to play audio information and stops playing video information when the user needs to switch to screen to return information, write a novel, watch a web page, and so on. That is, after the screen is switched, the user can judge the playing progress according to the played audio data, and after the playing of the video data is paused, the utilization rate of a CPU (Central processing Unit) can be reduced, and the power consumption is reduced. Moreover, the user can cut away when encountering a picture which is not wanted to be seen, and judge whether the picture is played completely according to the played audio data, so that the watching experience of the user is improved, and the intelligent control system of playing is improved.
In the scheme, the scenes need to be learned, and the audio data can still be played and the video data can be paused after the switching only in the preset scenes. For example, learning is performed on a telephone scene, a music playing scene, and the like, and when a scene for playing an audio/video file is switched to these scenes, a playing application running in the background directly suspends the playing of video data and audio data. In the scenes of watching a novel scene, viewing a short message scene, using an application irrelevant to audio and the like, the audio data can still be played after switching, and the video data is paused to be played.
S102, when it is detected that the playing application is switched back to the foreground operation from the background operation, a first playing progress of the audio data is obtained.
When the playing application is switched back to the foreground for operation, the audio data and the video data need to be played synchronously, and because the playing application is in the background operation period, the audio data is played and the video data is paused, the progress of the audio data and the video data is not synchronized, and when the audio data and the video data are played simultaneously again, the target playing progress of the video data needs to be obtained according to the first playing progress of the audio playing data.
S103, acquiring a target playing progress corresponding to the video data according to the first playing progress.
In the step, in a specific application process, the target playing progress is obtained according to the time axes of the audio data and the video data. For example, when the first progress shows that the time axis of the audio data runs to a position of 10 minutes and 25 seconds, the running position of the playing time axis of the video data also needs to be 10 minutes and 25 seconds to synchronize the audio data with the video data. Therefore, the target playing progress of the video data is obtained in a time axis synchronization mode.
And S104, synchronously playing the video data and the audio data according to the target playing progress and the first playing progress.
In this step, according to the current position of the time axis of the video data acquired in step S103, the video data is jumped from the pause position to the current position to start playing, so that the playing of the video data and the playing of the audio data are synchronized, and the normal playing of the video and audio file is realized.
As can be seen from the above, in the process of playing an audio-visual file by a playing application, when it is detected that the playing application is switched from foreground operation to background operation, the embodiment of the present invention keeps the audio data of the audio-visual file being continuously played and suspends the playing of the video data of the audio-visual file; when the fact that the playing application is switched back to the foreground running from the background running is detected, acquiring a current first playing progress of the audio data; acquiring a target playing progress of the video data according to the first playing progress of the audio data; playing the video data according to the target playing progress so that the video data and the audio data are played synchronously; therefore, the playing control of the audio and video files is realized, and the method has the advantages of reducing power consumption and improving the playing intelligence.
Referring to fig. 3, fig. 3 is a flowchart of a play control method according to an embodiment of the present invention, in which the play control method includes the following steps:
s201, in the process of playing the audio and video file, when the situation that the playing application is switched from foreground operation to background operation is detected, the playing of the video data of the audio and video file is paused, and the playing of the audio data of the audio and video file is continued.
The playing application can be a Tencent player, a Youku player, a potato player and the like, and can be played not only online but also locally.
The video file can be a common television play, a movie, a comprehensive program, a sports event and the like. The video and audio file comprises video data and audio data. The video data provides image information for users during playing, the audio data provides audio information during playing, and the video data and the audio data are played synchronously without the dislocation of sound and images.
In this step, when it is detected that the playback application is switched from foreground operation to background operation, for example, when the user plays a tv play with a mobile phone's youth player, the playback application continues to play audio information and stops playing video information when the user needs to switch to screen to return information, write novels, and so on. That is, after the screen is switched, the user can judge the playing progress according to the played audio data, and after the playing of the video data is paused, the utilization rate of a CPU (Central processing Unit) can be reduced, and the power consumption is reduced.
In some embodiments, this step S201 includes:
and S2011, monitoring running states of the playing application in real time, wherein the running states comprise foreground running and background running.
S2022, when it is monitored that the playing application is switched from foreground operation to background operation, the audio data of the audio-video file is kept to be continuously played and the video data of the audio-video file is paused to be played.
S202, when the fact that the playing application is switched back to the foreground running from the background running is detected, a current first playing progress of the audio data is obtained, and the playing of the audio data is paused.
When the playing application is switched back to the foreground for operation, the audio data and the video data need to be played synchronously, and because the playing application is in the background operation period, the audio data is played and the video data is paused, the progress of the audio data and the video data is not synchronized, and when the audio data and the video data are played simultaneously again, the target playing progress of the video data needs to be obtained according to the first playing progress of the audio playing data. Moreover, when switching back to the foreground, there may be a delay in calculating the target playing progress of the video data, so that the playing of the audio data is suspended first.
S203, obtaining a target playing progress corresponding to the video data according to the first playing progress.
In the step, in a specific application process, the target playing progress is obtained according to the time axes of the audio data and the video data. For example, when the first progress shows that the time axis of the audio data runs to a position of 10 minutes and 25 seconds, the running position of the playing time axis of the video data also needs to be 10 minutes and 25 seconds to synchronize the audio data with the video data. Therefore, the target playing progress of the video data is obtained in a time axis synchronization mode.
In some embodiments, this step S203 includes:
s2031, a first time point corresponding to the first playing progress on a first time axis of the audio data is obtained.
The audio data and the video data are played with a time axis, and the start time of the time axis is the same because the audio data and the video data are played synchronously at the beginning. Each first playing progress corresponds to a first time point on the first time axis.
S2032, a second time point on a second time axis of the video data is obtained according to the first time point, and the first time point is the same as the second time point.
In order to synchronously play the audio data and the video data, a second time point corresponding to the target playing progress on a second time axis must be obtained, and in this scenario, the time corresponding to the second time point is the same as the time corresponding to the first time point.
S2033, obtaining the target playing progress of the video data according to the second time point.
After the second time point on the second time axis is obtained, the target playing progress of the video data to be played synchronously with the audio data can be obtained.
S204, playing the video data according to the target playing progress, and playing the audio data according to the first playing progress so that the video data and the audio data are played synchronously.
In this step, the playing progress of the video data is jumped from the pause position to the currently located second time point to start playing according to the second time point obtained in step S203, and the audio data is started to be played according to the first playing progress while the video data is started to be played, so that the playing of the video data and the playing of the audio data are synchronized, and the normal playing of the audio and video file is realized.
In some embodiments, between step S201 and step S202, the following steps may be further included:
s500, when the fact that the playing application is switched from foreground running to background running is detected, the duration of the background running exceeds the preset duration, the playing of the audio data is paused. For example, the preset time period may be set to 5 minutes. When the preset time length is exceeded, the user does not switch the playing application from the background operation to the foreground operation, which indicates that the user does not want to watch the audio and video file when the user is occupied, and therefore, the audio data is directly paused to be played.
In some embodiments, between step S201 and step S202, the following steps may be further included:
s600, when it is detected that the playing application is switched from foreground operation to background operation, and the duration of the background operation exceeds a preset duration, the volume of playing the audio data is reduced. For example, the preset time period may be set to 5 minutes. When the preset time length is exceeded, the user does not switch the playing application from the background operation to the foreground operation, which indicates that the user does not want to watch the audio-video file during occupation or does not have space during occupation, and therefore, the audio data playing volume is gradually reduced.
As can be seen from the above, in the process of playing an audio-visual file by a playing application, when it is detected that the playing application is switched from foreground operation to background operation, the embodiment of the present invention keeps the audio data of the audio-visual file being continuously played and suspends the playing of the video data of the audio-visual file; when the fact that the playing application is switched back to the foreground running from the background running is detected, acquiring a current first playing progress of the audio data; acquiring a target playing progress of the video data according to the first playing progress of the audio data; playing the video data according to the target playing progress so that the video data and the audio data are played synchronously; therefore, the playing control of the video and audio file is realized.
