In an embodiment of the application, when a flag character of a playing flag bit is TRUE, it indicates that an audio/video to be played is to be played; and when the flag character of the playing flag bit is FALSE, the audio and video to be played is not shown.
The application also claims an audio and video playing system based on time scheduling, comprising:
the first setting module is used for setting a playing flag bit;
the second setting module is used for setting the playing time;
and the playing module is used for playing the audio and video according to the playing zone bit and the playing time.
For example, the playback flow is as follows:
1.1 audio playing flag bit: audio _ play _ start, when the value is TRUE, it represents that there is audio to play, and when it is FALSE, it represents that the current audio play is stopped.
1.2 audio playing time: the play _ time, when 0, represents that the current audio only needs to be played once, and when not 0, for example, this value is 30, represents that the current audio needs to be played for 30S.
1.3 Audio Play host service: the service detects the value of audio _ play _ start, if TRUE, it indicates that there is audio to be played, and simultaneously obtains the audio file and play _ time that need to be played currently, where play _ time is 0, and only plays once, but not 0, and then plays in a loop; if it is FALSE, it indicates that the current playing task needs to be stopped.
1.4 Play time control service: the service detects the values of audio _ play _ start and play _ time as in the service of 1.3, and the service will execute when the audio _ play _ start is TRUE and the play _ time is not 0. For example, audio _ play _ start is TRUE, path _ time is 30S, the service just starts to record the current time and the time of audio playing end +30S, and then always detects whether the current time exceeds the audio playing time, if so, the audio _ play _ start is FALSE, and after detecting that the value is FALSE, the service of 1.3 stops the current playing task.
2. For better control of audio playback, two functions are also implemented:
2.1Audio Play Enable: and an audio _ run, which sets audio _ play _ start to TRUE, and sets the current play time, and sets the currently played audio.
2.2Audio Play stop: audio _ stop, which sets audio _ play _ start to FALSE
And will set the current playing time to 0.
3. With the above components in mind, and by way of example, the alert audio is currently required to be played for 30 seconds, and when half of the alert audio is required to be played, the disarm audio is then stopped.
3.1 first the 1.3 audio playback main service and the 1.4 playback time control service are running in the background all the time.
3.2 execute 2.1audio _ run, set audio _ play _ start to TRUE, play _ time to 30S, current audio to warning.
3.3 the service of 1.3 and 1.4 above would get these settings, 1.3 would loop through the current audio until audio _ play _ start is FALSE, and then exit.
3.4 the Play time control service will detect whether the current time exceeds the audio play time, if yes, audio _ play _ start is FALSE, and at the same time the audio play main service detects this value and stops playing.
3.5 when half of the warning sound is played, we want to play the disc, and will first execute 2.2audio _ stop, stop the current audio playing, and play the disc after calling audio _ run.
The above embodiments are examples of playing audio, but not limited thereto. Those skilled in the art can change the type of the playing file, such as video file, etc., according to the actual requirement, and all fall within the scope of the claimed application.
Compared with the prior art, the method has the following beneficial effects:
1. the method is suitable for all Internet of things equipment with an audio playing function, has portability, and is suitable for platforms with different chip architectures.
2. The current audio can be played flexibly according to the set time.
3. The currently played audio can be switched at will, and the currently played task can be stopped at any time.
In addition, in the above embodiment, when the playing time n is 30, the corresponding time is 30 seconds. This is because the scenes that need to be played in the above-described embodiment are shorter for the audio to be played. However, the present invention is not limited thereto. The time unit corresponding to n, such as minutes, hours, even days, months or years, etc., can be changed by those skilled in the art according to actual needs, and all fall within the scope of the present application.
