Embodiment 1

[0028] See figure 2 , which is a flowchart of an embodiment of the multi-audio selection playback method in the embodiment of the present application, the method may include the following steps:

[0029] Step 201: When receiving audio data belonging to different audio sources at the same time, determine the audio data corresponding to the most recently activated audio source as the target audio data according to the respective activation sequences of the different audio sources.

[0030] Step 202: output the target audio data, and discard other audio data except the target audio data in the received audio data.

[0031] Step 201 and step 202 are described as follows:

[0032] In the embodiment of this application, take the application of the multi-audio selection playback method provided by this application in the application scenario of audio playback based on the GStreamer framework as an example:

[0033] Specifically, with the audio playback pipeline in the prior art, f...

Embodiment 2

[0044] See Figure 4 , is a flow chart of another embodiment of the multi-audio selection playback method in the embodiment of the present application. The method is described above figure 2 On the basis of the method shown, it focuses on how the audio selection component determines the audio data corresponding to the most recently activated audio source as the target audio data according to the respective activation sequences of different audio sources, which may include the following steps:

[0045] Step 401: Obtain the respective play sequence numbers of different audio sources, the play sequence numbers are set according to the start sequence of the audio sources.

[0046] Step 402: Determine the audio data corresponding to the audio source with the largest playback sequence number as the target audio data.

[0047] Step 401 and step 402 are described in detail as follows:

[0048] First of all, it needs to be explained that, in the embodiment of the present application...

Abstract

The application provides a selection playing method and device of multiple pieces of audio frequency. The method includes: when audio-frequency data belonging to different audio-frequency sources aresimultaneously received, determining, according to a respective starting order of the different audio-frequency sources, that the audio-frequency data corresponding to the most recently stated audio-frequency source are target audio-frequency data; and outputting the target audio-frequency data, and discarding the other audio-frequency data which are in the received audio-frequency data and otherthan the target audio-frequency data. By applying the method, only playing the audio frequency of one of the multiple audio-frequency sources at the same time when the multiple audio-frequency sourcesare simultaneously started can be realized, and thus problems that in the prior art, the audio frequency of the multiple audio-frequency sources are mixed together to be played, definition of the audio frequency is severely impacted, and unsatisfactory user experience is caused are effectively avoided.

Description

technical field [0001] The present application relates to the field of multimedia technology, in particular to a method and device for selecting and playing multiple audios. Background technique [0002] With the popularity of the Internet and multimedia playback equipment, user needs are becoming more and more diverse. In an application scenario, when a user uses a multimedia playback device, such as a smart TV to watch TV programs, he may also want to obtain other audio, such as playing his favorite music, or enabling a voice assistant, etc., while the user And don't want to pause or quit watching TV. [0003] Then, in the prior art, the smart TV will play the audio of the TV program and the other audio at the same time, that is to say, when multiple audio sources are started at the same time, the multimedia playback device will mix the audio data of the multiple audio sources If they are played together, the clarity of the audio will be seriously affected, resulting in ...
