In this embodiment, considering that all the sounds to be played by the specific application of screen projection itself are the method (write) of writing audio through the above audio track (AudioTrack), the present embodiment uses the specific application of screen projection as the basis for intercepting the method (write) of writing audio.
In this embodiment, if it is detected that the process of the specific application of the screen projection is a widget process, the audio data transmitted by the process is intercepted. Thereby, the audio data incoming by the above process is not transferred to the subsequent audio composition service (AudioFlinger). It can be understood that if the audio data incoming from the above process is transferred to the subsequent audio synthesis service (AudioFlinger), the audio data incoming from the process will be output to the external of the handset itself, which may cause audio interference.
In this embodiment, the audio data transmitted by the process is transmitted to the established screen projection channel as an audio buffer (buffer), specifically, data transmission may be performed in a socket (socket) manner, so that the audio data transmitted by the process can reach the screen projection end establishing the screen projection connection with the screen projection end.
In the above embodiment, the sound of the small window is intercepted and sent to the screen projection end, and it can be understood that if the small window application only has one audio track (AudioTrack), that is, one audio track (AudioTrack) is a fixed frequency and a fixed channel, at this time, the audio playing can be realized by directly transmitting data to the screen projection computer end. However, considering more specific applications of screen projection, there is not only one audio track, such as game programs related to peaceful elite, but also a game background audio track and a microphone speaking audio track, and the two audio tracks have completely different frequencies and channel numbers. Therefore, the embodiment distinguishes the receiving end of the audio track, that is, distinguishes the audio track to transmit and receive, then performs audio track synthesis and resampling on the received data, and finally transmits the processed data to the screen projection end to play.
It can be seen that, in this embodiment, a process related to audio track tracking (AudioTrack) is skillfully used, so as to distinguish application sources of sound, and then, in a synthesis stage of a mobile phone audio, screen-projected application sound and non-screen-projected application sound are separately synthesized and separately output, so that an audio isolation effect unified with picture isolation in a screen-projected mode is achieved.
The method has the advantages that the audio data belonging to the screen projecting window process is intercepted in the audio writing process of the projected end; detecting a track type of the audio data; if the audio data is of a single audio track type of a game audio track or a microphone audio track, transmitting the audio data to a screen projection end corresponding to the projected end for playing; and if the audio data are of multiple audio track types of the game audio track and the microphone audio track, synthesizing and resampling the game audio track and the microphone audio track, and transmitting the processed audio data to the screen projection end for playing.
