Fig. 4 corresponds to an audio data flow diagram of the method of fig. 3. As shown in fig. 4, when the player plays audio, data is written to the ring buffer of the audioflexinger track by the AudioTrack example, and the duplicating thread in the audioflexinger writes data to the mixing thread MixerThread of the speaker and the mixing thread MixThread of the Remote _ Submix _ Out at the same time. Wherein, the data written to the loudspeaker MixerThread is output through the loudspeaker, and the data written to the Remote _ sub _ Out MixThread is written to the remotesub _ hal. Data of Remote _ Submix _ Out In RemoteSubmix hal is written to Remote _ Submix _ In, and then the screen recording application can record from Remote _ Submix _ In to the played audio through the AudioRecord instance.
Fig. 5 is a schematic flowchart illustrating a process of creating a two-way thread according to an embodiment of the present invention. The screen recording application records using AUDIO _ SOURCE _ REMOTE _ submit as a data SOURCE. In the prior art, at the time of recording, the output of audio data is switched from the speaker to Remote _ sub _ Out, thereby causing the speaker to be silent. Therefore, it is possible to modify the output of audio data such that when the Remote _ sub _ Out is connected, the output device is selected, the Remote _ sub _ Out and the speaker are simultaneously selected, and the dual audio thread is created to make the speaker have audio playback.

Fig. 6 is a schematic flow chart of screen recording volume processing according to an embodiment of the present invention. As shown in fig. 6, when DuplicatingThread executes prepatrack _ l, the volume of the current media stream is calculated and saved in the AudioMixer, and then mAudioMixer- > process () is called in the threadLoopMix of DuplicatingThread, at this time, the volume is applied to the data stream, and attenuated data is obtained. The attenuated data is then written to RemoteSubmix and mixhread of the loudspeaker, respectively, with the volume in both mixhreads set to MAX (1.0) by default. Therefore, the data is not subjected to volume processing. Finally, the data obtained by the RemoteSubmix and the loudspeaker are both attenuated data.
Fig. 7 is a schematic flow chart of another screen recording volume processing according to an embodiment of the present invention. As shown in fig. 7, when DuplicatingThread calls prepatrack _ l, the volume of the current media stream is calculated, the volume is stored in vol _ temp, the volume of the AudioMixer is set to MAX (1.0), and then maudiomomixer- > process () is called in the videomix of DuplicatingThread, at which time the volume is applied to the data stream, resulting in unattenuated data. The unattenuated data is then written to RemoteSubmix and mixhread of the loudspeaker, respectively, the volume in this RemoteSubmix mixMixthread being set to MAX (1.0) by default, so that no further volume processing is performed on the data. At this time, data obtained by RemoteSubmix is data which is not attenuated, and in mixhread of the speaker, vol _ temp which has been stored before is set in the AudioMixer, and then attenuated data is obtained. Therefore, original unattenuated data can be obtained by playing the recording without changing along with the adjustment of the volume, and the sound of the loudspeaker can also change along with the adjustment of the volume.
In the method for processing screen recording volume shown in fig. 6, the volume of the audio data played by the speaker and the volume of the audio data in the screen recording video file are both the current playing volume set by the user. The current playing volume set by the user is often smaller than the maximum volume of the player, so that the audio data in the screen recording video file is attenuated. In the method for processing screen recording volume shown in fig. 7, the screen recording thread adopts volume maximization recording, so that the amplitude of the recorded audio is not attenuated compared with the original audio amplitude, the speaker thread adopts current playing volume output, the playing of the speaker is not affected when the screen recording is performed, and the recorded audio is consistent with the played audio. The volume of audio data played by the speaker in fig. 7 is the current play volume set by the user, and the volume of audio data in the screen-recorded video file is the unattenuated audio data. Therefore, compared with the method for processing the screen recording volume shown in fig. 6, the method for processing the screen recording volume shown in fig. 7 can record the audio content currently being played completely and losslessly while recording the screen, and does not affect the current playing.
According to the method, the audio data are respectively written into the input end and the loudspeaker of the remote audio mixing equipment through the two-way thread. In the screen recording process, the audio file is written into the video file of the screen recording, and meanwhile, the corresponding audio file can be played by the loudspeaker, so that the use feeling of a user in the screen recording process is improved.
