启用屏幕录制权限:应用需要请求RECORD_AUDIO和CAPTURE_AUDIO_OUTPUT权限,以及CAPTURE_VIDEO_OUTPUT和CAPTURE_SECURE_VIDEO_OUTPUT(如果捕获安全内容)。 使用MediaProjectionManager:创建一个MediaProjection会话,并引导用户通过系统UI授权屏幕录制。 捕获音频:在录制屏幕时,音频也会同时被捕获。但是,这通常只适用于用户当前正在操...

这里需要实现OnDataCaptureListener的两个接口,其中onWaveFormDataCapture(Visualizer visualizer, byte[] waveform, int samplingRate) 中的waveform即为所截获的音频输出流,对其执行想要的操作即可。 关键代码: mVisualizer =newVisualizer(0);//get output audio streammVisualizer.setEnabled(false); ...
