java ffmpeg 麦克风采集

Java中可以使用FFmpeg库进行麦克风采集。下面是一个使用Java调用FFmpeg进行麦克风采集的示例代码：

import java.io.IOException;

public class FFmpegMicrophoneCapture {
    public static void main(String[] args) {
        String ffmpegPath = "path/to/ffmpeg.exe";
        String outputFilename = "output.wav";

        try {
            Process process = new ProcessBuilder(ffmpegPath, "-f", "dshow", "-i", "audio=\"麦克风(High Definition Audio 设备)\"", "-acodec", "pcm_s16le", outputFilename)
                    .redirectErrorStream(true)
                    .start();

            // 等待FFmpeg进程结束
            process.waitFor();

            System.out.println("麦克风采集完成！");
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
