Question

我正在研究ffmpeg视频比较。我从java调用ffmpeg视频比较命令。执行命令后。比较过程停止了。如果我杀死了javaw.exe，则命令resume和working和result文件被创建。我使用以下代码执行命令：

String command2CompareVideos = "D:\\bin\\ffmpeg -y -i D:\\postVideo_16.mp4 -i D:\\postVideo_16.mp4 -filter_complex \"[1:v]format=yuva444p,lut=c3=128,negate[video2withAlpha],[0:v][video2withAlpha]overlay[out]\" -map [out] D:\\ResultVideo.mp4"

    String[] processCommand = { "cmd", "/c","CALL",  command2CompareVideos};
    Process imgComProcess = Runtime.getRuntime().exec(processCommand);  
    imgComProcess.waitFor();
    BufferedReader ouPiutReader = new BufferedReader(new InputStreamReader(imgComProcess.getInputStream()));
                String outPut = ouPiutReader.readLine();
                while(outPut != null){
                    outPut = ouPiutReader.readLine();
                    System.out.println("Output: "+outPut);
                }
