I’m going to use the Java provided command line class ProcessBuilder.start() to execute the ffmpege command under Windows to do the push. But when I execute without any errors, I get stuck reading the InputStream message

    public static void main(String[] args) {
        try {
            ProcessBuilder builder = new ProcessBuilder("cmd.exe","-C","ffmpeg -re -stream_loop -1 -i D:\tmp\video\ligelHigh1\1.mp4 -c copy -f rtsp rtsp://127.0.0.1:8554/stream");
            Process exec = builder.start();
            StringBuilder output = new StringBuilder();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(exec.getInputStream()));
            String line;
            System.out.println("get info");
            while ((line = bufferedReader.readLine()) != null) {
                System.out.println(line);
                output.append(line).append("n");
            }
            BufferedReader errorBufferRead = new BufferedReader(new InputStreamReader(exec.getErrorStream()));
            String eline;
            System.out.println("get error info");
            while ((eline = errorBufferRead.readLine()) != null) {
                output.append(eline).append("n");
            }
            System.out.println("waiting.......");
            int wait = exec.waitFor();
            System.out.println("process execute end.");
            if(wait == 0) {
                System.out.println("Success");
                System.out.println(output);
            }else {
                System.out.println("Failure");
                System.out.println(output);
            }
        }catch (IOException | InterruptedException e) {
            throw new RuntimeException(e);
        }
    }

I monitored the JVM process using jconsole and found some information.
