Answer 1

This will print the video FPS:

ffprobe -v error -select_streams v -of default=noprint_wrappers=1:nokey=1 -show_entries stream=r_frame_rate file.mp4

Answer 2

I found calculate fps in another method that is..

String query = "ffmpeg -i foo.avi 2>&1 | sed -n 's/.*, \\(.*\\) fp.*/\\1/p' > fps.txt";
    String[] command = {"gnome-terminal", "-x", "/bin/sh", "-c", query};
    Process process = Runtime.getRuntime().exec(command);
    process.waitFor();
    Thread.sleep(2000);
    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("fps.txt")));
        output = br.readLine();
    } catch (IOException ioe) {
        ioe.printStackTrace();
    }

Anyway thanks friends.
