FFMPEG is timing out and getting killed before completing process

I have a script that takes an mp4 file and splits it into another mp4 file. It basically takes a section like 00:22:38 to 00:23:16 and creates a new video from that time segment. The problem is that for larger files the process stops and gets killed before finishing. ffmpeg -i "/uploads/files/[login to view URL]" -ss 00:22:38 -t 00:23:16 -async 1 "/uploads/files/[login to view URL]" problem is [login to view URL]() does not wait and the process is killed without any errors in the log file. the process actually starts but killed before completion. This is the script that is called. @RequestMapping(value = "/videotrim", method = [login to view URL]) public void trimVideo(@RequestParam Long id, @RequestParam("start-time") Integer startTime, @RequestParam("end-time") Integer endTime) { [login to view URL](getClass().getName()).log([login to view URL], "called"); Document one = [login to view URL](id); [login to view URL](getClass().getName()).log([login to view URL], "called" + [login to view URL]); String inputFile = [login to view URL]("%20"," "); final String movieFile = "/uploads" + inputFile; final String resultFile = "/uploads/files/" + id + "-" + startTime + "-" + endTime + ".mp4"; //ffmpeg -i [login to view URL] -ss 00:00:03 -t 00:00:08 -async 1 [login to view URL] Time start = new Time(startTime * 1000); Time end = new Time(endTime * 1000); final String startTimeSec = [login to view URL](); final String endTimeSec = [login to view URL](); Runnable runnable = new Runnable() { public void run() { try { File file = new File(resultFile); if (![login to view URL]()) { final String command = "ffmpeg -i \"" + movieFile + "\" -ss " + startTimeSec + " -t " + endTimeSec + " -async 1 \"" + resultFile + "\""; [login to view URL](getClass().getName()).log([login to view URL], "running: " + command); ProcessBuilder pb = new ProcessBuilder("ffmpeg", "-i", movieFile, "-ss", startTimeSec, "-t", endTimeSec, "-async", "1", resultFile); pb = [login to view URL](true); // equivalent of 2>&1 Process p = [login to view URL](); [login to view URL](); file = new File(resultFile); [login to view URL](true,false); } else { [login to view URL](true,false); } } catch (Throwable e) { [login to view URL](getClass().getName()).log([login to view URL], "error while trim video", e); [login to view URL](); } } }; new Thread(runnable).start(); }
