video - What is wrong part in my Android code with ffmpeg? -

-

i want mixed video.(image + video) total duration of original video 180 sec. want put image front of video. so, made code in android studio. can not toast. wrong ? how check end of process?

... path = "libray folder"; ...

    private class processvideo extends asynctask<void, integer, void> {             @override             protected void doinbackground(void... params) {                  process ffmpegprocess = null;                  try {           // initialize command process video               // library video process library.                     string[] command ={path,"-i", input, "-r", "1", "-q:v", "2", "-f", "image", input};                       ffmpegprocess = new processbuilder(ffmpegcommand).redirecterrorstream(true).start();                      outputstream ffmpegoutstream = ffmpegprocess.getoutputstream();                     bufferedreader reader = new bufferedreader(new inputstreamreader(ffmpegprocess.getinputstream()));                      string line;                      log.v(thistag,"***starting ffmpeg***");                     while ((line = reader.readline()) != null)                     { // in progress                          log.v(thistag,"***"+line+"***");                     } // finish process                     log.v(thistag,"***ending ffmpeg***");                     videoprocessfinishflag = true;                  } catch (ioexception e) {                     e.printstacktrace();                 }                  if (ffmpegprocess != null) {                     ffmpegprocess.destroy();                 }                 return null;             }              protected void onpostexecute(void... result) { // show result                toast toast = toast.maketext(videoeditoractivity.this, "done processing video", toast.length_long);                 toast.show();             }         }

you missed parameters. try : string[] command ={path,"-y","-i", input,"-strict","experimental", "-r", "1", "-q:v", "2", "-f", "image", input}; above command there 2 "input", different each other. first parameter : video path second parameter : image file path right? command take few long times process video, think. thank commitment.
