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.

i'm trying let user reorder elements in scrollview list long-pressing on 1 of elements. we're trying let user use long press pick element of scrollview list, , put element somewhere else in list. have working using animated view, issue it's difficult integrate scrolling , swipe-to-delete animated view. we're hoping add "pick , reorder" scrollview. is there preferred method accomplishing this? touchablewithoutfeedback has onlongpress method, can implement this: _onlongpress() { // perform sort }, <touchablewithoutfeedback onlongpress={ () => this._onlongpress() }> <text>click , hold call onlongpress</text> </touchablewithoutfeedback> as far sorting, can use type of library such lodash or underscore, plus there ways sort using vanilla javascript. check out this thread. i've set basic project using sort function on listview here . https://rnplay.org/apps/mpbktg 'use strict'; var react = requ...
