  • FFMPEG command on Android Jave Process does not fully execute

    8 novembre 2014, par user2491598

    The issue I am having is very strange. I have an FFMPEG executable binary library installed on my Android and I am trying to execute this command

    ffmpeg -loop 1 -i /storage/emulated/0/image.jpg -i /storage/emulated/0/input.mov -filter_complex '[0:v][1:v] overlay' -shortest /storage/emulated/0/output.mp4

    and my JAVA code looks like

    try {
    
            Runtime.getRuntime().exec("chmod 700 " + mFfmpegPath);
    
            cmd.add(mFfmpegPath);
    
            cmd.add("-loop");
    
            cmd.add("1");
    
            cmd.add("-i");
    
            cmd.add("/storage/emulated/0/image.jpg");
    
            cmd.add("-i");
    
            cmd.add("/storage/emulated/0/pizza.mov");
    
            cmd.add("-filter_complex");
    
            cmd.add("'[0:v][1:v] overlay'");
    
            cmd.add("-shortest");
    
            cmd.add("-vcodec");
    
            cmd.add("-libx264");
    
            cmd.add("-strict");
    
            cmd.add("experimental");
    
            cmd.add("/storage/emulated/0/output22.mp4");
    

    
            final ProcessBuilder pb = new ProcessBuilder(cmd);
    
            pb.redirectErrorStream();
    
            final Process p = pb.start();
    
            Log.i("FFMPEG","stdError= " + getSTD(p.getErrorStream()));
    
            p.waitFor();
    
            return run;
    
        } catch (IOException e1) {
    
            // TODO Auto-generated catch block
    
            e1.printStackTrace();
    
        } catch (InterruptedException e) {
    
            // TODO Auto-generated catch block
    
            e.printStackTrace();
    
        }

    For some reason I the execution does not fully finish and it stops. It does not even create an output file in my Android storage. Here is the log file from the process stream

  • Making progress bar with FFmpeg duration value

    11 novembre 2014, par user2978381

    I am mainly a back-end developer. I have rarely used javascript. But for real time update now I have to use javascript, ajax, jquery or something like that.

    My php script outputs this value "100%" at the end of the conversion.

     echo "Progress: " . $progress . "%";

    The $progress variable actually holds numeric data like 10 and I want to use this value for making progress bar. The value of the $progress variable changes every second and I need to capture this value.

    So if I want to implement this value in the following html file what will I do actually ?

    <code class="echappe-js">&lt;script src=&quot;//code.jquery.com/jquery-1.10.2.js&quot;&gt;&lt;/script&gt;
    

    &lt;script src=&quot;//code.jquery.com/ui/1.11.2/jquery-ui.js&quot;&gt;&lt;/script&gt;
    

    &lt;script&gt;<br />
    
$(function() {<br />
    
  var progressbar = $( &quot;#progressbar&quot; ),<br />
    
    progressLabel = $( &quot;.progress-label&quot; );<br />
    
<br />
    
  progressbar.progressbar({<br />
    
    value: false,<br />
    
    change: function() {<br />
    
      progressLabel.text( progressbar.progressbar( &quot;value&quot; ) + &quot;%&quot; );<br />
    
    },<br />
    
    complete: function() {<br />
    
      progressLabel.text( &quot;Complete!&quot; );<br />
    
    }<br />
    
  });<br />
    
<br />
    
  function progress() {<br />
    
    var val = progressbar.progressbar( &quot;value&quot; ) || 0;<br />
    
<br />
    
    progressbar.progressbar( &quot;value&quot;, val + 2 );<br />
    
<br />
    
    if ( val &lt; 99 ) {<br />
    
      setTimeout( progress, 80 );<br />
    
    }<br />
    
  }<br />
    
<br />
    
  setTimeout( progress, 2000 );<br />
    
});<br />
    
&lt;/script&gt;
