• Can't obtain thumbnail with ffmpeg codeigniter

  2 avril 2015, par DMBorges

  I have used the following tutorial ( https://www.youtube.com/watch?v=qT4hN5o57hI) to try to obtain a thumbnail from a uploaded video using codeigniter as a framework. As I am new to all this I don’t understand if at the end of supposedly uploading my video the code failed to create a thumbnail, if my created thumbnail is somewhere lost in my computer of by some settings reasons ffmpeg is not working.

  Where does my $imageFile goes to ?

  Here is my code.

  MY VIEW

  <div>
  
  
  
              &lt;?php echo form_open_multipart('gallery/save/'); ?>
  
                  <table class="table">
  
                      <tr>
  
                          <td>Video</td>
  
                          <td>&lt;?php echo form_upload('pic'); ?></td>
  
                      </tr>
  
                      <tr>
  
                          <td>Descrição</td>
  
                          <td>&lt;?php echo form_input('description'); ?></td>
  
                      </tr>
  
                      <tr>
  
                          <td></td>
  
                          <td>&lt;?php echo form_submit('upload', 'Guardar', 'class="btn btn-primary"'); ?></td>

• Official Debian Package for Piwik now available

  15 avril 2014, par Matthieu Aubry — Community, Meta

  We are excited to announce the release of Piwik package for Debian based linux distributions !

  There are several ways to use Piwik :
  
   Download and upload to your server
  
   or use 1-click Piwik installers
  
   or use Microsoft web app gallery
  
   or buy Piwik Cloud
  
   or as of today, you may get Piwik using our Debian package

  What are the benefits of using Debian package over direct download ?

  For some system administrators, using Debian package is an easier alternative than directly downloading the code. It allows sysadmins to deploy Piwik within seconds using “apt-get install piwik -V”.

  How do I install Piwik using official debian package ?

  The package supports Apache and Nginx web servers. Read the documentation at debian.piwik.org.

  Do I have to use the Debian Package on my debian system ?

  No, you may still want to use Piwik using the direct download approach. You can keep Piwik upgraded quite easily using the popular 1-click automatic update.

  How do I report a bug or feedback ?

  Create a ticket on the Github project Issues page.

  Will the debian repository be maintained in the future ?

  Yes, Aurélien Requiem (github) along with the Piwik team are committed to maintain the Debian Piwik repository in the future.

  Thank you to Aurélien for his great work on preparing, testing, and maintaining the Debian repository for Piwik.

• Issue in concatenating two video files using FFMPEG

  12 mai 2014, par intrepidkarthi

  I am trying to concatenate two mp4 files taken from gallery. I am getting issue with process execution failure. I have added the code and the error log. Using the ffmpeg library taken from guardian project.

  I am running this in Samsung Galaxy S3 device.

  The error is thrown in this particular line.

  ProcessBuilder pb = new ProcessBuilder(cmds);
  
  pb.directory(fileExec);
  
  Process process = pb.start();  

  When I replace the last line above with this,

  Process process = Runtime.getRuntime().exec("chmod 777 "+cmds.toArray(new String[cmds.size()]));

  It works with out the exception as shown below. But the output doesn’t seem to come.

  File concatenation Code :

      File fileVideoOutput = new File(getApplicationContext()
  
              .getExternalFilesDir("test") + "hello.mp4");
  
      fileVideoOutput.delete();
  
  
  
      File fileTmp = getApplicationContext().getCacheDir();
  
      File fileAppRoot = new File(getApplicationContext()
  
              .getApplicationInfo().dataDir);
  
  
  
      try {
  
          FfmpegController fc = new FfmpegController(fileTmp, fileAppRoot);
  
  
  
          ArrayList<clip> listVideos = new ArrayList<clip>();
  
          Clip clip = new Clip();
  
          clip.path = video1;
  
          fc.getInfo(clip);
  
          clip.duration = clip.duration;
  
          System.out.println("Clip1 duration " + clip.duration);
  
          listVideos.add(clip);
  
  
  
          Clip clip2 = new Clip();
  
          clip2.path = video2;
  
          fc.getInfo(clip2);
  
          clip2.duration = clip2.duration;
  
          System.out.println("Clip2 duration " + clip2.duration);
  
          listVideos.add(clip2);
  
  
  
          Clip clipOut = new Clip();
  
          clipOut.path = fileVideoOutput.getCanonicalPath();
  
  
  
          fc.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false,
  
                  new ShellUtils.ShellCallback() {
  
  
  
                      @Override
  
                      public void shellOut(String shellLine) {
  
  
  
                          System.out.println("fc>" + shellLine);
  
                      }
  
  
  
                      @Override
  
                      public void processComplete(int exitValue) {
  
  
  
                          if (exitValue &lt; 0)
  
                              System.err.println("concat non-zero exit: "
  
                                      + exitValue);
  
                      }
  
                  });
  
      } catch (Exception e1) {
  
          e1.printStackTrace();
  
      }

  Here is my ffmpeg commands as given in the ffmpeg tutorial page.

  ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
  
  ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
  
  ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

  FFMPEG library doesn’t seem to be working as expected. When I add commands and create output file using "touch" shell command file is being created. Still I am unable to see the output from ffmpeg as expected.
