• PHP with FFMPEG

  29 août 2015, par SJ04

  I am trying to run ffmpeg code on the server via PHP and here is my code :

  <?php
  
  $command ='find /mnt/'.$year.' /mnt/2015/ -name '.$_POST['MXF'].'.mxf';
  
  if (!($stream = ssh2_exec($con, $command))) {
  
              echo "fail: unable to execute command\n";
  
          } else {
  
  
  
              stream_set_blocking($stream, true);
  
              $stream_out = ssh2_fetch_stream($stream,SSH2_STREAM_STDIO);
  
              $file = stream_get_contents($stream_out);
  
              echo $file;
  
              $t==$file;
  
              echo $t;
  
              $ff='/usr/bin/ffmpeg -i '.$t.' -vcodec libx264 -pix_fmt yuv420p -profile:v baseline -level 3.0 -s '.$RESOLUTION.' -vb '.$VB.'k -ac 2 -acodec aac -b:a 128k -ar 44100 -strict -2  -vf "movie=/datastore/logo/hello_logo.png [watermark]; [in][watermark] overlay=60:main_h-overlay_h-60 [out]"  '.$NDRIVE.''.$MXF.'.mp4 -y';
  
              if(!($tra= ssh2_exec($con, $ff))) {
  
              echo "failed to execute the Command";
  
          }
  
  ?>

  and when I copy the file path from the $file command, I get the file path but when I use PHP variable $file within the FFMPEG code, I get error of -vodec not found

  I want to pass the $file variable which contain the file path on the server into the FFMPEG code.

• Catalyst Open Source Academy

  16 janvier 2015, par Matthieu Aubry — Community

  The Open Source Academy is an initiative designed to provide training and work experience for young New Zealand technologists. Catalyst organises the Academy to show young technologists how to participate in open source communities and to fully explore their passion for IT through freely available open source tools.

  It has been running annually since 2011. We are proud that Piwik project could participate in the Academy again this year !

  What students got done

  It’s amazing what a few young students can get done in four days of participating in an open source project like Piwik ! They were able to quickly get started with Piwik, and continued to make useful contributions to the Piwik analytics platform.

  New Darkness theme

  Liam has created a new dark theme for Piwik called Darkness.

  

  To create the theme, Liam had to improve Piwik core stylesheets and created this pull request : Reuse the LESS variable for white color across all stylesheets.

  Accessibility improvements

  We were lucky to spend time with Julius, a Catalyst employee who is blind. He showed us in great detail how difficult and time consuming it can be for a blind user to use Piwik. For example we noticed how complicated it was for Julius to navigate the menus, to get to the main content, and to use the calendar and the Website selector. During this presentation we also noticed that Piwik was not yet usable with the keyboard.

  As a result of this session with Julius we got to work with the students to improve accessibility in Piwik.

  List of accessibility improvements

  All these pull requests were created by the students and have been successfully merged into Piwik :

  • see the focus of menu items when tabbing through the page
  • Tweaks to improve accessibility (section around graph, better tooltip, set language in html)
  • Added h3 tags to widget headers
  • when main Menu is focused, display submenu
  • Add “Skip to content” feature when user presses tab key
  • Improved accessibility by putting offscreen text in the widget title

  To learn more about accessibility in Piwik check out this issue on our tracker.

  Summary

  Working with young students was fun and interesting. We were excited to see how much they got done in such a short time !

  At Piwik and Piwik PRO we are committed to building the best open analytics platform, and we will continue to support students who want to take part in the Piwik adventure.

  Be well,

  x86/tx_float : enable SIMD for sizes over 131072
  The tables for the new sizes were added last year due
  
  to being required for SDR.
  
  However, the assembly was never updated to use them.
