  What’s new in Piwik 2.10.0 ?

  Since our last release Piwik 2.9.1 one month ago, over 100 issues have been closed. We’ve focused on fixing bugs, improving performance, and we created a new plugin that will let you better scale Piwik to very high traffic websites using Redis.

  Much improved Log Analytics

  Log Analytics is the powerful little-known feature of Piwik that lets you import dozens of different server logs into Piwik. In Piwik 2.10.0 you can now import Netscaler logs, IIS Advanced Logging Module logs, W3C extended logs and AWS CloudFront logs. Piwik will also automatically track the username as the User ID and/or the Page Generation Time when it is found in the server logs.

  Better scalability using Redis (advanced users)

  At Piwik PRO we are working on making Piwik scale when tracking millions of requests per month. In this release we have revamped the Tracking API. By using the new QueuedTracking plugin you can now queue tracking requests in a Redis database, which lets you scale the Piwik tracking service. The plugin is included as Free/libre software in the core Piwik platform. More information in the QueuedTracking user guide.

  Better performance

  A few performance challenges have been fixed in this release.

  The Visitor Log and the Live API will render much faster on very high traffic websites. Any custom date ranges that you have selected as default in your User Settings (eg. ‘Last 7 days’ or ‘Previous 30 days’) will now be pre-processed so that your analytics dashboard will always load quickly.

  For users on shared hosting, the real time widgets could be use a lot of server resource as they are refreshed every ten seconds. We’ve improved this by only requesting data when the Browser Tab containing the Real time widgets is active.

  Other changes

  We packed in many other changes in this release such as compatibility with Mysql 5.6 and Geo location support for IPv6 addresses. A community member made Piwik compatible with Internet Explorer 9 when running in compatibility mode (which is still used in several companies).

  The Tracker algorithm has been updated : when an existing visit uses a new Campaign then it will force creating a new visit (same behavior as Google Analytics).

  If you need professional support or guidance, get in touch with Piwik PRO.

  Changelog for Piwik 2.10.0 – we plan to release Piwik 2.10.0 around 2015 Jan 5th.

  Happy Analytics, and we wish you a nice holiday season !

• Running ffmpeg via PHP

  11 mars 2020, par FionaF

  So the end goal is to have a php script that, given a list of images, will automatically create a slideshow video with transitions and text overlays and maybe an audio track as well.

  I’m competent in coding PHP but not experienced in command line stuff.

  We have a dedicated server and I got hosting company to install ffmpeg for me.

  So I thought I’d start simple and slowly build up to ultimate goal. But I’m really struggling. I’ve spent a couple of days trying all sorts of things with very little success.

  I found this post with some excellent examples https://superuser.com/questions/833232/create-video-with-5-images-with-fadein-out-effect-in-ffmpeg but I can’t get any of them to work. Which makes me think that I’m doing something fundamentally wrong.

  So this does work for me - I get a nice little 30 sec video slideshow of 6 images displaying for 5 secs each :

  $ffmpeg="/usr/bin/ffmpeg";
  
  exec($ffmpeg.' -f concat -safe 0 -i input.txt -c:v libx264 -r 30 -pix_fmt yuv420p -y out.mp4 2>&1', $output);
  
  var_dump($output);

  and this is input.txt

  file /home/webvivre/public_html/videos/test/i1.jpg
  
  duration 5
  
  file /home/webvivre/public_html/videos/test/i2.jpg
  
  duration 5
  
  file /home/webvivre/public_html/videos/test/i3.jpg
  
  duration 5
  
  file /home/webvivre/public_html/videos/test/i4.jpg
  
  duration 5
  
  file /home/webvivre/public_html/videos/test/i5.jpg
  
  duration 5
  
  file /home/webvivre/public_html/videos/test/i6.jpg
  
  duration 5

  But this (basically taken from example in link above - have only changed image names and ffmpeg location) doesn’t work for me :

  $code="/usr/bin/ffmpeg -y -loop 1 -i i1.jpg -loop 1 -i i2.jpg -loop 1 -i i3.jpg -filter_complex \" [0:v]zoompan=z='min(zoom+0.0015,1.5)':d=125,trim=duration=5,blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))',setpts=PTS-STARTPTS[v0]; [1:v]zoompan=z='min(zoom+0.0015,1.5)':d=125,trim=duration=5,blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))',setpts=PTS-STARTPTS[v1]; [2:v]zoompan=z='min(zoom+0.0015,1.5)':d=125,trim=duration=5,blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))',setpts=PTS-STARTPTS[v2]; [v0][v1][v2] concat=n=3:v=1:a=0, format=yuv420p[v]\" -map '[v]' -c:v libx264 -pix_fmt yuvj420p -q:v 1 out.mp4 2>&1";
  
  exec($code,$output);
  
  var_dump($output);

  This is the output :
