  We need your feedback !

  We all know and love the versatility of WordPress – with over 55,000 plugins and all the different ways of hosting it. However, with this great versatility comes the potential for things to be missed, so we’re keen to hear your feedback.

  • Is our plugin breaking anything on your WordPress, or, not compatible with something ? Please create an issue on our repository.
  • Is something not working ? If so, what ? Please create an issue on our repository.
  • How does running Matomo impact the performance of your WordPress server ? Also, if you have any other feedback for us – whether good or bad – please email us at wordpress@matomo.org. We’d love to hear what you think !
  • Can you perform a security review of the plugin ? Security issues are best reported to security@matomo.org
  • Do you have any questions ? Questions are best asked in our forum

  Thank you ! We really appreciate your help on this ❤️

  How do you get Matomo Analytics for WordPress ?

  Get Matomo for WordPress

  Log in to your WordPress and go to “Plugins => Add New”, search for “Matomo Analytics – Ethical Stats. Powerful Insights”, click on “Install” and then “Activate”.

  All you need is at least WordPress 4.8 and PHP 7.0 or later. MySQL 5.1+ is recommended. 

  The source code is available at : https://github.com/matomo-org/wp-matomo/. 
  

  In perfect harmony : Matomo and WordPress

  

  The idea for this started two years ago when we realised the similarities between the Matomo and WordPress project. 

  Not only from a technological point of view – where both are based on PHP and MySQL and can be extended using plugins – but also from a philosophical, license and values point of view. We both believe in privacy, security, data ownership, openness, transparency, having things working out-of-the-box, simplicity etc. 

  WordPress is currently used on approximately 30% of all websites. Many of them use the self-hosted open-source WordPress version. Giving everyone in this market the opportunity to easily get a powerful web analytics platform for free, means a lot to us. We believe WordPress users get a real choice besides the standard solution of Google Analytics, and it furthers our effort and goal of decentralising the internet. 

  We’re hoping more people will be empowered to protect user privacy, have access to a great free and open-source tool, and keep control of data in their own hands.

  We hope you feel the same. Help us spread the word to your friends and get them in on this awesome new project !

  FAQs

  Isn’t there already a WP-Matomo plugin for WordPress available ?

  Yes, the existing WP-Matomo (WP-Piwik) plugin is an awesome plugin to connect your existing Matomo On-Premise or Matomo Cloud account with WordPress. The difference is that this new plugin installs Matomo Analytics fully in your WordPress. So you get the convenience of having a powerful analytics platform within your WordPress.

  We highly recommend you install this new plugin if you use WordPress and are not running Matomo yet. 

  If you are already using Matomo on our Cloud or On-Premise, we’d still highly recommend you use WP-Matomo (WP-Piwik). So that you get an easier way of inserting the tracking code into your WordPress site and get insights faster.

  I have a high traffic website, will it be an issue ?

  If you have a lot of traffic, we’d advise you to install Matomo On-Premise separately. There’s no specific traffic threshold we can give you on when it’s better to use Matomo On-Premise. It really depends on your server. 

  We reckon if you have more than 500,000 page views a month, you may want to think about using Matomo On-Premise with WP-Matomo instead, but this is just an estimate. In general, if the load on your server is already quite high, then it might be better to install Matomo on a separate server. See also recommended server sizing for running Matomo.

  How do I report a bug or request a new feature in Matomo for WordPress ?

  Please create an issue, on our repository whenever you find a bug or if you have any suggestion or ideas of improvement. We want to build an outstanding analytics experience for WordPress !

  Have another question you’re dying to ask ? The Matomo for WordPress FAQ page might have the answer you need.

• Improve ffmpeg x11grab screen capture performance

  10 janvier 2020, par Toby Eggitt

  I have been doing screen-only (no sound) capture using ffmpeg with libx264 for the encoding quite successfully on an old machine built around a Core2 Quad Q6600 processor. I now need to include audio in this, but the fans on this ancient machine are too loud. So, I found a fanless motherboard (https://www.asrock.com/mb/Intel/J5005-ITX/index.asp) that has an Intel Pentium Silver J5005 processor and decided to use this instead. The CPU’s benchmarks put it in a similar bracket to the Q6600, and the general performance seems to be significantly better, presumably at least in part because it’s now using DDR4 memory that’s faster access.

  However, the machine fails horribly at the screen capture. It’s missing frames all over the place ; I actually end up with video that’s missing almost half the frames, and plays back at about double speed. Also, any audio is just messed up so badly I can hardly think how to describe it, best I can come up with is that I get perhaps a quarter second of sound then a few seconds pause (the video meanwhile is actually still playing back, albeit with no sense of time).

  Some things occur to me that might be the cause, or cure, of my troubles, some of which I might be able to fix, others not so much. What other things should I try ? (I’d prefer to avoid simply throwing money at the issue with random ideas that are baseless !)

  1) perhaps the CPU lacks some "extensions" to the instruction set (I recall years ago some CPUs gaining MMX extensions") so that the CPU is fast at mundane computing but sucks at video encoding.

  2) perhaps the fact that the old machine had a dedicated graphics card, while this new one is sharing main memory with the graphics system means that reading the screen pixels is much slower.

  3) perhaps the fact that this new machine has a single DDR4 memory stick in it means that I’m forcing all the memory reads and writes for the computations through the same memory as is holding the screen, and that’s too much (implying that adding an additional memory stick might jus possibly help ?)

  4) perhaps there’s some bios setting that would allow more efficient sharing of video memory ?

  5) my favorite, perhaps there’s a better compression library that I could use to get decent quality screen capture with much less CPU usage.

  I should also note that I have tried this with -threads 0, and the CPU usage hovers between 100% and 200% ; around 100% when the screen is static, and rising as I move windows around and otherwise create more output.

  6) the motherboard claims to have some kind of hardware video encoder built into it. I haven’t paid this any attention to this point, as I assumed it was for the purpose of taking HDMI input and encoding it, but maybe there’s a way to use this, if so, what libraries might I need to get ffmpeg to do this.

  Edits :

  • This is an off the shelf ffmpeg. I’m certainly willing to try building it myself if I have some idea what I should do different.
  • The motherboard claims to have hardware encoders, but I’m struggling to find out what they are (seems like it’s an Intel chip called "UHD Graphics 605" but nothing I can find suggests ffmpeg can work with that)

  • command line right now has been (without audio) :

    ffmpeg  -video_size 1280x720   -f x11grab  -i ${DISPLAY}+100,100  -vcodec libx264  -f alsa -i pulse -acodec ac3 -threads 0  ./video$(date +%F-%H-%M-%S).mp4

• Rails FFMPEG - convert to webm gives error for encoder 'libvpx-vp9'

  7 mai 2019, par Milind

  I am testing video conversion to convert video file into mp4 and webm.
  I have also setup ffmpeg and compiled properly.Mp4 conversion succeeds but webm breaks always complaining as -

  The encoder 'libvpx-vp9' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

  its strange as I aready have vp8 present -
