• How can I get neighbour frames when implementing my own ffmpeg filter ?

  10 septembre 2019, par Aaron

  I’m implementing a custom FFmpeg filter. When frame N is processing, I hope I can also get the information of frame N-1 and frame N+1. Is there any FFmpeg function I could use for some help ?

  In my custom FFmpeg filter, the filter_frame function provides an AVFrame object, which is the Nth frame, but how can I get the former and the latter AVFrame object.

  static int filter_frame(AVFilterLink *link, AVFrame *in)

• Copy audio files into single file using ffmpeg

  11 septembre 2019, par Gunaseelan

  I used following command to copy many files into single file,

  ffmpeg -i AUD-20180413-WA0057.mp3 -i AUD-20180531-WA0001.mp3 -vn -acodec copy MergeAudio_1568168063082.mp3

  This code copies only first file into output file,

  However, following command works

  ffmpeg -i AUD-20180413-WA0057.mp3 -i AUD-20180531-WA0001.mp3 -filter_complex [0:a][1:a]concat=n=2:v=0:a=1[a] -map [a] MergeAudio_1568168372267.mp3

  But this command takes too much time as it is re encoding,

  That’s why I tried with copy [I hope if the files are same stream it will work], but the command I have given is copy only first file.

  Thank you ! We really appreciate your help on this ❤️

  How do you get Matomo Analytics for WordPress ?

  Download Matomo for WordPress

  You can then upload it in your WordPress by going to “Plugins => Add New”. During the upload, if you get an error like “Are you sure you want to do this ?”, we recommend you upload the extracted zip file on to your server and into your ‘wp-content/plugins’ folder manually using ftp or ssh. Make sure the plugin name is ‘matomo’.

  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.
