FFMPEG concat video throws No Such Filter error
5 janvier 2021, par Rohan ShahI am trying to concat three videos using FFMPEG,


This is my command that I am executing using Java Runtime


String command = "ffmpeg -i url_to_video -i url_to_video -i url_to_video -filter_complex [0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a] -map [v] -map [a] /home/rohan/output.mp4";

 Process process = Runtime.getRuntime().exec(command.split(" "));



This is throwing me No Such Filter error, whereas if I try to run this via Terminal it works perfectly fine. I tried tweaking the cmd by removing or adding quotes, but any variant of this command that runs on terminal throws error in Java Runtime. While it runs perfectly on the Terminal.


I have tried with Absolute paths and Amazon S3 URLs, while both of them work just fine in terminal, The S3 variant of command throws
No Such Filter
error and the Absolute path command throws aNo Such File Or Directory
error during Runtime.

Here is the stack trace of the error


Here is the standard error of the command (if any):

26 décembre 2016, par Jake MillerI have a web app where you can upload a video and a thumbnail is created for this video. It works completely fine on my machine, but as soon as I deploy to AWS (Amazon Web Services) as a .war file, I experience dependency issues with maven.

Premium Plugins now available on the Piwik Analytics Marketplace
2 novembre 2016, par Piwik Core Team — Community, Press ReleasesWe are super excited to announce the launch of three new premium plugins which are now available on the Piwik Marketplace : A/B Testing, Media Analytics, and Activity Log.
All three plugins are easy to use and come with 100% data ownership, documentation, integration with Piwik, powerful data exports and no data limits.
These first premium plugins and the new Marketplace capabilities have been designed and built with love by InnoCraft – the new company brought to you by the makers of Piwik.
1. A/B Testing
A/B Testing helps you grow your business by comparing different versions of your website or app to detect the most successful version that increases your sales, revenue, conversions, pageviews, and more.
A/B tests are also known as experiments or split tests. In an A/B test you show two or more different variations to your users (visitors) and the variation that performs better wins. When a user enters the experiment, a variation will be randomly chosen and the user will see this variation for all subsequent visits. Piwik A/B testing uses advanced statistical analysis to detect which variation performs better for your conversion goals and success metrics. Even small tests can increase your sales and conversions massively !
Learn more here :
- A/B Testing – Experiments (website).
- List of all features on the Marketplace : A/B Testing Plugin.

The A/B Testing User Guide and the A/B Testing FAQ help you getting started in running A/B tests. The A/B Testing developer guides help you embedding and implementing A/B tests into your project.

2. Media Analytics
Do you have videos or audio on your website, or in an app ? Media Analytics gives you powerful insights into how your audience watches your videos and listens to your audio, to ultimately maximize your success.
Learn all about your audience. Which media your users are playing, for how long, how often, and where they dropped off ? Where are your users located around the world ? Who your audience are and what did people do before and after watching a video or listening to audio ? Many of the reports are also available in Real time, so you can gain insights and react quickly.

It allows Piwik Super Users to quickly review the actions performed by members of your organization or clients, and also lets every user review details of their own actions.
