• FFMPEG concat video throws No Such Filter error

  5 janvier 2021, par Rohan Shah

  I 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 a No 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):

• Maven dependency works on machine but not when packaged in a .war - org.bytedeco.javacpp.avutil

  26 décembre 2016, par Jake Miller

  I 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.

  Here’s the exception from the logs :

  Here are my maven dependencies for the ffmpeg wrapper I’m using :

  <dependency>
  
      <groupid>org.bytedeco</groupid>
  
      <artifactid>javacv</artifactid>
  
      <version>1.3</version>
  
  </dependency>
  
  <dependency>
  
      <groupid>org.bytedeco</groupid>
  
      <artifactid>javacpp</artifactid>
  
      <version>1.3</version>
  
  </dependency>

  I’ve tried various different versions but nothing has worked so far. What’s strange is the error says org.bytedeco.javacpp.avutil but I have access to the avutil class in my IDE.

  EDIT

  I’ve also tried everything at this github post : https://github.com/bytedeco/javacpp-presets/issues/225

  No solution I’ve found has worked. I’ve tried various different versions and various different org.bytedeco dependencies but they all yield the same error.
