Maven dependency works on machine but not when packaged in a .war - org.bytedeco.javacpp.avutil
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.
Here’s the exception from the logs :

org.bytedeco.javacpp.avutil
but I have access to theavutil
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.

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):
