Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -

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):

ffmpeg code not working aws lambda environment
5 janvier 2021, par Akash DasI followed this article and deployed the Lambda functions and layers and set it up all fine.


But I am facing a problem when I try converting the mp4 video into a 720p video, the ffmpeg commands that work in my Ubuntu 20.04 are not working in the Lambda and gives me error in the form of 0kb files in the destination folder.


Can someone explain why this is happening ? The command that I used was :


ffmpeg -i input.mp4 -s 1280x720 -c:a copy output.mp4



I use this command in the Python file


ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -f mp4 -s 1280x720 -c:a copy -" ___ . 



This is the error I get :




The problem is that I used a code like this to get only the audio


ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -f mp3 -ab 192000 -vn -" ___ . 



And it works as expected.
