• GLIBCXX_3.4.9 not found when running ffmpeg from php in lampp server

  14 novembre 2020, par Rafaf Tahsin

  I've written a php program which creates a video from sequence of images using ffmpeg.

  



  <?php
    $res = shell_exec("ffmpeg -framerate 50 -i image/image%d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4 2>&1");
    echo "$res";


  


  When I run it,

  


  it says GLIBCXX_3.4.15 , GLIBCXX_3.4.9 , GLIBCXX_3.4.11 not found.

  


  


  ffmpeg : /opt/lampp/lib/libstdc++.so.6 : version `GLIBCXX_3.4.15' not

  


  found (required by /usr/lib/i386-linux-gnu/libjack.so.0) ffmpeg :

  


  /opt/lampp/lib/libstdc++.so.6 : version `GLIBCXX_3.4.9' not found

  


  (required by /usr/lib/i386-linux-gnu/libzmq.so.3) ffmpeg :

  


  /opt/lampp/lib/libstdc++.so.6 : version `GLIBCXX_3.4.11' not found

  


  (required by /usr/lib/i386-linux-gnu/libopencv_core.so.2.4) ffmpeg :

  


  /opt/lampp/lib/libstdc++.so.6 : version `GLIBCXX_3.4.9' not found

  


  (required by /usr/lib/i386-linux-gnu/libopencv_core.so.2.4)

  


  


  But from the terminal, ffmpeg -framerate 50 -i image/image%d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4 command works fine. Why php can't find the libraries while from the terminal it works fine ? and what should I do to fix the problem in php ? Thanks in advance.

  


• How to check for corrupt mp3 files using ffmpeg in nodejs

  2 septembre 2022, par Oliver Wagner

  Using the 'ffmpeg-static' npm package I managed to integrate ffmpeg in my node application, and run the [example][1]https://github.com/eugeneware/ffmpeg-static/blob/dce6d42ba772a5769df8181e704772db4456ef16/example.js code.

  


  The gist of the code is :

  


  import pathToFfmpeg from "ffmpeg-static";
import shell from 'any-shell-escape';
import { exec } from "child_process";

 function runFfmpeg(src, dest) {
  //where src is a existing mp3 file in a folder and dest is the destination folder
  const script = shell([
    pathToFfmpeg,
    '-y', '-v', 'error',
    '-i', resolve(process.cwd(), src),
    '-acodec', 'mp3',
    '-format', 'mp3',
    resolve(process.cwd(), dest),
  ]);

  exec(script);
}


  


  This works and this decodes and encodes the source file into mp3 and saves it in the dest folder.

  


  However, when I try what should be the simplest ffmpeg terminal command, such as ffmpeg -i file.mp3 -hide_banner it does not work. I have tried

  


  function runFfmpeg(src, dest) {
  const script = shell([
    pathToFfmpeg,
    '-i', resolve(process.cwd(), src), '-hide_banner'
  ]);

  const fileInfo = exec(script);
  return fileInfo;



  


  In the end, where I want to get to is being able to use my runFfmpeg function to check if an mp3 file has any missing or corrupted frames, using a terminal command that I found in the interwebs :
ffmpeg -v error -i video.ext -f null

  


  Any ideas on how to do that ?

  


• What's the simplest way of installing ffmpeg on my server (on a Mac) ?

  13 octobre 2011, par Nick

  I am looking to install ffmpeg on my server to enable audio files uploaded to a website to be converted to MP3. I understand that I need to install ffmpeg and ffmpeg-php, but I am not sure how to do this. I am wondering what the simplest way of doing this would be on my Mac. Would I need to use Terminal and learn command line methods, or is there a simpler way ? I have checked with my host that I have SSH access.
