• AWS ffmpeg-lambda-layer and concat protocol (Node.js)

  25 février 2021, par portik

  I am trying to concatenate two .mp3 files using ffmpeg lambda-layer. I have what I think is the correct command, but I struggle to represent it in code so that it is formatted correctly for the lambda layer. Here is a piece of code that I am struggling to get right :

  


  spawnSync(
  '/opt/ffmpeg/ffmpeg',
  [
    '-i',
    '"concat:/tmp/pt1.mp3|/tmp/pt2.mp3"',
    '-acodec',
    'copy',
    `/tmp/${fileName}`
  ],
  { stdio: 'inherit' }
)


  


  The error I'm getting : "concat:/tmp/pt1.mp3|/tmp/pt2.mp3": No such file or directory.

  


  I tried to list files in /tmp/ folder - both files listed in the input are there, not sure why lambda layer can't find them.

  


  Similar question : https://lists.ffmpeg.org/pipermail/ffmpeg-user/2019-December/046299.html. Ffmpeg concatenate protocol documentation : https://trac.ffmpeg.org/wiki/Concatenate#protocol.

  


  Thanks in advance !

  


• Compile ffmpeg on Ubuntu 13.10 with libfdk_aac

  26 février 2014, par nitsuj

  I tried this guide, but I have an error that permission is denied when I try to run a script from PHP using exec(). I think that this is because ffmpeg is in /root.

  How can I install this where my PHP script can access it ?
