• How to run FFMPEG with —enable-libfontconfig on Amazon Linux 2

  22 avril 2024, par Adrien Kaczmarek

  Problem

  


  I want to run FFmpeg on AWS Lambda (Amazon Linux 2) with the configuration --enable-libfontconfig enable.

  


  Situation

  


  I already have FFmpeg running on AWS Lambda without the configuration --enable-libfontconfig.

  


  Here is the step I took to run FFmpeg on AWS Lambda (see official guide) :

  


  

  • Connect to Amazon EC2 running on AL2 (environment used by Lambda for Python 3.11)

  


  • Download and package FFmpeg from John Van Sickle

  


  • Create a Lambda Layer with FFmpeg

  


  


  Unfortunately, the version built by John Van Sickle doesn't have the configuration --enable-libfontconfig enabled.

  


  Unsuccessful Trials

  


  I tried to rebuilt it from scratch following the installation guide but without success (and the guide doesn't install font related dependencies)

  


  I tried to install it with brew but the command brew install ffmpeg didn't succeed on AL2.

  


  I tried to install ffmpeg from ffmpeg-master-latest-linux64-gpl.tar.xz. Unfortunately, this build of ffmpeg doesn't run on AL2 :

  


  ffmpeg: /lib64/libm.so.6: version `GLIBC_2.27' not found (required by ffmpeg)
ffmpeg: /lib64/libpthread.so.0: version `GLIBC_2.28' not found (required by ffmpeg)
ffmpeg: /lib64/libc.so.6: version `GLIBC_2.27' not found (required by ffmpeg)
ffmpeg: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by ffmpeg)


  


  Any help would be greatly appreciated,

• ffmpeg throwing "errorMessage" : "spawn ffmpeg ENOENT"

  My ffmpeg function thats running as a shell command isnt working. I think its because 'ffmpeg' isnt really referring to anything. I have the ffmpeg node module in my bundle, but i dont know the execFile command is referring to it here.

  



  Im following aws-lambda-ffmpeg as an example of how to call this particular function. They are referring to 'ffmpeg' as a 64-bit linux build they created from John Vansickle's static FFMPEG builds in their gulp function.

  



  I want to know how to replace 'ffmpeg' with something that will just recognize it like a node_module without having to do the whole gulp static build process. To my understanding the only reason they are doing that is to get the latest build which i really dont need.

  



  If I am wrong and a static build using gulp is needed for another reason please let me know.

  



  function ffmpegProcess(description, cb) {
console.log('Starting FFmpeg');

child_process.execFile(
    'ffmpeg',
    [
        '-y',
        '-loglevel', 'warning',
        '-i', 'download',
        '-c:a', 'copy',
        '-vf', scaleFilter,
        '-movflags', '+faststart',
        '-metadata', 'description=' + description,
        'out.' + config.format.video.extension,
        '-vf', 'thumbnail',
        '-vf', scaleFilter,
        '-vframes', '1',
        'out.' + config.format.image.extension
    ],
    {
        cwd: tempDir
    },
    function(err, stdout, stderr) {
        console.log('FFmpeg done.');
        return cb(err, 'FFmpeg finished:' + JSON.stringify({ stdout: stdout, stderr: stderr}));
    }
);
}
