ffmpeg.setFfmpegPath(ffmpegInstaller.path)

var counter = 0

var Mywatcher = chokidar.watch('Z:\\WatchFolder', {ignored: /^\./, persistent: true, usePolling: true});
Mywatcher
  .on('add', function(path) {
    worder = '.mp4'
    if(path.includes(worder)){
 
            counter = counter + 1 
            
            console.log('added' + counter)

            ffmpeg({ source: path })
            .on('filenames', (filenames) => {
                console.log('Created file names', filenames);
            })
            .on('end', () => {
                console.log('Job done');
            })
            .on('error', (err) => {
                console.log('Error', err);
            })
            .takeScreenshots({
                filename: counter +'.jpg',
                timemarks: [ 2 ],
             
            }, 'public/images/thumbnail/');
      
    }

    })

  .on('change', function(path) {console.log('File', path, 'has been changed');})

• Trouble installing ffmpegthumbnailer on Amazon Linux AMI

  30 août 2014, par jnbankston

  I am trying to install ffmpegthumbnailer on a Ec2 instance using Amazon linux. Ffmpeg has been compiled successfully and is working.

  This is my configuration when compiling from source
  ./configure —prefix=/tmp/ffmpegthumbnailer_dir/ —enable-shared —enable-png —enable-jpeg —enable-static —with-pic PKG_CONFIG_PATH=/root/ffmpeg_build/lib/pkgconfig/

  This is the error when I try to make the binary.

  /usr/bin/ld : /root/ffmpeg_build/lib/libavformat.a(allformats.o) : relocation R_X86_64_32 against

  ff_a64_muxer' can not be used when making a shared object; recompile with -fPIC

• 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,
