• 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
/root/ffmpeg_build/lib/libavformat.a: could not read symbols: Bad value

• 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 :

  Any help would be greatly appreciated,
