• How to read remote video on Amazon S3 using ffmpeg

  9 septembre 2024, par virtualize

  I need to create poster frames from videos hosted on Amazon S3 via ffmpeg.

  



  So is there a way to use the remote video file directly in ffmpeg command line like this :
  
ffmpeg -i "http://bucket.s3.amazonaws.com/video.mp4" -ss 00:00:10 -vframes 1 -f image2 "image%03d.jpg"

  



  ffmpeg just returns :
  
http://bucket.s3.amazonaws.com/video.mp4: I/O error occurred<br />&#xA;Usually that means that input file is truncated and/or corrupted.

  



  I also tried forcing ffmpeg to use the videos mp4 container for reading :
  
ffmpeg -f mp4 -i "http://bucket.s3.amazonaws.com/video.mp4" ...
  
But no luck.

  



  Wget this video from S3 and processing it locally works fine of course,
  
as well as reading the file remotely from other 'standard' http servers.
  
So I know that ffmpeg supports remote file reading, but why not on S3 ?

  


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

  20 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,
