Running FFmpeg on AWS Lambda for 1.9% the cost of AWS Elastic Transcoder

  • Instead, well be using Exodus to bundle FFmpeg inside of an AWS Lambda function for performing transcoding tasks.
  • Lambda is a relatively good fit for something like a simple Youtube MP3 downloader service, but thats already pushing the limits of what a single Lambda invocation can handle.
  • So say that you tracked down all of these dependencies, placed them in a subdirectory, and then set the environment variable to before invoking FFmpeg in your Lambda function.
  • If that file doesnt exist in the Lambda execution environment, then FFmpeg wont runeven if all of the libraries are the search path.
  • The second part of the series will focus on building YouTube MP3 downloader service, while this part is solely focused on bundling FFmpeg and making a self-contained transcoding function.
