fluent ffmpeg generate video thumbnail set file size

We want our thumbnails to be visible to the world.Next we will need another bucket to store our generated thumbnails.įor the thumbnail bucket we need to enable public access. Go to the AWS Console, search for S3 and click 'Create bucket'.Įnter a unique name and then click 'Create bucket', leaving all the defaults blank: The first thing we need is an S3 bucket that we can upload our videos to. Trigger Lambda when video is uploaded to S3 1.1. Here's a link to the GitHub repo containing the Lambda code.ġ. I recommend setting up billing alerts if you haven't already. However, it is your responsibility to keep your costs under control and I make no guarantees of it being free. It is theoretically possible process thousands of videos and stay within the free tier. No frameworkįor anything Lambda related I recommend using the Serverless Framework, but in order for this article to have the broadest utility I will use the AWS Console. This is, however, much more expensive at approximately $0.45 for every 60 minutes of video processed. For even larger files it may be possible to attach an EBS Storage Volume to your Lambda, but that is outside the scope of this tutorial.Īn alternative is to use AWS Transcoder for generating thumbnails. The maximum size of the tmp storage has now increased to 10GB, so we're able to process much larger videos. When this article was first written, that folder was limited to 512MB of storage, meaning the largest video that could be processed was 512MB. We use the /tmp/ storage folder within Lambda functions for downloading videos for processing.

This article came about from the work I did on that.

I needed to generate thumbnails for my Serverles Media Portal project, a home video sharing platform that I was building. Use FFmpeg to generate thumbnails from the video & upload to S3.Add the FFmpeg executable to your Lambda.Use the AWS-SDK to read the video into the Lambda.This article will be divided into 4 sections, each of which will demonstrate how to: Generate thumbnails using Lambda from videos uploaded to S3
