This application creates a Step Functions workflow that runs when a new movie file is uploaded to an S3 bucket. The Workflow runs multiple Lambda functions concurrently, each invocation is responsible for generating it's own .gif clip. A 1 hour movie takes about 4 seconds to generate 120 gifs. the first Lambda function uses ffmpeg to work out how long the video is and how many chunks (gifs) will be needed for the whole video. The chunks are loaded into a MAP state. The next Lambda uses ffmpeg to build the .gifs. Use the timeline scrubber application (link in resources section) to view the gif animation.
Deploy this fmpeg Lambda layer.
cd /gif-generator
sam build && sam deploy -g
Upload a .mov or a .mp4 into the deployed S3 source bucket. This triggers the workflow to start generating .gif images. .gif images are saved into the S3 destination bucket.
- Either deploy the VUE application from the frontend folder or go to s12d.com/gif
- Enter the source file location e.g.
https://gif-source-bucket.s3.amazonaws.com/demo.mov - Enter the destination bucket.
- Scrub through the timeline to see the generated .gifs
