Convert .mp4 and .mov files from S3 into multiple Gif animations for timeline scrubbing.
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 applicaiton (link in resources section) to view the gif animation.
First, deploy this fmpeg Lambda layer.
