# Writing fragmented MPEG-4 files for HTTP Live Streaming

Create an HTTP Live Streaming presentation by turning a movie file into a sequence of fragmented MPEG-4 files.

## Overview

Overview note: This sample code project is associated with WWDC20 session 10011: Authoring Fragmented MPEG-4 with AVAssetWriter. Configure the sample code project Before you run the sample code project in Xcode: Edit the shared scheme called fmp4Writer. Open the Run action. Replace the <path to movie file on disk> argument with the path to a movie file on your local hard drive. Replace the <path to output directory> argument  with your desired output directory; for example ~/Desktop/fmp4writer/.
