Reading waveform data in ffmpeg

Reading waveform data in ffmpeg

When working on an audio player, I wanted to extract the audio waveform data to paint the audio waveform dynamically in the browser on a <canvas> element.

Initially I used the bbc/audiowaveform package but this proved problematic for a number of reasons. First I wasn't able to install that package (or build the binary) in macOS for local dev. The other big issue is that I was only able to figure out how to install it on Ubuntu, so I couldn't use it in Alpine (for Docker images) or other environments like cloud functions.

Initial approach

I found out from these docs it's possible to paint a waveform with ffmpeg by extracting raw audio data:

Adaptive Streaming with MPEG-DASH and HLS using AWS

Adaptive Streaming has become the neccessity for streaming video and audio. Unfortantely, as of this post, there isn't a whole lot of tutorials that accumulate all of the steps to get this working. Hopefully this post achieves that. This post focuses on using Amazon Web Services (AWS) to transcode for HLS and DASH and be the Content Delivery Network (CDN) that delivers the stream to your web page. We'll be using Video.js for the HTML5 player as well as javascript support libaries to make Video.js work with HLS and DASH.

So Here's what you need:

Set up three S3 buckets
