Hi, I am Julian

Over the past three months, I have been working on reverse-engineering the Canon C100 II's Browser Remote API to create a mobile remote control app. The result is a Flutter app which I'll showcase in this post, including my plans for the project.

When controlling a camera remotely, it is crucial to have a Live View preview to judge the composition and exposure. Luckily the Browser Remote API offers an endpoint to fetch the current Live View image. This post explains how you can enable the live view functionality and poll the current preview image.

After the previous parts described the setup and initialization of the Browser Remote API, this post finally explains how to use the API to control the state of a Canon C100 II. You'll learn how to start and stop a recording and adjust properties like aperture, iso and shutter speed.

The Canon EOS C100 II requires certain cookies as part of the request headers for the communication to work. This post describes how you can obtain all necessary cookies and keep property data in sync by polling for updates.

The Browser Remote function lets you control a Canon Cinema camera using a web interface. Since the communication is based on HTTP, I wanted to explore the underlying API to use it for my own projects. This article covers the setup process and the tools I used to reverse engineer the API.
