The minimal, extensible screen capturer.

🚧 Disclaimer: this is an ongoing project under active development, and is not yet meant to be usable. 🚧

What's this?

TL;DR: Captain is an extensible screen capturing app that Just Works™ (on Windows).

It's meant to take screenshots and record the screen. These captures may be saved to a file or uploaded to the internet, or actually just about anything as long as there is an extension for that (and if there's not then go ahead and roll your own!)

The whole thing is built with extensibility and flexibility in mind. That means it doesn't matter whether you want to record WebM, HEVC or GIF videos or upload them to Imgur, your favourite pomf clone or whatever.

It also means we'll capture the screen appropriately no matter what thing's on it (i.e.: full-screen games)

Building from source

Environment Requirements

• Windows 7 SP1 or newer (build only tested on latest Windows 10)
• Visual Studio 2017 or newer (Community edition is fine)
  VS 2015 will most likely not work.

Cloning

The project is split in git submodules, so don't forget the --recursive flag when cloning.

$ git clone --recursive https://github.com/CaptainApp/Captain
$ cd Captain

Building

Then you can either open Captain.sln on Visual Studio or build it from the command-line:

$ nuget restore
$ devenv Captain.sln /Build

Extending Captain

You can build extensions by inheriting from common classes on the Captain.Common namespace.

Refer to the Captain.Common source tree for more on this. There will be documentation, eventually.
