Cross platform screen capture library

Frametap

frametap is very early in development. Definitely do not use it just yet.

A cross platform screen capture library for MacOS, Windows, and Linux.

Frametap can:

• Deliver live frame information from your screen.
• Capture GIFs.
• Export frames as PNGs.

Why?

I wanted a screen capture app that lets me control the compression, quantization, dithering, etc. Surprisingly, there's nothing that can do all that on all three major OSes (well, except for FFMPEG – but that's a command line tool).

Hopefully, once the library is mature, I'll be able to use it to build such an app. While I'm still figuring thngs out, you can try LICECap — it's pretty solid!

Goals

• Cross platform
  • MacOS: ScreenCaptureKit and CoreGraphics (AVFoundation at some point).
  • Windows: Win32 API.
  • Linux: Figure something out with Wayland / dbus.
• Fast. Drop as few frames as possible.
• Control over parameters such as FPS, Quantization algorithm, dithering, etc.
