Classic GDI COM Hosting

Heimdall offers 2 modes; a classic GDI mode, where the rendering is done entirely in software, and there is a 1:1 between a video feed and COM instance. The other mode uses HW accelerated rendering and one COM instance handles multiple streams.

In Basic GDI mode, a much larger number of auga instances can be made, each instance consuming less memory and using the window GDI system to draw video. GDI mode should be used for applications that require many (>8) independent Auga controls running concurrently, or where Direct3D acceleration is not available (PC’s without a GPU, virtual machines, servers etc)
