README

This code allows to use D3D11 IDXGIOutputDuplication in Go

Examples

• Encoding an mjpeg stream examples/mjpegstream
• Recording an h264 video using ffmpeg for transcoding examples/recording

Libaries used

• golang.org/x/exp/shiny/driver/internal/swizzle for faster BGRA -> RGBA conversion (see shiny LICENSE)

app.manifest

To make use of IDXGIOutput5::DuplicateOutput1, an application has to provide support for PerMonitorV2 DPI-Awareness (Windows 10 1703+) This is usually done by providing an my-executable.exe.manifest file either next to the executable, or as an embedded resource.

In the examples there are calls to IsValidDpiAwarenessContext and SetThreadDpiAwarenessContext which circumvent the requirement.
