- video-capture-plan.html: recording a region of one screen to H.264 MP4 and into the library as a video .mcap. DXGI Desktop Duplication first, on a device of its own on the screen's adapter; Windows.Graphics.Capture when duplication cannot run (two GPUs, rotated screens, too many duplications). Encoders tried in turn: NVENC, AMF, QSV, Media Foundation, libx264, from the FFmpeg already shipped. Ctrl+PrintScreen opens the overlay in a video mode (a 240 x 180 minimum, kept to one screen) and stops the recording. Five phases, the first a command-line probe that answers the two-GPU question on the laptop.
