Small and efficient screen recording utility for Windows 10 and 11.

wcap uses Windows.Graphics.Capture API available since Windows 10 version 1903, May 2019 Update (19H1) to capture contents of window or whole monitor. Captured texture is submitted to Media Foundation to encode video to mp4 file with hardware accelerated codec. Using capture from compositor and hardware accelerated encoder allows it to consume very little CPU and memory.
