OpenCV Capture

OpenCV Capture is a straightforward compatibility path for cameras and capture devices exposed through DirectShow.

Controls

  • Capture source and refresh
  • Supported resolutions from 720p, 1080p, or 1440p
  • Supported frame rates from 30, 60, 120, 144, or 240 FPS for the selected resolution
  • Live Write FPS

Use

Select the device, then choose from the resolution and frame-rate combinations it reports. Start capture and confirm a stable write rate. Use this path when DS Capture or MF Capture has a device-specific compatibility issue or when working with an ordinary webcam.

Troubleshooting

  • Close other software using the camera.
  • Try 1080p/60 or 720p/60 before higher modes.
  • If OpenCV Capture works but has higher latency than another capture path, use the path that performs best with that device.
