A complete program with ready‑to‑use configurations for MPV on Windows, optimized for USB capture cards. Play with any HDMI video game console with minimal as possible latency and endless options.
- Play any console HDMI‑compatible console through your USB capture card using MPV.
- Minimal lag/latency – play your real console with lag almost as low as connecting it directly to a TV.
- Portable – copy the whole folder anywhere and it will work without reinstallation.
- Custom menu (right‑click or
ESC) with:- Shaders – improve image quality up to 4K or apply retro looks (CRT, VHS, Arcade, etc.).
- Shapes – change the screen geometry (curvature, keystone, etc.).
- Crop – crop the window to the exact size of an NSO system (GBA, NES, SNES, etc.).
- Bezels – overlay decorative borders (e.g., SNES NSO bezel) for an authentic feel.
- Window options – resize, reposition, always on top, and more.
- Screenshots – automatically save screenshots to your MPV folder.
- Video recording – record 30/60/90/120 second clips with good quality and small file size.
- Fully customizable – add your own bezels, shaders, and menu entries.
MPV alone can introduce noticeable latency when handling both audio and video from a capture card.
This setup splits the workload:
- MPV handles the video stream only.
ffplay(from the ffmpeg bundle) handles the audio stream only.
Both programs run silently, stay in sync, and together deliver minimal‑lag gameplay with audio and video.
- A PC with USB 3.0 (USB 2.0 works but performance will be noticeably worse).
- A capture card that supports 1080p60 and provides loop‑through (input + output) – e.g., “4K Ultra HD USB 3.0 HD Video Capture (MS 2131)” or any similar device.
- Your own official video game console.
- mpv player and ffmpeg/ffplay (see note below).
✨ Note on dependencies:
While this project does not bundle mpv or ffmpeg/ffplay due to licensing and size constraints, the includedInstaller_MPV-SW-Capture.exetool can download and place the correct versions automatically.
For most users, this is the simplest way to get started.
If you prefer, you can also obtain them manually from their official sources:

MANUAL Install
| Custom Menu | Shader + Shape example |
|---|---|

| Right‑click / ESC menu with shaders, bezels, crop, window and capture options. | Example of a CRT‑style shader + CRT Curved Shape applied through MPV‑SW‑Capture. |
| Bezel example | Crop example |
|---|---|
 |
 |
| Example bezel applied around the captured image for a more authentic look. | Window cropped to match a GB resolution in NSO, using the crop presets. Perfect if you don't want the normal borders. |
| Stretch window example | Combination example |
|---|---|
 |
 |
| Stretch Window option enabled to fill more of the screen while keeping the capture visible. | Example of a combination of Shader + Crop (to 4:3) + Stretch. Crop cannot be mixed with Bezel. |
Bezel images included in this project are generic CRT/handheld‑style frames (created/edited for this project) and are not official assets from any console or game. They are decorative overlays only.
