How to Enable FSR Upscaling in MPV Player

What is FSR (FidelityFX Super Resolution)?

FSR, or FidelityFX Super Resolution, is an upscaling technology developed by AMD (Advanced Micro Devices) to improve the visual quality of lower-resolution images or videos in real-time. It is designed to enhance the gaming and multimedia experience by providing a more detailed and sharper image without significantly impacting performance.

Here we are going to apply the same fsr techinque to mpv media player to upscale the lower resolution videos.

Step 1: Install MPV

Windows

Download the installer from the official MPV website and follow the installation instructions.

Linux

Ubuntu/Debian

sudo apt-get install mpv

Fedora

sudo dnf install mpv

Mac

brew install mpv

Step 2: Create a Shaders Directory

Windows

1. Navigate to appdata. This is typically located in %APPDATA%. You can quickly navigate there by entering this path into the File Explorer’s address bar.
2. Create a Folder “mpv” inside that folder.
3. Inside the “mpv” folder, create another folder named “shaders”.

Linux/Mac

mkdir -P ~/.config/mpv/shaders

Step 3: Download the FSR Shader into shaders folder

Windows

1. Open your web browser and go to this website https://gist.github.com/agyild/82219c545228d70c5604f865ce0b0ce5
2. Click on the Download ZIP button on the top right corner.
3. Extract the downloaded file, where you can find fsr.glsl.
4. Copy that fsr.glsl into newly created shaders folder.

Linux/Mac

Run this command to download the FSR shaders into shaders folder

curl -Lo ~/.config/mpv/shaders/FSR.glsl https://gist.githubusercontent.com/agyild/82219c545228d70c5604f865ce0b0ce5/raw/2623d743b9c23f500ba086f05b385dcb1557e15d/FSR.glsl

Step 4: Modify MPV Configuration File

Windows

1. open the mpv folder and create a text file input.conf
2. Paste the following lines and save it.

CTRL+1 no-osd change-list glsl-shaders set "~~/shaders/FSR.glsl"; show-text "FSR"
CTRL+0 no-osd change-list glsl-shaders clr ""; show-text "GLSL shaders cleared"

Linux/Mac

1. Run this command to create/open input.conf file

nano ~/.config/mpv/input.conf

2. Paste the following lines and save it.

CTRL+1 no-osd change-list glsl-shaders set "~~/shaders/FSR.glsl"; show-text "FSR"
CTRL+0 no-osd change-list glsl-shaders clr ""; show-text "GLSL shaders cleared"

Usage Instructions

Play a video which is lower than your display resolution and press ctrl+1 to enable FSR and ctrl+0 for disable FSR.
