Installation
Hardware requirements, DeckLink setup, and installing packages.
Hardware Requirements
| Component | Minimum | Recommended |
|---|---|---|
| OS | Linux (Debian 12+) or Windows 10+ | Debian 13 |
| GPU | Vulkan 1.1 capable | NVIDIA RTX or AMD RDNA2+ with recent drivers |
| CPU | x86_64, 4 cores | 8+ cores for headroom with HDR metering |
| RAM | 4 GB | 8 GB+ |
| Capture | Blackmagic DeckLink card | DeckLink Mini Recorder 4K or higher |
A Vulkan-capable GPU is required. The rendering pipeline uses libplacebo's Vulkan backend for all scaling, tone mapping, and shader processing.
DeckLink Setup
Install a supported Blackmagic DeckLink capture card (PCIe or Thunderbolt).
Download and install the Desktop Video drivers from Blackmagic Design support.
Open Blackmagic Desktop Video Setup and verify your card is detected. Confirm that the correct input (HDMI or SDI) is selected and showing the expected signal format.
The application defaults to HDMI input on DeckLink device index 0. Connect your HDMI source before launching.
TIP
The DeckLink SDK supports automatic input format detection. When the source changes resolution or frame rate, the application will restart capture with the new format automatically.
