Hardware Decode Compatibility
UMedia leverages your GPU's dedicated video decoding silicon (ASIC) to handle massive 4K and 8K bitstreams, keeping your CPU cool and fans quiet.
NVIDIA (NVDEC)
GeForce GTX 1000 series and newer.
AMD (VCN)
Radeon RX 400 series and newer.
Intel (QuickSync)
7th Gen Core CPUs (Kaby Lake) and newer.
Hardware Decoder API Selection
UMedia defaults to hwdec=auto-safe, which attempts to use the most stable zero-copy hardware API for your platform. If you encounter green screens or artifacts, you can explicitly define the API in umedia.conf.
| Platform | Preferred API string | Fallback (Copy) |
|---|---|---|
| Windows (NVIDIA/AMD) | d3d11va | d3d11va-copy |
| Windows (Intel) | dxva2 | dxva2-copy |
| Linux (NVIDIA) | nvdec | nvdec-copy |
| Linux (AMD/Intel) | vaapi | vaapi-copy |
| macOS | videotoolbox | videotoolbox-copy |
