Graphics and Video Decode Inspector

Graphics and Video Decode Inspector is a desktop graphics adapter, display connector,
video acceleration driver, and codec capability utility for Linux.
An independent Linux alternative inspired by desktop video decode capability viewers, it
inspects kernel DRM devices, DRI render nodes, installed VA-API and Mesa driver modules,
and video codec acceleration support with JSON and CSV reporting.

Key Features:
- DRM GPU & Display Connector Inspection: Enumerates /sys/class/drm graphics cards,
display connectors, supported video modes, EDID status, /dev/dri renderD nodes, and
kernel driver module details including /proc/driver/nvidia when present.
- Host VA-API, VDPAU & Mesa Driver Inventory: Detects installed *drvvideo.so VA-API
backends, Mesa *_dri.so drivers, VDPAU libraries, and EGL/Vulkan vendor ICD manifests
with ELF architecture and byte size details.
- FFmpeg HWAccels & Video Codec Matrix: Queries bundled FFmpeg -hwaccels, software and
hardware video decoders/encoders across H.264, HEVC, AV1, VP9, VP8, MPEG-2, and ProRes,
and measures real 720p video decode frame rate throughput.
- Structured JSON & CSV Export: Exports full GPU node, driver inventory, and codec
acceleration matrices to JSON and CSV reports.
