SYNOPSIS
vainfo [--display type] [--device path] [options]
DESCRIPTION
vainfo displays information about the Video Acceleration API (VA-API) support available on the system. It queries the GPU driver and reports which video encoding and decoding profiles are supported, such as H.264, HEVC, VP9, and AV1.
The output includes the VA-API driver name, version, and a list of supported profiles with their entry points (encoding, decoding, video processing). This information is essential for diagnosing hardware video acceleration issues and verifying that the correct VA-API driver is loaded for the GPU.
