说明
vdpauinfo queries and displays the capabilities of the VDPAU (Video Decode and Presentation API for Unix) driver. It shows which video codecs can be hardware-accelerated and at what resolutions. The output includes API version, decoder profiles supported (MPEG1, MPEG2, H.264, VC1, HEVC, VP9, AV1), maximum resolution and macroblock limits for each codec, video surface formats, and output surface capabilities. This tool verifies that VDPAU is properly configured and helps determine which video content can benefit from GPU acceleration on NVIDIA hardware.
