DXVA Checker is a Windows utility designed to analyze and verify hardware video acceleration capabilities through DXVA (DirectX Video Acceleration). The software provides detailed information about decoder devices, processor devices, supported video acceleration modes, and the compatibility of installed video decoders.
The application is mainly intended for users who need to inspect how their system handles hardware-assisted video decoding. It can display information about decoder devices and processor devices using DXVA1, DXVA2, DXVA-HD, and Direct3D 11 technologies. DXVA Checker allows users to check whether registered DirectShow and Media Foundation decoders support DXVA acceleration for specific media files or video formats. It can also display supported DXVA modes and provide options to test video playback performance using available decoders.
The tool includes diagnostic features for monitoring DXVA API calls through trace logs and checking GPU engine usage on Windows 10 and Windows 11. This makes it useful for identifying which GPU engines are active during video processing and understanding hardware acceleration behavior. DXVA Checker also provides information about decoder device support for graphics hardware from manufacturers including AMD, Intel, NVIDIA, and Qualcomm. It is a specialized utility designed primarily for users who want detailed technical information about their video playback hardware and decoder configuration.
Features of DXVA Checker

Interface and Usability
DXVA Checker is designed as a technical diagnostic tool rather than a general media application. Its interface focuses on presenting detailed hardware and decoder information, making it useful for users who want to understand how video acceleration works on their system.
The application organizes information around decoder devices, processor devices, and system components. Users can examine whether specific decoders support DXVA and identify available acceleration modes for different video formats. The tool is particularly valuable when troubleshooting video playback performance or checking whether a system is using hardware decoding correctly. However, because it provides detailed technical information, it is better suited for advanced users, developers, and enthusiasts familiar with video codecs and GPU acceleration.
Who Should Use DXVA Checker?
- Video playback enthusiasts
- Users troubleshooting hardware acceleration issues
- Developers working with DirectShow or Media Foundation
- Users testing GPU video decoding capabilities
- System administrators analyzing multimedia performance
- Anyone who needs detailed information about DXVA support
Conclusion
DXVA Checker is a specialized diagnostic application for examining hardware video acceleration on Windows systems. Its ability to inspect DXVA support, analyze decoders, monitor GPU usage, and test decoding performance makes it a useful tool for technical users who need detailed playback information.
