- Decoder Device
The information of the decoder device is displayed.
- Processor Device
The Information of the processor device by DXVA1, DXVA2, DXVA-HD and Direct3D11 is displayed.
- About Resolution of Decoder Device
This result does not guarantee whether the decoder device works normally (in especially 4K/8K resolution).
Because IDirectXVideoDecoderService::CreateVideoDecoder might return S_OK even if resolution exceed the capability of hardware.
How it behaves depends on display driver.
- DirectShow / Media Foundation Decoder
By specifying the media file or format,
you can check whether the DirectShow decoder and Media Foundation decoder registered in the system support DXVA,
and the DXVA mode that is supported.
You can also use the listed decoders to play the video and measure the decoder's CPU or DXVA decoding performance.
You can also change the DXVA settings for the following decoders.
- CyberLink H.264/AVC Decoder
- CyberLink VC-1 Decoder
- CyberLink Video/SP Decoder
- CyberLink Video Deocder
- InterVideo Video Decoder
- Microsoft MPEG-2 Video Decoder
- Microsoft DTV-DVD Video Decoder / Microsoft H264 Video Decoder MFT / Microsoft MPEG Video Decoder MFT
- Microsoft H265 Video Decoder MFT
- Microsoft WebM MF VP8 Decoder Transform
- Nero DVD Decoder / Nero Video Decoder
- WMVideo Decoder DMO
- WMVideo Decoder MFT / AMD Playback Decoder MFT
- Trace Log
You can check DXVA API calls in running applications.
- GPU Engine Usage (Windows10 only)
You can check the usage of the GPU engine for each process.
Only the actual usage of the engine is displayed as "Current [Minimum-Maximum]".
