Using dxcap to capture Direct3D11 video decoding API RRS feed

  • Question

  • Hi!

    I'm trying to capture the operations of a video decoding application that uses Direct3D 11 for hardware accelerated video decoding.

    I started dxap with the command-line: dxcap -c testapp.exe

    However the resulting capture log only contains enumeration of the DXGI adapters and creation of the IDirect3DDevice instances via D3D11CreateDevice (with the D3D11_CREATE_DEVICE_VIDEO_SUPPORT flag set).

    I do not see any video related calls (i.e. ID3D11VideoDevice::GetVideoDecoderProfileCount or ID3D11VideoDevice::CreateVideoProcessorEnumerator).

    Does dxcap support capturing these interfaces?

  • Hi IndyJone,

    We could use Visual Studio to simply config the capture options.

    TOOLS->Options->Graphics Diagnostics

    We could let the dxcap collect everything of call stacks during capture.

  • Hi Wang,

    Thanks for your reply. I tried to choose that option but still did not see any video-related calls being captured - I guess this is currently not supported ...

    Cheers, Martin

    I agree with you, since for everything is checked, all the supported call stack will be seen on your side.
