DXVA Checker怎么破？？

别再折腾解码器了！用DXVA Checker和GPU-Z一键排查Chrome播不了H265视频的硬件元凶每次在Chrome里点开H265编码的视频却只看到黑屏或报错，你是不是也经历过这样的循环：疯狂搜索"H265解码器下载"→安装各种编解码包→重启浏览器→问题依旧？问题的根源很可能不在软件层面，而是你的显卡硬件根本不支持H265硬解——就像试图用收音机播放蓝光碟片，装再多播放软件都是徒劳。：如果你的HEVC条目下只有"Not Supported"或者完全缺失该条目，这就是Chrome无法播放的铁证。最讽刺的是，有些第三方解码器安装后反而会导致Chrome的硬件加速功能被禁用，造成更多播放问题。阅读详情

DXVA Checker 功能企图实现，可是Decoder Device部分只做到了DXVA2.0检测。DXVA1.0的API就是找不到。
还有就是Processor Device也无法实现。怎么破？
附上DXVA2.0检测的Code：



    IDirectXVideoDecoderService * pDecoder = NULL;

    IDirect3D9        *pD3D = NULL;

    IDirect3DDevice9  *pDevice = NULL;



    // Set up structure to create D3D Device

    D3DPRESENT_PARAMETERS d3dpp;

    ZeroMemory( &d3dpp, sizeof( d3dpp));

    d3dpp.Windowed = TRUE;

    d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;

    d3dpp.BackBufferFormat = D3DFMT_UNKNOWN;



    // Set up structure to create D3D Device

   if( FAILED( pD3D = Direct3DCreate9( D3D_SDK_VERSION)))

   {

       RT_LOG("Failed to Create Direct3D9!\n");

       return E_FAIL;

   }

   RT_LOG( "Success to Create Direct3D9 !\n");

   if( FAILED( pD3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, this->m_hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, 

       &d3dpp, &pDevice)))

   {

       RT_LOG("Failed to Create Direct3D9 Device!\n");

       return E_FAIL;

   }

   RT_LOG( "Success to Create Direct3D9 Device!\n");



   if( FAILED( DXVA2CreateVideoService( pDevice, IID_PPV_ARGS(&pDecoder))))

   {

       RT_LOG("Failed to CreatVideoService!\n");

       return E_FAIL;

   }

   

   UINT nCount;

   GUID* pGuids;



    if( FAILED(pDecoder->GetDecoderDeviceGuids( &nCount, &pGuids)))

    {

        RT_LOG("Failed to Get Decoder!\n");

        return E_FAIL;

    }

    CString src;

    for( UINT i =0; i < nCount; i++)

    {

        for (int j = 1; j < _countof(DXVA2Decoder); j++) {

            if (pGuids[i] == *DXVA2Decoder[j].Guid) {

                WriteConsole( hOutPut, DXVA2Decoder[j].Description, _tcslen(DXVA2Decoder[j].Description), NULL, NULL);

                WriteConsole( hOutPut, _T("\n"), _tcslen( _T("\n")), NULL, NULL);

                break;

            }

        }

        src ="";

        src.Format(_T("%08X-%04X-%04X-%02X%02X%02X%02X%02X%02X%02X%02X\n"), pGuids[i].Data1, pGuids[i].Data2,

            pGuids[i].Data3, pGuids[i].Data4[0], pGuids[i].Data4[1], pGuids[i].Data4[2], pGuids[i].Data4[3], 

            pGuids[i].Data4[4],pGuids[i].Data4[5],pGuids[i].Data4[6],pGuids[i].Data4[7]);

        WriteConsole( hOutPut, src, src.GetLength(), NULL, NULL);

    }   





     

    pDecoder->Release();

    pDevice->Release();

    pD3D->Release();

    

    return S_OK;
