Hi,

I want to know if it’s possible to disable hardware acceleration through SDK. I have a custom built application which is working fine on local system, while running in virtualbox vm I am getting exception “Setting ‘render’ is not supported at VideoOS.Toolkit…”.

I know how to disable it for XProtect client but want o do it for SDK so application will use ActiveX not DirectX for the rendering.

Regards

You can see it in use in the VideoViewerQuality sample.

EnvironmentManager.Instance.EnvironmentOptions["UseActiveX"] = true;

I tried but getting exception “Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))” at _imageViewerControl1.Initialize();

If I remove EnvironmentManager.Instance.EnvironmentOptions[“UseActiveX”] = “Yes”; it’s working fine.

EnvironmentManager.Instance.EnvironmentOptions["UseActiveX"] = "Yes";
 
                if (_imageViewerControl1 != null)
                {
                    _imageViewerControl1.Disconnect();
                }
                
                //List<Item> camCollection = EnvironmentManager.Instance.MasterSite.ServerId.UserContext.Configuration.GetItems()[0].GetChildren()[4].GetChildren()[0].GetChildren();
                List<FQID> fqids = new List<FQID>();
               
 
                List<Item>  camCollection = EnvironmentManager.Instance.MasterSite.ServerId.UserContext.Configuration.GetItems()[0].GetChildren()[4].GetChildren()[0].GetChildren();
                foreach (Item cam in camCollection)
                {
                    if (cam.Name == cameraName)
                        _selectItem1 = cam;
                }
 
                
 
                _imageViewerControl1 = ClientControl.Instance.GenerateImageViewerControl();
                _imageViewerControl1.Dock = DockStyle.Fill;
                //_imageViewerControl1.InfoText = cameraName;
                _imageViewerControl1.ClickEvent += new EventHandler(ImageViewerControl1Click);
                panel1.Controls.Clear();
                panel1.Controls.Add(_imageViewerControl1);
                _imageViewerControl1.CameraFQID = _selectItem1.FQID;
                _imageViewerControl1.Initialize();
                _imageViewerControl1.Connect();
                _imageViewerControl1.Selected = true;
                _imageViewerControl1.EnableMouseControlledPtz = true;
                _imageViewerControl1.EnableMousePtzEmbeddedHandler = true;
                _imageViewerControl1.EnableDigitalZoom = true;
                _imageViewerControl1.BackColor = System.Drawing.Color.Black;

PS. This is something I have not seen for a while, which tells me partners are using the newer component, but it used to be one of the top questions or issues.
