CANoeCamera

Vector CANoe configuration integrating Image/Video capture using AForge.NET. Compatible with any camera that interfaces with DirectShow on Microsoft Windows.

Based upon the latest AForge.NET code with the following modifications:

• Update projects to target .NET Framework 4 Client Profile
• Integrated IAMVideoProcAmp change (details)
• Updated FFMPEG to release 4.3.2 (build)
• Backported code from Accord.NET to allow AForge.Video.FFMPEG to integrate with newer versions of FFMPEG
• Removed parts of AForge.NET that are not required for just Image/Video capture

Writing to the System Variables in the CANoe configuration allows for control of the camera interface:

System Variable	Description
CameraProperties	Structure containing the following elements: CameraControlProperty Pan Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Tilt Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Roll Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Zoom Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Exposure Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Focus Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value VideoProcAmpProperty Brightness Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Contrast Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Hue Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Saturation Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Sharpness Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Gamma Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value ColorEnable Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value WhiteBalance Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value BacklightCompensation Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value Gain Override: flag to force user or default values Flag: flag to select manual or auto control UserValue: value to set when forcing user value DXbutton: map to a panel button to enable showing the default DirectShow Control Panel when connected to a camera Note: The minimum, maximum and default values are set for use with a Microsoft® LifeCam Studio(TM); if you use a different camera then update these values to reflect what is appropriate for your camera!
CurrentCamera	The friendly name of the camera currently being used
PreferredCamera	Structure containing the following elements: Name: The friendly name of the preferred camera, if it is not available then the first camera shall be used Height: The preferred image/video height to capture, if it does not match a supported resolution then the largest available resolution shall be used Width: The preferred image/video width to capture, if it does not match a supported resolution then the largest available resolution shall be used
SnapShotFileName	The filename of an image to be saved, updating this variable trigger saving the next available video frame as an image. File format is judged based upon file extension.
VideoBitRate	The bitrate to be used when saving video data
VideoFileName	The filename of a video to be saved. FFMPEG uses the default codec based upon the file extension
VideoState	Toggle between Stopped (0) and Running (1) in order to begin or end video recording

Note: If WebCam is added to an existing CANoe configuration then the name of the sysvar dll referenced in WebCam/WebCam.csproj will need to be modified to reflect the name of the new CANoe configuration name.

Sysvars can be added to an existing project by importing WebCam/Canoe/WebCam.vsysvar

Info: This node uses a callback whenever a new frame is available from the camera which can have some unintended behaviour:

• If the exposure value is set too long then you will not receive the expected frame rate from the camera which will cause any recorded video to playback too fast
• If the exposure is set to Auto and the lighting enviornment changes then any recorded video may contain time dilation due the the exposure dynamically modifying the frame rate
