Release Notes

V4.8.0_May/2026

New Features

• Supported acquisition, parsing, and saving Bayer BRGG8 format images.
• Added the following parameters in CameraParams_header.MV_GIGE_DEVICE_INFO.
  • nHostIP: During device enumeration, it returns the IP address of the host currently occupying the camera (requires camera support).
  • nMulticastIP/nMulticastPort: It refers to the multicast IP address or the multicast port.
  • nGenTLType: It refers to the device type (0: CameraParams_const.MV_GIGE_DEVICE GigE vision device, 1: CameraParams_const.MV_VIR_GIGE_DEVICE Virtual GigE vision device, 2: CameraParams_const.MV_GENTL_GIGE_DEVICE Self-developed NIC-based GigE vision device).
• Supported settings of endianness for saving TIFF images via nEndian field of CameraParams_header.MV_CC_SAVE_IMAGE_PARAM or CameraParams_header.MV_SAVE_IMAGE_TO_FILE_PARAM_EX.
• Added an API for inputting images in HB and JPEG formats: MV_CC_InputOneFrameEx() .
• Optimized the API MV_GIGE_IssueActionCommand() to support parallel operation.
• Supported data forwarding under XoFLink protocol.

  Note

  • By connecting the frame grabbers in series, the main one forwards the received data to the sub ones, allowing multiple frame grabbers to acquire the same image source synchronously.
  • Only some frame grabbers support data forwarding. You can select the appropriate connection method for your scenario (connection in series or parallel).

• Supported splitting image via CoaXPress frame grabber.
• Supported splitting large image over 4 GB via XoFLink frame grabber.
• Supported frame retransmission for GigE vision camera.
• Added some status codes in Status Codes.

Improvements

• Improved performance of HB image decoding.
• Optimized parameter importing/exporting.
• Optimized image acquisition strategy.
  • Supported cameras connected to frame grabber.
  • Supported UpcomingImage mode of USB3 vision camera.
• Optimized image grabbing logic of USB3 vision camera, improving compatibility with low-performance devices.

V4.7.0_November/2025

New Features

• Supported rendering and saving RGB 12 format images.
  • Supported rendering RGB 12 format images in GDI, D3D, and OpenGL modes.
  • Supported calling MV_CC_SaveImageEx3(), MV_CC_SaveImageToFileEx(), and MV_CC_SaveImageToFileEx2() to save RGB 12 format images.
• Optimized the APIs MV_CC_DisplayOneFrameEx() and MV_CC_DisplayOneFrameEx2() to support rendering images in PixelType_Gvsp_YUV420SP_NV12 and PixelType_Gvsp_YUV420SP_NV21 formats.

  Note

• Optimized the API MV_CC_ConvertPixelTypeEx() to support converting Bayer pixel format to RGB Planar format.
• Optimized event related features.
  • Supported registering events for multiple handles of a frame grabber at the same time in a single-process environment. In a process, if you call MV_CC_RegisterEventCallBackEx() for handle A and handle B respectively to register the same event M, both handle A and handle B will receive event M at the same time.

    Note

    When registering the same event multiple times for the same handle, the previously registered callback function and custom information will be overwritten.

  • SDK supported receiving CoaxPress camera event.

Sample Programs

Added the following sample programs:

• Recording.py : It shows how to save videos recorded by the camera.
• Grab_LineStart.py : It shows how to set the line scan camera to get images in the specified thread.
• BasicDemoLineScanCamera.py : It shows how to use line scan cameras, including initializing SDK resources, enumerating devices, and creating instances and handles.

V4.6.0_June/2025

First release. Provides Python APIs to support basic features.
