Overview
To manage the video sequence currently broadcasted by the Web camera installed on the current computer, WINDEV proposes:
You have the ability to:
  • view the video broadcasted by a Web camera.
  • save an image from the broadcasted video in an image file (BMP, JPEG, ...).
  • save a section of the broadcasted video in a video file.
  • ...
Note: To view a video in AVI format, use an Image control and the MCI functions.
Principle
To handle the videos:
  1. Create a window containing a Web Camera control.
  2. Display the description window of this control ("Description" from the popup menu).
  3. In this window, select the Web Camera to use.
    Note: The Web camera to use can also be specified by programming (VideoSetDriver).
  4. By programming:
    • Display the video sequence currently broadcasted by the specified Web camera in the Web Camera control (VideoDisplay).
    • Save (if necessary) the video currently broadcasted by the specified Web camera in image format (BMP file) or as a video sequence (AVI file) with VideoCapture.
    • Modify (if necessary) the Web camera used (VideoSetDriver).
    • Configure (if necessary) the driver for video capture (VideoConfigure).
    • List (if necessary) the drivers for video capture installed on the current computer (VideoListDriver).
    • Return (if necessary) the status of Web Camera control (VideoStatus).
    • Stop displaying or saving a video sequence in the Web Camera control (VideoStop).

Notes

  • At run time, the video sequence broadcasted by the associated Web Camera is automatically displayed as soon as the window containing the Web Camera control is opened. In this case, there is no need to use VideoDisplay.
  • If no Web camera was associated with the Web Camera control, VideoDisplay and/or VideoCapture handle the video sequence broadcasted by the default Web camera (on the current computer).
  • To save the video currently broadcasted by the specified Web camera in the format of an image file, you can use:
