Overview of the Conference control

Window control

The Conference control allows you to view and/or listen to video and/or sound in real time.
To create a Conference control:
  1. In the window editor, on the "Creation" pane, in the "Graphic controls" group, expand "Video and capture" and select "Conference".
  2. Click at the desired location to create the control. The control appears in the editor.
To view the control characteristics, select "Description" in the popup menu of the control.
Remark: From version 20, Conference controls are supported in Windows Vista and later. If you want to use the Conference control with an earlier Windows version:
  1. Open the control description window.
  2. In the "UI" tab, check "Use the TAPI 3.x APIs / Windows XP (for compatibility)".
  3. Validate.
Principle
Several WINDEV functions allow you to handle communication streams via the Conference control. For more details, see:
This allows two users to communicate between themselves. The image and the voice of the users are broadcasted in real time on each connected computer.
Examples of applications that use the stream:
  • video-conferencing
  • broadcasting a live press conference
  • ...
Versions 20 and later
Remark: You also have the ability to establish a dialog between the Conference controls in a different private network via Internet. This type of dialog uses WebRTC technology. This technology requires the use of a STUN server and a TURN server. See WINDEV and the streams for more details.
