    Hi,

    I want to draw lines , multiline and area over the frame taken from video source via threaded way to not block to main thread. And also want to edit this drawing move , resize and delete.

    What is the convenient way to do this ? Is there any example ?

      Hi
      A Quick way would be to use this example
      https://doc.qt.io/qt-6/qtwidgets-graphicsview-diagramscene-example.html
      and combine it with a QGraphicsVideoItem
