Now I manged to use the X11 grabber and the SIP client displays the 
video stream from the X11 grabber. But If I switch back to the webcam 
source, I do not see any video.

Further, I do not understand the syntax of the text below the video 
sources thumbnails, e.g when the incoming call is started:

webcam?      X11
+------+  +------+
|      |  |      |
|      |  |      |
+------+  +------+
  1+2 ON       ON

now, I left-click on the X11 thumbnail:

+------+  +------+
|      |  |      |
|      |  |      |
+------+  +------+
  2   ON     1 ON

now, I right-click on the X11 thumbnail:

+------+  +------+
|      |  |      |
|      |  |      |
+------+  +------+
    ON      1+2 ON


What does 1+2, or 1 ON, or 2 ON mean? I think middle-click complete 
turns a input stream on/of. But what is the difference of 
left-click/right-click on a thumbnail?

thanks
