    But it is a more precise question here so I write that here too :)
    I'm using a jit.qt.movie + jit.gl.videoplane + jit.gl.render to display (perfectly :p ) my movies + subtitles.
    I want to "inject" a png inside that flow.
    It would be at a particular moment (on a particular event): that png appears and disappears.
    no problem to track the event, the appear/disappear BUT, I cannot find the way to "inject" in that flow.
    How can I do?
    Any tips would be very appreciated !!!

      I'm sorry to make a "up up" but I really need that :-/

      can't you just put it onto another video plane? check out the following attributes:
      layer
      enable
      blend_mode
      it's actually a bit vague what you mean by ""inject" in that flow", which could be why you aren't getting any responses.

      hello David,
      I'm sorry for the vagueness...
      would you sketch me a patch to display a png on a videoplane?
      I'm stuck with that

      ok, now i'm really confused where you are having a problem. it's the same method you described above:
      png >> jit.qt.movie >> jit.gl.videoplane
      just play with the attributes I mentioned above, but again you aren't really explaining what you mean by "inject"

      David,
      I found my way by using blending (basic default mode 6 7) between 2 videoplanes.
      by "inject", I wanted to explain the fact I had already one videoplane displaying my video + subtitles AND I wanted to "add" (understand: to blend/mix) another video matrix.
      I did that with
      jit.qt.movie --- jit.gl.videoplane with blend/layer etc.
      thanks again
      I improved my patch (and knowledge :)
