    On Screen display during vedio recording

    Hi ,
    Nokia displays the current scene being recorded. I want to place some additional text on the screen while Nokia is recording. Is this feasible?
    How can change the on screen display (with or without recording) dynamically ?
    Thanks
    Kiran

    Re: On Screen display during vedio recording

    Are you now talking about a MIDlet? (I guess so as you are asking this question on Java boards)
    Do you want to have the text on top of the videofeed? This is not possible on Nokia devices, unfortunately (some Sony Ericsson phones apparently support it)
    If you are talking about text outside the video area, then yes, it is possible to do that. You just have to add/draw the things on the Canvas the normal way.

    Thumbs up Re: On Screen display during vedio recording

    Thax for the reply. You are right i am looking for a midlet which can display additional text or graphics in the viewfinder. I found in C++ forums that it is possible by taking snap shots as BMP(or png) , add your graphics , display the modified images. The draw back is that it will be slower.

    There is a project in python http://geral.etc.br/invisibles/index.html
    I need similar code in java.
    Has any one implemented this logic in java. Can u please share the sample code.


    Thanks
    Kiran

    Hi Kiran,

    drawing over video/still images in Java ME is possible by using OverlayControl from AMMS.

    Unfortunately, it is not available on Nokia devices yet, so you should try an approach similar to the one you describe for C++: so capturing, adding your graphics, and displaying the modified images.

    Hope it helps,
    Pit

    Hi Kiran,

    unfortunately I have not related sample code to share, but you could try to implement it by:

    * using getSnapshot() to get the current Player snapshot
    * creating a mutable Image with the snapshot content
    * adding your custom graphics over the snapshot
    * display the image and restart from first step

    Hope it helps,
    Pit
