    draw into video stream from camera


    I am trying to do some real time image processing on the
    video stream from the camera. I already found out that
    you can use the "player" and "video control" classes to display
    the video stream coming from the camera and get a snapshot.

    What I need however goes beyond this:

    Is there a way to get a function called whenever a new preview
    frame arrives from the camera ?

    The function could then alter the video stream, e.g. apply some filter onto the pixel data, before it is displayed....

    davidmanpearl describes briefly a manual (and slow) way to do something along these lines here http://discussion.forum.nokia.com/fo...ad.php?t=84289

    The same discussion contains also reference to overlay control, which is part AMMS (JSR-234), but not yet available on handsets.

    hi Davidyes,

    you will need implement your own timebase control (ticker) for use during record session, If I'm not wrong PlayerListener (see Mobile Media API docs) broadcast only events on start/stop/error of record process,
