If you want to overlay an image on top of the video or still images, you have to wait until JSR-234 (Advanced Multimedia Supplements API - more specifically camera features) is available on handsets. OverlayControl is the one you are probably looking for.

See a earlier thread here

hi Muhammad,

guessing from what Hartti posted that's not possible on Nokia devices,
in MIDP/JSR specification is noted that even if you can draw camera over canvas (direct mode) it's not guaranted that you will be able to draw something over video content because that all up to device manufacturer how to implement that (if choose to support or not),
So that's how things are with current implementat of mobile media, but will change with future implementation (again what Hartti pointed),

hi Muhammad,
i'm not C++ coder,
could be possible or not, here is similiar discussion on Symbian section:
http://discussion.forum.nokia.com/fo...ad.php?t=68270
I've remember similiar example from Sun WTK 2.5 samples (get video shapshot to image and then do anything you want with that image, but that's not the same as real-time overlay over video player/canvas,

Peter

[mshouab]

will you please send me some sample code how it can be achieved through JSR 234 or some link where i can found this thanks in advance.

hi,

SUN WTK 2.5 beta comes with example codes for JSR-234:
http://java.sun.com/products/sjwtool...nload-2_5.html
Nokia Prototype 4 also supports that JSR:
http://www.forum.nokia.com/main/0,6566,034-761,00.html
and that recent doc from nokia comes with complete documentation for that JSR:
online:
http://www.forum.nokia.com/ME_Develo...ary/index.html
download:
http://www.forum.nokia.com/info/sw.n..._v1_0.zip.html

Note that there is no phone with that JSR from Nokia yet, as Hartti posted, so you can use emulators only,

hth,

Hello Shoab,

I see your interested in overlaying one image on another. I have done some very similar to this.

1. By using CFbsBitmap I use Primitives such as setRect or DrawRect to draw whatever I want on top of the camera captured image. hence overlaying or mapping anything I want on the desired camera captured image. In order to perform things like this you have to study the SDK for Symbian Nokia FP2. Search for CFbsBitmap.

2. Another neat trick is to use OpenGL ES ( http://www.khronos.org/opengles/1_X/ ) for texture mapping. So you can load the image you want to overlay in a CFbsBitmap, keep it as a PixMap surface using OpenGL ES and then map it on anything else using OpenGL ES primitives which you read about here ( http://www.khronos.org/opengles/docu...tml/index.html ). You might want to start by studying the OpenGL ES examples provided with Symbian SDKs for example the simplecube example. I was able to capture show images from the cellphone camera and was able to render a moving and rotating cube on top of it. It looked really cool.

Hope this helps.

hi Muhammad,

have you looked into mentioned few times Sun WTK 2.5 samples already?
it contains various samples in advanced multimedia suplements folder,
for example if I remember well ImageEffectMidlet (or simliar name) which shows exactly what you want: Overlay effects, transposition, filters, etc,

hth,

peter

[hartti]

Hi Muhammad, there will be AMMS tutorials on Forum Nokia in the future, but not yet as those features are not yet available on real devices. I hope WTK samples help you in your development efforts.
