Drawing on video canvas

[t1amir@walla.co.il]

hi

the next simple code play a video

Player player = Manager.createPlayer(_url);
player.realize();
player.prefetch();

VideoControl vc = (VideoControl)player.getControl("VideoControl");

if (vc != null){
vc.initDisplayMode(VideoControl.USE_DIRECT_VIDEO , canvas);
vc.setDisplayLocation(0,0);
vc.setDisplaySize(100,100);
vc.setVisible(true);
}
player.start();


I want to draw on top of the video, can some amend the code in a way that when drawing on canvas it will be on top the video.

I saw in other threads here that OverlayControl can do the trick somehow.if I am not mistaken OverlayControl is relevant for imageeffect and not video.
Can someone assist?
I am using n95

Unfortunately drawing on top of the video is not possible on (all) devices. It might be possible to do that on some devices but at least on Nokia devices not.

hi Hartti

Can you give me code example for devices that can draw on top of video canvas.

Hi Tamir,

you can start taking a look at OverlayControl JavaDocs, since they contain useful infos (and some code) to start understanding how to use it to draw on top of videos:

Note that, as told by hartti, it's currently not supported on Nokia devices.

Hi

What about something like extending the Player class and somehow intercating with the function that does the drawing on the Graphics object.

Is this very complex to implement on nokia jvm

Potential solutions:
1) Use Symbian C++ (Python/PyS60 might also do the trick, I do not know)
2) get snapshots in a row, draw those on the screen and draw on top of those images (you will not achieve great frame rate though)
3) change your application logic/behavior so that you do not have to draw on top of the video

The workaround you are suggesting does not work, as you do not have low-level access to the players.

hi

I saw that the limitation is also true when Player is playing animated GIF.

Is there any workaround for this issue?
Is the any way to draw on top of animated gif?

Well, not a solution (since the answers above are still valid, even for GIFs when used within a Player), but a workaround:

you could export the single frames of your gif, and reproduce its animation with Java code (so, with single Graphics drawImage() method calls). Done that, you'll be able to draw over that what you prefer, since you'll not be using Player objects anymore.
I know it's not an easy approach, but for some tasks it could be suitable..

Hope it helps,
Pit
