Camera view rotated 90 Degrees on C7

[stefanz]

Hello out there,

I am developing a camera handling in JavaME. Now a got a 'funny' effect I do nevertheless do not want. On the device C7-00 the camera view is rotated 90 Degrees. On N97 Mini the camera view is shown correctly. In both cases the snapshot taken is in the correct orientation. I use the same Jar for both devices.

I am using portraitmodus only (Flag Nokia-MIDlet-App-Orientation is set to portrait). Removing this Flag solves the problem with the camera orientation, but I want to keep it, as the camera is only part of a bigger application which runs into graphical problems on rotations without it. So I could remove it and fix the graphical problems in the rest of the application wihch will cost quiet a lot of time. Any better solutions?

Here the code to initialize the VideoControl.

private void initMyPlayer() throws IOException, MediaException, SecurityException, Exception
    {
        mPlayer = null;
        mPlayer = Manager.createPlayer("capture://video");
        mPlayer.realize();

        // Grab the videocontrol and set it to the current display
        mVideoControl = null;
        mVideoControl = (VideoControl) (mPlayer.getControl("VideoControl"));
        if (mVideoControl == null)
        {
            throw new Exception("Couldn't create VideoControl");
        }

        mVideoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO , MyMIDlet.mCanvas);

        mVideoHeight = mVideoControl.getSourceHeight();
        mVideoWidth = mVideoControl.getSourceWidth();
        
        mVideoControl.setDisplayLocation(0, 0);
        mVideoControl.setDisplaySize(mVideoWidth,mVideoHeight);
        mVideoControl.setVisible(true);

        mPlayer.start();
    }

        mPlayer.start();
    }

try with - USE_GUI_PRIMITIVE instead of USE_DIRECT_VIDEO in mVideoControl.initDisplayMode();

Hy im2amit,

thank you for your reply. I changed everything to USE_GUI_PRIMITIVE instead of USE_DIRECT_VIDEO. I can see the the camera view again - but still rotated (.

If I remove the flag, the camera view is not rotated as I sayed. I now found, that the snapshot itself is rotated then. (

I already tried out a free app I downloaded (FaceWarp). There the camera view is shown correctly, after taking the photo it is shown 90 Degrees rotated for a moment and then in the correct orientation again. Seems to me they had the same problem there, got a 90 Degrees rotated picture and calculated the backrotated image, showing the not rotated image on mistake. As this download is only ment for C7, this was a workaround made exspecially for this mobile. So it seems to me, this a C7 bug (while the normal mobile camera is working correctly).

Do you agree this is a C7 bug or do you have another idea?
