I can't find any good reference on how to change the 2.4.4 tutorials to work with the front facing camera. Can someone point me in the right direction please?

With this in the manifest:

<uses-feature android:name="android.hardware.camera.front" android:required="true"/>

And this in onCreate:

mOpenCvCameraView.selectCamera(1);

Which calls in OpenCVDemo2View:

public void selectCamera (int i) {
    mOpenCvCameraView.releaseCamera();
    mCamera.open(i);
    }

... I get images from the default camera - same if I don't try to select a camera. But if I use selectCamera(0) I get a message saying, "It seems that you [sic] device does not support camera (or it is locked). Application will be closed."

Any pointers to good info on this would be welcomed.

Many thanks

Barry

I have removed your original post because it contained language not agreed in this forum. Please check the FAQ for what is allowed or not allowed here. While the answer was pertinent, we do not tolerate anything but politeness and courtesy. For questions that are asked again and again, there is a "Mark as duplicate" tool. For low-quality questions, there is the down-vote button, etc

Ok noted. I kinda did know why it was removed, as mentioned just beneath the topic, in talkin with Barry I already appoligized. Could have placed just a simple edit on my post, removing two lines, but didn't get the chance.

So basically I know what should and should not be posted, it was just the frustration of the moment :)

I know this frustration - sometimes I just want to delete a lot of garbage here, but we all have to abide to the rules. Btw, I deleted your post because if I only put a note, it's hard to get back and monitor the changes. The rule here is to delete what's bad: http://answers.opencv.org/question/1038/how-to-handle-inappropriate-editing-habits/

Btw, the actual Mark as duplicate, where can I find that?

Hmmm, I am not sure is avaliable for all. It seems to be a moderator tool.
