Hello all,
I have the following code that gets called from my
main activity to capture a full Frame Image with the camera.
I've tried many differnt combinations of callback requests, but I
NEVER get a Jepeg Callback, though I do get all the other callbacks.
// **************************************************************
public void TakeFullFrameImage()
{
if(mCam != null)
{
Date currenttime = new Date();
long Timeout = currenttime.getTime() + 3000;
mCam.stopPreview();
mCam.takePicture(ShutterCb, RawCb, PostViewCb, JpegCb);
// *** [ShutterCb, RawCb, PostViewCb, JpegCb] ****
// mCam.takePicture(ShutterCb, RawCb, PostViewCb, JpegCb );
// ** [ The above Gets ShutterCb, RawCb, & PostViewCb only ]
// mCam.takePicture(ShutterCb, RawCb, PostViewCb, null );
// ** [ The above Gets ShutterCb, RawCb, & PostViewCb ]
// mCam.takePicture(ShutterCb, RawCb, null, null );
// ** [ The above Gets ShutterCb & RawCb ]
// mCam.takePicture(ShutterCb, null, null, null );
// ** [ The above Gets ShutterCb only ]
// mCam.takePicture(ShutterCb, null, PostViewCb, null );
// ** [ The above Gets ShutterCb & PostViewCb ]
// mCam.takePicture(ShutterCb, null, null, JpegCb );
// ** [ The above Gets ShutterCb only ]
// mCam.takePicture(ShutterCb, null, PostViewCb, JpegCb );
// ** [ The above Gets ShutterCb & PostViewCb ]
// mCam.takePicture(null, RawCb, null, null );
// ** [ The above Gets RawCb only ]
// mCam.takePicture(null, RawCb, PostViewCb, null );
// ** [ The above Gets RawCb, & PostViewCb ]
// mCam.takePicture(null, RawCb, PostViewCb, JpegCb );
// ** [ The above Gets RawCb, & PostViewCb only ]
// mCam.takePicture(null, null, PostViewCb, null );
// ** [ The above Gets PostViewCb only ]
// mCam.takePicture(null, null, null, JpegCb );
// ** [ The above Gets no callback
while( (currenttime.getTime()) < (Timeout) )
currenttime = new Date();
mCam.startPreview();
}
}
// ********************************************************
I print out some debug info about the data each call back receives,
the log is below.
I always receive the Shutter Callback when I request it.
The Raw Callback always receives a NULL for the data parameter,
the PostView Callback recieves data, but it is much too small,
and is NOT a jpeg, and I never receive the Jepeg callback
even if request it.
The code is running on a samsung galaxy SII. Which according
to mCam.mCamParameters.getSupportedPictureFormats() only supports
ImageFormat.JPEG and nothing else.
So...Why don't I get a Jpeg callback...?
Pleas feel free to ask for additional information if you
think you might know what is wrong, but need more explaination.
