hi,
I am sending the onpreviewFrame byte array to socket. it send the
first image but due to onPreviewframe callback it does not send any
image and go to Exception. I want to send images to socket
continuously. what's the reason. Here is my code & logCat result
public void surfaceCreated(SurfaceHolder holder) {
// The Surface has been created, acquire the camera and tell it
where
// to draw.
//////////////////connection to server
try {
socket = new Socket("192.168.1.220", 8888);
obj = new ObjectOutputStream(socket.getOutputStream());
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
camera = Camera.open();
try {
camera.setPreviewDisplay(holder);
camera.setPreviewCallback(new PreviewCallback() {
// Called for each frame previewed
// @SuppressWarnings("null")
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();
//YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format ==
ImageFormat.YUY2 || format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h,
null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, w, h);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 100, output_stream);
byte[] byt=output_stream.toByteArray();
try {
obj.writeObject(byt);
obj.flush();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
Preview.this.invalidate();
}
}
});
obj.close();
} catch (IOException e) {
e.printStackTrace();
}
}
