hi,
I am getting the frames from onPreviewFrame method, and convert
these frames to jpeg and send it on a network. but i want the size of
each image to QVGA that is 320x240. Please tell me what is the right
way to convert the onPreviewFrame to QVGA, but i am doing like add 320
and 240 as a parameters of Rect , Here is
my code. Is this give me the result that i want. thanks
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, 320, 240); //
Apply QVGA dimensions
ByteArrayOutputStream output_stream =
newByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 30, output_stream);
byte[] byt=output_stream.toByteArray();
Thanks and Regards
umer
