hi,
I am getting frames from onPreviewFrame, compress to jpeg image
with YUV and send over the network,
but the problem is, i want to increase the frame rate. Now it is 4fps
but i want 15fps what can i do to increase frame rate, here is my
code
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);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 30, output_stream);
byte[] byt=output_stream.toByteArray();
try {
obj.writeObject(byt);
obj.flush();
// Log.d(TAG, "onPictureTaken - wrote bytes: " +
data.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
Preview.this.invalidate();
}
}
Thanks and Regards
umer
