Can not change camera preview FPS

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use Processing 2.1 and add the latest Ketai library as of today (Dec. 27, 
2013).
2. Use the example CameraGettingStarted.
3. I am using Nexus 7 with Android version 4.4.2.

What is the expected output? What do you see instead?
I see the camera preview with no color distortion or other issues. My intention 
is to do real time preview as humanly possible. However, the video is delayed 
little bit. I am looking at the camera frame capture rate and the preview rate. 
However, when I try to change the FPS in 
cam = new KetaiCamera(this, 320, 240, 24);
to 24, 30 or even 15, I always get the same information on the console.
***********
Supported preview FPS: 5
Supported preview FPS: 8
Supported preview FPS: 10
Supported preview FPS: 15
Supported preview FPS: 20
Supported preview FPS: 24
Supported preview FPS: 25
Supported preview FPS: 30
calculated preview FPS: 5
Calculated camera parameters as (w,h,fps):320,240,24
Using preview format: 17
Preview size: 320x240,24
Photo size: 320x240
***********

What version of the product are you using? On what operating system?
Processing 2.1 with latest Ketai library on Windows 7. Android 4.4.2 running on 
Nexus 7.

Please provide any additional information below.

You've built a great library for novice hobbyists like me. Thanks!

Hello, sorry for the incomplete question. I always get "calculated preview FPS: 
5" and "Using preview format: 17", no matter what fps I use.
Thanks.

Yes, please! I have the same issue.. I have EXACTLY the same config, running on 
Android kitkat nexus 7. It certainly has a good memory(and processor), and the 
normal camera runs fine, but when I run any processor intensive task, like 
texturing or even face detection, it is really really slow(as soon as I turn it 
on)! making the process unfeasible to use.. Tried changing frameRate; not much 
luck there! But any suggestions for making the processing fast in any way? I 
plan to do to optical flow and hand detection..Thanks

The Android mode in Processing 2.1. does not work. Use Processing 2.0.3 instead

I do have the same problem using Processing 2.0.3 (as well as Processing 3a5). 
I am using a Oneplus One with Android 4.4.4.
