First thanxs 4 ur great work changing Tomgibara's code. I have tried to execute both, Webcambroadcaster and SocketCamera. I don't know if it's correct, my webcambroadcaster shows like someone's above:

RGB Format Found
Starting the player
Grabbing frames

And my socketcamera still shows that chess picture in instead of my webcam. What am I doing wrong? I noticed indeed Webcambroadcaster stops on:

socket = ss.accept();

I also create an entry on firewall 4 port 9889.

Thanxs in advance.

Hi!

I use ubuntu 10.10 and a Logitech Quickcam Express. The code is working fine. I just do not get a picture from the camera. I only get black with white noise. It's the same in JM studio. I guess this is a problem with my cam driver, or am i wrong???

Ubuntu 10.10 provides a driver, so i used it. Do i have to install an extra driver, or is it another problem.

Hello Neil,thanks a lot for this post....i got it working with a Frontech webcam on XP.
For the benefit of the readers,apart from the changes that u hv mentioned above,the following should be entered in the manifest file:

uses-permission android:name="android.permission.CAMERA"
uses-permission android:name="android.permission.INTERNET"

The first one is reqd when we are doing Camera.open() and the next one for the socket connection.
I had another problem in teh manifest file,that being a mismatch between the activity name,which should be CameraPreview if we are directly using your source files.
Thanks again...

2010-11-03T22:13:36.671-07:00

hi,
i can run the code successfully with any error,
however, the webcam image can't be shown in the emulator. 3 question i would like to ask:

1. how can i ensure the broadcaster is running successfully? i compile it and it shows the following:
RGB Format Found
Starting the player
Grabbing frames

2. do i need to run the JMStudio before i execute the broadcastor?

3. what IP address in the SocketCamera? i tried 10.0.0.2 (my computer's IP), 10.0.2.2 and 127.0.0.1, all don't work.

anyone can help? thanks!!

2010-10-10T05:50:46.074-07:00

Thanks a lot, it works for me and it's really useful.

I have also written the methods takePicture for SocketCamera. They are on my blog, but it's in italian, so if any english user is interested i paste methods here. (maybe not the best code but it works)

// Prova per takePicture
public final void takePicture(Camera.ShutterCallback shutter, Camera.PictureCallback raw, Camera.PictureCallback jpeg) {
takePicture(shutter, raw, null, jpeg);
}
public final void takePicture(Camera.ShutterCallback shutter,
Camera.PictureCallback raw, Camera.PictureCallback postview, Camera.PictureCallback jpeg) {
stopPreview();

try {
Socket socket = null;
try {
socket = new Socket();
socket.bind(null);
socket.setSoTimeout(SOCKET_TIMEOUT);
socket.connect(new InetSocketAddress(address, port), SOCKET_TIMEOUT);

if (shutter != null) shutter.onShutter();

// obtain the bitmap
InputStream in = socket.getInputStream();
Bitmap bitmap = BitmapFactory.decodeStream(in);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos); //bm is the bitmap object
byte[] b = baos.toByteArray();
// Chiama la callback
if (raw != null) raw.onPictureTaken(b, null);
if (postview != null) postview.onPictureTaken(b, null);
if (jpeg != null) jpeg.onPictureTaken(b, null);
} catch (RuntimeException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
socket.close();
} catch (IOException e)
/* ignore */
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
}
}

@Alejandro: i don't have your problems running this code, but :
1- If i remember right 127.0.0.1 it's the loopback address of the emulator and if u want to connect to your Computer u must use the explicit ip addres of computer or 10.0.2.2 (see networking under android emulator on android sdk pages)
2- IllegalAccesException point me to permissions of your Code, check the AndroidManifest if u have added permission for both CAMERA and INTERNET.
Elsewhere i can't help, sorry.

2010-10-06T03:46:07.659-07:00

Regards,

I am working with your code for the emulator to recognize the webcam on my computer and your camera to run applications from my computer as Layar. Working from the Eclipse IDE where I have an activity / application with your code and SurfaceWiew SocketCamera (which are 2 necessary as I understand).

Emitted from JMF with my cam RGB to IP 127.0.0.1 port 8888 which is the IP I set in the program.

Not what I'm doing wrong but when running the application gives me error: java.lang.RuntimeException and java.lang.IllegalAccesException.

Anyone can help me? Thanks.

2010-08-08T10:01:57.821-07:00

Don't forget that for the emulator it is necessary to have a proper internet address. In this case, since you are using the emulator in the same computer where the camera is connected to, you have to use "10.0.2.2" as your address.

2010-07-21T23:25:19.903-07:00

Hi Andy,

Had same problem of black screen but got it working.

Check that:
1)
Your Preview Class has the following (original) methods

public void surfaceDestroyed(SurfaceHolder holder) {
mCamera.stopPreview();
mCamera = null;
}

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
Camera.Parameters parameters = mCamera.getParameters();
parameters.setPreviewSize(w, h);
mCamera.setParameters(parameters);
mCamera.startPreview();
}

2) Your Manifest File contain CAMERA and INTERNET User permissions.
