Hi all!

Instead of using a capturing card at the server, I was thinking of taking
the picture remotely and transfer it to the server for processing. Since I
dont have a capturing card installed at the server, I'm not able to test the
examples that are included when installed, so I'm in need of some help.
*What type of encoding of the picture are allowed?
*Any example of function calls for using files instead of capturing card?
*Has anyone done this before and might be willing to share some thoughts?

All ideas are welcome!

Best to you all

Why would you want to do that. The frame-rate would be horrible I think.
Another solution you should consider is using OpenTracker. With
OpenTracker the images are processed by the machine grabbing the images
and the calculated coordinates can be multicasted of the network.

Hi,

>*What type of encoding of the picture are allowed?

Raw image data.
Pixel format is defined in 'include/AR/config.h'.

AR_PIX_FORMAT_ABGR
AR_PIX_FORMAT_BGRA
AR_PIX_FORMAT_RGBA
AR_PIX_FORMAT_BGR
AR_PIX_FORMAT_RGB

These pixel formats would be available.


>*Any example of function calls for using files instead of capturing card?

I do not know.

If you make fonctions below, it would be perfect.

int        arVideoOpen( char *config );
 Open a video device. --> Open a image file or a network port.

int        arVideoClose( void );
 Close everything on video handling. 

int        arVideoDispOption( void );
 not needed. Null function is OK.

int        arVideoInqSize( int *x, int *y );
 return the image size.

ARUint8   *arVideoGetImage( void );
 return the pointer for captured image.

int        arVideoCapStart( void );
 Activate image capturing. So not needed for some setups.

int        arVideoCapStop( void );
 Deactivate image capturing. So not needed for some setups.

int        arVideoCapNext( void );
 Getting ready for capturing a next image.
 Not needed for almost setups.
