[Ardev-users] problem with capture dc1394

[Alex K. <ak...@au...>]

Hi, I've come across the following problem. I'm able to run ARDev
once, but after termination, if I try to run it again I get the
errors:

	libdc1394 error: Failed to allocate iso bandwidth
	libdc1394 error: Failed to setup DMA capture
	Failed to setup capture

followed by a floating point exception. To overcome this I have to:

	modprobe -r -a video1394 raw1394 ohci1394 ieee1394
	modprobe -a video1394 raw1394 ohci1394 ieee1394

every time I want to run ARDev. My code is as follows:
    ...
    capture = new CaptureDC1394();
    capture->Initialise();
    ARCamera arcam("config/overhead.calib");
    camera = new CameraConstant(arcam);
    ARPosition arpos(arcam.Origin,arcam.Direction);
    camerapos = new PositionConstant(arpos);
    camerapos->Initialise();
    output = new OutputX11(capture,camera,camerapos,
                           OUT_WIDTH,OUT_HEIGHT,OUT_DISP_NAME,false);	
    ARDev::Start(output,AR_ENV);	
    ...

and the termination looks like:

    ARDev::Stop(AR_ENV);
    delete artkp_pre;
    delete artkp_pos;
    delete camera;
    delete camerapos;
    delete capture;
    delete output;

I suspect there might be something wrong with the way the capture
object is terminated.
