QuickTime Frame Capture

[David Wikström]

In the ScriptMaster 4.11 sample file there was a function QuickTime Frame Capture which I no longer find in ScriptMaster 4.124.

I think I had this work in 4.11, but now it fails, whether I go back to the 4.11 plugin or use the current version. I just get the spinning wheel forever, not even an error message.

Does anyone have a clue about this? Anyone got a working webcam capture for ScriptMaster?

I'm using FileMaker Pro Advanced 11.0v4 on Mac OS X 10.6.8, with QuickTime Player 10.0 (128).

This requires the lti-civil jar, but seems to work

import java.awt.image.BufferedImage

import com.lti.civil.*

import com.lti.civil.awt.AWTImageConverter

import com.sun.image.codec.jpeg.*

factory = DefaultCaptureSystemFactorySingleton.instance()

try {

system = factory.createCaptureSystem()

} catch (Throwable e) {

return 'ERROR - no camera attached'

}

system.init()

info = system.getCaptureDeviceInfoList().get(0)

captureStream = system.openCaptureDeviceStream(info.getDeviceID())

count = 0

capturedImage = null

captureStream.setObserver({ sender, image ->

count++

if (count > 1) {

  capturedImage = image

  } //end if

} as CaptureObserver)

captureStream.setVideoFormat(captureStream.enumVideoFormats().get(0))

captureStream.start()

try {

Thread.sleep(2000)

} catch (InterruptedException e){

return

} // end try

while(! capturedImage) {

Thread.sleep(100)

} //end while

captureStream.stop()

captureStream.dispose()

system.dispose()

bimg = AWTImageConverter.toBufferedImage(capturedImage)

return bimg

Thanks for this John.

I added lit-civil.jar and I don't get any error message when I run this, but it doesn't actually work either. I get a garbled image-like thing in the container field. It looks exactly the same no matter what is actually in front of my webcam, so it's being generated in some other way...
