#413 pdp_ieee1394 on Mac refuses to release camera

[Hans-Christoph Steiner]

Using Pd-0.41.4-extended on Mac OS X 10.4 and 10.5.7/Intel using the built-in webcam on a 3rd gen MacBook Pro 17", [pdp_ieee1394] will open the webcam and get the data, but it will not release it. If you close the patch, the webcam remains open. You have to quit Pd to make it release the camera.

This means that you cannot open the webcam again from another patch once one patch has opened it. To reproduce:

1) open Help -> Browser -> examples -> pdp -> example13.pd
2) close example13.pd
3) open Help -> Browser -> examples -> pdp -> example14.pd
4) example14.pd can't get video from the camera
