DLM for video capture [message #90668]

Dear Folks,

I've written a DLM that captures images from video cameras directly
into IDL. The library is available for download at

http://github.com/davidgrier/idlvideo

Video capture functionality is provided by OpenCV, the Open Source
Computer Vision library. The DLM and associated camera objects should
work for any camera that is supported by OpenCV. This package has
been tested with IDL 8.3 and IDL 8.4 running on linux and MacOS systems.

On my MacBook Pro, the following code snippet acquires and displays
3 seconds of 1280 x 720 RGB video images at 30 frames per second
using the built-in FaceTime camera:

cam = dgggrvideo()
im = image(cam.read())
for i = 0, 89 do im.putdata, cam.read()
obj_destroy, cam

Let me know if this is useful, and please do follow up with feature
requests and bug reports.

All the best,

David
