ofxPhoto (libgphoto2)

This addon uses the gphoto2 library to take pictures remotely from your camera and use it directly in openFrameworks.

See http://www.openframeworks.cc/ and http://www.gphoto.org/ for more Information.

Is my camera supported

First check here if your camera is on this list: http://gphoto.org/doc/remote/ After this install gphoto2 for example (on ubuntu) with

sudo apt-get install gphoto2

and test if your camera works with this command

gphoto2 --capture-image-and-download

If this works for you, the addon should work too.

Install Instructions

Download the addon from here: http://github.com/benben/ofxPhoto/downloads Or fork it from here: http://github.com/benben/ofxPhoto Copy the addon in the addons folder and the example in your apps folder.

Mac notes (thanks to jesus gollonet)

The included libgphoto2 library doesn't work on mac. Don't add it to your project. You'll have to compile the library yourself and link from your project.

Here's how I've made it work using macports:

  • to compile libgphoto2 in 32 bit, you'll have to tell macports to compile for i386
  • open the file macports.conf (it's in /opt/local/etc/macports/ in my system)
  • uncomment the line that says

    build_arch i386

  • then install libgphoto2

    sudo port install libgphoto2

  • if everything went well, edit the file Project.xconfig in your Xcode project to be like this:

    OTHER_LDFLAGS = $(OF_CORE_LIBS) /opt/local/lib/libgphoto2.dylib

    HEADER_SEARCH_PATHS = $(OF_CORE_HEADERS) /opt/local/include/gphoto2

  • and you should be fine

Basic Usage

Plug in your camera and turn it on. A splash screen should appear where you have to unmount the camera from the system. If you get an "*** Error (-53: 'Could not claim the USB device') ***" on Mac, then run 'killall PTPCamera' to quit the daemon.

Launch the photoExample, press Spacebar and watch the Console. After a few seconds a picture should appear on the screen. If the addon doesn't work, but the gphoto2 capture command above, please report it.
