ofxImageSequenceRecorder on OSX with v0.8.3

x-code
#1

I’m getting all kinds of errors when trying to build the ofxImageSequenceRecorder example on OSX with openFrameworks v0.8.3. Is this addon simply not supported for v0.8.0 and up? The ofxAddons site suggests its working with ~0.8.0 and Ive seen some recent GitHub activities and pull requests. I’m currently using mosboston’s fork, as it looks the newest. If there are no new versions, what would be the quickest fix or work around to save a sequence of ofImages to a movie file?

Thanks!

Here are the errors that I am getting

did you link coreVideo framework

I simply ran the example that was in the cloned directory. What core library needs to be linked? Would I just add it to the header search paths of the project?

#4

Click on the project in the Navigator, the go to buildPhases->link with binary Libraries -> click the plus sign -> add coreVideo.framework. The header search path should be included automatically.

93% of the time linking problems in addons in Xcode can be fixed by regenerating the project files using project generator. Stuff changes a lot in the core and some addons don’t keep their project files up to date.

Alternatively build it with the makefile system. :smile:

Adding the Makefiles did the trick! With the core project generator, is it a viable working method to overwrite a current project to update its .xcodeproj but maintain the source files?
