Unfortunately documentation on how to write FFGL plugins seems to be scarce and usually very old. The little I know I had to learn by trial and error and by studying the FFGL source code.

If there's a quicker or better way I'll be happy to know.

hi friends,
is anybody interested in writing FFGL plugins with OpenFrameworks? If so you could give a try to an addon I wrote, ofxFFGLSpoutBridge (find it here on GitHub).

With this addon, together with the related FFGL-SpoutBridge plugin (included in this repo, in the FFGL-Plugin directory), it ...

I'm not sure what the problem is, but I suspect it could have something to do with the font loading code. Maybe the plugin does not find the file?

I suggest that you isolate the problem by commenting out most of the code and incrementally uncommenting it until you find where the problem is ...

PS the project is actually being built with VS2012, but the newer 2013 should be fine enough provided you set the compiler tool to version 2012 in project options for both the plugin project and the openframeworks library one (in solution explorer right click on each of them, select properties ...

Hi friends,
after spending a considerable amount of time trying to make a simple FFGL plugin with OpenFrameworks 080 and ofxFFGLplugin I believe I am almost there, but there still is something puzzling.

As you probably know I managed to modify the existing ofxFFGL code to make it work under OSX ...

Hi friends,
while working with the FFGL code I noticed that plugins can accept multiple input textures, and that the minimum and maximum number of inputs it is capable to deal with is given to the host during setup.

My question is: is Arena capable of passing more than one video input to the plugin ...

Ok this means that discarding every other frame is not going to do much harm... of course it will result in a frame rate of 30 fps and not 25 but it should be close enough.

thanks

OK, to make it work with windows you should modify the osx-only code at the beginning of setup() method, it is short and its purpouse is to change the current dir to the plugin data folder (in order to be able to load something from there if you need that, like the sample font).

You should also add ...

I have a question that may be comes from my ignorance of Arena, but I couldn't find a solution so I'm asking here. From what I can understand Arena converts all video materials to 60 fps before passing them to the plugins (likely because this is the refresh rate of final monitor output). But this ...

I improved a little my previous modifications of ofxFFGL (aimed to make it work wit OF 080), getting rid of the ugly "testApp" class (it is not ugly by itself but my way of using it was). Now there is one single class (pluginApp) that inherits from the original plugin and everything lives in there ...
