Daniel,

You don’t need to do the linking to /Library/Plug-Ins/FxPlug/ since you’re working with PluginKit. I’d remove the link just to make sure it’s not causing any other issues.

Next, I would find your plug-in’s application in the Finder and double-click on it from the Finder to launch it. We have seen cases where Launch Services doesn’t notice the plug-in the first time it’s launched from Xcode. As such, it doesn’t register with PluginKit. Launching it by hand from the Finder seems to nudge Launch Services to where it recognizes the plug-in. Let me know if that works for you.

Hi everybody,

I try to create a generative plugin with FxPlugin. I am using FxPlug SDK 3.1.1 on OSX 10.12.4

First I create an empty FxPlug project with XCode (8.3.2). Then I change the base class to
@interface FilmstroFxPlugPlugIn : NSObject <FxGenerator>

and adapt the frameSetup removing RenderInfo, that the FxGenerator doesn't have:
- (BOOL)frameSetup:(FxRenderInfo)renderInfo
          hardware:(BOOL *)canRenderHardware
          software:(BOOL *)canRenderSoftware

and also the renderOutput removing the inputImage:
- (BOOL)renderOutput:(FxImage *)outputImage
            withInfo:(FxRenderInfo)renderInfo

For a start I commented everything out and return YES.

The project builds fine, no warnings (except the documentation inside the SDK).

Then I link from products the .fxplug into /Library/Plug-Ins/FxPlug/

But pluginkit doesn't show the plugin. pluginkit -a finishes without a message. But still pluginkit -m doesn't list the plugin.

I can run the Application as well, but it shows only an empty window, as I didn't implement anything there.

How can I troubleshoot, why it is not showing up?

N.B. I had a version showing up, but then I realised, that my changes didn't have any effect, so I removed all traces by hand.
Now I tried to start over, but now I don't even see an empty plugin.
I used XCodes "New FxPlug project", so the GUIDs should be unique.

Thanks for help,
Daniel
