Hi,
We're updating our plugins to offer native arm64 support in Final Cut Pro X and thus porting our existing code over to the FxPlug4 API.
Here's were we're running into issues:
Out plugin features a custom parameter (essentially a push button) that opens a configuration window on the UI thread. This window is supposed to display the frame at the current timeline cursor position. Since the FxTemporalImageAPI which we had been using before for that purpose has been deprecated, how could something like that be implemented?
We tried adding a hidden int slider parameter that gets incremented once our selector is hit in order to force a re-render and then grab the current frame in renderDestinationImage:... . However, the render pipeline seems to be stalled until our selector has exited so our force render mechanism seems to be ineffective. So how do we relieably filter out and grab the source image at the current time position in FxPlug 4 ?
Thanks!
Best, Ray
