Re: [Cin] ffmpeg 7.0 api changes

In CinGG compiled with ffmpeg7 I find "strange" behavior that I do not encounter with appimage (which has ffmpeg6). Using a greenscreen image, as the top track and any media as the background track, we need to apply the ChromaKey HSV plugin. We can see that the "Alpha Offset" slider does not produce any change. It does not work. If we repeat the same test with appimage, the slider works normally. Can you verify if this is also the case for you or does it depend on me or my system? I have also tried other plugins that use the alpha channel, and also patchbay overlays, but everything works fine.
