it might be a misuse of the headers from your system and the FFMpeg folder. It is not using the headers from the FFMpeg include folder. I used a toolbox and installed the ffmpeg vulkan decode branch to /usr/local/ and then built Granite in the toolbox. You can also build and install FFMPEG to your /usr/local on your machine.
