Hi, I have a question that why do we need to do all the addFilter, setInitialFilters, setTerminalFilter steps? And we even need to addTarget for the filters in the group?
What's the difference between filters and initialFilters within GPUImageFilterGroup.m?
Is it possible that the GPUImageFilterGroup just receives a filters array, and setup setInitialFilters, setTerminalFilter, and even add target one by one for the filters being added?
