[PD] recursive video feedback in GEM or PDP?

[Ben Baker-Smith]

Thank you so much for that filter.

I was really struggling with figuring out how to utilize
[gemframebuffer] and this gives me a place to start.

Could this be incorporated into the [gemframebuffer] help patch?  That
help patch is seriously lacking.

Also, if someone could fill me/everyone in about what the
[pix_texture] second inlet is for, that would be fantastic.

Thanks again,
-Ben
