Registering frei0r plugin.

[Massimo Stella]

Yes, the reason why is blocked is that without the option to set an 
absolute reference position the effect is not usable inside kdenlive.

I've tried to use the standard keyframe ui via xml but I wasn't able to 
make it work but I'm not an actual coder.

The bgsubtract0r is parto of the:
"github.com/dyne/frei0r" code and you can find the specific effect in 
the "frei0r/src/filter/" folder after you have clone it.

I hope this can help.

Thanks in advance.

Massimo.

I am following this:
https://frei0r.dyne.org/codedoc/html/group__pluglocations.html

And melt can find it just fine. I think it is great that one can
install plugins locally. :-)

 From the same link:
"Kdenlive parses the effect folder at each startup, so that if you
have an XML file describing a new effect, just copy it to your
~/.kde/share/apps/kdenlive/effects/ folder and restart Kdenlive to
enable the new effect."

I have seen videos where people say that you have to install it system
wide. I have never tested locally, but I am very reluctant. :-)

This is really great news!

Is this the reason it is "blocked"?

I will try to fix it, then.
Does anyone know if the "keyframe" parameter has a working GUI?

Some 20 years ago, I would go with my own solution. I will try to fix
the bgsubtractor. I will try to figure which project it belongs to, so
I can clone the repo.
