Hello guys, I'm trying to install pd-extended in Ubuntu 20.04 without any success. Actually, I want to create a video mixer with simple effects for live performance and I read I need pd-extended with Gem. Is there another distro I should be using? I tried with the methods described on puredata.info but the PPA doesn't seem to be updatable.
Any suggestions?
Thanks for your time!

Forget pd-extended which is obsolete and not maintained since 2011...
Under Ubuntu, you can go for pd-vanilla and the last version of Gem which you can get with a simple "apt-get install Gem" I guess.

Then if you need simple and easy FX you can use Frei0r FX or freeframe FX for Gem... or go for glsl if you have the skill.

Thanks a lot for your help! I just install the last version of PD vanilla 0.52 and Gem via terminal like you suggested.
I try to follow this tutorial to create a simple video mixer : https://archive.flossmanuals.net/pure-data/video-gem-tutorials/video-mixer.html
but when I try to create an object "gemhead" or "gemwin" I get : could'nt create.

I went to help section and install Gem package but still can get it working...
What do I do wrong?
Really appreciate any help!

@PASY The GEM library is a single binary....... all the functions are in one executable rather than individual executables.
In Pd such a library needs to be loaded entirely as Pd starts up because Pd cannot find the individual parts by their names..
So a startup flag needs to be added to the preferences window.

In the Pd menu go to File..... Preferences....... Startup
and add -lib Gem as below (you don't need the other flags in my screenshot).......

If it still doesn't work then also add the full path from root for the Gem folder to File..... Preferences.... Path.

@whale-av THANKS A LOT I'm back to learning

or you can use the object [declare -lib Gem] in your patch so it will load Gem only when you need it in the current patch.

In recent version of Gem 0.94, [declare -lib Gem] should be already in the patch so you might not have last version maybe (which is already 3years old).
