OpenShot Video Editor

Openshot does not find frei0r plugins

Asked by appzer0

Hello,

I am not sure if it is a bug so I post a question. Openshot does not find the frei0r-plugins though I did install them correctly. MLT was recompiled against frei0r-plugins too.

How can I see what openshot tries to do ? Terminal is desperatly silent; I got a simple window sayinf frei0r is unavailable. Libs for MLT are in /usr/lib64/mlt (libmltfrei0r.so
 is there, executable) and frei0r libs are in /usr/lib64/frei0r-1 . How do I debug this?

My distro is homemade so there may be something I do wrong but I just don't know how to find it out.

Try running this command (which comes with MLT):
$ melt -query "filters"

This is what OpenShot uses to determine what effects are installed.

Good point. Now I've recompiled mlt against frei0r, I did not check that melt output. I'm afraid I've got no trace of frei0r here:

$ melt -query "filters"

Thanks, I'm gonna investigate my MLT build, I'll create a new question if needed.

I have the Debian frei0r-plugins package installed. I just took a look, and that package installs all the frei0r libraries in /usr/lib/... for example:

/usr/lib/frei0r-1/RGB.so
/usr/lib/frei0r-1/addition.so
/usr/lib/frei0r-1/alphaatop.so
/usr/lib/frei0r-1/alphain.so
/usr/lib/frei0r-1/alphainjection.so
/usr/lib/frei0r-1/alphaout.so

Are your frei0r files in the same place?

Hi again and thanks for your replies,

My system is a homemade one. The important thing to know is that it is fully multilib : it has 32-bits libs (i686) in /usr/lib and x86_64 libs in /usr/lib64. The system is native x86_64 though (binaries, etc.).

I just saw by googling that the lib64 lib dir seems to be a problem. While most of the systems symlinks /usr/lib when thay have a /usr/lib64 lib dir, mine has two different ones.

See there: https://bugzilla.redhat.com/show_bug.cgi?id=456256#c6

So maybe I'd need a patch to recompile my frei0r, mlt and openshot packages. So I guess I should contact a frei0r dev, I'm afraid.

If you are curious, the git repo of my packages is here; http://git.tuxfamily.org/0linux/0linux.git?p=gitroot/0linux/0linux.git;a=tree
