Hi, i need advice on the following topic:

I'm using mlt-0.9.2 on Centos 7 Linux and i can play very well all kinds 
of videos when i launch the player from the desktop gnome-terminal.

Now, i'm developing a python script that runs inside Autodesk's Maya and 
i'm trying to launch the video player using the subprocess.call method.

And here is where i bump into a problem: a gnome-terminal opens up and 
gives the following error:

mlt_repository_init: failed to dlopen /usr/lib64/mlt/libmltavformat.so
   (/lib64/libavfilter.so.4: symbol sws_isSupportedEndiannessConversion, 
version LIBSWSCALE_2 not defined in file libswscale.so.2 with link time 
reference)
No LADSPA plugins were found!

I think the problem is that the gnome-terminal's config is not correct. 
In the same terminal, only if i login as root and do a "ldconfig" i can 
then do "melt <whatever>.mov" and the player works...

I've tried to add the user and the ldconfig command to the sudoers list 
with no result.

Can you give me a hint on this please?

My system is:

Centos 7
mlt-0.9.2 (i tried latest mlt-0.9.6 but compiled unsuccessfully on my 
machine)
python 2.7
Maya2015 sp6

Many thanks in advance!
