EDIT : did some tries, still same problem, but i have a more recent log, hope you'll be able to help me :/

Hello everyone :) ! So 'im kinda happy to see an all-in-one broadcaster software getting easy access on Ubuntu, and so i tried it out, but i have a problem to record/stream :

- i created a scene and added sources, i also changed the priority of sources so i know what is on top of what

- i changed some of the settings (log below), i don't know how to use ffmpeg so i use the default output.

- i also sought for a topic here about that problem and changed some settings according to what was told, sadly it didn't changed anything :(.

- when i launch a record/stream, i can hear the sound of my game, but i can't see anything but pitch black on the screen (although, on the preview, i can see them all).

My graphic card is : Gallium 0.4 on NVD9

you need to add an Image as a source, I don't see that in your posted log file. Your mesa and opengl library is really old as well.
it says:
16:36:13: OpenGL version: 3.3 (Core Profile) Mesa 10.1.3

Oh yeah, do you know where i can update OpenGL for the best version : > ? Or should i just get the first update i see ?
Also, i didn't specified it in my message, but i did a lot of tests, including one adding an image as a source, adding and Xcomposite source, etc... Everything led to the same conclusion : sound but black screen :( ! I also did exactly what Osirez showed in his installation tutorial, and it didn't worked for me either.

You can try to add the xorg-edgers PPA to your PPA list & make an update: the PPA warns you about its potential instability but that could be an improvement ;)

i use that ppa but i will warn you that i've heard other's complain about it their GUI breaking after they enabled that ppa. after you enable the ppa you'll have to
Code: 
sudo apt-get update
Code: 
sudo apt-get dist-upgrade
and then look for a lot of mesa packages to be updating and you'll know that you enabled the ppa correctly
