VideoOutput shows blank screen and sound is off in multi-thread mode

It happens as long as you are not using the flag -DSINGLE_THREADED_PLAYBACK.

I tried running a video with a TV, pausing, adding a VideoOutput (with a ImageToTexture between). Then it doesn't crash but the VideoOutput image is blank (black) although it takes the proper width/size.

Sound playback is also flawed.

This is somehow related to issue #24.

Seems to be related to the multi-threading because if I add the flag -DSINGLE_THREADED_PLAYBACK in release mode it solves the issue.

When I run in multi-thread and disconnect video, the audio seems to be working. However as soon as I plug the video to an output the screen is blank and the audio stops working.
It must be an issue with OpenGL and threads (I have sound issues in single-threaded mode when I'm manipulating the GUI).

I've reintegrated the old Gear_VideoOutput to test it and it works fine, so there must be some issue with the OpenGL code in the new version of Gear_VideoOutput from Foogy.
