[SDL] Select X11 Display

[Enrique Terleira]

Hello,

I have a problem with SDL I hope you can help me out with.

I have followed this tutorial (http://www.dranger.com/ffmpeg/) and 
results are perfect.

My problem is that I need to play 7 different movies in 7 different 
displays (x-displays in X11), and I don't know how can I do it, since I 
haven found any SDL function that enables you to select the display.

If I could do it, I could, for example, have seven different threads and 
each one operating in a different display.

I have been reading about OpenGL and SDL integration, since with GLX you 
can select a glxcontext ¿and attach it to a thread?, but I don't know 
exactly how must I do it.

Any help will be of much help.
