In theory, it would be possible an EGLDisplay *and* an EGLSurface, since 
rendering to an EGLSurface is already supported internally. It won't work with 
just an EGLSurface, unless you meant to use the default EGL display.

However, there are a bunch of missing bits for that to work:
1) The generic OpenGL video output is but a PoC; I never had time and 
motivation to complete it to production level.
2) A new plugin or an extension to the EGL plugin would be required.
3) A new libvlc API would be required.
4) I don't know the state of OpenGL ES support in VLC. I don't know how well 
EGL works in ES mode (since you mention rPI, I don't suppose you want to use 
desktop GL).
