Couple of updates:
- I just tried this on Windows and rendering video works with ofDisableArbText().
- I digged through ofAVFoundationPlayer and noticed that the texture target is only set in the iOS version of the texture cache.
- A quick Google search seems to indicate that it's not possible to do this on desktop without rendering to a new texture: http://stackoverflow.com/questions/13933503/core-video-pixel-buffers-as-gl-texture-2d
