about Xvideo support in glamor

[bradpitt]

I want to ask some questions about Xvideo.  1. What is the difference between overlay video and textured video adaptor？
2. xf86-video-intel has implemented overlay video adaptor and textured video adaptor. If I want to add Xvideo adaptor in glamor, which should I use? can I implement putvideo function with I965DisplayVideoTextured() and intel_display_overlay() in glamor?
