The opaque struct contains the phycial address of video frame and some other information to make it possible to do the direct blending.Finally it comes to a zero copy. The early version of Samsung code use similiar strategy.

is decoded frame always converted and composed to RGB framebuffer in zero copy path?

I think most stick/STB products with RK3066 use 1280x720 framebuffer. then, any 1080p videos are downscaled to 720p for framebuffer, and lastly upscaled to 1080p for 1080p TV?

or 1920x1080 YUV framebuffer can be overlayed on top of 1280x720 RGB(UI) framebuffer?

(this question will be off-topic, but I want to know how "normal video player apps" works on RK3066 because I want to know difference between other apps and XBMC...)
