I found that my kernel is3.4.112-sun8i(my board is H3) so I have to change parameters using FEX(/boot/script.bin), not config file as in mainline kernel.
But, I didn't found right parameters yet.

It think the problem is because screencapture programs capture X11 window, but vpdau output is not X11.
Screen capture mpv and mplayer with vpdau outputs it is not possible, on players places window area is black.
I tied with fbgrab and shutter.
What screen capturing program we have to use for vpdau outputs capture?
