[mythtv] DirectFB output for mythtv

I'm writing a videoout_directfb for mythtv, and it almost works. I think
maybe my inexperience with the internal formats in the NuppleVideoPlayer
(and with video formats in general) are the cause of my problems.
As I understand it, the player will call my:
methods for each frame. Is that right?
In ProcessFrame, do I need to do anything beyond:
process_video_filters(frame, &filterList, filterList.size());
In PrepareFrame, what is the format that I will get in the buffer? I
assumed it was YV12, same as DirectFB's YV12, but it appears not. (FYI
DFB YV12 is 8-bit Y plane followed by 8-bit 2x2 subsampled V,U planes.)
Any tips, pointers would be greatly appreciated.
Screenshot at http://hal.humberc.on.ca/~wilton/myth. Basically all I did
to get this was to memcpy onto a surface with YV12 pixelformat.
