Hi Mark, 
sorry if I confused you
I have moved the thread to
 [FFmpeg-devel] [PATCH] lavc/amfenc: DXVA2 textures support implementation by AMF encoder
With the same code patch, but with different subject and with sample of usage.

I will fix code according your feedback and send the new patch there if you don’t mind
