Hi all

I am working on a software that performs live streaming of h264.

I encode using x264 and decode using libav.

this all work fine until i enable hardware acceleration.

when decoding the frame, i will receive the message "Missing reference 
and the output will be only the upper left quarter of the image.

switching between dxva and opendecode doesn't seem to make a difference

any information would be appreciated.
