ffmpeg | branch: master | Srinath K R <skr at nvidia.com> | Thu Jun  8 15:01:54 2017 +0530| [98ea98069b40c34aa7b762096f8f380012a7dd84] | committer: Luca Barbato

nvenc: Add default value for AVCodecContext::refs

AVCodecContext::refs is used to control the DPB size to be used by the
encoder. The default value for AVCodecContext::refs as set in
libavcodec/options_table.h is 1.

This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in
order to let the driver take the decision of the correct DPB size to use in
all cases.
