1st frame duplicated when HEVC decoding

Description

Hello,
I would like to report a strange behaviour when I decode a hevc elementary stream. Actually, the first frame is duplicated an I finally get a additional frame compare to the original file.
I already try to decode the same file with openHEVC and the HM decoder (v16.7) and I do not have this behaviour.
Below, how to reproduce:
encoding:

% ffmpeg -f rawvideo -s 1920x1080 -pix_fmt yuv420p -r 60 -i video_raw.yuv -vcodec libx265 -f hevc -b:v 5M video.265
ffmpeg version N-76224-ga7c5005 Copyright (c) 2000-2015 the FFmpeg developers
built with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu13)

decoding:

% ffmpeg -i video.265 output.yuv
ffmpeg version N-76224-ga7c5005 Copyright (c) 2000-2015 the FFmpeg developers
built with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu13)

thank you!

Gabriel
