Hi,

This patch has the implementation for supporting frame duplication (doubling/ 
tripling) by FFmpeg's HEVC decoder based on the picture_structre SEI value 
present in the encoded video.
picture_structure value of 7 implies doubling and 8 implies tripling. The value 
of picture_structure is set while encoding.

This addresses the requirement mentioned in the thread 
http://ffmpeg.org/pipermail/ffmpeg-devel/2019-June/245521.html

Thanks & Regards,
Praveen
