 Summary of the bug:
 How to reproduce:
 {{{
 https://yadi.sk/i/qBkjd3TzJ_yBQQ - matroska muxed file from blu-ray (749
 frames)
 % ffmpeg -color_primaries 1 -color_trc 1 -colorspace 1 -color_range 1 -i
 /home/ilya/eva/Evangelion1.11_test_.mkv -vf
 setparams=range=tv:color_primaries=bt709:color_trc=bt709:colorspace=bt709
 -ss 12 -frames:v 1 def_x264_ffmpeg.png

 ffplay -i /home/ilya/eva/Evangelion1.11_test_.mkv -ss 12

 Make screenshot from ffplay and compare. FFmpeg has worse picture,
 incorrect colors (see eyes for example), darker areas.

 ffmpeg version N-93394-g14eea7c47a
 built on Antergos Linux x86_64
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
