FFmpeg/libavcodec/libx265.c
Jan Ekström 9b2281a4a3 avcodec/libx265: add support for setting chroma sample location 
Unlike libx264, libx265 does not handle the chroma format check
on its own side, so in order to not write out values which are
supposed to be ignored according to the specification, we limit
the writing out of chroma sample location to 4:2:0 only.
