Jan, FYI, will assign you. Also note that openh264 should be also checked
now that it can write matrix too.
Also your nice fix from chroma sample location broke JPEG sample when you
go from 4:2:0 JPEG with thus center location to rgb h264 which is now
tagged as center but RGB cannot be center chroma, it does not have chroma.
4:4:4 may be affected too.
