Frank Barchard ae55e41851 use rounding in scaledown by 2 ... When scaling down by 2 the formula should round consistently. (a+b+c+d+2)/4 The C version did but the SSE2 version was doing 2 averages. avg(avg(a,b),avg(c,d)) This change uses a sum, then rounds.

libyuv.h	Remove bayer format support from libyuv. This format is very rare and used on legacy hardware. Its not well optimized and has bugs related to odd widths. Removing the format will allow tests to pass under more circumstances, run faster and allow focus on higher priority quality and performance issues.	2015-02-09 19:58:19 +00:00
