Description Sebastian Dröge (slomo) 2010-06-14 17:29:20 UTC 
gst-launch-0.10 videotestsrc ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)YUY2,width=640,height=480" ! videoscale method=1 ! "video/x-raw-yuv,width=640,height=531" ! ffmpegcolorspace ! ximagesink


This pipeline shows the behaviour. This only happens with the linear method and only appeared after the switch to orc

Happens for many other formats too, e.g. RGB, Y444, Y800, AYUV but not with Y16.

This also happens with the backup code, i.e. when compiling with DISABLE_ORC
