Description Yiliang Bao 2010-03-17 00:11:38 UTC 
Some columns at the right edge are not right, if we run the following pipeline.

gst-launch videotestsrc ! video/x-raw-yuv, width=320, height=240, format='(fourcc)YUY2' ! videoscale ! video/x-raw-yuv, width=640, height=480 ! xvimagesink

The boundary condition at the right edge is not handled properly in function vs_scanline_resample_linear_YUYV(), in file vs_scanline.c. 



Similar problem exists in function vs_scanline_resample_linear_UYVY().
