I also have encountered this "right band" issue when converting from YUV
to RGB. However, I noticed that issue doesn't appear when your frame
width is a multiple of 8. I assumed you mentioned HeightxWidth, not
widthxheight and, thus frame width is 240, which is a multiple of 8. In
that case this issue should not appear to my knowledge. I have post on
this in the same mailing list.
