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.
