Hi,
currently the NV12/NV21 produced by videotestsrc seems to be wrong or the
conversions in ffmpegcolorspace:

gst-launch-0.10 -v videotestsrc !
"video/x-raw-yuv,width=320,height=240,format=(fourcc)NV12" ! ffmpegcolorspace !
"video/x-raw-rgb,bpp=32,depth=24" ! ximagesink

This shows wrong colors at the borders of the various colored bars. The strides
used by both elements are the same and I think it's videotestsrc's fault here:
