This is probably not a problem with the caps, it means that your
GST_BUFFER_SIZE does not match the expected buffer size for this format
and width/height.  Usually this happens when you make different
assumptions about rowstride or plane offsets than GStreamer does
(rowstrides/padding/plane offsets are currently implicit in GStreamer).

For UYVY the size of the buffer should be

  GST_ROUND_UP_4 (width * 2) * height

and for RGB (bpp=24,depth=24) it should be

  GST_ROUND_UP_4 (width * 3) * height

if I'm not mistaken. Not sure about the gray format.
