If you're using gst-launch (if not, then reproduce the issue with gst-launch),
run with GST_DEBUG_DUMP_DOT_DIR=/tmp, then install dot (from the graphviz
package), then run:
dot -Tpng -o /tmp/gst-launch.png /tmp/$file
with $file being one of the files generated by gst-launch, which will have the
string "PAUSED_READY" in it, and ending in "dot".
The look at it in an image viewer, and check if there are colorspace conversion
elements, and what they convert from and to. It may be that there are
unnecessary conversions that slow down the pipeline.

Also check that the gst pipeline and manufacturer sample code use the same
framerate for each resolution.
