--- Comment #1 from Matthew Waters (ystreet00) <ystreet00 at gmail.com> ---
Thanks for the report!

Unfortunately, it seems that you're not testing with the exact same frame sizes
which can impact the CPu performance.  E.g. videotestsrc will by default choose
a frame size of 320x240.  avfvideosrc most likely chose the highest frame size
supported by your camera/screen which may be 720p or higher.

Also, have you performed some profiling results that would point to a specific
place to look into for these performance issues?
