[Bug 794400] rtspclientsink: Issues with Wowza when using v4l2h264enc on Dragonboard 410c

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=794400

--- Comment #6 from Rob Gries <rob.gries at egwtech.com> ---
@Nicolas Dufresne: I was able to get 1.13 to compile via a new Yocto recipe
that I've dropped into my build, but this does not seem to make a difference,
even with the added h264parse element between v4l2h264enc and the rtspclient
sink element.

I'm still working on getting the 1.14 rc2 version to build via bitbake and will
continue on it and report back when I make any meaningful progress.

My new log is below:
