Turning this gst-launch-1.0 command into a C++ app?

[Mert Can Ergun]

You don't have to read the whole manual but examining this code will give you
a great amount of idea about the framework and how to write basic
applications with it.

You can use videoconvert instead of autovideoconvert.

Video4Linux mounts different sources to different points, generally starting
from /dev/video0. And in your case you are telling the v4l2src to use the
source at /dev/video13. I am not 100% sure but if you don't set that
property, the element is supposed to search for valid sources on your system
and use the first one it finds.
