Does this pipeline work from gst-launch-1.0.exe?

I suspect what happens is that this is gst_parse_launch() reporting a
syntax error in a rather confusing way.

The \"...\" bits surrounding the rtp caps are usually only needed when
using a shell to make sure it's all one single argument, but it's not
needed if you have a pipeline string.

Try removing these quotes from the string, and get rid of the spaces
after the commas.

Cheers
