It's just about bash syntax. The way you're using the " make bash
thinking you're passing test-launch a first argument like this:

( udpsrc port=5000 caps=

concatenated to:

application/x-rtp,

and a second argument like:

media=\(string\)video,

useless to say this is not what you should pass to the test-launch
command. I suggest you to try replacing the outmost pair of " with '
or the innermost ones with \"

Regards
