rtspclientsink already includes payloaders so you don't need a
rtph264pay there.

What you're missing is that the name of the elements need to match a
specific format. i.e. the depayloader in your test-record command line
needs to be named 'depay0'.  You also may need to modify the test-record
example to send an EOS on shutdown so that mp4 headers are finalized
correctly as the resulting fiel will not really be playable as-is. 
Another option is to attempt to attempt enable robust-muxing mode.
