How to use srtpdec with gstreamer on Android.

Hi, 

I use the following pipeline to receive a video stream: 
udpsrc port=5000 do-timestamp=true ! queue !
application/x-rtp,clock-rate=90000,payload=96 ! rtpjitterbuffer latency=100
do-lost=true ! rtph264depay ! h264parse !
video/x-h264,stream-format=byte-stream,alignment=nal ! queue ! appsink
name=appsink max-buffers=100 drop=true async=false (...)

What do I have to do to decode (unprotect) the videostream before processing
it any further? Just add srtpdec to the pipeline? But how to provide
information about the used encryption methode and key? gst-launch1.0 tells
me that srtpdec omits the signal "request-key" but how do I use such a
signal?

Thank in advance. Kind regards.
