            Bug ID: 765027
           Summary: critical warning in rtspsrc when doing srtp
    Classification: Platform
           Product: GStreamer
           Version: 1.8.0
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: aconchillo at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Problem is that default_srtcp_params only fills "srtcp-cipher" and "srtcp-auth"
in the caps. gst_mikey_message_new_from_caps requires srtp and srtcp both to be
filled.

Can easily test with:

gst-rtsp-server/examples/test-video (after defining WITH_AUTH and WITH_TLS).

And a client pipeline with:

gst-launch-1.0 rtspsrc location=rtsps://user:password@127.0.0.1:8554/test
tls-validation-flags=0 ! fakesink silent=false


These are the error:

** (gst-launch-1.0:10695): CRITICAL **: gst_rtsp_message_take_header: assertion
'value != NULL' failed

Program received signal SIGTRAP, Trace/breakpoint trap.
