I am trying to setup a pipeline that takes a rtp pcap file as input, which
contains mpeg4-generic audio and convert it to mp4 format, using pcaparse,
rtpmp4adepay and qtmux plugins

Following is the pipeline

gst-launch filesrc location=audio.rtp.pcap ! pcapparse ! "application/x-rtp,
payload=96, clock-rate=30" ! rtpmp4adepay ! qtmux ! filesink location=out

I get the below error when I run the pipeline

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstQTMux:qtmux0: Internal GStreamer
error: negotiation problem.  Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info:
gstqtmux.c(1815): gst_qt_mux_add_buffer ():

format wasn't negotiated before buffer flow on pad audio_00
Execution ended after 323000 ns.
Setting pipeline to PAUSED ...

Can you let me know the fix for the problem

Thanks
