Gstreamer: SHM pipeline for audio and video

Question

I have two shmsrc for audio and Video which sink in shmsink.

Pipeline: gst-launch-1.0 -v shmsrc socket-path=/tmp/pipe_v do_timestamp=true ! video/x-raw,format=BGRA,pixel-aspect-ratio=1/1,interlace-mode=progressive,width=720,height=576,framerate=25/1 ! queue ! videoconvert ! mux. shmsrc socket-path=/tmp/pipe_a do_timestamp=true ! queue ! audio/x-raw,rate=48000,format=S32LE,channels=2 ! audioconvert ! mux. matroskamux name=mux ! shmsink socket-path=/tmp/pipe_av shm-size=8100800 sync=false --gst-debug=3

Now See output on autovideosink & autoaudiosink:

Pipeline: gst-launch-1.0 shmsrc socket-path=/tmp/pipe_av do_timestamp=true ! decodebin name=demux ! videoconvert ! queue ! autovideosink sync=false demux. ! audioconvert ! queue ! pulsesink sync=false --gst-debug=3

I got warning:(1.) matroskamux matroska-mux.c:3685:gst_matroska_mux_write_data:mux:audio_0 Invalid buffer timestamp; dropping buffer (2.) pulse pulsesink.c:702:gst_pulsering_stream_underflow_cb: Got underflow

What else do I need to do to get this in working condition?
