gst-launch -v  rtspsrc location=rtsp://192.168.1.126:8554/mpeg4 latency=0 ! rtpmp4vdepay ! ffdec_mpeg4 !  ffmpegcolorspace ! fbdevsink

its working.

You should create two subchains (with queue elements), one for
video with the same chain that you used and another one for audio using
faad for advanced audio coding.  

To create a fork you give a name attribute and you can reuse the
element with the name + ".".  A queue element is recommended in all
fork branches.

All this gives us:

gst-launch -v \
rtspsrc location=rtsp://192.168.1.126:8554/mpeg4 latency=0 name=demux \
demux. ! queue ! rtpmp4vdepay ! ffdec_mpeg4 ! ffmpegcolorspace ! fbdevsink \
demux. ! queue ! rtpmp4adepay ! faad ! audioconvert ! alsasink

I am not able to test this but I just hope it helps.

Regards,

        Miguel
