Sorry the right pipe is the following:
gst-launch-0.10 -e rtspsrc
location=rtsp://root:pass@192.168.2.127/mpeg4/media.amp ! rtpmp4vdepay !
mpeg4videoparse ! matroskamux ! filesink location=/tmp/test.mkv
and then playback with playbin or any stardard player
or
gst-launch-0.10 -e rtspsrc
location=rtsp://root:pass@192.168.2.127/mpeg4/media.amp ! rtpmp4vdepay !
mpeg4videoparse ! gdppay ! filesink location=/tmp/test.gdp
and then playback with
gst-launch-0.10 filesrc location=/tmp/test.gdp ! gdpdepay !
ffdec_mpeg4 ! xvimagesink
