How to save from rtspsrc to filesink?

[Giacomo D]

*Hi,
I'm trying to do a simple example to save a stream, by command line like
this:

- on the sender side, with VLC:*

cvlc v4l2:///dev/video0 :input-slave=alsa://hw:0,0 :v4l2-brightness=10
:v4l2-audio-volume=200 :file-caching=300
:sout='#transcode{vcodec=h264,width=320,height=240,fps=10,
vb=500,scale=0.5,acodec=aac,ab=128,channels=2,samplerate=44100,deinterlace}:rtp{mux=ts,port=8554,sdp=rtsp://127.0.0.1:8554/stream}'
:no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep 


*- on the receiver, with Gstreamer:*

gst-launch-1.0 mp4mux name=mux ! filesink location=/My_location/stream.mp4
uridecodebin uri=rtsp://127.0.0.1:8554/stream name=src src. ! queue !
mux.video_0 src. ! queue ! mux.audio_0 

*but it doesn't work!

So, on the receiving side I tried:*

gst-launch-1.0 --gst-debug-level=3 uridecodebin
uri=rtsp://127.0.0.1:8554/stream name=src ! queue ! theoraenc ! queue ! 
oggmux name=mux  src. ! queue ! audioconvert ! vorbisenc ! queue ! mux. mux.
! queue ! filesink location=/home/giacomo/streams_salvati/stream_oggi.ogg
*
I got a file which starts with a black video and the correct audio, after a
few of seconds I had the correct video+audio until on the debug file I got
this:*

Is there someone who can help me?
Thanks,
