VLC and RTSP for live streaming

[Giacomo D]

Hi everyone,
I'm trying to use VLC to stream my live camera, enabling "Activate
Transcoding" option (MP4=Video h264+ MP3).
This is the output string with VLC (I have no experience with it):
:sout=#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://:8554/dd}
:sout-all :sout-keep

On the receiving side I'm using a Gstreamer pipeline like this:

   self.pipelinelaunch=Gst.parse_launch(" rtspsrc
location=rtsp://127.0.0.1:8554/stream  \
          ! queue ! rtph264depay ! h264parse ! queue ! decodebin ! queue !
videoconvert ! queue ! autovideosink \
   rtspsrc location=rtsp://127.0.0.1:8554/stream    ! queue ! rtpmp4gdepay !
aacparse  ! \
          avdec_aac ! queue ! decodebin ! queue ! audioconvert !
audioresample ! queue ! autoaudiosink ")

If I try cutting the second part of the pipeline (that for the audio) I'm
able to receive the video. If I add the audio part I get a video freeze.

For .AVI/.mp4 files, that pipeline works fine (Disabling "Activate
Transcoding" in VLC).

Is there someone who can explain to me what I am doing to wrong? Is there
someone who has experience with it?

Thanks.
G.
