I had a problem when trying to send muxed video(h264)+audio(mp3) using MPEG TS
container through network via RTP+UDP.

The sender was a custom board with LTIB Linux from Freescale. The receiver was
a PC with Ubuntu 9.04 .

The sender command:
gst-launch -vvv mfw_v4lsrc capture-width=320 capture-height=240 !
mfw_vpuencoder codec-type=std_avc bitrate=600 ! mux. alsasrc ! queue !
audioconvert ! mfw_mp3encoder !mux. ffmux_mpegts name=mux ! rtpmp2tpay !
udpsink host=192.168.10.84 port=5555

The receiver command:
gst-launch -vvv udpsrc port=5555 ! queue ! rtpmp2tdepay ! ffdemux_mpegts
name=demux ! ffdec_h264 ! xvimagesink demux. ! queue ! mad ! alsasink


The error message on receiver:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstRtpMP2TDepay:rtpmp2tdepay0:
Internal GStreamer error: negotiation problem.  Please file a bug at

Additional debug info:

--------------------------------------

After that, I tried a PC-PC transmission on the same machine using localhost.
The same error message was given.

The 2nd sender command:gst-launch -vvv v4l2src ! x264enc ! mux. alsasrc ! queue
! audioconvert ! lamemp3enc ! mux. ffmux_mpegts name=mux ! rtpmp2tpay ! udpsink
host=192.168.10.84 port=5555

The 2nd receiver command remains the same.
