yep, codec_data is required along with the other rtp parameters. The easiest
way to make this work is to do the following sequence:

gst-launch -v filesrc location=~/data/sincity.mp4 ! qtdemux .video_00 !
rtpmp4gpay ! udpsink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
/pipeline0/rtpmp4gpay0.src: caps = application/x-rtp, media=(string)video,
payload=(int)96, clock-rate=(int)90000, encoding-name=(string)mpeg4-generic,
ssrc=(guint)915622229, clock-base=(guint)766539574, seqnum-base=(guint)24262,
streamtype=(int)4, profile-level-id=(int)1, mode=(string)generic,
config=(string)000001200086c5d4c307d314043c1463000001b25876694430303334,
sizelength=(int)13, indexlength=(int)3, indexdeltalength=(int)3
/pipeline0/rtpmp4gpay0.sink: caps = video/mpeg, mpegversion=(int)4,
systemstream=(boolean)false,
codec_data=(buffer)000001200086c5d4c307d314043c1463000001b25876694430303334,
width=(int)640, height=(int)480, framerate=(fraction)44100/1471
/pipeline0/udpsink0.sink: caps = application/x-rtp, media=(string)video,
payload=(int)96, clock-rate=(int)90000, encoding-name=(string)mpeg4-generic,
ssrc=(guint)915622229, clock-base=(guint)766539574, seqnum-base=(guint)24262,
streamtype=(int)4, profile-level-id=(int)1, mode=(string)generic,
config=(string)000001200086c5d4c307d314043c1463000001b25876694430303334,
sizelength=(int)13, indexlength=(int)3, indexdeltalength=(int)3
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

Then copy the rtp caps on udpsink and use them as caps on the receiving udpsrc,
like:

gst-launch -v udpsrc caps="application/x-rtp, media=(string)video,
payload=(int)96, clock-rate=(int)90000, encoding-name=(string)mpeg4-generic,
ssrc=(guint)915622229, clock-base=(guint)766539574, seqnum-base=(guint)24262,
streamtype=(int)4, profile-level-id=(int)1, mode=(string)generic,
config=(string)000001200086c5d4c307d314043c1463000001b25876694430303334,
sizelength=(int)13, indexlength=(int)3, indexdeltalength=(int)3" ! rtpmp4gdepay
 ! ffdec_mpeg4 ! xvimagesink sync=false

I did some fixes to gst-ffmpeg to not generate wrong timestamps. Above
pipelines work fine. Hope that helps, reopen if something is unclear.
