           Summary: rtpamrdepay make no playable stream

I got problem in rtpamrdepay element.
The jill.3gp is encoded in amrnb and h263 as a testing video file

gst-launch -v ffmux_3gp name=mux ! filesink location=/home/video/jill3.3gp \
{filesrc location=/home/video/jill.3gp ! qtdemux name=demuxer2 ! rtpamrpay !
rtpamrdepay !queue }! mux.audio_0 \
{filesrc location=/home/video/jill.3gp ! qtdemux name=demuxer ! ffdec_h263 !
ffenc_h263 bitrate=45000 rtp-payload-size=500 gop-size=3 me-method=4 ! queue }!
mux.video_0

In the above pipeline, after I converted the file into jill3.3gp(it runs
without error), it cannot be played through the following pipeline

gst-launch -v filesrc location=/home/video/jill3.3gp ! qtdemux name=demuxer \
demuxer.!queue! rtpamrpay ! udpsink host=172.20.122.9 port=11002 \
demuxer.!queue! rtph263pay ! udpsink host=172.20.122.9 port=11000

It gives out error like this:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /pipeline0/demuxer: This file contains no playable streams.
Additional debug info:
qtdemux.c(1444): gst_qtdemux_loop (): /pipeline0/demuxer:
no known streams found
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...


However, if i remove the rtpamrpay and rtpamrdepay in the converting pipeline,
the second pipeline runs smoothly without any problem, I can even see the movie
in the remote end

I suspect there is a problem within the rtpamrdepay(As I can use rtpamrpay
without problem in streaming the original file)
