MP4 file from MPEG-2 PS

[AniketH]

Hi,
I'm having difficulty to generate an MP4 file from an RTP stream. I've
written a customised plugin which depayloads MPEG2 PS stream from RTP
packets. Further I'm using mpegpsdemux to get video and then trying to
decode and save it. When I save the dump directly from demuxer, I get a
playable video but without any picture. So I though I need to decode it
properly but the video generated is corrupted. Following is my pipeline:

gst-launch-1.0 -e udpsrc address=x.x.x.x port=xxxx
caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)MP2P"
! rtpbin name=recv_rtp ! rtpmp2pdepay ! mpegpsdemux name=demux
demux.video_e0 ! mpegvideoparse ! mpeg2dec ! videoconvert ! deinterlace !
videoconvert' ! video/x-raw ! openh264enc ! h264parse !
video/x-h264,stream-format=avc ! mp4mux ! filesink location=./stream.mp4

I can confim that data is resolved and sent ahead by the demuxer. The
decoder seems to be receiving continuous frames. *Attaching an instance of
