I want to streaming RTMP signal to RTP(multicast, mpegts container) via GStreamer. As I understand, I need to perform the following actions (please correct me if I wrong):

  1. Demuxing RTMP stream
  2. Muxing tracks to MPEGTS
  3. Streaming data into RTP

I can perform it via FFmpeg:

ffmpeg -i rtmp://184.72.239.149/vod/mp4:bigbuckbunny_750.mp4 \
       -c copy -f rtp_mpegts rtp://127.0.0.1:10001

I need to achive the same results via GStreamer and I've tried the next command:

gst-launch-1.0 -v rtmpsrc \
           location=rtmp://184.72.239.149/vod/mp4:bigbuckbunny_750.mp4 \
           ! flvdemux ! h264parse ! rtph264pay \
           ! udpsink host=127.0.0.1 port=10001

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstRTMPSrc:rtmpsrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstRTMPSrc:rtmpsrc0:

ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
/GstPipeline:pipeline0/GstFlvDemux:flvdemux0.GstPad:audio: caps = "NULL"

Please help figure out with. What is the correct command to streaming RTMP to RTP without transcoding via GStreamer?
