Gstreamer RTSP to RTMP server

I’m going crazy cause Gstreamer is absolutely incomprensible.
Documentation doesn’t explain what are arguments and what is the correct sequence.
Only supply some examples and if what you need is not listed you are screwed.

I really don’t undestand why is used Gstreamer to access HW acceleration instead of FFMPEG.

Anyway, after this little personal outburst, someone knows how to read RTSP H264 packets, compress them in FLV without encoding and send them to a local RTMP?

PS FFMPEG equivalent:
ffmpeg -y -i “rtsp-source” -c:v copy -fflags flush_packets -fflags nobuffer -flags low_delay -tune zerolatency -an -f flv rtmp://localhost/live/camera1

Please refer to posts about RTSP and RTMP:

We are evaluating to support ffmpeg with hardware acceleration in future releases.
