here is the command :
ffmpeg -re -y \
-loglevel warning  \
-loglevel verbose \
-i rtp://239.0.12.1:5000 \
-bufsize 3000k \
-an \
-filter:v yadif \
-vbsf h264_mp4toannexb \
-maxrate 3000k \
-r 32 \
*-b 512k \*
-s:v 240x320 \
-vcodec libx264 \
-vsync 2 \
-pass 1 \
-f h264 -f rtp rtp://10.0.254.47:5000


In my case the error was  that bitrate was specified as 512000 but should be
512k. 

Now transcoding process has started, but I'm having the following output :
