i stuck at the following error :

Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height

here is my configuration :

ffmpeg -re -y \
-loglevel warning  \
-loglevel verbose \
-i rtp:// \
-bufsize 3000k \
-an \
-filter:v yadif \
-vbsf h264_mp4toannexb \
-maxrate 3000k \
-r 32 \
-b:v 512 \
-s 240x320 \
-vcodec libx264 \
-vsync 2 \
-preset fast \
-preset baseline \
-f h264 -f rtp rtp://

I was also trying to play with all the parameters specified in error ,
taking in consideration that in x264 they should be divided by 16 , i was
switching rate parameter from 16 to 50 and so on , nothing doesn't change.
Also i was trying to configure different versions of ffmpeg, but still
getting such a type of errors.

Best regards, Vadim.
