[FFmpeg-user] Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

[RITESH MEHANDIRATTA]

Detailed description of the problem


i am a beginner in ffmpeg .i read the ffmpeg tool documentation
http://ffmpeg.org/ffmpeg.html .i i read encoder guideline
http://ffmpeg.org/trac/ffmpeg/wiki/x264EncodingGuide i have to rtp stream a
mp4 file.i write a command

ffmpeg -re -i sample.mp4 -c:v libx264 -c:a libfdk_aac -f rtp rtp://
127.0.0.1:1234 > 100011.sdp

what i am trying to accomplish is first encode audio and vidoe stream of
the file then stream using rtp protocol then generating corresponsing sdp
file and use this sdp file for receiving end (wowza media server).when i
use above command.i am getting error

Could not write header for output file #0 (incorrect codec parameters ?):
Invalid argument what should be the argument we have to provide for
encoding this mp4 file ?? please guideline !!

i read about vcodec they are used frequently without using parameters

an example in documentation is

ffmpeg -i INPUT -map 0 -c:v libx264 -c:a copy OUTPUT

where INPUT and OUTPUT are file names .please guide line and full response
by the command is

sample.mp4 -c:v libx264 -c:a libfdk_aac -f rtp rtp://127.0.0.1:1234 >
