ffmpeg 1 image (JPG) + 1 audio file (MP3) = 1 video (WEBM) using real encode (-re)

I'd like to make video streaming to distribute it in a streaming. The mp3 file is being extrated from a video file (witch is being recorded live) and, while audio being extracted (MP3), I want to take this audio file and a image it and spread it in a real time streaming. But -re is not working for this. To extract audio file i use:

ffmpeg.exe -re -i file(LIVE).AVI -vn -ar 22050 -ab 16k -r 1 -ac 1 -f mp3 C:\Users\" & wshNetwork.Username & "\Documents\audio.mp3"

This work very well to make the MP3 file. Using -re.

After that, I'm using this command to marge the auvio file with the jpg image:

ffmpeg.exe -loop 1 -f image2 -i c:\picture.jpg -re -i c:\Users\" & wshNetwork.Username & "\Documents\audio.mp3 -vb 10k -ar 22050 -ab 16k -ac 1 -r 1 -bufsize 300k -f webm www.adress.com

This second command is not working because the -re is not working, and produce a video with the picture and a choppy audio.

Can anybody help me?
