I'm attempted to stream an already recorded video file to twitch servers using FFMPEG but I only get audio so far no video. I've tried several settings, and different files (avi,etc) but I still get audio only. Here is my FFMPEG settings:

 ffmpeg -re -i test.mp4  -vcodec libx264 -preset fast -crf 30 -acodec aac -ab 128k -ar 44100 -strict experimental -f flv rtmp://live-dfw.twitch.tv/app/"TWITCHKEY"

Has anyone nailed this? I'm using ffmpeg 0.8.17-6:0.8.17-1 under Ubuntu.
