[ffserver-user] Trying to live stream x264 video with FFserver

So how should I modify the ffmpeg command to add a container?

If I add "Format mp4" to the ffserver.conf file, that still doesn't fix it..
I think I understand what you're saying, but I'm not sure how to modify the
ffmpeg command to make this work:

The command I use right now is:

ffmpeg -f x11grab -r 25 -s 1920x1200 -i :0.0 -vcodec libx264 -vpre
lossless_ultrafast -threads 0 -s 640x480 http://localhost:8090/feed1.ffm
