I tried to setup a livestream on Linux Mint 15.

INRES="1920x1080"
 #OUTRES="1024x640"
 OUTRES="480x270"
 FPS="25"
 QUAL="fast"
 
 API_KEY=my key is a secret :P
 
 ffmpeg -f x11grab -s "$INRES" -r "$FPS" -i :0.0+0,0 -f alsa -ac 2 -i pulse -vcodec libx264 -vpre "$QUAL" -s $OUTRES -acodec libmp3lame -ar 44100 -threads 2 -qscale 5 -b 712000 -f flv "rtmp://live.twitch.tv/app/$API_KEY"

It works with audio for the first few seconds and than it refuses to continue streaming (it stays at the same frame).

My upload rate is 23 kb/s – that’s bad, but it should be theoretically good enough.

Any idea how to solve this problem?
