There wasn\u2019t a whole lot of information about it around but I managed to piece together a quick script to do live streaming from a linux desktop.\u00a0 It\u2019s simple and for speed reasons I\u2019m not broadcasting sound myself. (I get unrealiable levels of upload lag so if i add sound it\u2019s kinda distorted\u2026I really wish their streams allowed speex codec :\/)<\/p>\n

if you do want sound, you can change it to this for alsa<\/p>\n

ffmpeg -f x11grab -s $SIZE -r $FRAMERATE -i :0.0 -f alsa -ac 2 -i hw:0,0 -vb $BITRATE -vcodec libx264 -threads 0 -acodec libmp3lame -ab 128k -ar 22050 -f flv \u201crtmp:\/\/live.justin.tv\/app\/$KEY\u201d<\/div>\n

or for OSS<\/p>\n
