Title: Twitch Streaming for Linux
Post by: johnbart on November 24, 2013, 11:21:53 am

I'm not sure if there are any other Linux users here but I got Mame streaming fairly decently on my laptop running Linux mint using the following bash script if it helps anyone else out.

-j
-----------------------------------

#! /bin/bash

FPS="30"                                                    # target FPS
QUAL="libx264-ipod640"                            # one of the many FFMPEG preset on (k)ubuntu found in /usr/share/ffmpeg

# Get Game Window
echo "Click, with the mouse, on the Window that you want to Stream"
rm -f twitch_tmp 2> /dev/null
xwininfo -stats >> twitch_tmp
TOPXY=$(cat twitch_tmp | awk 'FNR == 8 {print $4}')","$(cat twitch_tmp | awk 'FNR == 9 {print $4}')
INRES=$(cat twitch_tmp | awk 'FNR == 12 {print $2}')"x"$(cat twitch_tmp | awk 'FNR == 13 {$2=$2+0+10; print $2}')
rm -f twitch_tmp 2> /dev/null
echo " "

STREAM_KEY=<YourKeyHere>

ffmpeg -f x11grab -s "$INRES" -r "$FPS" -i :0.0+$TOPXY -f alsa -ac 2 -i pulse -vcodec libx264 -vpre "$QUAL" -crf 30 -x264opts keyint=50:min-keyint=20 -s $INRES -acodec libmp3lame -ar 22050 -threads 4 -qscale 5 -b 712000 -f flv "rtmp://live.justin.tv/app/$STREAM_KEY"

And people think getting everyday things to work in Linux is to much work...

As a trade off for the hard work getting things running in Linux you get a free pocket protector so it all works out :)

Nice.  Mind sharing the script for the webcam part?  I was going to start playing with things to make that happen too.

Right click. Add source. Pick camera. Grab corner of screen to resize. Click broadcast.

Ken, don't be jealous of the real computer men.  We'll let you join the dark side.  Just put down that old dusty floppy with Win98 on it we'll warmly welcome you :)

In the windows world we use flash drives now, and we dont even need scripts to get them accessible!
