• Open the game that you want to stream and set window mode.

• Open a terminal, browse to the twitch script directory and run the script

    $ ./twitch.sh 
  

• If the avconv script gives you an error, use FFMPEG version. works exactly the same.

    $ ./twitch_ffmpeg.sh 
  

• Click with your Mouse on the game window

• Now you should be live (check on your channel).

• You can set the Audio settings (select the Null Output on pavucontrol)

• To stop the stream, click on the terminal and press CTRL+C

• BE CAREFUL ON SHOWING THE TERMINAL SINCE AVCONV/FFMPEG PRINTS ON THE TERMINAL THE KEY

• For suggestion or bugfix, please write to me on github. (I love suggestions! <3 )

• Please do NOT write for support on my BLOG. post bug reports on http://github.com/wargio/Twitch-Streamer-Linux !

Setup Audio (with pavucontrol):

• My microphone is Turtle BEach PLa Headset and my game is Syobon Action (Cat Mario)
• Open the game you want to stream and exec the script
• Now open pavucontrol
• Under Playback:
• Under Recording:
• Done (For ffmpeg/avconv setting, Monitor of MicAudio or Monitor of GameAudio. it's the same).
• If you don't see any Monitor of MicAudio or Monitor of GameAudio, but only Monitor of null output, use it, don't worry.

Dependencies:

    avconv pulseaudio alsa xwininfo pactl ffmpeg libavcodec-extra-53

###Suggested:
