justin.tv.txt

This is how to get video working for justin.tv.txt on ubuntu 10.04.

Note: audio doesn't work
Note: some of this may be superfluous
Note: some may be missing, but I tried to trace my steps back.

1) Get rid of your current ffmpeg and x264

  sudo apt-get remove ffmpeg x264

2) install dependencies

  * sudo apt-get install libavcodec-extra-52
  * sudo apt-get install avconv
  * sudo apt-get libav-tools
  * sudo apt-get libxfixes-dev x11proto-fixes-dev

2) build x264
  
  * git clone git://git.videolan.org/x264.git x264
  * cd 264
  * ./configure --enable-static
  * make 
  * sudo make install

3) Build ffmpeg from source like so:
 
  * git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
  * cd ffmpeg
  * ./configure --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-pthreads --enable-libtheora --enable-libx264 --enable-x11grab --enable-libvorbis --enable-libmp3lame
  * make
  * sudo make install
  
4) make this script

  * wget https://raw.github.com/gist/4102798/justin.tv.sh -o justin.tv.sh
  * chmod a+x justin.tv.sh

5) * Update the scripts (justin.tv.sh) variables.

  * INRES # your screens resolution
  * OUTRES # in case you want to do some extra compression?
  * OFFSET # in case you have a second monitor?
  * FPS # I seem to max out at 24 fps, but 15 is healthy?
  * STREAM_KEY # this you can get from http://www.justin.tv/broadcast/adv_other

6) run the script!

  * `q` to exit.
  * ./justin.tv.sh
