How to live stream YouTube or Ustream from a raspberry pi.
I will put a link to the Image file when I get it set up on my website.
Just type the commands below. I did this all in PuTTY using SSH.
So what we need to do is cross compile FFMPEG for the Raspberry Pi. ( I will just put a Image on my website for people to just down load a working image if people want it.

sudo raspi-config
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get clean
First you need to install FFMPEG I used the website below.
http://www.jeffreythompson.org/blog/2014/11/13/installing-ffmpeg-for-raspberry-pi/

Installing FFMPEG for Raspberry Pi
INSTALL H264 SUPPORT
Run the following commands, one at a time.
1 cd /usr/src
2 git clone git://git.videolan.org/x264
3 cd x264
4 ./configure –host=arm-unknown-linux-gnueabi –enable-static –disable-opencl
5 make
6 sudo make install

1. INSTALL OTHER LIBRARIES/FORMATS
Anything else you would like to install should be done now, before compiling FFMPEG. This includes MP3, AAC, etc.

2. INSTALL FFMPEG
Add lines similar to the –enable-libx264 for anything else installed above. This may take a REALLY long time, so be patient.
1 cd /usr/src
2 git clone git://source.ffmpeg.org/ffmpeg.git
3 cd ffmpeg
4 sudo ./configure –arch=armel –target-os=linux –enable-gpl –enable-libx264 –enable-nonfree
5 make
6 sudo make install

Note if you have a Model B+ you can use make -j4 instead of just make to take advantage of all four cores!
