How to patch Ubuntu for Heartbleed

sudo apt-get update
sudo apt-get install -y libssl1.0.0 openssl
openssl version -a and confirm the "built on" date is >= 2014-04-07
sudo lsof -n | grep ssl | grep DEL and restart all listed services.

Repeat #4 until no results are returned.

compile ffmpeg for arm https://github.com/fiorix/ffmpeg-arm
create youtube 'live event'. get rtmp url + session id
run this:

raspivid -o - -t 0 -vf -hf -fps 30 -b 6000000 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/<SESSION>

you can tweak -b and -fps to your liking. the settings above work well for 1080p. by not specifying width or height we get the full 1920x1080 resolution from the raspi camera
