- 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
note: it might work with libav-tools instead of ffmpeg (ffmpeg isnt on apt-get in raspbian) but I haven't tested it
