Convert videos to proper formats for HTML5 video on Linux shell using ffmpeg. Will probably convert this to a bash script later, but for the time being, here's some examples. Not sure there have actually sensible dimensions and bitrates for web video.
# webm
ffmpeg -i IN -f webm -vcodec libvpx -acodec libvorbis -ab 128000 -crf 22 -s 640x360 OUT.webm
# mp4
ffmpeg -i IN -acodec aac -strict experimental -ac 2 -ab 128k -vcodec libx264 -vpre slow -f mp4 -crf 22 -s 640x360 OUT.mp4
# ogg (if you want to support older Firefox)
ffmpeg2theora IN -o OUT.ogv -x 640 -y 360 --videoquality 5 --audioquality 0 --frontend

AdminAbility.new(user)
