How to run .mp4 videos on firefox
19 novembre 2015, par Haseeb AhmadWhen play mp4 videos on chrome it works fine.But same videos not playing on firefox. After some search I found this
Firefox does not support .mp4 playback. Try conveting the video to .ogg format which is fast becoming a standard format for html 5 applications.
Now how I convert this to ogg for firefox.
My model code ishas_attached_file :videod, :styles => {
:medium => { :geometry => "640x480", :format => 'mp4' },
:thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
}, :processors => [:ffmpeg]
validates_attachment_size :videod, :less_than => 100.megabytes
validates_attachment_presence :videod
validates_attachment_content_type :videod, :content_type => /\Avideo\/.*\Z/ -
