My Love for Ruby on Rails

Recently i implemented video uploads at S3 using ffmpeg-paperclip and ffmpeg where my uploaded videos get converted into mp4,webm and ogg(most required formats) along with 2 screenshots(with diff sizes) and stored at S3. its so wonderful in many ways:- your uploaded videos get converted into required formats(compatible on all browsers) before saving using ffmpeg through ffmpeg-paperclip moreover,you will also get screenshot(2 different images)of every video uploaded + AMAZON S3( you can even store locally,refer Paperclip ) if you want the background job to process video conversion then,use delayed_paperclip  i will show you how you can convert your uploaded videos into required formats and why we need to convert ....well refer  this .Before starting make sure that you have ffpmeg installed with all libraries needed,so click the above link instead of searching for how to install ffmpeg and install it( will take around 30mins.but its worthy ). Here i am using mediaelement.
