title: How to use Elastic Transcoder in JAVA?
body: <p>I'm working a JAVA web project and upload media on S3 with liferay as backend. Now I want to transcode those videos with Elastic Transcoder and then stream them. I want to create a script that helps me process the videos from my project automatically rather than going to Elastic Transcoder console and then making a job every now or then.</p>
  
  <p>Can anyone tell me how to proceed on this?</p>
  
  <p>Also i was trying to add a prefix on the output file of Elastic Transcoder .. but when I Add Output Key it creates a directory instead of adding a prefix to the file.</p>
  
  <p>I want something like <strong>prefix-file-name.[media format]</strong></p>
  
  <p>Can anyone help regarding this?</p>
