Mobile social TV using cloud

I am interested for a code which will pull the video from exisiting cloud. also I need to use transcoding facilities from the cloud. The client is android app which will list the videos from cloud(may be amazon, google or intel or anything which provide EC2 and transcoding facility). The client will request for video which is on cloud the cloud will transcode it and send it to client. I need somebody who can write client (even if its not cloud that will do) and will give me web services implementation for using cloud services.
