Custom Webcam Recorder within a Browser

I need a custom built video webcam recorder that will fit into a Ruby on Rails web application. Function/requirements: 1. recognize any webcam that is connected into the user's PC or Mac running ie, firefox, chrome or safari. 2. By pushing record the video will be captured. When Stop is pushed the recording will play back automatically. If Record is pushed again it will erase the previous recording. When the save button is pushed, the local video file will be uploaded to our server. I would also like standard controls; volume, ff/rewind slide bar etc. 3. It is important that the recordings are high quality. If you bid, please give examples of previous work where you have done something similar. Also explain how you will address issues with recording quality.
