We need a music search and downloading script that will work by fetching results through Youtube API. Fortunately, we have many existing sources to get inspirations from that you can utilize. This is a straight forward project, requiring a straight forward programmer. Interested programmers please contact via PM with your previous work sample of your scripts (the relevant, the better). We can then discuss about our complete requirements, sources and final price.
Im curious, are you saying download the Audio from a Video off youtube using API. or do you want the raw .flv Video downloaded?
