I don't think you understand what domain knowledge means. If the civil engineer is a user of VLC, Youtube, etc. then they do not have "zero domain knowledge" when writing a transcoder. Not to mention that if they really are a great developer they'll just fork an open source project and be pretty much done. No matter who you are, the more virgin code you write yourself today, the more immature and vulnerable your application will be.
