Notice anything wrong with the video? No Sound? Don’t worry, it’s not a virus, nor your computer; but just the video itself.
YouTube may have found a way that could deter users from uploading copyrighted videos by just having the video muted instead of taking down the video as part of the law that makes up the Digital Millennium Copyright Act, also known as the DMCA.
YouTube has had technology that fingerprints audio tracks and matches it to a video and then notifies the user if the video is an copyright infringement. Also, it gave copyright owners to make some ad revenue off the content, or have it removed.
The notice reads:
This video contains an audio track that has not been authorized by all copyright holders. The audio has been disabled. More about copyright
Now, somebody has to find a way to defeat it.
