If your video (mp4, webm, ogg) does not play in the Yuvid player:
First, try pasting the video url directly in your browser's address bar. If the video does not play - the problem is with the video URL. The most common problem is that the video was not made public in your video hosting solution, such as Amazon S3. In that case you will get an "Access Denied" message in the browser.
If the video plays fine in the browser, clean your cached files in the browser's history, and re-paste the URL into the Yuvid configuration tool, (e.g. mp4 video URL into the "MP4 Source" field in Settings). Make sure there are no extra spaces. Save the video configuration.
