The Best Formats To Use

The world really seems to be standardising on MP4 progressive downloads. It's the only format that will work on Android, iPhone, iPad, Win Mobile 7 (but not Nokia or Blackberries, unfortunately at the moment) and Facebook as well as all web browsers and is pretty much de facto for HTML5. Also, Google will reportedly only index videos in this format. So, there seems little point in encoding video in any format, or streaming them using rtmp or rtsp.
