<br>* Requires both player and stream url to use HTTP or HTTPS. SSL can be configured on dedicated Wowza servers.
<p>Playback of live transcoded streams over HTTP requires packetizers available with <a href="http://www.videowhisper.com/?p=Wowza+Media+Server+Hosting">Wowza Hosting</a> and optimisations available with VideoWhisper plans.<br />
Due to HTTP based live streaming technology limitations, video can have several seconds latency and interruptions. Use a browser with flash support or mobile app for full experience including fast and reliable interactions based on RTMP.</p>
