This is one of the cooler things! This is an embedded stream (from streamzilla). No more opening the native player. The player can also be controlled by javascript. This is SonyEricsson specific though... Works on Netfront > 3.3: change stream. For some MNOs this recuires a single APN or that the device can handle multiple open APNs.
The code:
<object type="video/3gpp" data="rtsp://qt3.streamzilla.jet-stream.nl/jet-stream/demostreams/goldfish_3GPv5_40K.3gp" id="player" width="176" height="150" autoplay="true"></object>
