The CVideoPlayerUtility::OpenUrlL method supports Real Time Streaming Protocol (RTSP) for streaming video content. For more information on CVideoPlayerUtility, see Playing a video clip.
Alternatively, use MDFDevVideo Record API and MDFDevVideo Playback API to build an application that records and playbacks video stream. These APIs are available in the Extensions Plug-in for S60 3rd Edition SDK for Symbian OS, Feature Pack 2, v1.2. Note that these APIs offer low level access to codecs, and the codecs used in different 3rd Edition devices may vary.
Another alternative is to use the Media Recorder API to record audio and video stream from the camera. This API is available in the SDK API plugin. For video playback, use the MDFDevVideo Playback API. For audio playback, use CMMFDevSound or CMdaAudioOutputStream class.
