I came across a topic "RTP stream video decoding" (http:// groups.google.com/group/android-developers/browse_thread/thread/ f963e8f7ac35b75b/481c181362eaa66c?show_docid=481c181362eaa66c#) on this forum.
Here I see a post stating: ------------------------------------------------------------------ Essentially it seems that at this stage the only way to get an RTP stream to work is a couple of hacks ------------------------------------------------------------------ Using this information, may I conclude that playing RTP live stream over RTSP is not supported by default? But Again a Google search tells me that many users are playing live stream from Wowza media server. Also there are notes suggesting that users are watching RTP live streams on their Android G1. Could anyone please clarify?
