*Hi Everyone,* This problem is *really* bugging me. It's a lot bigger than a few of us not being able to receive RTP.
It's the fact that Android currently *does not support incoming real time streaming*! This is a *huge* problem for a new platform that wants to really become the device people buy. Real time video streaming is a huge industry... what a big oversight??!! I've posted a bug report<http://code.google.com/p/android/issues/detail?id=8959&q=rtp&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars> but I don't expect it to get fixed anytime soon as nobody has posted any comments or even starred it. However, there is an upside many people say that the beauty about open-source is that you can fix it yourself. Sadly I'm not a C-coder and would spend months just learning it. So, is anybody able to help me with the required patches to OpenCore? I am sure for somebody with some experience then it shouldn't be a big deal (I see that RTP is supported using RTSP so to pass in a native RTP stream or to support SDP's from SIP shouldn't be too hard I guess). In the meantime I have been working to overcome this problem, I've attempted a solution running FFMpeg & FFServer on the phone itself to stream out RTSP (no transcoding just streaming). My plan was to use this to stream to the video to the local MediaPlayer... Unfortunately the RTSP playing code is very picky on Android. It wouldn't play the stream. However I have successfully gotten VLC to play the stream from the phone (although this doesn't help me so much), so I know it works. I'm a bit stuck on what to try next! Any ideas would be appreciated.
