Android :: Streaming Encoded Video Via RTP

For a research project we need to capture video on the HTC magic and transmit this video over a network to other devices, both HTC magic's and desktop pc's (which have their own implementations of the codecs).For the transmission over the network we are using some of our own native libraries, which have all compiled fine and work. These libraries work via the RTP (Real time transfer) protocol. This poses a significant problem because RTP expects detailed information about the contents of each packet (exact timestamp, sampling rate, which part of which frame is in each packet etc.) So we tried the method described at http://www.mattakis.com /blog/kisg/20090708/broadcasting-video-with-an This appears the only way to get the MediaRecorder to send it's data to our native application. So we run a server-socket on the native side, send MediaRecorder output to a FileDescriptor of a javasocket. The native side does receive data. 2 problems however :

1. Like said in the blogpost : header information etc. is not filled in, so if we write the data to file from the native-side, it's not playable.

2. The socket we write to is TCP, so a stream implementation. So there is no clear way to know where each frame begins and ends (because the data comes in continuously). And that's the main problem : we can't package the data in good RTP packets for transmission! Nor can we get good information about the timing etc. So we looked into OpenCore a little bit, hoping to be able to do it through JNI-interfaces ourselves (or maybe even directly with the native implementations from our native code). This has proven a daunting task, because so little documentation can be found on these things. So the question is : Is it possible to get the encoded video (and audio) data with clear frame-separation and good timing-information for RTP transmission? (It is not an option to use anything but RTP, as the research is partly about RTP possibilities)
