Hi there, I am working through this in a private discussion with another very helpful user. Essentially it seems that at this stage the only way to get an RTP stream to work is a couple of hacks:
A) Wrap it as an RTSP stream. Basically need a client/server architecture, perhaps another little service running in the background to buffer the RTP data (perhaps write to file?) and then respond to appropriate RTSP commands. I havn't tested this but theoretically it should work. B) Write the data to two files. For example each file contains 1 second of data. Write file, close file (thus the file gets timing information and lock is released) open the file with mediaplayer and play. Meanwhile open another file to write information to that. When mediaplayer finished with file 1, get it to play file 2. Meanwhile write information to file 1 again. And keep looping. This is horribly resource intensive, but should produce an okay video (so I hear). Although syncing information for this difficult (impossible?). That's for streaming in. If your looking for information about streaming out you should see the Sipdroid code VideoCamera.java where they implement a 'write to file', 'open file and stream' method. It produces a jerky but reasonable video quality. -- "The greatest challenge to any thinker is stating the problem in a way that will allow a solution" - Bertrand Russell Andy Savage Cell Phone: +852 936 34341 Skype ID: andy_savage Linked In: http://www.linkedin.com/in/andysavage On Tue, May 25, 2010 at 5:29 PM, Jez <jeremy.a.co...@baesystems.com> wrote: > Hi Andy, > > I have the same problem too - attempting to stream an axis encoded > live video stream as h264 format and using the media player to show > the video live on an Android phone. > > Now i'm not sure if this is possible? > > > On May 25, 2:45 am, Andy Savage <a...@bluewire.net.nz> wrote: > > Thanks for your suggestion. > > > > I had considered this.
