RTSP live streaming from IP Camera

Is it possible to see the live stream of an IP camera using RTSP ?

Example URL: rtsp://public ip:554/1363e66e.mp4

The encoding is mp4 h.264 baseline profile at 320 x 240 resolution.

I followed the Wiki link here. But I get the error: Prefetch error -2

When I try to play using real player on the nokia e72, I get the error: 'General: System Error'.

Please let me know what I can do about this.

There are no video players on Ovi store that can play the stream either but I am able to play the stream on VLC on the desktop.

Which IP camera are you using? What resolution is it streaming at? Is there a username / password which is needed? Any firewall between the phone and camera? – Terence Eden
Resolution: 320 x 240. No password. No firewall. – Viraj
Can you stream any other RTSP sources? If not, itooks like there may be an issue with the E72 - discussions.europe.nokia.com/t5/Phone-Applications/… – Terence Eden
I can stream from youtube, but that is not live stream right ? But I have the same issue on Nokia C6-01 also. – Viraj
Try to make sure that both the container (MP4) as the codec, can be processed by the library classes of Java ME javax.microedition.media. – Lobo

You can stream it using ReaPlayer if you don't have VLC player in Ovi store. See the port address range supported by your IP camera. Try the range of 1024 - 2000. RTSP supports VLC, Quicktime and Real player. Using any of these objects you can stream it.

So I think here is the case,

There are a few different mp4 containers. Standard one wont allow you to wrap a real time data into a mp4 container because mp4 needs to have a field/atom in its header called MDAT and it has information about the file and its size as well.(which is written after the file is completely encoded. )

So unless you wake that you can not stream live stuff in mp4 UNLESS it is fragmented mp4.

Media Foundation will allow you to do this when windows 8 is out( i got the intel from the msdn forum so I dont know how true it is). I dont know what ffmpeg/Gstreamer is capable of. Again if this is a commercial product you are working on you might run into some licensing issues with ffmpeg.

Look at webrtc.

I am guessing best bet it to use webm or ogg/theora but I am not sure if theora can do what you want, This is something I am also working on.

Please share your findings

Thanks.
