Streaming on Nokia N95

[mar1r]

I'm trying to stream a video to a Nokia N95.
I've set up VLC as a VOD server using:

Code: Select all

vlc -vvv -I telnet --rtsp-host 0.0.0.0:5554 telnet 192.168.2.23 4212 > new 10011212592200 vod enabled > setup 10011212592200 input /test.mpg > setup 10011212592200 output #transcode{vcodec=mp4v,vb=250,scale=1,width=320,height=240}

on the N95, i launch rtsp://192.168.2.23:5554/10011212592200
and only get the following. When I launch it using vlc on another PC, it works perfectly.

Code: Select all

The communication stops here. The Nokia doesn't send a second SETUP request for the video track and just reports an error.

Can anyone help?

Does the server start sending any RTP, and to the right destination?

[mar1r]

No, the server just waits for the other setup request for trackID 1. No RTP is sent. Actually, the client shuts down the TCP connection.

[Rémi Denis-Courmont]

Well that's actually right. The server should not send anything until the client sends a PLAY. So stalling comes from the client.

As far as I can tell, the client fails because the Transport field in the response is incomplete. At least the unicast and server_port values are missing.

[mar1r]

But the exact same stream works perfectly on another computer running VLC as the client.

Am I doing anything wrong setting up the VOD server?

[Rémi Denis-Courmont]

The N95 RTSP client is less tolerant.
