VLC

Hi all!

I am trying to use VLC as rtsp server to use with app_rtsp.
The Stream is accessible by VLC from other machines within
the network 
but asterisk says:

 -- Executing [vlcfrom-sip:3]
rtsp("SIP/thomas-0842d668", 
"rtsp://192.168.160.29:5554/myStream") in new
stack
[Jan 16 11:41:49] WARNING[5376]: app_rtsp.c:1032 rtsp_play:

[Jan 16 11:41:50] WARNING[5376]: app_rtsp.c:1531 rtsp_play:

<rtsp_play    -- Executing [vlcfrom-sip:4]

Did anyone get that running? How?

Greetings,
Thomas Frieling

BTW: This is how I do it:
$ vlc --ttl 12 -vvv --color -I telnet --telnet-password
videolan 
--rtsp-host 192.168.16.29:5554
$ telnet localhost 4212 #password is 'videolan'
 > new myStream vod enabled
 > setup myStream input myVideo.mp4

The URL is
rtsp://192.168.16.29:5554/myStream

Hi Klaus!

The audio codec used in the file is AMR... The SIP phone
expects PCMU 
but normally this is not the problem. At least when
streaming the file 
with the Helix StreamingServer at least video works.

Do you use the VLC?

Then I guess AMR codec is already installed. MAybe the
problem is in the 
session setup and VLC server reports different audio codec
in SDP then 
Helix does.

Compare SDP during setup between VLC and Helix.

only as player
