RTP compatibility: VLC & Asterisk

[erotavlas_turbo]

Hi,

I don't know if this is the good section of the forum. I use the following command to stream audio/video from VLC to Asterisk

Code: Select all

vlc Asterisk_logo.jpg --fake-duration 20000 --sout '#transcode{vcodec=H263,vb=800,width=352,height=288}:duplicate{dst=rtp{dst=10.36.1.6, port-audio=15004, port-video=19146}}'

In Asterisk side I get the following notice and I can't hear see the stream.

rtp.c:1790 ast_rtp_read: Unknown RTP codec 96 received from IP

Where could be the incompatibility?

Thank

Asterisk can't know what payload number 96 means unless you provide a correct SDP. You'd have the exact same problem from VLC to VLC.

Hi,

I have the following problem. Vlc sends rtp streaming to asterisk it resends the streaming to a softphones connected in a conference. If the bitrate parameter vb is too low the received video is corrupted. If there is only one member/softphone, a value of vb = 200 kbits is sufficient. As the number of member grows, the value of vb necessary to see a correct image grows.
Where could be the problem?

Thank you
