I'm using vlc 1.1.9 on an ubuntu 11.04 machine.
I'm trying to get an rtp stream and send it to stdout where it will be used by asterisk for a music on hold application.
Some time ago i got it working but now I started a new machine and I can't really remember what I did...
The command I'm running is:
Code: Select all
vlc-wrapper rtp://@:5004 --sout=#transcode{acodec=ulaw,ab=64,samplerate=8000,channels=1}:std{access=file,mux=raw,dst=-}But when the audio is played on the softphones, there's a repeated noise while the song can be "recognized" in the background.
Here are the messages shown by VLC:
Code: Select all
...

Could anybody tell me how to fix this?
Thank you!!
