Video working but simple G.711 not?

Hi everyone,
I've got a Problem using VLC. I have a Windows Machine and a Linux machine. The Linux machine is for VLC Server using the Command Line only. The Windows machine is listening at udp://@ . So I've already made a successful stream with mpeg and wmv (with picture and sound). Now I just want to make a simple wav only stream heaving G.711 a. But I didin't get it to work. I tried many codes like:
vlc -vvv sample.wav --sout '#transcode{acodec=alaw,samplerate=8000,channels=1}:duplicate{dst=rtp{dst=linuxmachine:1234}}'
but without success. Is there anyone who could help. I didn't find any in the wiki or in Forum.
Do I have to change something on the windows machine?
thanks

I assume you did not read the Important notes in the 0.9.0 news.

I've got 0.8.6c. Isn't g.711 supported in this version?

I assume you are not trying to open an RTP stream with the raw UDP receiver...

both alaw and ulaw doesn't seem to be supported in vlc 0.9.0. But I thought they were?

I'm having the same problem:
Code: Select all
[0x7f41d0005ba8] main mux error: cannot add this stream
[0x7f41d0001338] stream_out_rtp stream out error: cannot add this stream to the muxer
[0x7f41d00376c8] [Media: cam1] main decoder error: cannot create packetizer output (alaw)
MultiFramedRTPSource::doGetNextFrame1(): The total received frame size exceeds the client's buffer size (65536). 6097 bytes of trailing data will be dropped!
Same with Ulaw:
Code: Select all
[0x7fea340372a8] [Media: cam1] main decoder error: cannot create packetizer output (mlaw)
And G.726:
Code: Select all
[0x7f78400376e8] [Media: cam1] main decoder error: cannot create packetizer output (g726)
This is my vlm.conf
Code: Select all
new cam1 broadcast enabled
setup cam1 input rtsp://admin:admin@192.168.0.164/0
setup cam1 output #rtp{mux=ts,dst=localhost,port=1234,sdp=sap://,name="ch1"}
control cam1 play
Any ideas?

You cannot do G.711 over TS. No big news here.
