wrong audio output and multicast performance

[Magz]

Hi,
I've got a problem with vlc. I'd like to stream a tv broadcast per multicast to severalt clients.

The command line is:
vlc -vvv v4l:/dev/video:norm=pal:frequency=154250:size=640x480:channel=0:adev=/dev/audio:audio=mono --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=768,ab=128,vt=800000,keyint=80,deinterlace}:std{access=udp,mux=ts,url=239.255.210.81}' --ttl 7

I have a IBM Netvista PC as Streaming Server. The sound doesn't come over the net, it comes from the internal speaker. What goes wrong? How can I redirect the sound to the net? I tried aumix for changing the source but there is the same error.

Another problem is the multicast performance. The Vlc Client crashes after about 20 sec. I have increased the udp caching value to 5000 but the client loses pictures. How can I increase the stability ob the client? Is there anything i can do with the network parameters for better performance?

Thank you very much
Magz

[BigBen]

Well, about your audio issue... Are you sure recording is set to line out (not only playbck) and recoding level is high enough

About yout craching issue... Is the log you sent reulting from a crash ? I can only see VLC exiting cleanly...

[Magz]

Hi,
intermediate the sound works. It was a mixer problem, but the sound is broken and not synchron.

The biggest problem is that the player crashes after about 10 seconds. The sound goes into a loop and dr.watson writes the following log:

There are many posts about crashes in the mailing list, but no solution. Are there any recommendations?

Thanks.
Magz

I fixed a nasty bug in the audio transcoding yesterday so could you try to compile a CVS version and check it is working fine for you ?

Ah and for the win32 client, can you give a try to:
http://www.videolan.org/pub/testing/vlc ... -win32.exe
Or even more recent:

Hi,
I've just tested last client compilation from yesterday 12/4.
The client doesn't start. It crashes with drwatson at once. With latest vlc server I can't see a picture.
Meanwhile I have localized the crash problem. When I start old client with --noaudio there is no drwatson. New Client 0.7 from 12/2 also runs fine but without audio.
No idea what I can change in the settings or in the server commandline ...

salut
Magz

Try "-A waveout" to select the waveOut audio output plugin.

And you can also try to update your soundcard drivers.

[Magz]

Great, with -A waveout the client works. It sounds that the sound is a little bit too fast. Sound is not continously. It sounds "choppy", can't describe it exactly .

Do you have any new idea how I can make the sound better ... more continously ??

so long
Magz
