Streaming UDP multicast

Postby Christof » 09 May 2008 10:41

Hello,

At the moment I am working on a project using Cisco Digital Media System (http://www.cisco.com/web/solutions/dms/index.html) for the use of digital signage. Small boxes (Cisco Digital Media Player - ) serve as a mini-computer where the 46" screens are connected to. One of the parts of this digital signage is the streaming of a business channel. We chose VLC media player on a Windows 2003 server for inputting the TV channel using a Pinnacle TV tuner card and streaming an UDP multicast stream. VLC works like a charm, however for further tuning the system I would like to configure it in a more stable platform e.g. after a reboot VLC starts on it is own etc. and have some questions concerning the setup.

I use following command:

Code: Select all

"C:\Program Files\VideoLAN\VLC\vlc.exe" -vvv -I rc --ttl 12 dshow:// :dshow-vdev="Pinnacle PCTV 713x Tuner BDA Analog Capture" :dshow-adev="Capture (Pinnacle PCTV 110i Cap" :dshow-size="320x240" :dshow-tuner-channel=74 :dshow-tuner-country=32 :dshow-tuner-input=1 --sout=#transcode{vcodec=mp2v,vb=512,scale=1,acodec=mp3,ab=128,channels=2}:duplicate{dst=std{access=udp,mux=ts,dst=239.255.42.12:1234}}
1. Warnig messages

When using above command I get in a pretty constant way following warnings in the logging window:

Image

What does this mean? Can I minimize this warning?

2. Service/startup command

I read some info of installing VLC as a NT service. However when ticking on the box of NT service, I cannot see VLC in the Windows services. How does this work? Is the service still available after a reboot?

3. No capture possible

Another option is to configure a startup command (with above parameters) when the server starts, however after a reboot I do not get any image available. I read somewhere on the Internet that VLC cannot capture any image before another application (I uses Unreal Live Server - http://www.umediaserver.net/umediaserver/download.html) first initiated a connection towards the TV Tuner card. This seems to be true, can someone verify this is normal behavior? Is there a workarround for this?

Thanks in advance for any answers!

Regards,

Christof

1/ Increase cache.
2/ THis might be broken, so for it from a .bat file in startup.
3/ No idea.

1\ Thanks, this did the trick ;-)
2\ I tried to read your sentence several times but I cannot find out what you mean :-) Can you clarify a bit?
3\ I did the test and after the reboot and I got no signal. When opening the video feed with Ureal there is no issue. If this is normal behavior I cannot set up the streams without logging in, so that's a bummer. Nobody else a clue or a tip here?

Thanks for your answers allready j-b! Waiting on more clarification on the other ones ;-)

2/ You should create a .bat file that launches the VLC with the correct options. Launch this .bat script at startup.
3/ Still no idea... :'( This shouldn't happen, but you have to ask the manufacturer of the card.

Christof,

Curious what kind of box, hardware specs, you are running vlc on. We're looking to do something similar and push out to about 20 TVs.

I too am in a similar situation like you re: digital signage. Can you give me some pointers. Could you tell me if you were able to get this project done and what was your setup?
